Super Bright LED Grow Lights Replace High Watt HPS -Best Value: Spider Farmer Dimmable SF4000 Review
ฝัง
- เผยแพร่เมื่อ 13 ก.ค. 2024
- High powered LED grow lights push the limits in both efficiency & overall brightness. This newly revised panel is strong enough to easily outperform 600W DE HPS systems, while consuming only 2/3 the power! When compared to a brand name Quantum Board*, Spider Farmer's grow lights generate more PAR photons (PPF) per dollar spent. A much better value without sacrificing on performance. In this unpaid product review, I measured light levels from my Spider Farmer SF4000 LED plant grow light. These lights were sent at no cost, to take objective PAR readings & demonstrate the new dimmer function!

SF4000 review:
APPLICATION: At 457W of power, this LED can replace a quality 600W HPS system (double-ended bulb in digital ballast). A suitable choice for indoor agricultural production. It can be used in individual tents for stealth grows. Excellent for traditional 12hr flowering crops but also day-neutral (autoflower) crops grown in sea of green applications. The light is great at ambient CO2 levels but also suited for high ppm CO2 usages. It can supply plenty of photons for high yields. Just be sure you select the right tent size.
COVERAGE AREA: Spider Farmer recommends veg: 6x6 & flower: 5x5. The light will work in those tent sizes, but performs better at veg: 5x5 & flower: 4x4. The resulting PPF per square foot would be optimal over that tighter area. But you need to dial things in correctly. That means getting all of those 9 cardinal parameters right: Light, CO2, Wind, Humidity, Temperature, Nutrients, Water, Oxygen & Root-zone Temperature. Just be sure to select the proper hanging height!
TOO BRIGHT??? As noted in the video, some lighting companies are focusing their attention on having the highest PPFD values for their center readings. At a certain point, those readings can be TOO high, resulting in poor plant response. Although plant yield tends to increase as PPFD level rise, the relationship is not linear. At a certain point, you're simply wasting energy, bombarding plant tissues w/ more photons than they can use.
Also, if the center PPFD readings are excessively high, this should not be viewed as a 'selling point.' This simply indicates that the grow light is too close & needs raised higher. The result will be more reasonable PPFD levels that spread more evenly across the entire plant canopy. The SF4000 is so bright, you simply need to raise it a little higher than other lights. I would say that the absolute minimum is 18".
FINAL THOUGHTS: I do highly recommend the SF4000. The added dimming function increases its flexibility. It can easily replace an HPS system & it is a better value that other branded LED lights. Compared to buying two SF2000s, a single SF4000 generates MORE light at a reduced cost. But at full power, it's tremendously bright! So place it at the right height & cover the proper area for your application.
* NOTE: This light is NOT a "Quantum Board". Horticulture Lighting Group (HLG) has registered that term as a trademark. Don't confuse Spider Farmer's panels with actual "Quantum Boards" as they are in NO way affiliated! Alternate terms that could be used instead include: quantum LEDs, quantum styled panels or QBs. Generally, these have a large quantity of LEDs, spread out over a large area, in contrast with point sources like COBs.

At 67 years old I was a big HID guy but after replacing my two 315 CMH with a Mars fc6500 I'm sold , the difference is unbelievable and 23c , cool !
This is the best LED grow light review I've seen so far. Thank you!
Great figures breakdown, very informative, easy to understand and super helpful! Abs love it, lots of really valuable info, excellent for newbies, keep doing more! 👌
Bought an sf4000 I’ll never look back. Best light ever, for the price that is.
Good to know it! :)
Agree strongly.
What are some down-sides to this light?
@@jonbgreen6916 As shown in this video, the light requires a certain amount of vertical height for optimal coverage. This makes it great for commercial growing in an open warehouse style layout. The primary situation where bar lights excel would be for tight vertical clearances like racks. Otherwise, there's really no reason to stay away from this type of light.
Your content is so clear for newbies like myself. Thanks man.
Well Im glad I am not the only person who was shocked at the Spider Farmer's efficiency. It is like staring into a thousand suns.
You are best gardener out there! Keep us in formed Al. I’m a big fan.
I appreciate your support! Thanks so much for watching. :-)
Great job as always. I sometimes refer my viewers to your channel for additional info.
That's awesome! I really appreciate that. :-)
I bought the sf 4000 to grow herbs and it's doing great.i have a fan constantly blowing on the top power supplies to keep them really cool and hopefully make it last alot longer.i bought it because of your review of it.thanks
Love how you reference the 'special' crops :)
heheh, thanks for watching! ;)
Great review. I recently got the SF 2000 and am really happy with it so far.

Hello AlboPepper,
to be honest, I am amazed by your reviews. I searched a lot for different lamps reviews and so on. But no one delivered like you did.
I started to check out your other videos too and wow ... they are so great.
I am so happy that I found you. I studied physics. I am German. I need proper reviews with details, going into the specs. You are the one delivering it. You are outstanding and awesome.
Loves the vid brother! 💕I really need to upgrade from my old budmaster LED!
Love your videos, keep up the good work!
Thanks for watching and support my channel! :-D
Se echaban de menos tus videos.

I just received my SF4000 today, glad I found your video today as I was setting it up. I am a little perplexed as to setting the distance though. My setup is a 4x4 grow tent. I have several items in there but more importantly I have a chili plant in hydro that’s flowering but wondering as too optimal distance and dimmer setting. I currently have it set to about 18in per the manual. Eventually I will move the other items out once last freeze is safely gone for my zone.
Yeah i cant wait till Able get some them new LEDS
Nice stuff.
I have 4 SF 4000's ... they have unbelievable performance for the actual power they pull from the wall..much worth the money
i agree 100%. i even bought one for $400 and it didnt compare to the sf4000 side by side so that mixjoy without dimmer went back and got me another sf. Took me awhile to be convinced about leds but after the results of 2 sf4000's runs I am a believer.
You use 4? How many plants do you grow?
@@brianfyffe8204 the appropriate question would be, what is your square footage. All plants require different amounts of light to flourish. Example, lettuce versus "tomatos".
Nice. I am about to get my first one which will be added to my 3 x phlizon 3000s. Can’t wait to see the difference
How much energy do they pull from the wall , and how much does it show
Hey gracien, just want to say goodluck to you. My community and myself included just suffered a very bad harvest failure, it have been raining non stop here and it caused a lot of flooding that damaged a lot of plants and the one that survive dies from fungal or bacterial infection, it's especially bad considering the state of the world right now so I'm wishing nothing that happened here ever happen to you
Lighting is definitely NOT an issue these days, which makes me happy.
Only issue are the internet-of-crooks.
Very nice and informative thanks a lot:)
Recently purchased the sf4000 very pleased with my investment.
Glad to hear it Shawn! Thanks for sharing your feedback on the product. :)
nice video thanks. really helped me understand

Thank you.
Very good video 👍
Thanks for watching! :D
Another great review and appreciated. Nice job! Might have been an improvement for Spider Farmer to space the four boards out, instead of clustering them for better corner coverage and more even lighting.
Good observation Matt! Yes, spacing out each board would provide more even coverage. That would be most crucial for growers who are limited on vertical space.
Hey Albo, really love the content. I could tell you put so much attention to detail into your videos. I have a question regarding finding the optimal distance from canopy + how hard to drive the lights.
I'm currently using 5 strips of samsung SI-B8VZ91B20WW
in a 4x4'. Each strip gets 100W so total of 500W(max driver can go). I can get same amount of PPFD if 12" from canopy while using 300-400watt as opposed to 20-30" at full 500W. Which would you pick and why?
Thanks
Mint vid
Awesome shirt brother
Thanks man! :)
Nice video with solid info! It's obvious that experienced grower's knowledge exceed the one of an average marketing department employee 😊💚🐛.
Btw. there is some benefit in using two SF2000 (or four SF1000) lights instead one SF4000. With multiple lights you can get more even spread (less hot spot).
Thanks for watching! If your growspace is rectangular then the SF2000s are certainly going to be more flexible for creating uniform coverage. In a perfectly square tent, there's less advantage to using the 2000s. Perhaps if there is very little vertical clearance then the 2000s might work out just a little better. But with a my smaller tent size recommendations, along with sufficient hanging height, the SF4000 will do rather well.
@@Albopepper Yes, you are absolutely right. Like for a 4' x 4' the SF4000 is surely the perfect fit.
Thank you for your wonderful Content as It is so helpful to the new grower. I just purchased a SF 2000 spider farmer light as well as a 2 x 4 grow tent for auto flowers. Hoping you can share with me your favorite light hanging height and intensity on the dimmer knob for the seedling, veg, and flower stages of the plant.
Vids like this one sometimes make me really angry. And all because I can give only one like :P Excellent content, super informative - subbed! Keep up the amazing work
Hi Anna! Thanks so much for watching and for supporting my channel! :-)
Great and honest review as always. I do wish Spider Farmer would come out with linear/rail version (e.g 3"x 4' or 2') that would allow us to change the configuration around for something other than a square tent. Until then I'll just have to keep building my own
I agree! That would be pretty nice. :)
Amazing video tnx
Thanks so much for watching! :)
Sweet
This upgrade is a long time coming friends 👍
I have burned some medicinal peppers with the sf 4000 turned down to two hundred and seventy-five ish Watts. I would have been more prone to turn the intensity back sooner if my light has this upgrade. The very next run I decided to go back to my blurple for veg and save the sf 4000 for flower. It’s a strong light for sure worth the money once I figure the height out better.
Burned in veg or flower? How close was the light?
Is it ok to keep 18 inch in veg/ seedlings but just dim it? And gradually increase at she grows?
@@tect777 Think 24" would be better
albo;great camera@
The fact that you could even get ahold of Samsung to find out the reason for price fluctuations is amazing. Gives me faith that someday I might be able to source leds from them. Hahah JK prob not. Idk if it’s because of Covid but I can’t even get the led stars, or individual diodes to reflow myself that I’m looking for. I just made one 730nm module to add to my HLG650R lights. I wanted to see if I could do it first( never even soldered until now) so I only ordered 21 triple 20mm star mcpcb for a small Slate single QB648 light. I’m trying to go 1:1 wattage wise with the 730nm to Quantum Board total( I know it’s not commonly used at all let alone at this level )
Thanks for sharing the last thing I need to complete my I door growing set up this winter has been the lights so much misleading online it's hard to decide what light set up to buy
I understand Casey. I hope my videos are able to help you out a little. Thanks so much for watching!
the new 2021 sf 4000 has way better light distribution they spread the diodes in the center and packed them in tight around the corners. you can get really good par values on the edge's without getting too hot in the center. glad to see spider farmer taking feedback on their lights and making improvments.
Good to know! :)
Very like your video
Thank-you very much for watching!
@@Albopepper I also plant the production of such a lamp, if the lower prices, better service, consider adding a supplier Well
I have had an older model sf 4000 (dimmer under the drivers) so I’ve used it only at full power for a year now. I grow auto flowers and I’ve come to find out that using it as I have is just fine as long as it is never closer than 20” at any point in the grow cycle. That said, I highly recommend Spider Farmer in general, especially for the price point.
Good to know! Thanks for for sharing Mark. :)
Good to know. Just got the sf 4000 for doing the same thing. I love autoflowers.
@@capecod3475 what's your favourite thing about autos? The harvest time? The manageable size?
@@Kholaslittlespot1 ruderalis 😂
Great video I would like to see you review the new viperspetra sx-1500
I'll have to keep that in mind. Thanks Jerry!
I’ve got 2 of these mounted on light movers in tents. I am very much using them wrong, but because I know how I’m using them wrong, I’m using them “right” for what I’m doing. I’ve got one fixture per 4x8, and have some shadows as it moves all the way. But, i do think this can cover a 4x6 tent on a mover and give the maximum potential yeild the light can with relative ease.
1994 called, wants their light movers back.
What low profile grow lights do you recommend for seed starting on tiered racks?
Your product reviews seem to be for very serious indoor hobbyists that want to fruit indoors.
Do you recommend the barrina leds that look like t8s?
Sylstar is also very good, I run a SF2000 in a 2x2x5 and a Sylstar GL2000 I picked up direct from the supplier in another 2x2x5 and Imo it's just as capable. had some real healthy tomatoes and lots of yield running a single hydro set up in each.(oxy pot)
I just picked up their entry level 110watt light to check it out. The quality control was pretty bad but if the diodes are indeed genuine lm301b then it's very good value. I probably paid less than half the price of the spider farmer light.
What do you recommend dimming knob to be set to in flower?
+Spider Farmer 4K 18 inches above canopy.
My ladies are 3 week in flower and 100 percent happy and healthy. This is my first run with the SPF 4K.
The original way to dim was a total joke and waste of time, but the upgrade is now exceptionally awesome, good save Spider farm I'm buying a grow kit once I sell this guitar on Ebay Australia :-)
Are there any food plants that would do well around the main light footprints also under 12-12 lighting?
I've tested the color spectrum of these Spider Farmer lights using many food plants and all of the plants did well for me. But this model is very high wattage. I'm going to use it for seedlings, but I'll be dimming it way down to 100W. I'm covering a 30" x 30" area. It doesn't make sense to purchase such a strong light and then dim it so low. You just want to grow in a small area, under the footprint of the light, is that right?
My SF4000 only covered an actual 3'x3' area in flower, with the center being way too intense. The outlying 1'x1' area of the tent was a total waste. I replaced it with a Mars Hydro FC4500 that actually covered the 4'x4' and the difference in yield was impressive in addition to being a really good light. They nailed this design and I hope you can test and review them soon.
Thanks for sharing your experience with this model. What you're describing matches up perfectly with what I said in this video. If your center readings were too high and the outer edges were poorly lit, then your light was too close. That's the light physics of this unit. It should have been raised higher for more even coverage. I'm at Mar Hydro's site right now & I don't see anything for an FC4500. But I DO see an FC4800. That type of model is _EXCELLENT_ for even coverage at much lower hanging heights. It should be positioned totally differently than the SF4000.
I don't agree with the specs for the FC4800 though. The Par Value seems to me, to be fabricated. I don't believe this light puts out 1649 umols while drawing 480W. That would mean 3.44 umols/J. I don't believe it. And so I have difficulty trusting their listing...
@@Albopepper Sorry... I confuse the 4800 and 6500 model numbers because I have them both. As for having the SF4000 too close, there are limits to the hanging height inside of a tent due to the wire hangers so I can agree to a point... But even raising that style of light higher will only moderately raise the readings at the edges of the fixture; you simple cannot have proper intensity where there are no diodes which is why I prefer the strip style fixtures. I'm sure the Mars readings are not 100% accurate either, but what I'm seeing on my meter is more than enough for flowering even at extreme levels over the entire 4'x4' area... Which was not the case for the SF4000. Real world, it simply wasn't enough coverage for a 4'x4' growing cannabis to the results I expect.
No worries about the model number! At least I was able to figure out which one you meant. Being physically constrained by hanging height is a real issue. I'm glad you brought this up. Hopefully it will inform others who have vertical limits in their tent size. In your situation, it sounds like you made the perfect choice by switching to a system that has a broad diode layout. What was the distance that you had between the SF4000 and the plant canopy? That info might be able to help out other viewers. No CO2, right?
@@Albopepper Hanging height is a big issue with these kinds of intensity (especially without knob dimming), and this was in a full size 8'x4'x7' tent... The SF4000 was 14-16" from the majority of the canopy, so it was not especially close. I didn't see any bleaching or other signs of the light being too intense, but I could not move the light higher without discarding the wire hangers... We could really use a low profile hanger to make use of the extra foot of space. I don't run Co2 in that tent, but it does average about 600ppm+/- due to it's location inside, so I think I fared better with light stress than would otherwise happen.
Thanks for that! So planning on 18" as a minimum was good advice then. But yeah, custom hanging wires might be needed to achieve it. In my little ghetto grow chamber I had to do exactly that to conserve space. I ditched the OEM wires and used some hanging chains instead.
Hi. First of all this was a very great review. What do you think about the Lumatek Zeus 600 Pro (EU) or the Photontek X 600 Pro (North America)? Would you recommend this light for a 5x5 or for a 4x4? Lumatek aka. Photontek says 5x5 too like they did at Spiderfarmers but i'm not sure if the numbers are good enough for a 5x5. I would really appreciate your opinion.
Thanks for watching! I think you are on the right track for a 5x5 area. The higher output units can achieve higher yield for that larger area. I reviewed a similar product here: th-cam.com/video/PCaesi_M5DQ/w-d-xo.html That style of light is very nice as it allows you to hang the light much closer to the plant canopy.
Is the ballast on the SF4000 removable so that it can be kept outside of the grow tent to reduce heat inside the tent?
Great thing about led is you can leave them on 24/7 which helps to reduce maturity time of plants
Some types of plants can do ok under 24hr light cycles. But not all plant. Many of the high light flowering plants require a 12/12 cycle to complete their reproductive phase. Something to keep in mind.
hokey smokes! that was 169 ppfd readings per chart. so... 845 readings for the 5 charts??? Well done!!!
LOL, thanks! Yeah it took a little time, but the numbers should help people to see the overall light distribution. Hopefully it serves as a useful reference!
If I get my own place, I'm get the 4000 to grow some meds
Should my Spider Farmer sf2000 light intensity be set at 100 power, at the recommended distance or am I supposed to set the light at the recommended distance, but then dial down or up the power depending how the leaves are responding. Not sure when I should use the power at 100?
he only US labor on an HLG is loading the Japanese LED board stuffers and putting quantum boards into a shipping. box. The LEDs and

Indeed. There are no LED diode factories producing grow lights in the US that I am aware of.
@@Albopepper
Thank you for responding ... we enjoy your videos.
btw... can you do a video on how much the
the Samsung/Osram LED fixtures dim over time? For all I know 2 years down the road they lose 20 percent lumen so your stuck with a brick. I want to migrate from HPS
but nobody has done long term. Do have and links to long term test?
Thank you a million,
Mack
The term to search for is "lumen maintenance." The LM301B diodes are marketed for being both highly efficient and also for having higher lumen maintenance vs many other diodes on the market. I'd love to see more info on the topic as well. I've had to dig through various product specification pages and even still, it's hard to get concrete numbers and specs for comparison. I know the Samsung diodes perform very well in this regard, but I have yet to find a complete database comparing multiple diode brands and models, let alone when compared to other tech like HIDs and fluorescents.
❤
so it makes no sense to buy the se 7000 without co2? thx for the videos!
Hey Al what do you think about the new Samsung Lm301h series? Are they better or is it just a marketing strategy?
Hi Lokas. That's an excellent question! I've looked into the specs sheets for the LM301B and compared them to the LM301H. As it turns out, they're the same. You are correct in suspecting that it's all a marketing strategy. The LM301B are rated according to lumens measurements. The LM301H is simply measured and rated for PPF umols. However, they generate the same light!
I’m choosing one but to figure out which one I’ve a question: for auto-peppers 😝 20/4hrs what is the DLI to aim for? 500 ppfd x20hr are good or not? Thx
I've done a lot of research on this subject. Whether you're growing auto or photoperiod peppers, Spider Farmer is the best value for money. You cannot go wrong with them.
overwhelmed, I am looking at a 2 foot square tent, need your top 2 best lights for a small medical pot grow. 2 of the best. I appreciate your insight.
Thanks for watching. This video compares multiple lights that are all designed for a 2' x 2' tent: th-cam.com/video/WmjOSzSF-HI/w-d-xo.html
@@Albopepper Thank you
You should do a review of the Geekbeast Pro 630w vs SF 4000. Which would be better value for money? I understand that the 630 would need to go on a 5x5 due to ppf intensity, but wondering per $ which is the better light for maximum production?
When you compare the total light output vs the cost, both light options offer the same value. So for the smaller 4x4 tents, I would say the SF4000 is ideal (assuming you have adequate vertical clearance). And for 5x5, the Geekbeast model is a really good fit and equivalent in value (PPF/W). The smartphone app is an added bonus too.
Letsa grow!
I replaced 2 600W HPS with 2 of these.
How they working out for you
I’m doing exactly that right now lol but I’m going to keep one 600w hps in with them for now till I see the results 👍
@@trickym5748 I would aswell I'm drawn to these leds but find it hard to not use 600 digitalisation. Hope they do thejob
I recently bought an sf2000 and they have switched to an uneven diode distribution (biased towards the edges); from pictures, they seem to have done the same to the sf4000. Can we expect more even PPFD coverage?
How do I get my hands on the newer model sp1000?
What would you suggest for a 6x10 bloom area
Would you say Id be ok to plug 2 sf4000s daisy chained into a surge protector in my apartment? I have a 4x8 tent that Im wanting to go from seed to harvest in. Any suggestions would be much appreciated.
The surge protector should be properly grounded. Two SF4000s should pull about 920W and 7.6 amps. As long as your surge protector can handle that, then I would expect it to be ok. Hope that helps!
What do you think about BXEN-50S-11M-3C-00-0-0 as grow lights? The 50S model has (according to the datasheet) little bit better spectrum with much lower price.
Hypothetical question: If I make an array of ultra-high-efficiency home-lighting LEDs, like the one you show at 6:23 (say in the 120 lumen per watt category), would these be an okayish alternative for grow-lights? If I supplement the warm-white with a few "special" LEDs, say 395nm or 750nm, would it make growth meaningfully better? I'm not looking for "medicinal" plants, just kitchen-garden herbs; the ridiculously cheap home-lights (2024) are skewing the "bang for the buck" story, imo.
Hey Albo is 20,000 lux hitting my seedlings too much ?? they're not growing anymore ?
I've been tempted to upgrade my medicinal tomatoes grow with spider farmer lights. My grow space is a 3x2 by about 6 feet high. My current setup is older led technologies with the blurple spectrum and fans. What light would you recommend for my space?
I think the SF2000 would work great in that space. Plenty of light. Might even be able to dim it just a tiny dim. But the proportions would certainly be perfect.
@@Albopepper thanks for the reply and the advice. My tomatoes will surely appreciate the upgrade.
;-)
Can you connect more than one together for power or does each light require it to be plugged into a outlet for power?
Each light requires its own individual power connection.
That sucks..thought i seen a "T" where the main attaches to the ballast and could run more than one ballast off one main cord
would you recommend led over hps for better performance + cheaper energy use ?
from New Zealand and were behind in our times and laws ;)
Yes the LED would be an excellent replacement for HPS. But you just need to be sure you are replacing with an appropriately sized light. This LED, for example, would not be a good replacement for a top of the line DE 1000W HPS. Some growers select LEDs that are underpowered for the task and then they complain that the LEDs don't give good yield. But they didn't select strong enough units for replacing their HPS.
@@Albopepper first off i want to say thank you for the respones brother. That is so true , ive had exp growers insist that LED is trash but LED seems to be upgrading with technology and HPS seems to be the same. That makes sense though , what would your advice be on selecting a good LED? ive heard it's better to buy expensive LEDs as they save money in the long run
I brought 2 was working great. For some reason it's been flickering non stop...any solutions?
What would you reccomand for a 500 sq area. Tempted to switch out hps 1k watts
What units? Are you covering 500 sq feet? Is it 22 ft x 22 ft? Are you currently using a 1000W DE HPS?
really nice video. I would like to know if putting one sf2000 with a HPS could be helpful for my ``medicinal tomatoes´´
Sure! Whatever you can do to reach those optimal light levels. :)
Love those "medicinal tomatoes", especially vaporised.
Does anything compete with this light at its current price ($490)?? And does it compare to anything in the $700-800 range?
I get the value prop for buying a light that's twice the size, but not twice the cost, but I have plants that grow at differing rates, and need to use a high light, and a low light, especially w/ seedlings. Isn't this a typical scenario?
Some of the plants might also have different photo-period requirements. If you need a separate veg light, then get whatever works for you.
Are these LED lights applicable outdoor? Please reply, this might be helpful to our thesis. Thamk you
These are not 100% weather proof.
7:51 Shut up and take my money! 💵🤣
😆
So nice to see Luigi is into indoor gardening.
The led light use 110v or 220v? Thanks
