Frequently bought together:


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:

  • 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

    Please don’t ignore this or brush this review off. It is truthful and I am hoping it will save you from making the same mistake as I. This September I bought my first ever Hermanns Tortoise hatchling as I have always wanted one! I did my research and purchased all of the equipment that I deemed appropriate for keeping my baby tort healthy, stimulated and alive! One lighting option I came across was a Mercury Vapour Bulb - a seemingly perfect solution for a first time tortoise owner, like myself. When browsing for one, I found the Internet Reptile bulbs. It was the summer sale and their offer was 2 for 1. I decided to go for it and ordered some other things from them as well. After less than 2 weeks, the first one went. Already not happy, then I changed it for the spare. That one also went, but this time it blew after less than 2 hours! PLEASE DO NOT BUY. Thankfully they offered free returns for the bulbs, and 100% refund. Please help out your reptile by buying a reputable brand’s bulb such as Arcadia! Thank you :)
