Exo Terra Reptile UVB100 Tropical Terrarium Bulbs

The Exo Terra Reptile UVB100 Tropical Terrarium Bulb is a compact fluorescent lamp that delivers the moderate UVB (5.0) levels tropical and sub-tropical reptiles and amphibians need. Its balanced UVB output supports vitamin D3 synthesis and calcium metabolism to help prevent metabolic bone disease, while the UVA rays encourage natural appetite, activity, and behavior.

FAQ

Which wattage should I choose?
Use 13 W for small and standard terrariums; step up to 26 W for larger or taller enclosures that need more output and coverage.

How often should I replace it?
Replace roughly every 12 months. UVB output fades over time even while the lamp still produces visible light.

Does this bulb provide heat?
No, it is a UVB lamp and gives off little heat. Pair it with a basking bulb to create a proper warm spot.

What fixture does it need?
It screws into a standard dome fixture. A ceramic-socket dome is recommended for heat-tolerant, long-term use.
