Mega Ray 100w Mercury Vapour UV Bulb E27 PAR38 Reptile Lamp

The Mega Ray 100w Mercury Vapour E27 PAR38 is a combined UVA, UVB, and heat source in a single bulb, designed for reptile and exotic animal keepers who want a proven, professional-grade lamp without the complexity of a multi-unit setup. The PAR38 form factor keeps things compact, making this a practical choice for keepers working with smaller enclosures or younger animals that benefit from a less intense output than larger mercury vapour lamps.

Compact Build, Serious Output

Despite its modest dimensions — just 3 inches wide and 4.5 inches long — this bulb delivers the same quality UVA and UVB emission that the Mega Ray range is built on. It is not a beginner's shortcut; it requires the same considered placement and setup as any professional mercury vapour lamp.

Correct Positioning Matters

A minimum distance of 6 inches from the face of the bulb to the animal must be maintained at all times. For most reptiles, an optimal working distance of 9 to 12 inches is recommended. Species with lower UVB requirements — including amphibians — should be kept at even greater distances to avoid overexposure.

Species Suitability

• Well-suited to juvenile turtles, tortoises, and lizards requiring combined heat and UV
• Functions as a UVA and UVB source for birds (avian setups)
• Suitable as a UVA-UVB lamp for snakes
• Appropriate for smaller vivarium or terrarium setups where a lower heat output is beneficial

With its E27 fitting and PAR38 profile, the Mega Ray 100w integrates cleanly into standard lamp holders and gives keepers a reliable, all-in-one lighting solution they can trust across a range of species and enclosure types.
