At 50-500 watts it would not look to be a good option.Anyone tried quartz/tungsten/halogen lights as a UV source?
If thet are removed from an glass layer, they chuck out UV too.
As this is a electronic forum i think the advice of a bunch of UV leds would be a far better option, as they work very well with pcb and are quick, cheap, and low power.
They give a very consistant results and there is no mains wiring required.
