This lamp is Mega-Ray top-of-the-range Narrow Flood Lamp which has been shown in tests to produce similar amounts of UVB to natural sunlight! - along with adequate heat to create a basking spot at the recommended distances, in many circumstances. This Mega Ray Pet Care Lighting™ original design provides the necessary UVB, UVA and heat for your UVB-dependent basking reptiles. MORE UVB - BUT SAFER Our Mega-Ray Narrow Flood Lamp produces more UVB than other true Mercury Vapor Floods, yet is safer for owners! Our design directs the majority of the UVB from the face of the bulb, rather than diffuse it across a 180° angle. LONGER USEFUL LIFE Using cutting edge technology coupled with five years of dedicated research and testing, we have conquered and significantly reduced the huge decay rates so common in other Mercury Vapor lamps. While other bulbs decay as much as 80%, our newly designed SB bulbs decay less than 30% over the life of the bulb.
