View all Low voltage

Low voltage spot bulbs have a 2 pin push in connector. The pins are often quite sharp and do not have 'feet' at the end of each pin.

There are various types of low voltage spot bulbs. They are often called MR16, MR11 or MR8. These names refer to the diameter of the front of the lamp, in 8ths of an inch. MR means 'multifaceted reflector'.

Sometimes the different bulbs are referred to by the distance between the center of the electrical pins. GU5.3, or GU4 are the common sizes, which are 5.3mm and 4mm apart.

MR16 Bulbs

MR16 bulbs have a diameter of 50mm or 16 x 8ths of an inch. They are commonly used in recessed downlights, track lighting and other decorative fittings.

Sometimes they are referred to as GU5.3 bulbs as the center of the two pins are 5.3mm apart.

MR11 Bulbs

MR11 bulbs have a diameter of 35mm, or 11 x 8ths of an inch. They are popular in small spot light fittings, track lighting, and some modern cooker hoods. They are available in a variety of voltages and wattages.

The 12w version of these lamps are the most common. The open-fronted version is often used in fibre optic Christmas decorations.

Sometimes MR11 bulbs are referred to as GU4 spot bulbs because the center of the two pins are 4mm apart.

MR8 Bulbs

MR8 bulbs have a diameter of 25mm, or 8 x 8ths an an inch. They are not very common as they are so small. They are used in a wide variety of applications requiring a small source of light.

Sometimes MR8 bulbs are referred to as small GU4 spot bulbs because the center of the two pins are 4mm apart.
