“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.
The Staten Island Zoo currently uses the Zoo Med 10.0 High Output UVB Lamp with a number of lizards, including such sensitive species as the Crevice Spiny Swift (Sceloporus poinsetti) and the Texas Horned Lizard (Phrynosoma cornutum).”
