Shirley, Annapolis MD on 2015/05/27
Best UVB Bulb!

Reptisun is touted by many professionals I know to be the best UVB bulbs readily available in the US. I agree, as I have now used them for years with my chameleons, mostly rescue, for whom an exceptional UVB is required, as many are deficient in calcium due to lack of UVB exposure. is beyond amazing with their service, shipping, packing of these delicate bulbs, and price. I will never shop anywhere else as long as Pet Mountain stocks these.

Good bulb

Bulb works good and is at a great price. Only thing I don't like is, it gives the water a green tint.

Kelli, Tulsa OK on 2012/05/12
High Quality, Great Price

We've been using these bulbs for years, but just recently found the BEST price at The bulbs themselves are great quality and keep our beardie healthy and happy. And they last for years.'s prices are outstanding and their communication and service are fantastic.

Cheri, Tallahassee FL on 2011/12/08

Perfect lighting for Chameleons! Remember to change them every 6-8 months as they lose their UVB rays over time.

Always reliable..

Pet Mountain always has a wide variety of options for all my needs. I always shop around for pricing and each time I come back to Pet Mountain. There products are also packaged where I don't have to worry about things like lights being damaged. Thanks for making the maintenance of my aquariums easier.

Great Price!

Ordered the ReptiSun bulb for my aquatic turtle's tank, (replacement) Your price beat all the other website/dealers out there, and your shipping was economical and fast!

Judy, Westminster MD on 2010/01/12
Great UVB Bulb

We bought the 5.0 for a bearded dragon we rescued. She is over a year old and had never had UVB, so we wanted to introduce it slowly to her. We'll keep this on her for a few months and then upgrade to the 10.0. We can already see her yellow and orange coming out brighter.

Jim, Marietta GA on 2009/10/17
