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

580W

It's 60k lumens now, and it draws 580W off the wall

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.

Whats the expected life for the leds at that power draw level?

		LEDs are pretty insane these days - the ones we use have an L90 (time until they hit 90% brightness) of >50,000 hours (17 years if you use it every day 8 hours a day).

Good estimate, the official website for the lamp says 580W
