The Zoo Med ReptiSun 10.0 High Output UVB Lamp is a specialized 48-inch fluorescent bulb designed to deliver a powerful spectrum of light, including essential UVB and UVA wavelengths. While traditionally used for reptiles, this lamp offers unique benefits for advanced saltwater aquarists, particularly in promoting vibrant coloration and supporting the photosynthetic needs of specific corals and macroalgae in refugiums by closely mimicking the natural solar spectrum.

This high-output lamp is engineered for superior performance, emitting effective levels of UVB up to 20 inches from the bulb's surface, a significant increase over standard models. It provides a spectrum consisting of 10% UVB and 30% UVA, ensuring deep penetration even through screen tops or canopies which can filter out a substantial portion of essential light wavelengths. Manufactured in Germany, this bulb is built for quality and consistent output throughout its lifespan.

This lamp is an excellent choice for the dedicated reef hobbyist with a large or deep aquarium system who requires powerful, specialized lighting. It is particularly beneficial for aquarists looking to fine-tune their lighting to maximize coral pigmentation or for those maintaining systems with light-obstructing covers. Its strong output ensures that even in deeper tanks, corals and other photosynthetic inhabitants receive the full spectrum light they need to thrive.
