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

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

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

  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).

      How does the operating temperature of the LEDs affect your projected L90 time?

  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.

      CENELEC Guide 29, referenced in EU harmonized standards sets burn thresholds: For brief contact (e.g., 1-3 seconds on adult-accessible parts), temperatures should stay below ~48-55°C depending on material; longer reflexive contact requires even lower limits (e.g., 43°C for extended exposure). A surface hot enough that hands can only tolerate it for "a couple of seconds" implies it's above this (likely 60°C+), risking second-degree burns. I practice this means this product would not be allowed to be sold in EU. This would have been thoroughly tested to get the CE mark. > All LED lights sold in Europe must carry the CE mark https://wwbridge-cert.com/blog/posts/is-ce-marking-for-led-lights-necessary-for-european-market https://wwbridge-cert.com/blog/posts/is-ce-marking-for-led-l...

        Well, at no point do they talk about any kind of certification so my guess is they just didn't care/know/worry about it. So, yes, it's probably not legal to sell this in many places -not just EU-.

        Honestly, this lamp seems very dangerous just because of this. You'd have to warn guests not to trip and fall onto it, and keep kids away from it.
