Multiple LED's that project on top of each other....employing some kind of mirror, lens, or prism set-up? Or just multiple heads. I have a Tiablo A9 lens Aspheric that does over 120,000 lux on 1.4 Amps. 4 of them together aren't much bigger than DEFT. That would yield nearly 500K lux. I can envision a light that has rearward facing LED's that are arranged in a circle. They all reflect onto a central mirror at the back and then are aligned in path as they reflect forward and out the Aspheric lens. I simply don't think 3,000,000 lux is possible with a single emitter. I think that kinda gives the secret away. Has to be more than one emitter.
