ALL flouresent bulbs emit UV light. All of them, even the screw in mercury bulbs.

Some tubes emit more UV than others. Bluish daylight bulbs will work virtually as well as the really expensive verilux tubes.
I have a tanning booth salon light system but its UV light is so far off the chart that I don't use it. It would actully burn your retinas if you looked at it.

Polycarbonate clear plastic panels will block over half the UV light of all flouresent bulbs. Other plastics or glass will not block UV nearly as well.

I use a combination of a pinkish grow light and the blueish daylight bulb in 2 living room tube fixtures and it is a very pleasing red blue full spectrum. I even accent those with 3 blue neon fixtures and one pink neon lamp. Downstairs I use Yellowish floursesents for a warm golden light.

I hate the stark white blue bulbs alone.
