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.
My mum's house is from 1905, but had to be required when she bought it in 1980, and there's no problem running everything in the kitchen at once, plus many portable heaters. We did this at Christmas a couple of years ago when the gas heating broke. I can't remember ever tripping a breaker.
My apartment's main breaker is rated to 50kW, with the oven and hob and laundry machines on 3-phase power, and several 230V 16A circuits for lights and sockets.
