Zoo Med ReptiSun Bulbs are the gold standard in reptile lighting. Great quality along with long lasing UVB output make these the bulb of choice for professionals and hobbyists.
A full 5% UVB output allows vitamin D3 synthesis to occur naturally, preventing or reversing MBD and other health problems in turtles and tortoises, Bearded Dragons, Iguanas, and all other diurnal reptiles. The ReptiSun® 5.0 is effective for UVB induced photo conversion of vitamin D3 in reptiles' skin at distances up to 12". Accept no substitutes; get the original reptile UVB T8 lamp - Zoo Med's ReptiSun® 5.0!
"Recently, the zoo's reptile keepers ran some tests in order to measure the UVB output of fluorescent lamps (bulbs) used in some of the exhibits and holding cages... Using a UVB meter, the staff found that the Zoo Med ReptiSun 10.0 High Output UVB Lamp provided high levels of UVB, with the Zoo Med ReptiSun 5.0 UVB Lamp being valuable in some situations as well.
