Frequently Asked Questions

Mercury vapor bulbs are ideal for species requiring both high UVB exposure and basking heat, such as many iguanas and tortoises. They simplify setups by combining functions into one bulb.
UVB output degrades over time even if the bulb still lights up. Experts recommend replacing these bulbs every 6 to 12 months to ensure your reptile receives adequate UVB for calcium metabolism.
While some amphibians benefit from UVA, many species are sensitive to high heat and intense UVB. Always verify your specific species' requirements, as mercury vapor bulbs may be too harsh for sensitive amphibians.
