Mega-Ray Mercury Vapor Bulb, 275w

The Mega-Ray Mercury Vapor Bulb, 275w, offers a powerful combination of heat, light, and UVB, essential for your reptile's health. Renowned as one of the most dependable mercury vapor bulbs in the US, this product stands out for its durability and performance.

With advanced technology and over two decades of in-depth research, Mega-Ray has dramatically minimized the degradation rates common in other mercury vapor lamps. Unlike competitors whose bulbs may lose up to 80% of their effectiveness, the Mega-Ray bulb retains over 70% of its potency throughout its lifespan.

This 275w bulb is a self-ballasted PAR-38 True Frosted Flood Lamp, designed to provide a broad spread of usable UVB across a 30" diameter when placed at a 20" height.

For optimal results, replace the Mega-Ray Mercury Vapor Bulb every 18 months to ensure consistent performance.

Minimum Distance: 34"

Maximum Distance: 46"

Usage Guidelines:

We highly advise pairing this bulb with a Solarmeter 6.5 to monitor UVB levels and ensure your reptile receives the correct exposure.

Always use a wire lamp fixture rated for at least 275w to avoid overheating risks.

Given its intense UVB output, this bulb is ideal for spacious enclosures (minimum 48" in height). Be sure to understand your reptile’s specific UVB needs and adjust the bulb-to-basking area distance as necessary.

You might need an extra halogen heat source or UVB bulb to achieve the right temperature or UVB gradient for your pet. Regularly check the basking spot temperature and adjust the fixture height to maintain a safe heat range. Always double-check basking area temperatures to prevent any risk of burns to your reptile!
