UV Bulbs.

I've managed to find and old UV CFL in the back of one of my cupboards and was wondering if I added that to my light collection what would be the effect on the chilli plants? Would the UV light burn the leaves?

UV light causes burns.

so not benefit at all?

I read an interesting article not to long ago about UVB light causing an increase in trichome production in cannabis. Something about it being a defensive reaction, sort of like a suntan to UV light.

No clue what it would do to peppers.

Peppers like bad conditions. I'd try it.

hmmm. just been reading... and i think it obviously depends on the type of uv rays given out. not entirely sure what my bulb does.

200 - 280 nm --- UVC ultraviolet range which is extremely harmful to plants because it is highly toxic.
280 - 315 nm --- Includes harmful UVB ultraviolet light which causes plants colors to fade.
315 - 380 nm --- Range of UVA ultraviolet light which is neither harmful nor beneficial to plant growth.
380 - 400 nm --- Start of visible light spectrum. Process of chlorophyll absorption begins. UV protected plastics ideally block out any light below this range.

How can light be toxic?

I understand that it could cause the plant to produce toxins, but light contains no chemicals, so far as I know.

Take a plant to the tanning salon and see how it likes it!

Many forms of radiation, including light, can be toxic. Depends upon the dose.........
