Ridiculously powerful LED torch from 445nm

Hi all.

Looking at the threads and from my own experimentation, it occurs to me that one possible use for the 445nm diodes could be to make the world's brightest pocket torch.

All that would be needed is a 445nm diode, driver, salvaged or new blue to green/red crystal from white LED and a suitable lens + case.
Alternate idea, paint a microscope cover slip with green and red emitting phosphor from the Luxprint EL kits.

A stack of these with a bullseye pattern painted on would also work, as each would generate white light without interfering with the main beam.

Does this sound possible?

Obviously this would still be an eye hazard at close range even with the crystal, as laser light would still be present.

Even if you could get similar efficiencies as the state-of-the-art LEDs, 445nm diodes take up to 4W input (to have similar life span). The best you'd get is about 400 lumens.

Also, they're called phosphors, not crystals.
