So i got the Fluker’s black nightlight incandescent bulb for overhead heat as i know they dont really bask so i think one that gives off barely any light should be good, but all the fixtures i can buy for reptile heat bulbs say to use with an r-type bulb the one i have is the only one sold around here that gives off basically no light that i can afford. Am i risking a fire? Its just a different shaped bulb, the fixture says 100w max and the bulb is 75w. Heres a pic of the exact products. it should be okay right?
