Zilla 11988 18-Inch Tropical 25 T8 UVB Fluorescent Bulb, 15-Watt
Standard terrarium bulbs canâ€™t deliver the heightened levels of UVB radiation native to a tropical habitat, leaving rainforest reptiles deficient in a vital component of healthy bone development. Tropical 25 Bulbs correct this deficiency with a full dosage of UVB (25 microwatts per second/cm2) along with essential UVA light. As a bonus, Tropical 25â€™s full-spectrum visible light output helps bring out subtle colors in a reptileâ€™s skin that makes everyday viewing more dramatic. Tropical 25 capability is built into R-Zillaâ€™s complete family of high efficiency bulbs for most types of fluorescent fixtures (compact, T5 and T8.) Incandescent bulb users also have the option of a Coil Bulb that fits a standard light socket. Tropical 25 bulbs are designed for 3500 hours or twelve full months of average use.
