:I thought that some had a 6-8 month warantee? Must look into it further. Do you use them in conjunction with another uv source or as a primary (aside from natural light).
Yeah the Wild Inside bulbs cost me $45 too. They have a warrantee but from what I understand they deduct the time you have left on the year in terms of % and you pay the rest. I didn't want to do that because I'd end up paying shipping every 2 months too. If these ZooMed ones (http://petguys.com/-097612450110.html @$33.99) last then it's cheaper then getting a fluorescent UV every 6 months and the regular heat bulbs. Plus you only need to buy the standard Incandescent fixture. You don't need to use any other UV source with them at all.
