Quig, it will most likely have no negative effect. I know a number of keepers who keep ordinary incadescent bulbs on 24/7 w/out any ill effect on a long term basis. Remember, in a captive setting, burms are typically not subjected to "real" sunlight but cue into subtle photoperiod types of cues. An incadescent bulb is no more "sunlight" to a burm than if the burm was sitting next to a campfire on a dark evening....its still artificial.
>>Rob, I was wondering if using a red light for an overhead heat source would affect a creatures day/night schedule if left on 24/7? I've seen zoos that use this during the day for observation by the public. Just curious, so was looking for some input. Thanks.
