The Internet Reptile Mercury Vapour Bulb (MVB) is an "all in one" lamp providing infra-red (Heat), UVA (Visible Light) and UVB from a single bulb.

This type of lamp cannot be used with a thermostat, so is commonly used in open topped tortoise tables or other well ventilated enclosures which help to avoid heat build-up.

Available in 3 wattages; the following information is a guide to help you choose the correct bulb and safe installation distance from your pet.  

In warmer areas and in summer months, it can be used in isolation to create a warm basking area. In cooler areas, or for a wider beam of visual light, can be used in conjunction with a regular flood or halogen lamp controlled by a dimming thermostat. Alternatively, installation in a 'dome' type fitting can help to increase temperatures at the warmest part of the enclosure.

Aim to create a range of bright and shaded areas with different temperature and UV levels within the enclosure; this will allow your pets to correctly thermoregulate by choosing when and where they bask.

Installation and Warranty:

  • Use in a large fitting to ensure plenty of airflow (we recommend a 200w / 20cm + fitting if using a dome)
  • Install at a safe distance, in a quality heat resistant (ceramic) fitting or clamp lamp

  • Position vertically (hanging downwards), not at an angle

  • Not suitable for use with a thermostat

  • Protect against knocks or accidental contact when in use

  • Protect against accidental contact with water

  • Always allow the bulb to fully cool before moving or repositioning.

  • Six month warranty from date of purchase (allows for an identical replacement lamp where the above has been adhered to)

  • Approximate usage time of 6000 hours

  • For reptile use only

    So I’m new to the whole reptile pet thing, and it can be expensive setting up from scratch. But buying from here was easily and quick. As for the item, great value for money, delivery came really quick, and well packaged

    My tortoise loves the bulb. All in one so means only having to have one bulb. We have now got a thermostat which tells me the bulb gives the exact temperature the tortoise needs. Will be using this bulb forever. Good price too.
