When I bought my beardie, his breeder recommended this all-in-one bulb which had everything my guy needed. So I purchased one for $75. He said that they can last up to 18 months, but to be sure to replace it after that b/c they lose their effectiveness after so long. Well, mine has lasted, and I need to replace it. But, after reading this forum, I went online to look up Mercury Vapor bulbs and found some for only $35 at http://www.bigappleherp.com/Pages/Product/261800.html
Is this what I need? I've only bought what he told me before, and this doesn't look like what I have. It also doesn't look like it will fit into my light casing.
Help, anyone?
