I've heard that snakes can't see red, well I don't know who said that because my snakes sure react to one of those laser mouse things when it is near their cage. If they can't see red then why do they see this thing moving? As for the lights, go with normal lights like at home depot or anywhere else. The night drop is fine, some even say it's needed. So unless they have to have a most specific night temp go with normal light bulbs.
