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.

Now available in 4 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)
  • *NEW for 2023* 125w - for when you need a little more heat or distance
  • 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:

  • Install at a safe distance, in a quality heat resistant (ceramic) fitting or clamp lamp (min diameter 20cm)

  • 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

Excellent bulb

Arrived super quick and well packaged. Tortoise quote content basking under its warmth. Nice glow too.

An amazing bulb (internet reptile mercury vapour bulb)

I bought these to replace the expensive brand as mega ray which the bulbs of late were really faulty and not working after two weeks even the replacements but the old spares continued to work that we had from mega ray so the new batches mustn’t be up to standard anymore.

However this little gem from internet reptiles works amazingly well and our tortoise loves it, we bought a couple of these because the price and quality is great.

Would highly recommend this product
Thanks internet reptile!
