Lighting -------- Ideally, it would be advantageous for all captive reptiles to be housed in such a way that they could be exposed to and benefit from direct, unfiltered sunlight during the daylight hours every day. This represents the healthiest and most natural situation. Unfortunately, this set of circumstances can rarely be fulfilled by hobbyists because it is neither practical or possible. The next best solution is to use an artificial ultraviolet light source rather than fluorescent or incandescent lightbulbs. One or more Vitalites (Duro-Lite Lamps, Duro-Test Corp., Lyndhurst, NJ 07071) should be used to illuminate the enclosure during the daylight hours. To approximate a natural photo-period, it is best to supply 10-12 hours of daylight and 12-14 hours of darkness each day, with a gradual increase in the number of hours of light in the spring and a gradual decrease in the fall and winter months.
