Mega-Ray Mercury Vapor Bulb, 160w

The Mega-Ray Mercury Vapor Bulb, 160w, is an all-in-one solution that delivers heat, light, and UVB radiation essential for your reptile's health. Renowned as one of the most dependable mercury vapor bulbs in the US, it stands out for its superior quality.

With over 25 years of innovative research and advanced technology, Mega-Ray has drastically minimized the degradation rates common in other mercury vapor lamps. Unlike competitors that lose up to 80% of their effectiveness, this bulb retains over 70% of its potency throughout its lifespan.

This 160w bulb is a self-ballasted PAR-38 True Frosted Flood Lamp, designed to provide a wide spread of usable UVB across a 30" diameter when placed at a 20" height.

For optimal performance, it’s advised to replace the Mega-Ray Mercury Vapor Bulb every 18 months.

Minimum Distance: 18"

Maximum Distance: 24"

Usage Guidelines:

We highly recommend pairing this bulb with a Solarmeter 6.5 to ensure your reptile receives the appropriate UVB levels.

Prevent overheating by using this bulb with a wire lamp fixture.

Given its intense UVB output, this bulb is ideal for spacious enclosures (at least 30" in height). Make sure to understand your reptile’s specific UVB needs and adjust the bulb’s distance from the basking spot as needed.

You might need an extra halogen heat bulb or UVB source to achieve the ideal temperature or UVB gradient for your pet. Always monitor the basking area temperature closely and adjust the fixture height to create a safe heat gradient. Double-check basking spot temperatures to avoid any risk of burns to your reptile!
