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.
Installation and Warranty:
- Use in a large fitting to ensure plenty of airflow (we recommend a 200w / 20cm + fitting if using a dome)
