I'm not sure about those lights, never relied too heavily on them before. The moonlight ones are not infrared though, if I'm thinking of the right ones. To be honest, I'm not sure what they are, they make a sorta bluish light. If you asked me personally, I don't trust them, but then again, I haven't done sufficient research on them to have a legitimate excuse yet. I just use human heating pads for my Ts. If need be, you can attach them to the side of the tank rather than underneath, that should help. Otherwise, if you need to use a light I'd go with the infrared. What's the temps in there anyway?
