GU5.3

The GU5.3 cap is the connector for one of the most popular bulbs on earth: the MR16 low-voltage spotlight. The lamps are almost always halogen or LED, and in constant demand for their wide variety of designs and beam angles. Halogen MR16 reflectors are typically dichroic, thus dissipating IR heat through the back of the lamp. The mains-powered version of the MR16 is the GU10, named after its base.

Alternative names:

None.

Bulb types:

MR16 reflector.
