Description: 1. Professional Reptile Heat bulbs designed for a 50W reptile turtle bulb can provide UVA & UVB spectrum light that aids in the healthy growth of turtles. This reptile heat lamp bulb also delivers warmth for turtles and other reptiles, promoting increased activity levels. 2. The reptile lampshade holder is made from ceramic material capable of withstanding high temperatures. The horn shape lamp shell design allows for focused light on the reptiles within the tank. 3.
