In 1993, Zoo Med developed the 1st UVB lamp for reptiles; this changed the way all zoos, herpetologists, and hobbyists keep reptiles in captivity. The ReptiSun UVB/LED is their boldest and most advanced UVB lighting option yet. It provides your reptile with crisp white light, UVB, and UVA all in one lamp, and lets you enjoy the energy savings that cutting-edge LED lighting delivers. State of the art Japanese made UVB diodes are protected by a high-quality UVB-transmitting quartz glass cover with durability and longevity in mind.
