You could just purchase stage lighting.

Stage lighting fixtures use the halogen metal iodide bulbs that he salivates over at the end, and already solve all of the issues he outlined. They provide their own ballasts, are metal shielded, use a lens that acts as a UV shield, have built-in cooling.

In fact the only issues with stage lighting:

1) The cooling wasn't designed to be silent (it isn't expected to be near someone in a near-silent environment)

2) The lamp casing wasn't designed to be near anything flammable (they get very hot)

3) The lens and casing is designed to throw the beam in a very small angle of spread over a reasonably long distance (they're not designed to point at your face from a few feet)

But given that, it seems reasonable that one could put it farther away and reflect it into the space you want lit.

And if he really wanted to go crazy whilst staying with LEDs, then he could just get a few of these: http://pulsarlight.com/products/chroma-range/chromaflood200/ which are used in architectural lighting and each one produces 10k lumens, and they are safe for indoor and outdoor use, are waterproof, and can be driven from standard mains power.

There's another issue with stage lighting, which is that they draw enough power to flip most residential circuit breakers and possibly to cause electrical fires as well. You're looking at 500W per lighting unit; 575W for the more modern ones with bluer hue. Most theaters are specially wired from the mains to a bank of "dimmers" that safely provide at least 2000W per circuit.

That should be no problem in Europe, Australia, etc. There are portable 3000W appliances, like kettles, heaters and (Old) vacuum cleaners.

Not an issue for newly built apartments, perhaps, but I've been living in an old one for the past year and the electricity is just really poorly done. I've had the circuit breaker fail on me while doing laundry (1kw) and warming up some pancakes in the microwave (1kw). And that's without my neighbour being home, as (go figure) we're on the same circuit breaker.

Do you pay for his use or does he pay for yours? Or is the circuit breaker somehow before the mains panel? (Which I find hard to imagine, but then again your situation is already quite strange.)
