There’s an incoming typhoon here, so all schools are canceled today. :grade:
Out of boredom, I decided to hook up a Luminus SST-90 LED from my Trustfire X6 onto a CPU heatsink.
Setup:
LED: Luminus SST-90 (Probably a poor bin from Trustfire X6)
Driver: DX Buck driver modded to XX amps. Link here. (More about this below)
Power: 450W Computer PSU 5.0V line
Heatsink: Intel Core i7 860 2.8GHz LGA 1156 Socket
DMM: Fluke 117 in series to measure output current.
I got the driver for a laser build, but realized that it’s diameter was 5mm wider than advertised, so it didn’t fit the pill. It was also outputting 2.35A instead of the advertised 2.0A, so that was another nono :puzzled:.
I did some research on swapping the sense resistors to control the output current. (thanks Tech Junkie for helping me out)
I had a bit of free time and took apart my Trustfire X6 (such a beast) and extracted the LED. I hooked it up to the unmodded DX driver but was not impressed. I didn’t have any suitable SMD resistors, so I shorted the sense resistors together to achieve maximum output.
Voilà, it outputs just around 6A to the LED; it didn’t go as high as 9A, but better be safe than sorry, right?
Some pics:
It runs pretty cool I would add. The heatsink’s around 40-45 Celsius (104-113F) when running in high mode.
The setup lights my entire room pretty darn well. I don’t have anything to compare it to unfortunately.
Can you get a picture of the st90 AND another light together? That way we can actually get a sense of how bright it is. Without anything to compare to beamshots are useless unless you want to see the beam profile/colour.
I have a DWDiver (from CPF) driver in my SST-90 mag. I opted for the 10amp/5amp driver, but I am pretty sure he mentioned that a 13amp option could be done.
