Zilla Incandescent Spot Bulb Day White 150W - Reptile Basking Heat Lamp

The Zilla Incandescent Spot Bulb Day White 150W provides focused lighting and heat in a concentrated area, creating an ideal basking spot for your reptile. Designed to simulate the natural daytime photo-environment of a desert or tropical habitat, this bulb delivers a focused beam of heat and light that heats the opposing surface, creating a direct basking spot for your reptile.

Made from glass containing rare earth neodymium phosphors, this bulb produces a brighter, whiter light. It emits energy across all visible wavelengths from 400nm to 700nm and UVA rays from 315nm to 400nm, supporting a more naturalistic terrarium environment. For UVB output, pair with Zilla Desert 50 or Tropical 25 UVB Fluorescent bulbs.

Sold individually - 1 bulb per package.
