Can CFL tube light be used as a UV source to make PCB?

I don't have ultraviolet source to expose PCB. I want to make PCB using UV expose method. I think normal home use CFL will produce UV? How long should I expose in this UV source?

What you said will work. Boards I've left under flourescent lights have eventually exposed but that was more by accident than design.

It's possible to use exposure to sunlight to make a PCB. You just need to make sure that the PCB face at right angles to the sun.

You want to take a strip of PCB, mask it with a piece of thick card and leave a little bit of board exposed. Exposed 5 minutes then move it by another 1cm. Keep going until you've exposed the last part of the board.
