I have this bulb in a large ceramic heat dish for my 75 gallon beardie tank. Beardies have to have UVB and this is the most affordable UVB out there and the quality is incredible. Just don't forget to change every 6 months to keep effective. This bulb keeps my big beardie happy:)
I bought this today for my russian tortoise., because his other one blew, and he didn't have UV Raysfor about a week and i put this on him today and he just climbed ad tried to get closer too it! He was just so happy i guess, lol. He looked like the light perked him RIGHT up!! This product is a great product ad i RECCOMEND it 100%! P.S i didn't think this light would be that fat, LOL!
