So what does the commercial unit cost?
What is this going to be used for?
200,000 lumens, 2 hours run time is never going to be cheap. That's 3000 w-h of batteries, not to mention 250,000 lumens of LEDs, but the LEDs will probably be cheaper than optics and everything else.
I expect anything commercial would be quite expensive.
How many are you planning to build?
I haven't really found anything viable. Just things in the $5-10k++ range that's non-battery operated and comes on a trailer.
When I say 200.000 lumens I'm referring to raw lumens and not outputted (losses included). I'm not sure this will be enough anyway.
But now I have stopped looking because it's quite fun building.
Use case is a sport-activity in nature far away from a power-grid. Activity area ~50x50 meters. But also at least 50m away from the mast.
Plan is to build 6 of them initially and the scale up from there.
I already have the Cree CoBs so I will probably mix and match between the reflector type and the lens type lamp.
Reflector one works more like a flood-light given the amount of spill. Also tried a Fresnel type lens from Ledil but I'm not sure I trust the 90% "efficiency rating".
