The Super Reptile spiral nebula UVB bulbs are available in a range of UVB outputs and wattages. Please select the required UVB output and wattage from the drop down menus when ordering.

The UVB output helps prevent or reverse metabolic bone disease in captive reptiles. These bulbs have a 30% UVA output to increase appetite and stimulate mating in captive reptiles. These bulbs are made from special UV transmitting quartz glass.

These bulbs are self-ballasted, and a regular screw fitting will power these bulbs no problem. The spiral shape of the bulb enables vertical or horizontal mounting without compromising performance. It is recommended to combine a high UVB output (Repti 5.0 and 10.0) with a very high visual light output (Repti 2.0) for optimal results. Fluorescent bulbs do not provide sufficient heat.

The spiral nebula 2.0 UV output is a general light source with a high visual light output and a very high colour rendering index (CRI), but a lower UVB radiation. This bulb is suitable for snakes, all amphibians (frogs, toads and salamanders) and nocturnal animals. Plants will thrive under this light as well. It is also a perfect complementary light to a UVB bulb to boost visual light.

The spiral nebula 5.0 UV has a moderate to high UVB output, similar to that of shady environments such as rain forests and other tropical locations. Reptiles living in these habitats receive less UV radiation because of the many climatological conditions (fairly high humidity, changes in weather, etc) that prevent direct sunlight from reaching them or their basking sites.

The spiral nebula 10.0 UV has a very high UVB output similar to that associated with desert environments. Desert locations receive more direct sunlight than any other because of fewer clouds, less air humidity and no plants or trees to provide shade. Therefore desert reptiles are more exposed to UV radiation than any other type of reptile. This bulb can also be used on screened terrariums or terrariums with dense screen covers to ensure UVB penetration. Dense screens can filter out up to 50% of the UVB rays.
