Exo Terra Infrared Basking Spot, 50w
Any lamp that produces heat produces infrared. Infrared light is not red-colored — actually, it's invisible to humans. This bulb produces the same heat as a standard heat lamp, except the light is tinted red by colored glass. While red light isn't as visually disruptive as blue light, the fact of the matter is that using this style of heat bulb will wash the enclosure in an unnaturally red hue, which interferes with a reptile's normal vision.
If you're looking for a nighttime heat source to boost your reptile's air temps at night, we recommend a lightless heater like the Exo Terra Ceramic Heater instead.
