I'm sure many thought I was reporting a Chinese vendor who was a bit too free with the zeroes but it's actually a real light of sorts made by
Zweibrüder Optoelectronics (I'm hesitant to call it a flashlight even if that's how it's described), although not exactly budget and I doubt it uses batteries (hence the general forum)
Yeah...but pretty expensive ($ per watt). Think one vendor wanted to make even 1kW but it was too costly and idea was shelved. (not sure where did i read it from)
Edit - hey seems like they have come down in price.
I know some of them do customised orders. Usually for things like colours they don't normally stock (but do produce for small LEDs). Price is obviously not good for customised orders. But if anyone really wanted a 1kW one, they may be able to get someone to make one. At that price I'd expect they'd want you to prepay but you probably wouldn't need to order more then 1. At a random guess you'd probably play ~$1000 which is a rather expensive LED.
