Are there different halogen bulbs?
Halogen lamps include many glass shapes such as Bi-pin, MR, PAR, reflector lamps, double ended, single ended, and A-shaped. The size of a halogen lamp diameter is measured by eights of an inch. MR16 = 2” in diameter and PAR38 = 4.75” in diameter.
How do you fit halogen bulbs?

What are the different types of halogen light bulbs?

Do all halogen light bulbs have the same cap size?
All linear halogen light bulbs have the same cap but come in either 78mm lengths or 117mm length light bulbs. They also come in a variety of wattages, so it is important that a replacement linear halogen is like-for-like (same wattage, same length). See our range of R7s capped lamps here.
