I built a powerfull CANDELA MONSTER!
it is made of 4 x 15W ostar led supplyed to 18.5V and 2A.
With calibrated proper equipment i measured 10klux+ and at 2m i measured 2600lux. I used a old celeron cpu heatsink to cool down them and that work great! With these, a normal 100W bulb seems to add only a bit of light in the room!
