Zoo Med T8 ReptiSun 5.0 UVB, 18"

UVB light, a vital component of natural sunlight, is crucial for the health of most reptiles. It supports strong bone development and contributes to various other important bodily functions.

The Zoo Med T8 ReptiSun 5.0 UVB is a premium T8 linear fluorescent bulb crafted by specialists in Germany. It emits a moderate level of UVB, ideal for reptiles with lower UVB needs in shorter or shallower terrariums.

Usage Guidelines:

Mount the 18" Zoo Med T8 ReptiSun 5.0 UVB in a 20" Zoo Med ReptiSun T8 Terrarium Hood and position it above the basking zone. This bulb is most effective for low-UVB reptiles in wide terrariums measuring approximately 30-36" in length.

Ensure consistent UVB performance by replacing the Zoo Med T8 ReptiSun 5.0 UVB every 6 months. For optimal monitoring, pair it with a Zoo Med Digital UV Index Radiometer or a Solarmeter 6.5.
