Mega Ray 70w Mercury Vapour Bulb E27 PR80 | UVA UVB Reptile

The Mega Ray 70w Mercury Vapour E27 (PR80) is a compact self-ballasted UVA/UVB lamp designed for reptile and avian keepers who need a reliable combined heat and UV source in a smaller vivarium setup. At 70 watts, it suits enclosures where the larger mercury vapour lamps would be excessive, making it a practical choice for juvenile tortoises, turtles, lizards, and snakes, as well as birds requiring a quality UVA/UVB source.

Compact dimensions, serious output

Despite its small footprint — measuring approximately 3 inches wide and 4.5 inches long — this bulb delivers the same quality UV output that the Mega Ray range is known for. Do not let the size mislead you: it carries the same handling and placement requirements as any professional mercury vapour lamp and should be treated accordingly.

Correct positioning matters

A minimum distance of 6 inches must be maintained between the face of the bulb and the top of the animal at all times. The optimal basking distance sits between 9 and 12 inches for most species. For animals with lower UVB requirements, such as amphibians, an even greater distance is recommended to avoid overexposure.

Species suitability

• Juvenile tortoises and turtles — strong UV output supports D3 synthesis and healthy shell development
• Lizards requiring moderate to high UVB levels
• Snakes and avian species benefiting from UVA/UVB exposure
• Low-UVB species such as amphibians, used at increased distance

The Mega Ray 70w E27 PR80 gives keepers a single-lamp solution for both heat and UV in a format that works where larger bulbs simply cannot. Fit it correctly, respect the minimum distances, and it will deliver consistent, quality output for your animals.
