Do fluorescent lights give off UV rays?
Yes, but it might not be very much. Inside the bulb, the UV is intense and is what causes the powder coating on the inside of the glass to fluoresce. But the bulb glass is often made to absorb most of the UV that gets past the powder. So the escaping UV can vary a lot from one brand to another. You can see the different visible colors emitted by looking at the reflection of a lamp on a CD (see example in link, below). But, of course, the UV wavelengths are invisible. That link also shows typical spectra for a couple type lamps, that include the mercury UV lines.
