ok so i've been having really bad luck with flourescent fixtures and bulbs all together. i've been looking into MVB's and i really want to get one, but when i first got my beardie i was monitoring the basking temps and i was using a 75w ZooMed repti basking spot lamp about 15" from his basking spot, which is a flat rock, it got up to 130F, i quickly took the bulb back and got a 50w and it's now at a steady 103F. i notice that most of the MVB's only come at the lowest of 100w .... please help, what can i do???
