Mega Ray Mercury Vapour

The Mega Ray PR80 is a mercury vapour bulb that combines UVA, UVB, and heat output in a single E27 lamp — a practical solution for keepers who want a consolidated lighting and basking source. Available in a range of wattages to suit enclosures of different sizes and species requirements, the PR80 range is used widely with reptiles, birds, and other UV-dependent animals.

What Mercury Vapour Does

Unlike fluorescent UV tubes, mercury vapour lamps produce meaningful heat alongside UVA and UVB, replicating the combined effect of natural sunlight more closely than any single-function bulb. This makes them well suited to basking species that require simultaneous UV exposure and a heat gradient — tortoises, lizards, and turtles in particular respond well to this type of combined output.

Suitable Species and Applications

The PR80 range works across a broad spectrum of setups. Juvenile reptiles, tortoises, and turtles benefit from the combined UV and warmth, while the lower-output options in the range are appropriate even for species with more modest UVB requirements. The full range also serves as a UVA-UVB source for birds and snakes kept in appropriate enclosures.

Positioning and Distances

Mercury vapour lamps require careful positioning. A minimum distance between the face of the bulb and the top of the animal must be observed, with an optimal basking distance typically in the range of 9–12 inches — further still for species with lower UVB requirements such as amphibians. Always consult species-specific care guidance and the manufacturer's recommendations when positioning this lamp.

Choosing the Right Output

The PR80 is available in four wattage options to match enclosures of different scale — lower outputs suit more compact or juvenile setups, while higher outputs are appropriate for larger vivariums where greater heat projection and UV penetration are needed. Select your wattage from the variant options above based on your enclosure size and the requirements of the species you keep.

The Mega Ray PR80 gives reptile keepers a reliable, consolidated light source that handles UV and basking in one fitting — reducing clutter and ensuring animals receive both outputs from a single overhead point, as they would in a naturalistic environment.
