The Repta Cera Heat are an economical and enviromentally friendly way of heating your pet reptile. They don't give off any light, so are a great source for diurnal Reptiles preventing disruption to normal night time sleeping patterns. These Ceramic Heat Emitters must be mounted inside a mesh coverto prevent the accidental contact between the bulb and your Pet Reptile or yourself. The surface of these bulbs can exceed 200oC. Reptapet 60 watt available only. Larger watt size available in URS products.
