I am sorry if you have the bulb and can take it back I would---- I would replace the bulb w/ the Reptsiun 10.0 bulb --- T8-- it will fit your fixture-- and I would put it in your tank 8-10 inches from basking area --- here is a list of brands to stay away from
Brands to DEFINITELY ADVOID buying are as follows : this was posted on the forum Lighting help topic
Nomoy Pet,
Zilla,
All Living Things,
Reptile-One,
URS,
MegaRay Brand,
CrawlMiracle,
Nat Geo ,
Sparkzoo reptispar,
Repti-Zoo ,
NatAll of which are cheap Chinese clones made very cheaply using very poor quality quartz glass and cheap phosphors and next to no quality control or no meaningful quality control ==> very poor UV spectrum produced including UVC and bad parts of the UVB band --- these will harm your pet.ural Selections (in green boxes) .
domestic fittings for T8 and T5 tubes are fine PROVIDED the tube is not covered == the cover will stop all UV.
>>> a slip on reflector or use of a reflector hood is an excellent investment as it will focus and essentially double the UVA and UVB seen by the beardie , and no UVA or UVB will be wasted by radiating to areas inaccessible to the beardie
