UVA in heat bulb

[devynnogood]

I've been using 2 60w Zoo med daylight blue reptile bulbs for heat in my chameleon enclosure. I never noticed until today that it says UVA at the bottom. I'm pretty good at all aspects of chameleon keeping but the technicalities of lights is still a bit confusing to me. Can anyone dumb down what UVA is and is it too much along with my 26w reptisun UV bulb. I'll attach a picture below of the bulb.

What size is your cage?. Wattage depends on other variables such as the ambient temperature in your house. If 60 is creating a good basking temp within the range for your species of chameleon, then it is fine. I actually use two in my 24 x 24 x 48 cages to give them a couple of options to bask. If your cage is small, it might be creating too much heat at the top of the cage. UVA is just a type of ultraviolet ray. UvB is one also, but is stronger. They definitely need both though

The two 60watts create a perfect basking temp for my cage. My question was mainly what is UVA, I wanted to make sure he wasn't receiving to many UVs.

From what ive read...UVA rays penetrate deep into the skin. The wavelength is longer than UVB at 320 to 400 nm. Exposure with no protection can lead to premature skin aging and wrinkling, and suppress the immune system. UVB rays will likely burn the superficial layers of your skin and plays a part in the development of skin cancer. The wavelength is 290 to 320 NM.

Yes, You are right.. I read about that they penetrate deeper.

Is UVA in all heat bulbs?
