What leds are these?

240m?!

Distance ratings are mainly advertising junk... I'd need bigger pics to tell what LEDs those are, but I'm getting nichia 083s? It says excellent color rendition.

"Excellent color rendition" means nothing as well. No numbers given.:shakehead Who can tell?

They're claiming 120W for 72 LEDs (3 panels with 24 LEDs on each), or about 1.7W per LED, which is a relatively odd number (?)

It doesn't look like enough heatsink for 120W worth of LEDs to me...

I think there will be enough heatsinking. The weight is 6kg so lots of mass and those big finned blocks mounted verticly have a good low thermal resistance even with no forced airflow you get a good convection curent going. They are not driving the leds too hard sounds like 500ma which help with the efficentcy. They are not cheap 1622 euro for that big one at somthing like 10,000 lumen. I think the selling point will be the low mantance and the durability, adding forced cooling would not do the MTBF any good. Fans are always dodgy components compared to the rest of the system.

No idea what the led is.
