This is the short version of the full teardown video of this light, which took longer than expected and was maybe a bit too dark.

What would be an eBay search term be that yields the 4×2 and 10×2 cob modules of the "10" and 20w rechargeable lights? Can't find any with my own terms…

Everything is hackable, especially if you know how to swing a hammer. Thinking on it though, it could be a useful had to add another pair of LiPos in series and feed the LED via a buck converter to maintain light intensity, maybe add a dimming circuit to extend the "burn time". I suppose you have to be a bit tricky with the charging circuit/wiring to have it charge as 2×2 in parallel.

Did these lights come from E-bay or pound land?
Hi Clive. This looks to be a fairly well made LED lamp. Where did you get this from and how much as I'm looking for something like this. Cheers.
Why would they bother potting a resistor? Would it help with heat dissipation or do they just want us to think there's lots of fancy electronics in there?
I had just bought one of these last week. It gives out a decent amount of light, but haven't had the opportunity to really test its run time. I'm surprised it's using only 2 18650s though, they could throw in another 2 in parallel to make it run longer. I'm glad I haven't heard anything about how bad it is though, I should be safe with mine 😛 not gonna blow up on me.
good job!! thanks
So would that LED work on 12v or is that too high a low voltage for it?
This version of the video is pointless! Us electronics-video watching folk almost exclusively like longer videos, and even if we didn't, 20 minutes is not nearly long enough to worry about shortening. Just a thought 🙂
I wondered if you ever tried a mini chinese blowtorch/soldering iron?…I just got one and it is great for field work and browning some dishes ;-), great vids, keep up the good work 🙂
seems like there is room to add another pair of 18650s, mine runs about 3 hours, so it would double, 'if' i can find decent 18650s at a decent price! these now sell for about £15, were £35 about a year ago!
Hello Clive, can I ask you a question ? : I have a 'De Drie Electronics' battery charger it can supply 10A at 24 volts, used for charging mobility scooters and wheelchair. I've recently bought one because i needed a powerful 24 volt power supply. But as I've measured the output, it doesn't work, and i get 0 volts output voltage. Do you have any clue how to turn it on?
