I am currently wiring heating for a closed chamber tortoise enclosure. I wa spreviously going to suspend some typical dome lamps, but noticed that the zoomed deep some lamps have dozens of negative reviews regarding sparking and fires from them. I'm now looking at the Exoterra wire lamps. Plan to use a 100w CHE in one, and a 65w or so flood light in the other. Any thoughts on exoterra lamp quality?
