Item No.: BS-A19BLK
Some types of black light are used for special effects in discotheques. This type of lamp is of no use to reptiles. Other types are used for various industrial purposes, for example, in sterilizers. This type of lamp can be positively dangerous to living creatures, including humans, as they emit UV-C which can cause skin cancer and eye-damage. The only "black light" which is of any use to reptiles for D3 synthesis are those specified as "BL" types. These emit both UV-A and UV-B radiation at a relatively high level. They have been used successfully with many species of reptile, but high output UV-B full spectrum types are generally preferable. Black lights tend to emit an unpleasant violet glow, and provide no "daylight" frequency light whatsoever. They should therefore only be used in combination with a true full spectrum tube.
