Huge 30W ceramic core LED light (with schematic)

- One correction to make. I said and wrote 220uF for the main capacitor instead of the actual value of 22uF. (I was already thinking about the parallel 220nF capacitor when I did that.)
Just like the other lights made by Sansi, this was a beast to get apart. Lots of plastic bits tightly clipped together. But once it was apart I could see the logic behind their assembly process.
The main feature of this lamp is the custom ceramic core LED modules to help take the heat away from the LED chips. There is a bit of redundancy built in as three parallel sections of 12 LEDs are used per module. The buck driver is a classic type found in many LED lights.
Each module has a voltage of about 36V at about 160mA.
I bought this from a UK-eBay shop, but they appear to have eBay shops in other countries too:-
The price has gone up significantly since I bought this one.

Whoever designed the molds for that deserves a raise.
Industrial engineering tour-de-force for a screw in LED.
When your talent and ability is beyond your current job placement. Over qualified and underpaid for sure
In a year or two this will be done by AI in 5 min. If not already today. Will look very different then.
I think the computers did it. The designed 1 led segment and replicated the rest.
Look like Corona Viruses embedded in snowflakes.🥶😮💨 😄
Looks like the Magic Roundabout in Swindon!
Engineer: "Hey boss, how many molded clips do you want to hold this lamp together?"
Boss: "YES."
I used to work (in electronic design) for a boss who was a bit like that. But his favourite answer was "medium". Often caused a chuckle.
@@simonstroud2555 *lagom*
"Sorry, there was a typo - it was supposed to be 10 clips, not 100 clips"
This reeks of being designed in-computer and directly 3D printed, then presumably molds were made. I love how very different it is, it feels like something from the near future.
nah, it's just a different time zone... 😹

I think it's a future where metal heat sinks are unavailable. Probably a bad one, future that is.

@@clown134 Getting pedaled communist nonsense by a female unknowingly criticizing a communist product is absolutely hilarious. Good job.
Sansi (三思) is an interesting choice for a name. The direct translation is thinking carefully (or deep thought).
But it also might allude to Wu Sansi, a rather colourful figure during the Tang dynasty... a brilliant man, able to navigate the highest levels of power during a time of coups and counter coups and coups to counter the counter coups... times, that usually get people like him "purged". Add to that, that he apparently had "relations" with the Emperor's concubine(s) and wife(s), then "deep thought" becomes a Hitchhiker's Guide reference.
Actually there is a 400 year old novel about all this... one of those books that unsatisfied house-wives keep in their drawer, right next to their "best friend with batteries".
I've had one of these about a year. It's been on a 12/12 cycle for my tropical plants non stop and has held up beautifully. I have another as my bedroom light as the quality of the light is beautiful
"tropical" plants he says, Tomatoes? jajajajaja this guy. That being said I have a handful that I use as spotlights for houseplants, I've been surprisingly pleased with these. They seem to be brighter and less surprisingly hot than a lot of my regular LED Bulbs around the house.
@@knibknibknib yeah that's what I have them for. Much nicer to have in the house than the blue/red ones. That pink light makes it look like a strip joint. Or so I am told, I've never been to one
@@murunbuchstanzangur Degenerate here, can confirm all of that.
"nicer to have in the house than the blue/red ones" I have some of those in a storage shed, bought on clearance and intended to confuse spiders into never thinking it the right time of day to make webs. That didn't work, and the light is dizzying with my prescription lenses handling the two peaks with different focal lengths. It doesn't help that one is largely UV, tripping the filter coating and making anything off to the side of the lens extra bright. On video it looks like Twitch stream lighting. In person it's really unpleasant. Coming out into daylight everything goes green. Looking in from outside the cartoon purple pink glow makes me chuckle.
@@murunbuchstanzangur LOL!
I like the 'chinesey lamp tester' but I do miss seeing the power factor for these various lamps.

These Sansi lights are really interesting; I may buy one. To me, the intricate molded ceramic is at least as interesting as the lighting and electronics. Thanks for featuring these and explaining how they're designed !! (ceramic would have a thermal conductivity roughly an order of magnitude higher than plastics)
I had 4 they all melted themselves
@@IVAN_ENT Not suprised, they don't look reliable. Ceramic is not that good as heat dissipation material. Also three parallel strings without individual current control is asking for trouble. The design is flawed imo.
@@blg53 "Ceramic" is a wide field, there are ceramics like aluminium nitride or cubic boron nitride that have thermal conductivities in the range or even better of copper or silver.
We have some of these, and they work well. They have to be in open air (no top hats or other enclosures). We have them in ceramic lamp sockets in the garage, and they are reliable in that application (and very bright).
I don't have this exact model but I am running the 27W 3000K 4000lm dimmable as my main light source at home. I had 3 of them in my living room and it was like having a mini sun. Having such a bright light improved my mood a little bit. I am running them since September 2021. Now I moved and I am trying to figure out how to do a smart home installation while keeping those extra bright Sansi bulbs.
I also have a smaller 15W Grow Bulb that I have on a timer and use for jumping spider terrarium. Plants inside grow really quickly.
You are so close to 1 million subscribers on TH-cam! I would love to see a bench tour as well as where your regularly used tools live and maybe some more dangerous experiments.
Yes we need a workshop tour ……pretty please
Perhaps a compilation of some of Clive’s more destructive investigations 🤔🤣😫
I'd like to see how to repair an LED desk lamp which has capacitive controls that gradually failed. It's pretty bad to chuck this out, when I'm sure there's probably a simple fix. There's no obvious fault, and my skill set is meccy than leccy :(
I've got eleven 22W and 27W Sansi lamps fitted in external lanterns. They've been in for almost 1 year, approx 4000 hours, and so far had no failures. The manufacturing quality, efficacy, CRI/colour and light output are all excellent.
No wonder these are relatively expensive, the plastics complexity is impressive. Cool to see something new and interesting on the market.
They were less "relatively expensive" before BigClive posted his reviews to Patreons, and the Patreons in turn snapped them all up at normal prices. By the time we got the videos (1 MONTH later!) the prices had been gouged beyond belief.
Pay twice (once to Clive and once to the eBay supplier) or miss out forever (at least at a decent price).
So much *stuff* in these things, they look like little plasto-ceramic space stations.
I have two of these. One of them is four years old and they are on 10 - 14 hours a day n still going. Oldest bulb has survived three falls from ceiling height. I grow orchids and these work great to supplemental light source as I live in a cloudy rainforest. These are also great as natural light for photography.
Legend has it that if anyone still has the original CAD model of this lamp, if you were to try to change any feature on it and update the model, the computer would combust in flames..
Eventually, well-worked CAD models do that anyway.
Good to see these on your channel, they’ve been keeping my indoor citrus happy and thriving all winter in New England.
I had 3 of those 40 watt Sansi lights, 2 of which went blinky blinky after a few months, last one still in its box. I have since gotten slightly smaller 25 watt ones that have not failed yet, powered on a AC smart dimmer plug. The smaller ones were bought in Feb 2022, so they have lasted over a year without any problems so far. There was some slight flicker on the lowest power, under 30% though, changes between 2 brightness levels only changing luminescence 2 or 3 times a minute. Looking forward to watching this on my watch later list to see what they look like inside.
Out of all the wack LED lamps you have taken apart over the years, this one definitely has to be one of the most interesting ones, those LED modules are something else. Also, those little lightbulb test units are very tempting to get LOL. I don’t need any more stuff though, I have enough crap haha.
My order of their lamps arrived yesterday. It's about time someone started to make things that are more complex than the basic crap. Thanks for the effort. Keep working and good luck!
So it's not just a light. It's also clip art....😊
Awwww man, taking this thing apart was so complex and interesting!
These LED modules are very interesting, being made of 3 strings each, connected in parallel. Since they're all run from a constant current source, if one string in the module fails, the rest have harder work to do having to conduct 1.5x their normal current each, which leads to premature failure... or maybe, on the contrary, delayed failure? Typical of any parallel-connected LED strings, nothing new here.
Small correction: the buck current is a sawtooth, not constant. By applying a rectangular voltage to the inductor, it integrates the voltage, which is ramp: i(t) = 1/L * int(V)*dt, where "int" is the integral. So if V(t) is a step, then the current is a ramp. By using a large-value inductance, you force the buck to operate in the continuous mode, which is advisable to reduce EMI. In continuous mode, you get a sawtooth current waveform through the inductor, which is passed through to the LED load.
Super futuristic looking design with lots of ventilation slots and very well constructed with more clips than I have ever seen in in a light housing array so cool! Clive an interesting video,thank Ya!
Mind boggling amount of plastic engineering and manufacturing involved. Fascinating to be sure.
Thank you yet again Mr. Big!
Got to love those cheap LED drivers, when I switched my kitchen strip light off that's on the same circuit, it blew the capacitor living room LED light.
So now I'm fitting an 8 bulb pendulum light, with changeable bulbs, blow that you sod.
Yes I ordered 1 of the rgbw floodlights and 2 arrived this morning. Nice and weighty. Not plugged it in yet, but it claims 70w...
I ordered one of the 100w RGBW units and 4 arrived!! Consumption measured at 51w max but still very bright, terrible to look directly at, also it's only RGB, no W chips. Someone at their shipping centre needs to learn numbers 🤣
It's very odd. I wonder why they send out multiples.
@@bigclivedotcom It’s a cunning stunt!
@electroshed You’d think that the Chinese would be good at that sort of thing
My SO picked Sansi and has been pleased to see bigclive confirm the choice.
Wow! Thanks for the reviews BC !! Got my lights today -- ordered 1 received 2 !! SANSI 27W LED Light Bulb 250W Equivalent 4000lm A21 5000K God are they bright !!! The 23W 5000°K lights we've been using in my wife's ceramics studio are 2650 lm. At 27W, 5000°K these Sansi lights are a whopping 4000 lm !! And, they sent TWO! Thank you so much for bringing these Sansi products to my attention, Big Clive !! They are most definitely the "pie-eatin' basturds" of LED screw-in illumination !!!
I’ve been a fan of this brand for YEARS. Glad to see you finally found them!! They are the BEST! I just hope the prices doesn’t go up.
too late..... LOL
Very nice Lamp seems quite well built
Sansi has a 27w ceramic light here in the States, and it is somewhat like a corn cob light, but they have a 30w like the one you dissected. They have a range of other ceramic lights as well.
Where are you finding these in the U.S.? I am interested in them... Thanks.
i couldnt sleep, so thank you clive for keepin me company
In addition to the clip fetish seen in the design, the thermal flow looked well thought out to me - keeping most of the LED waste heat away from the driver board.
A corner of my garage needs a new light, and all of those clips sound fun!
The Sansi lights are awesome, I've been running both the 15 and 30 watt versions for over a year now. Really can recommend them a lot, they are by far the best engineered, compact LED grow lamps I own.
That begs the question what is your second best?
Maybe they sent two because they thought you might destroy it trying to get the bugger apart 🙂
I have a few of these (and the 15w version) keeping my tomato plants happy, they've been working on a timer for 8 hours per day for over a year with no issues!
Impressive construction!
This is so good put together. All those clips everywhere, you don't see that many in cars these days.
I'm glad I'm not the only one who sometimes breaks things when I try to take them apart!
Such a beast of a lamp
I found an Ebay listing where these are being billed as a replacement for incandescent spot/flood lamps. Their option selection is odd, the 30W/200W equivalent is $19.31. The 30W/200W two pack is $11.49. they have an option for 30W/200W NEW for $8.27. They also have a 40W/300W for $24.83.
Great disassembly and break down .
I love your videos Big Clive, you're the best
Thanks Clive. Interesting lamps, if they weren't so expensive I'd be ordering me a few...
Same, I really like the idea of these, but they've been price gouged.
They were less expensive before BigClive posted his reviews to Patreons, and the Patreons in turn snapped them all up at normal prices. By the time we got the videos (1 MONTH later!) the prices had been gouged beyond belief.
This happens on all of BigClive's recent videos, beware! Pay twice or miss out forever!
@@TheSpotify95 I guess that we can always wait a month or two for the sellers to have dropped the prices again.
@@Shaun.Stephens I'd you want something similar, I actually stumbled across Walmart branded bulbs of all things that fit in standard sockets. They put 4000 lumens each for only 30 watts which is pretty nice. I only paid 8 dollars each for them and some of mine have been running for about 6 months now it's no problems. For dedicated plant grow lights I use mars hydro branded products, they are high quality Chinese made (surprisingly) that shio out of California. They have some basic models that run as low as 65 dollars for a 100 watt actual draw full spectrum grow light, but have a whole range of more premium products too. I personally love the SP150 which are usually around 90 each and draw 140 watts but are much higher quality. I'm not even sponsored, I just LOVE plants so I have over 10 different grow lights and my home looks like a greenhouse 😂
@@iamjustkiwi Thanks for the info James. I'm in New Zealand however so, with freight costs being what they are it's likely the Chinese options are still cheaper for me. Cheers.
I want to install these in every single socket at home! 😍
Too bright!! Lol
I know that these would work well as directional lighting in areas with tall ceilings, so that the light could spread a little!
The killer clips of overkill.
VERY well designed. I think this thing could fall out of a 60 foot high ceiling and survive almost if not entirely intact.
0:37 "Great, it works, now... let's drop it" 🤣🤣
This lamp must be in with a chance of winning the annual 'How much plastic can you connect to an E27 fitting' award. I love the technology of LED lights, not so much the waste involved with them.
At least plastic is recyclable, so you can shove it in the green recycling bin (or whatever color your recyclable waste is) once the LEDs fail.
Very neet Led Setup on this light very unique
Very Well Made.
Ooh! Posh schematics! And covid-like enlargements! This is Jackanory for techie nerds. Wonderful vid as always. Thank you!
Holy crap, something I actually have! I have three of these in my bedroom, keeping the jalapenos and peppers alive for the past few years. I cant believe It
I have one with 7 of those ring cobs. Works great for my plants 😁
I use a couple of these growing chillis, they are very good.
These are actually great for beginner indoor gardeners . Very hot tho so make sure you have a good exhaust and airflow .
Cob led's are really good but if the heat isn't properly dealt with they can burn out quickly .
They always do... I've never had much luck with large COBs lasting much past their 1 or 2 year warranty. 😒
Clive, that looks like genuinely good engineering - very rare from China!
It's Chinese know what a vandell you are do send2 giving you1to use!!😅 great channel to watch, learnt a great amount from you,love your analysis of the ccts! Spent hrs watching you Clive many times in bed,better than book @bedtime, you've got a very soothing voice!🤗😘🌹
There are cord connected floodlights with these odd LED modules in them as well and Sansi make them up to 100W for the US market. I have a pair of their 50W units with a 4x2 array of the modules each; they seem to make decent work lights.
To call iit elaborate, is somewhat of an understatement.
This video was very good and interesting, I enjoyed
@Clive I suspect that's AlN ceramic, which is Aluminium Nitride. It has amazingly high thermal conductivity for a ceramic, and of course equally importantly it's non-conductive, and relatively cheap at under a dollar a kilogram.
fascinating construction, thanks for looking into it! btw: they last very long in my case (2years 12h a day)
I'd love to see a "Big Clive Designed" sort of open source LED bulb. Decoupling all of electronics/leds/heat sink/structure, such that any of the four can be replaced. The beefy, pricey heat sink, and the structure itself can then be sufficiently robust to be "100 year parts". I'm positive the LED part can get to ridiculously cheap and mass-produceable. The part I fail at is figuring how *precisely* to do the 120/240 -> DC part in a way that none of those electronics will be a failure point and yet also small enough to basically fit in/around the E26 screw part.
I think I have seen their lights before here in a store because I remember seeing motion flood lights with those LEDs in them.
Hello from the cheap seats. Looks like a cool lamp.
This has to be one of the quirkiest channels on TH-cam.
I liked the Xledia lights more than the Sansi, but last time I checked Amazon, they were no longer available. I still have all my Xledia lights that I bought 8 or so years ago and they still work great.
What are the odds it's the same company or the same people behind it.
@@Convolutedtubules I think Xledia was Japanese. No idea what Sansi is.
@@aaronsj80 I'm probably mistaken, just throwing ideas in the wind.
These lights like quite interesting and refreshingly well designed compared to a lot of the chineseum that is around at the moment
These are really good last long
If I were a Chinese I would be shipping a pallet .
The last one of these bulbs was pretty interesting and they probably had a surge in sales. A reverse image search would probably find your video.
I'm currently sporting a dhall bulb from b and q in the studio, neutral white filament pearl glass ,100w equivalent. (Nice light I can recommend)
I have never seen this kind of bulb in France 👍👋
Dune II (Game): "Construction complete"
Clive: "The destruction is now complete".
I think each one of those modules in a homemade light would be a neat project now that you have a crimper to make the end caps.
I would imagine a lamp like that would be full of bugs, the insect kind. They certainly like to fill up our lampshades.
Awesome Video big clive
I bought a few SANSI 100w equivalent 1600 lumen LED bulbs last year. (model c21bb-te26-13w)I have installed a couple of them, one in a table lamp and the other in a ceiling fan. This bulb has a dual concentric array of leds almost 3" across (37 leds inner circle)..It has flow through ventilation slits that should limit the buildup of heat. My gripe with most LED bulbs is they run them much to hot and that drastically cuts their life and the light output drops off as they heat up. The result is your 100w equiv bulb only puts out the same amount of light as a 60w equiv bulb once it gets hot.
Min is built similar to yours and all that ventilation increases the life and I find the light output does not drop off as much when they get hot. I've only had them in use for 6-7 months but ther much better than the run of the mill crap bulbs you usually find for sale.
I have seen this lamp in a DIY market in 2 versions, dimmable and non dimmable. The internal circuit will be built up differently and would like to see this.
"Hydroponics type industry"
Very smooth ;) clandestine operations require obfuscation in the conditions we are subjected to on this platform
i have been looking at bigclive's page of projects. it is remarkable how our interests intersect-electronics, mains electricity, booze, long hair on our heads, and explosives/fireworks. thanks clive. i particularly like your trick of using 2 resistors to contact the pads on bayonet light fittings.
.oh, and the using of 10o resistors to initiate things is brilliant. it works on model rocket engine as well as the official ni-chrome ones at a tiny fraction of the price.

That wasn't easy! 😂 Good work!
Recently I have been getting interested in lights like these for reasons. Would love to hear your thoughts about different cheap LED plant grow lights.
There are specialist forums that will have much more up to date data on grow lights.
I've got a few Sensi 36w ones and also the cheap Amazon LED varieties. The cheap ones are ok if very close to plants but not that bright, but then they run off a standard USB plug so don't expect anything like the watts and lux they claim. A good quality 2.4amp Samsung works better than any other. But Sensi so much better but very heavy bulbs so need a strong metal lamp fitting. Also get very hot.
I am personally a fan of the mars hydro SP 150. They are 140 watts each and put out a lot of light. I got mine for 85 dollars each (I run 5 in my tropical plant room, have larger 300 watt ones for flowers) and I've been using their brand for about 6 years now with no issues, in fact my first purchases are still in use and working solidly. They're very good for a Chinese brand imo
I wonder how the ceramic heatsinks perform, did you perhaps check with a thermal camera? It seems so much smaller then what I would expect for 30W and aluminium heatsink, I wonder if ceramics is better. Really weird lamps, fascinating stuff.
Apparently isle of man is in a totally different time zone
That's a very interesting lamp once again. If I needed a high power directional LED lamp for E27, I'd get one. Though not at over £25 each, once again the price has been gouged beyond belief. I blame the Patreons who were able to access this 4 weeks before I was.
I'm a sucker for these lamp designs. 😅
Sent you 2? They heard of you. One to take apart and never work again. One to actually fulfill its purpose in life!
"Another order for Big Clive. We should send him two as he'll trash one of them trying to take it apart."
I've been looking at these for a mother room and for the Veg cycle of my hemp.
I wonder if the black coating improves radiative cooling
I think it's more for protection against condensation on the higher voltage bits due to being used in plant growth applications.
I just..haha this channel is one of the best. This and electro boom haha.
Any electrical/electronic supplier is going to be wary of sending product out to someone named Clive on the Isle of Man.
If the stuff's dodgy then they may well "misplace" the order or if it's good then they'll send out 2 knowing that you are prone to tear, at least, one apart.
It looks like a prop from the original Alien film. Somewhat futuristic Aztec look about it.
Wow, a design that let's you replace the LED's? AWESOME... i'll want 20
Considering the immense amount of heat rising though that lamp, I doubt the capacitors at the top will survive even burning through the first set.
Hello from Germany ❤️
When I see a little choke and a little extra capacitor and a little extra resistor I feel the designer had a specific radio signal in mind and wasn't reliably protecting it with just the L and C.
Strange and complex (over-engineered?) construction indeed. I wonder what kind of incandescent lamp it's made to replace? It's too fat for being like a PAR.
Even destroyed, I'd easily find some uses of the ceramic modules alone. Bright, well cooled, can easily be repurposed with a cheap power supply. Neat stuff on their own.
Very satisfying plastic crunching noises, BTW.
I like the spider web in the middle of the light. [drunken observation] 🤘😂
You could make 4W spotlights out of the modules. They will last forever.
Indeed! :D
