Quick question for a friend of mine that has an adult iguana and uses ceramic heat emitters (I've no personal experience with this type of heating).

She would like to order a 150 watt one oneline and needs a recommendation for a good, reasonably priced supplier. I've done a bit of googling and found that Big Apple Herp sells one that is black in color and apparently has a greater surface to emit heat from. Is this a gimmick or a good product that is better to use than the more standard white colored heat emitters?

If you use ceramic heat emitters and have a preferred supplier I'd love to be able to pass that information on to my friend. Her one and only local pet store (she lives way up in northern Michigan) rarely gets them in and the last one she purchased was defective.
