The Exo Terra Scorpion Light adds a whole new dimension to the keeping of invertebrates. The Scorpion Light emits a soft ultraviolet light similar to the UV rays reflected from the moon's surface. Ultraviolet light causes certain scorpions, spiders and insects to glow in the dark, illuminating certain spider webs and stimulating the mating behaviour of spiders. The UV ray emitting scorpion light shows you a new hidden world and enhances the behaviour of your animals caused by UV rays. With an energy consumption of only 2 W, the scorpion light uses almost 80% less energy than a conventional night light and allows a natural drop in temperature during the night.
