  • Important for reptiles development and health.
  • Aids the synthesis of Vitamin D3​.
  • Helps prevent metabolic bone disease.​
  • Use alongside T5 tube lamps to generate a natural photo-gradient.

  • Designed as a basking lamp for larger vivaria in which the reptile has sufficient room to move away to regulate its temperature.

The Mega-Ray mercury vapour bulb is their top-of-the-range 160 watt Self Ballasted Par-38 Narrow Flood Lamp which has been shown in tests to produce similar amounts of UVB to natural sunlight! Along with adequate heat, the bulb creates the optimum basking spot at the recommended distances, in most circumstances. Additional lighting and heating should be considered if necessary, particularly in larger enclosures. This large bulb promotes the synthesis of Vitamin D3 and prevents metabolic bone disease, and because of the very high levels of UVA, stimulates the emotional well being and activity.

This Mega-Ray is their original design, it is the only bulb on the market to use a translucent magnesium oxide inner coating, which helps provide the necessary visible light, UVB, UVA and heat for basking reptiles. For 10 years, it has been shown to have the longest lasting UVB production of any other mercury vapour bulbs available, frequently lasting over 6000 hours, that is 500 days (based on a 12 hour day)!

Mercury vapour bulbs are exactly what they sound like, glass bulbs filled with mercury vapour which project a full spectrum light. Mercury Vapour bulbs are safe when they are kept intact, given sufficient room and hung in a vertical position. the vertical position allows convection currents to circulate within the bulb, prolonging its lifespan.

Mercury Vapour Bulbs cannot be used with a thermostat or external ballast and therefore should only be used in large enclosures, or open-top tables. A dimming thermostat increases and decreases the output to the bulb as required; Mercury Vapour Bulbs must run at a specific output in order to produce UVB, if this is dimmed by a thermostat they can still produce heat and visible light (UVA) however they will not produce the vital UVB light your animal needs, and turn it into a very expensive simple basking spotlamp! It will also shorten the bulbs lifespan drastically.

Due to their high wattage an inability to be thermostatically controlled; these bulbs should only be used in large vivariums or open top table enclosures. Although not strictly necessary for most species it is recommended to install a secondary source of UVB light, such as a T5 tube bulb or a compact lamp. This gives your animal the option to bask under UVB light without also experiencing hot temperatures.
