- Today I tested a powerful 20W zoomable Cree LED flashlight from Lidl supermarket. It has 4 modes and it runs on nine AA alkaline batteries. It has just a single big LED instead of multiple small LEDs. This allows for the zoom function. Let's see what's inside :).

Thank you for your once again very detailed video. I also bought 2 of these flashlights before Christmas. For 15 euros per flashlight, this is a good flashlight and also good for modding. The Led is a Cree XHP 50.2 Led (18W), this is available as 6V / 3A and 12V / 1,5A type, max 2654 lm, max. 165 lm / W. I drilled 2 opposite holes into the aluminum head, in order to be able to open and screw the head better (for the Led driver).I removed the small plastic disk and cleaned the head of thermal grease and glued the Led board back with thermal glue for better heat transfer. As an alternative to NiMh AA batteries 3x Li-Ion 26500 cells would be conceivable (3x max 4.2V = 12.6V). It would be great if when once could reprogram the microprocessor to remove SOS and beacon and add a third very low brightness (moonlight mode).
Thanks for your many interesting videos. You have a nice cat. Greetings from Germany. Wish you a healthy new year.
A few people posted schematic in the comments. So fundamentally you could replace the mode control IC with your own microcontroller. Chances are whatever's on there is either OTP, or a custom or semi-custom IC that replaces a microcontroller used at prototyping/development stages and thus sharing the footprint with a microcontroller.
Happy new Year from Poland!
Over time, I got used to your accent. But please be aware of the different pronunciation of flash and flesh. This could avoid potentially very awkward questions about your Christmas present.
First time viewer here and this is exactly what I first noticed....
I was very.... very afraid this is not a FLASH light review....
Czech accent
This year 2019 found your channel and i will stay subscribed forever. Thank you sir for so much interested information.
When people are celebrating new year, DGW works hard to keep us educated. Delightful. Happy new year.
Slavic accent, cats and electronics. Always makes the perfect mix. :)
Happy new year.
Happy new year to you to!!
@@mr.kovacic Thanks
Sretna i tebi Nova godina

EDIT sorry wrong thread
It's a 6V Cree XHP50.2. This LED is not even breaking a sweat. You can run it at 2 amps and beyond for 2500 lm.
It's nice to see you perform basic math on Ohm's law and explain fundamentals of consumer electronics 😊 I wish I were competent as you are.
"...can withstand extreme shocks"
DiodeGoneWilde: Interestiiiing!!!!
Why an Earth all of these LED flaslights have tose blinking etc functions? I want flashlight with just ON/OFF switch and nothing else. Or at least a system where you can change the function separately and the switch is just ON/OFF switch.
I have a bunch of these - the special modes are accessible on half press of the button, so you can turn it ON/OFF without cycling between the modes that nobody wants. www.aliexpress.com/item/LED-flashlight-Tactical-6000-Lumens-CREE-XM-L2-Zoomable-5-Modes-Black-aluminum-alloy-LED-Flashlights/32696375029.html
I modded one of my flashlight just to remove those blinking and halfbright modes, it is much better with just a single mode. Having a potentiometer to regulate brightness separately would be even better.
SOS
If you're stranded and you need help, a repetitive flickering light will get more attention than just a bright light. Rarely does natural stuff pulses repetitively.
Also why we think aliens will send pulsating radio waves to us.
well these functions are used,then you do crash landing/ship sinks..then you can use it as sos signal..i seen flash light what max distance is nearly 2km..
i seen theys kind inside emergency kit offen
You are so lucky to have such a lovely assistant.
I love your videos, Diode, you're the best teacher I've ever seen!
Nice now I have to tear down my flashlights just to see if the are using a buck regulator. Great video.
Hey i wanted to buy it 1 week ago in LIDL but i refused, glad to see it here :)
Perfektní jako vždy - rozborka a analýza i s "chlupama".
Díval jsem se i na tvé starší videa a tam se pokoušíš mluvit s více anglickou výslovností, ale teprve až když mluvíš "jak ti zobák narost" je to to pravé a má to šťávu!
Hodně elánu do další práce! Těším se.
Veľmi pekné video, náučné a ľahko pochopiteľne :D
Posuvaš sa stále ďalej a stále sa to iba zlepšuje.
Working hard )))
Happy new year.
As you can see this product is so dangerous I shouldn't even use it 😂
Made my day even 1 year later !
Happy New year, and thankyou for everything that I have learned from you.
Very good presentation, the voltage/current/power/energy concepts explained so that even a 14 years old would understand them. The flashlight might be a good deal to reuse the 20W cree led, I think if bought separatelly it would cost about the same and here you also get the buck converter, lenses, batteries, etc.
Šťastný nový rok a pokračuj v tvorbe!
Díky, tobě taky :) budu
Great video as always! Happy New Year DiodeGoneWild! Love your channel ❤
That could be fun project. Turn that flashlight into LiPo powered one. Using LiPo cells with BMS board with charging capability. Also happy new year. Z pozdravom zo Slovenska.
I can't wait for that SMPS teardown!!!!
The worked analysis is fascinating. Thanks for another brilliant video.
Amazing video at the end of the year/begin new year!
You always make very informative videos and I find them very helpful!
Keep up all the good videos and explanations!
You're awesome!
Hopefully you reach 100k quickly! Because you really deserve the subscribers. If i would see one of your videos for the first time, without seeing the subcount, i would probably guess that you have like 600k subs.
Have a nice 2019!
Šťastný nový rok!
Best review video ever... regards from Split, Croatia
I do not know if could be helpful but that is a Cree LED, the 5mm one is the XHP50 .
You can check it in their website, led components/products/XlampLeds/Arrays, look like thier XHP50.2 (more powerful, you can recognize from yellow bulb and the 4 chips), also you can check data sheet, that is pretty cool.
I am waiting a torch with their last model of led XHP70.2 way more powerful, that works with 18650 battery!
I have already treadown some flashlight with cree led and all work the same!
Incredible few days ago I fixed up a power supply 24V but 4.5A model LP2022-24 and now you will looking the 10amps version.
We have the same passion lol.
I will wait with impatience the upload of the video about power supply!!! They are my favorite on this channel please keep doing!
Have a good day, bye!!!
Thanks for identifying the LED :). They could have used 18650's in this flashlight, but with the batteries and a suitable charger included, it would be too expensive for a supermarket...
Nothing gets past the cat... 8-) Interesting video....surprised at the burn marks.
Please do more LIDL stuff. They have many interesting things (which i also buy) and I'm really interested in their quality
Igen.... :"D
I am still wondering why lidl does not sell li ion batteries with a tp4056 charger or something else
Seriously cool calculater, haven't seen one of those since the 80's.
Hiya!
Haven't found this lamp at Lidl yet here in Sweden.
But, at Dollarstore more or less the same as above in your video is sold as an 5W with 6xAA.
Almost 100k!!!! Happy New year everyone!
I like how his excitement grows with the number and severity of warnings in the manual. "Electrocution. Explosion. Death. Eternal damnation. Niiiice!"
I do love that really powerful flashlights are now affordable for normal people. I'd be all over the 'affordable' lights if they only got rid of the strobe, SOS, and let you set the power level for one click on (maybe a switch to tell it to go low or high once I press the cap's power switch). EDIT: Would you be able to fit (3) 26xxx sized lithium batteries in it?
I do love it to :) And I also hate the strobe and SOS. It's possible to bypass the mode chip, but you also lose the low power setting which I don't want to lose. Three 18650s or 26650s are unfortunately too long.
Výborné ako vždy, teším sa na ďalšie videá. Inak rovnaký osciloskop som vymenil za kartón tvrdých Spárt :D
Všetko dobré v novom roku.
Depending on the voltage, you could probably fit three LiFePo cells in that thing...
They r using a buck converter so 3hr of running is true. U can check it by practical, if doubt.
Well explained, i like your style bro,keep it up!
Ha ha.. I like your style sir! (Your accent and verbal inflections adds even more entertainment value)
Happy new year!!! 😊
Happy new year and please lets see how that multimeter can read watts.
Please do this power supply review :D I cannot wait for it :D
Czech supermarkets have all kinds of interesting electronics, but in America they only sell food and basic household products (toilet paper, soap, etc). Literally the most exciting non food item that I have seen at the supermarket where I shop is water bottles.
Have a happy new year!
Quite nice review. I just wish, you would do an efficiency measurement. But I suppose it would be quite low, especially if current sense resistors alone waste almost 8% of power to the LED.
For disassembling flashlights you can try to pull on this zoomable part and rotate it. As this zoomable part grips this led module you might be able to unscrew this without damaging surface.
Happy new year diodegonewild 🙂
Love your videos and cat.
Thanks :)
Not everyone can say that he has a cat that is technically supplied.
And a happy new year.
Happy New Year
Happy new jaar from Belgium , thanks for this great video . 🌟👍🌟
New jaar lol hahaha
Voltage drops while connected so voltage should be measured at that time also. (While calculating power)
I'm guessing it would also fit 3 X 18650 in it or possibly an even wider battery. More realistic capacity of these is about 10.5 wh which would be closer but still not what expected. At very max might find a 12wh 18650.
I thought of using 3x 18650 or 26650, but they are loo long.
Happy new year!
Nice video
Bloody hell, it burnt a hole in my paper!
I laughed so hard :D
Thats niiiiiice!
Your cat is cute
Agreed
There are no non-cute cats!
Happy new year 🎉🎆2019🎆🎉
Happy new year!!!
_so here's my cat, and the power of it is definitely not bad!_ (out of context)
Happy new year!!!
I like your cat with the flat face !
Ahoj, nemyslíš si, že proud skrz ty paralelní rezistory je 1,5A, naměřený na začátku, nikoli 3,5A jak říkáš 16:24 ?
Happy New Year!
Happy new year :')
I hope for next video is about power supply computer, PSU 80+ vs normal PSU
Thanks
Hi, enjoyed the video. I dropped my Cree LED Torch and now it's not working! Is it possible to change the bulb as otherwise it seems fine! Also how to extract the bulb?
I hope Finland's Lidl will have this flashlight for sale some day... I would try to run it with 3 x 26500 Li-ion batteries
lov what you do, Happy New Year......always found it confusing on LED power ratings stated on the packaging, is it equivalent to an XX watt light bulb or does it use XX Watts? ( latter being useless for spec'ing actual illumination ). luminous flux is better, but, ya never know if an integrating sphere was used...or a light meter ...or just quoting the LED mfg's datasheet! Cheers
Do you still have your Christmas present? What does the clamp ammeter do when it sees AC? according to the data sheet the QX9920 should charge the inductor up to about 1.7 Amps and turn off (0.143 ohms 0.25 Volts). The input current should be 1.7 Amp pulses of shorter duration with higher input voltage (constant off time) (at 19:49). Ideally power in should equal power out (I assume the brightness does not change with input voltage). I'd also suspect the measurement at 4:45.
Nice old soviet scope
I have seen many video you can convert your multimeter into watt meter. How
I verry like your vidéos, i French but the explication / language are good not so complicated
I think 9xAA batteries is too expensive for 20w led flashlight.Its cheaper with (2-3)x18650 cells
Happy new year 😊
I thought for sure this channel will have over 100,000 subscribers by 2018 (very close!!) Maybe we see a new PicoScope in 2019?
@ 2:02
"WARNING! DANGER OF DEATH... RISK OF INJURY!... DANGER TO LIFE!"
Is it going to shoot out deadly laser beams?? 😂😂😂 Just hilarious!
I wonder if it would make a nice host for an LED swap and it looks easy to make it into a mule!
Happy new year! Well the Power should be calculated with the voltage under load. 1.5A/9 batteries = 170mA of current from each battery, which should drop the voltage some
This works if the batteries are in parallel; the batteries are in series in the flashlight; so 1,5A from each battery at around 13,5-14,85 volts total; so the power is ~20,25-22,28W
Super video :) !!!
You re the best :))
Shark fin, more like a cat fish :-D
That looks like a dam good torch, how to get lithiums in there, more power ha ha :-D.
And a switchmode to play with, sounds like you had a good xmas.
Lidl and Aldi have some usefull stuff, but aldi has something for say a week then thats it!.
I bought a digital micrometer for £8 (really cheap), they never had them again.
It's definitely a good torch. It seems to contain xhp50 LED. Probably one of the lower efficiency bins, but still good. It would be bloody expensive to run in on Lithium AA's, but this would be very good for an emergency flashlight with a very long storage life. For frequent operation, Li-Ions would be the best, but 3x 18650 or 3x 26650 won't fit, they're too long. Maybe I could remove the switchmode power supply and put just a resistor in it and then run it on 2x 26650 in series. The SMPS would run on 2x Li-ion too, but at a low power. It could also run on 3x AA Li-ion and 6 dummy cells, or it could be rewired for 9x AA Li-ion (3S3P). Here we have no Aldi. Lidl also has those things for one week and then they have different things. Once I bought their 19W E27 LED and I was waiting a year before they had it again, to buy another :).
Speak of the devil, i was just looking through the power supply section of your site and up popped your notification, i thought he knows im here lol :).
Ha ha it sounds like Lidl is pretty much the same company, just one week is Aldi's trick.
I think it's done to make you go back every week, just in case you are in danger of missing something lol.
The digital caliper (yes i did take it apart, just had to) would have cost 30 to 40 pounds elsewhere, same basic no-name.
You could use a resistor for dropping voltage, a small wirewound perhaps?
Happy new year
Your accent is very unique! Im serious... 👌👌👌
Wow for a $20 flashlight it has a pretty monstrous XHP led in it. Flashlights in the $70 and higher range typically use those chips.
I think that the LED is the lowest efficiency bin. If the data on the package are right, 1500 lm / 20W = 75 lm/W. This is why it's cheap :).
@@DiodeGoneWildthats an xhp50.2 quite a high-end chip from CREE from memory on the datasheet it can do like 2600-2700 lm at 20w so it definitely isn't a cheap chip, they've just underrated this flashlight by the looks of it.
Seems like a decent device, the machined case and all. Is the main lens made out of glass?
I doubt, it would be dangerous if shattered
Can I please have a link to this product thanks and happy new year! 🎆🎇
It's probably not going to help you much, but it should be this one: www.lidl.de/de/livarno-lux-led-stabtaschenlampe/p290542
I wonder if this can also work with 26650 lithium batteries
Is the nine AA battery holder the same size as three D type cells? If so would it last longer on the D cells, and if so how much longer?
Well done man love your videos!
Šťastný nový rok :D
Happy new year 2019 !!!
happy new year!
>>> Typ na experiment: Co zkusit vzít dva +- stejné MOTy, jejich primáry přendat na jedno jádro a tím si vytvořit oddělovací transformátor?
Under 1.5amp the voltage of the batteries is droping way under 14 volts, so the power is not close to 20wats
hey diode, can you check if 18650 will fit & work in this body? It has this AAA adapter so I assume it could work with 18650 right away as in other chinese smaller ones for 3AAAs but just to be sure - this seems like quite good hardware actually.
No, it's too short for three 18650s.
DiodeGoneWild What about finding some decent Li-ion AA batteries and either modifying the battery holder for a 3S3P configuration. Or maybe just use 3 batteries and short out the rest?
a real pity that. Well thanks for checking anyways.
Isn't that 'mystery chip' just an atmel microcontroller, because of the 6 AVRISP pins probably for programming the chip in the middle of the board.
happy New Year
I have a similar product from Aldi-UK which uses 4 X C cells. I wonder why this one uses AA?
hi i bought in lidl I noticed that after 5 minutes of use batteries getting hot why?
