Query: barely gave off heat!!

I couldnt get a TRex 100W flood so i thought i'd give this bulb a chance and i was totally not satisfied. Only 13" from my tortoise, the Zoo Med bulb was only giving off 75 degrees of heat.Within 2 weeks i had replaced it with the TRex which gives off 95 degrees of heat at the same distance and has a longer output of UVB.
