Ordered 3 love them

Dragon loves her light

Great

Great bought it a while ago and still working great

I have a bearded dragon in a 40 gallon tank. I was surprised at how much larger this bulb was compared to my other UVA/UVB light. It has mercury in it, so there's warnings on the package. I don't remember my other light having mercury. But what really kinda weirded me out was that after I installed it, my kid thought the dragon's branch was on fire. But it wasn't. It was, however, glowing blue where the light hit. And when I looked at the dragon, her coloring had changed. I had to take her out of the tank and keep her on me for a while before her coloring went back to normal. I think this may be too strong for my tank. And really, the mercury warning makes me a little nervous.Edited to add: I tried this again recently, because my dragon was looking like she wasn't herself, and the UVB light I had in there seemed weak, and I was reading that a lot of people use lights with mercury. I think she actually enjoyed the extra light, up until a point, and then she went inside her log and hid so I turned it off. I wish I knew more about the technical aspects of dragon ownership. But every time I get a thermometer for her tank it stops working or falls, and I don't know how to judge whether the UVB bulb is too strong, too weak or just right. I'd love to get a reliable temperature gauge in her tank.

Plugged this into my unit and it popped immediately. My electrician was out sor something else so he checked the unit for me before I bought another. The unit is fine, a regular light bulb worked in there - he said it’s this bulb. Amazon shipped it in a bag which I thought was weird. So maybe damage in transit.

From what I can tell the bulb is bright and emits heat well for my bearded dragon babies. I don't own a UVB tester yet so I can't tell how much UVB it's emitting. It screwed into my deep dome reflector housing and fits inside it well. Always replace your UVB bulbs every 9 months unless you have a tester that proves otherwise.

Got this prior to finding out my dragon needed a tube UVB. But it does emit UVB. I don’t know what animal need this type though but it does do the trick of emitting it.
