Course you can! Look up "quantum well" structures. Laser diodes work because you get to write your own version of, if not the laws of physics, then at least re-write the physical properties of materials.

Not in the UK, but if you have aircon running, it becomes a problem. Every Watt-hour of heat from lighting costs you three Watt-hours: the one you wasted making it, then a couple more to get rid of it.

Darn looking at too many CCTV illumnators recently ;-)
