50k lm is quite high. What electric power consumption does it have ? I estimate around 500 Watt, am I right ?

>>fix4fu+2F7
It's 60k lumens now, and it draws 580W off the wall

>>sberen+1I7
Am I right in thinking you're dissipating that 580W using passive cooling only?

Impressive if so - every time I've designed something approaching that power level I've ended up needing forced air cooling.

> Q: Does it get hot/how is it cooled?

> A: It's cooled through our large heatsink and ultra quiet Noctua fan. The fan only turns on above 75% brightness. At max power, the heatsink is cool enough to put your hands on it for a couple of seconds.
