• Source of radiant heat (infrared light)
• Up to 3,500 hour bulb life

Radiant heat is critical for providing reptiles with a healthy habitat. If a reptile is not provided with appropriate environmental temperature range (ETR), it cannot regulate its core body temperature and may be more prone to chronic infections. Ideal ETR varies from species to species; consult your pet professional for lighting recommendations for your pet. Flukers Black Nightlight bulbs emit low levels of supplemental UV radiation to provide the heat reptiles need during the night cycle.

The sun produces three types of light: ultraviolet, visible, and infrared. UV light helps in regulating behavior and stimulating Vitamin D production in reptiles. Visible light is the spectrum of light that allows humans and animals to see within our environment. Flukers 5.0 UVB and 10.0 UVB Sun Glow Coil Bulbs generate both UV and visible light and should be used in combination with Flukers incandescent light bulbs to mimic natural sunlight.
