Mercury Vapour Bulb (MVB) 100w

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.  

• 80w (lamp to animal distance approx 25-35cm)
• 100w (lamp to animal distance approx 35-45cm)
• 160w High Output (lamp to animal distance approx 60-75cm)

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.
