UVA (not B) lights

[nepoez]

Hi I recently switched from a MVB with UVA and UVB rays, to just a row of 3 50watt flood lights as many recommends. I kind of like this setup, but now I'm worried about having no UBA(not B) lights. I read the UVA makes lizards more active and awake. What are your thoughts?

All lightbulbs emit UVA.

Hi, you can use a normal household fluorescent tube for supplementary lighting (or two of them), the object is to have it close to normal daylight (you can also use the "Arcadia" T5`s). Quality of light is important, I see too often people just using the basking lights and nothing else.

UV sensitive cones in tetrachromat lizards peak at around 360nm. There are actually no commercially available household bulbs that also produce significant levels of wavelengths this short that I'm aware of. Health and Safety regulations (in the UK at least) require damaging UV wavelengths to be blocked from normal use bulbs (through the thickness of the bulb glass or special coatings).... UVA seems to also get blocked along with the shorter wavelengths however.

I'd be extremely interested if you do know of cheap bulbs that produce UVA light though!!
