UVB bulbs can be divided into linear fluorescent, compact fluorescents, and mercury vapor. In the future, commercial LED UVB lights may also become available. Fluorescent UVB bulbs provide light in the required wavelength for D3 synthesis, but no heat. Mercury vapor bulbs provide both heat and UVB. Mercury vapor bulbs can provide very high levels of UVB exposure and their use should be avoided in amphibians. There are six main aspects to consider when selecting a UVB bulb:

1 Size/type of the enclosure.

2 Type of material between the bulb and the reptile.

3 Type of bulb.

4 Effective distance of the bulb.

5 Bulb longevity.

6 Species of amphibian.

Another consideration is the type of fixture used for the bulb. There are a number of fixtures that offer the advantage of having reflective materials to increase light reflection and decrease scattered light emission (radiation). Reptile/amphibian‐specific light fixtures or those that reflect light away from the bulb and towards the animal are preferred over plastic fixtures or those without reflective properties.
