Venom Gear provides the very best in care for your reptiles with heaters, lamps, enclosure accessories, and more. VG products will bring out the best in your scaly friend! Venom Gear LED Fan Heat Lamp - compact yet powerful! Halogen bulbs are a great alternative to the standard incandescent globes that are commonly used in reptile keeping. Available in 50W and 75W, these bulbs also emit small amounts of UVB, approximately equivalent to a 3.0. While this small output of UVB is not sufficient as a primary source of UVB, it makes for a great supplementary source in a spot beam at a different location from the primary UVB source, with a blue colouring.
