Heat, light, and high-intensity UV—all powered by a single, self-ballasted lamp. The Reptile Systems Mercury Vapor UV Basking Lamp is the ultimate all-in-one lighting solution engineered specifically for large enclosures and high-UV demanding reptiles.

Favored by zoos, breeders, and keepers alike, this powerful lamp eliminates the need for multiple bulky fixtures. It features a wide 35-degree beam angle to establish a generous, cozy basking zone that mimics the natural properties of the sun. Providing an intense balance of UVA, UVB, visible light, and infrared (heat) energy, it effectively aids vitamin D₃ synthesis and proper calcium absorption—keeping your animals structurally vibrant and completely safe from Metabolic Bone Disease (MBD).

Why Choose the Reptile Systems Mercury Vapor Lamp?

• Self-Ballasted Convenience: No external ballasts or complicated hardware needed! It features a built-in starter unit that plugs directly into a standard ceramic fixture.
• Industry-Leading UVI Output: Engineered for superior efficiency. The 80W bulb matches the output of most competitor 100W bulbs, while the 100W bulb rivals standard 160W competitors. The top-tier "160" model delivers maximum power using only 125 watts of actual energy.
• Triple Batch-Tested Quality: To ensure absolute animal safety, every single batch is rigidly tested for UVI parameters three separate times across facilities in Germany, France, and the UK before it ever hits the shelf.
• Long-Lasting Performance: Boasts an average lifespan of 6,000 hours and continues to project excellent UVI levels even after a full year of normal use.
• Peace of Mind: Backed by a 6-month manufacturer guarantee and includes a detailed instruction sheet.

Important Safety & Installation Notes

• Vertical Mounting Only: To protect the delicate internal filaments, this lamp must be installed pointing completely straight down (vertically). Mounting it horizontally or at an angle will heavily degrade the lifespan and void the warranty.
• Thermostat Note: Mercury vapor lamps cannot be run on a thermostat. However, they can be easily automated using a standard on/off light timer.
• Built-In Thermal Cutoff: The lamp features an advanced safety switch to protect against voltage spikes and overheating. If turned off or interrupted by a power flicker, it will not turn back on immediately. Allow the lamp to cool down for approximately 20 minutes before restarting.
• Fixture Requirement: Due to the extreme heat generated, always use this bulb in a high-quality, heat-resistant ceramic (porcelain) socket.
