Zilla Reptile Terrarium Incandescent Heat Bulb, Night Black, 50 Watts

Ideal for tropical and desert habitats, the bulb provides ambient heat in which the photons emitted by the filament never escape the dark tint, heating the air inside the enclosure to create the warmth needed for a healthy reptile environment. The bulb is made from glass containing rare earth black phosphors, which simulates the moon‚¬„s natural glow for nocturnal viewing without disturbing the reptile‚¬„s day/night cycle.
