Reptile UVA UVB Mercury Vapour Bulb Lamp,Screw Thread,125 Watt

I just got this bulb and I plugged it in immediately after is arrived; my new baby turtles haven't gotten any UVB since I got them due to insufficient light source, plant aquarium bulb which provided UVA but no UVB. Along with an 100 watt infrared bulb they have begun to bask and I have noticed their energy level has increased and they look happier. This bulb is awesome!!

So far it's excellent. We'll see what happens over time.

Generates heat and UV, perfect for my tortoise. He loves basking under this during cooler winter months.They have some sort of safety shutoff. If I accidently bump them too hard they shut off. But when the timer I have them on resets the next day, they seem fine.

Just purchased this to replace the Evergreen brand one that just did not seem to be putting out much heat. I was disappointed to see a brown dry residue of something permanent on the center of the bulb which would not remove with s soft dry cloth. After putting in my ceramic lamp holder, I tested it for 30 mins. The bulb never got above 85 degrees (same problem as the other bulb I had) and began to emit a strong hot plastic burning smell. I immediately turned it off and I am sending it back for a refund. Very disappointed that not only does this bulb have poor heat radiation but it apparently may be unsafe too. As soon as I put the Evergreen one back in the lamp holder, the smell went away so it is definitely the bulb not my lamp holder that is at fault.

The bulb burst the second time i turned it on.
