I vote for that they are a rip off. This is a case of the emperor has no clothes. First only vegitarian animals rely on sunlight for D3, an iguqna for instance. Reptiles that eat other animals will get enough D3 from their diet. That said, the ability of artifical light to produce D3 synthesis is far less than natural sunlight, and unreliable as the spectrum degrades over the life time of the bulb. Most reach their target spectrum only in the first three months if at all. Bottom line, if you own an iguanna or some other vegitarian, get a screen cage that you put outside for some indirect sunlight. One or two hours a week out in the sun during the spring and summer will do far more a grand spent on lightbulbs!
