I have had very bad experience with Exoterra light hoods!!
I bought 3 once, one didnt work right out of the box, and the other 2 crapped out within a few weeks!
I also had a thermostat that died after only a few weeks!!
There stuff is very poorly (cheaply) made.
Like I posted before, if it's electrical, and made by Exoterra, dont buy it!!
I would contact Todd at Light your reptiles to see what hood he recommends.
