i have two uv dark lights the type you see in night clubs and make
anything white glow in the dark would these harm my two bearded
dragons and my corn snake if fitted in the viv for viewing at night?

They probably wouldn't "harm" them, but they're not going to be terribly
beneficial either--generally they're not set up to produce the "correct"
wavelength of UV needed to process vitamin D3/calcium.

And lo, Chris McMartin didst speak in rec.pets.herp:

IIRC, "standard" UV lights like the ones you find in clubs and fun-houses
produce too much light at wavelengths similar to those blocked by the
ozone layer, and can damage your pets eyes over extended periods of time.

I'd play it safe and use a reptile-safe UV light. They aren't that
expensive; I even bought a spare and I'm still using the first
incandescent one I bought over two years ago. :|

They produce only UVA.

This is the less harmful wavelength range of the UV spectrum and there is
also plenty of it in sunlight. The intensity is however quite high, as the
full output effect of the tube is UVA. So it might be harmful to the eyes
anyway. It is indeed a totally unnatural type of light.


Hmm, incandescents does not produce any UV except a small amount of UVA. UVB
is almost nonexistent, too weak to be useful. Good UVB sources are the
ReptiGlo or ReptiSun tubes. I tested a ReptiGlo 8.0, it lasted 15 months at
12 hours daily before it burned out, and the UVB output had only decreased
less than 1% when it died.

Yup. I only use the incandescent one to light the tank at night. I think
that's what the OP was asking for anyway. I use a ReptiSun fluorescent
during the day.
