GU5.3 MR16 light sources are low-voltage light sources with a pin spacing of 5.33 mm. MR16 describes the diameter of the reflector: 16/8 inch.
A less common version is GU5.3 MR11. For this reason, the base and reflector size should always be taken into account when replacing the bulb. A further note: There are also G53 lamps (without dot and U) - but these are significantly larger and are operated with 230 volts.
GU5.3 MR16 light sources are all standardized, which means they can also be easily replaced by LEDs.
GU5.3 MR16 lamps provide directional light thanks to the reflector, which is mostly used in spotlights and recessed luminaires.
The most common area of application for GU5.3 MR16 lamps are spotlights and spotlights, where the light source is shown to its best advantage thanks to the reflector. The lamp can be found in cable systems, single and multi-flame surface-mounted ceiling luminaires and above all in recessed luminaires.
However, perhaps the best-known luminaire with a GU5.3 MR16 socket is the One From The Heart table lamp by Ingo Maurer, which the world-famous designer originally created as a wedding gift.
Many low-voltage cable systems use GU5.3 MR16 reflector lamps.
World-famous: the One From The Heart luminaire by Ingo Maurer.
GU5.3 MR16 lamps are also available with modern LED technology. Changing the lighting technology has no influence on compatibility, the pin spacing and the reflector size. GU5.3 MR16 LED lamps are therefore only an improvement compared to conventional halogen lamps. LEDs:
Since GU5.3 MR16 light sources are rarely used alone, but rather in groups in recessed spotlights or cable systems, it is particularly worthwhile converting to LED.
The difference lies in the pin spacing (GU4 pins have a spacing of 4 mm) and usually also in the reflector size, indicated by the following MR.
Both light sources are low-voltage light sources, but the smaller GU4 lamps are used more in recessed furniture lights, under-cabinet lights or extractor hoods, for example.
