I bought this http://www.thatpetplace.com/pet/prod/209726/product.web for my 20g shellie tank about 6 weeks ago and yesterday the 10,000k bulb burned out already:angryfire:. Does anyone else know if any 24"/14w bulb will work? And anyone else have this happen so soon? I'm tempted to write and/or call them to complain. Or should I call the store where I bought it? Thanks for any help.
