light sources?

[darkfather]

does anyone know of a cheap efficient (ideally greater than 80%) light source? I'm after one for UVa 315-450nm and one for green light at 520nm +-20nm. The ones I have looked at so far are neither cheap nor efficient. I need a fairly intense source preferable (in the order of watts rather than milliwatts)....

We use lamps from this company

Everything from 20 watts to KW's.

Not sure what cheap is to you, they are fairly inexpensive when you put them into a machine that costs $$$$$

Hope this helps,

How about multiple LEDs?
