The Oz Moon Nocturnal Heat & Light Globe, size G95. Viewing your reptile at night with an ordinary daylight bulb can alter your animal's perception of day length. This results in your animal becoming stressed and can lead to sickness and disease. For a better alternative and a more natural approach to watching your reptiles at night, try the new Oz Moon Nocturnal Heat & Light Globe. It is a moon-shaped, moonlight-simulating bulb that emits a moon glow. Your animal will be more inclined to carry out its normal behaviour. It also has the added benefit of emitting heat. Especially good for nocturnal animals that are elusive during the day.
