Mercury Vapour Lamps (MVB)
At Internet Reptile we stock a range of Mercury Vapor Bulbs (MVB) for reptiles. These lamps are an all-in-one bulb combining heat UVA and UVB lighting much. These intense lamps replicate the sun by producing hot, bright areas in which you reptiles can bask.
Whilst the concept sounds great, especially when considered alongside the low cost of these bulbs, we would advise their limitations are considered, especially now high output T5 lighting is available. MVB cannot be used with a thermostat, must be hung down vertically (not at an angle) and careful observation is needed when installing to ensure there is ample space between the bulb and your pet. This rules out their use in enclosed areas, such as vivariums or for sensitive species like chameleons.
MVB lamps are very popular for open top tortoise tables where there is plenty of ventilation due to their low cost, you can read more here about the use of MVB lamps vs T5 linear lighting.
