LED spotlight 12V (GU5.3)

Low-Voltage LED Spotlight 12V with Pin-Base GU5.3

These are alongside the familiar light bulb the biggest "electricity guzzlers".
The level of efficiency (luminous efficacy rating) is not noticeably better than
of the light bulb. It is just the MR16 design which is still in use as halogen
lamps and could be exchanged without compromising immediately against
LED spots. The energy saving is about 80%.

GU5.3 is called the 12V socket variant for the design of MR16 spots. These are built-in spots, now in LED version, with 50mm diameter and the base shown here consisting of two thin pins. The LED spotlight is plugged into the 12V socket by simply pressing it.

This low-voltage version (12V) already contains a constant current source in a small housing. However, an additional LED transformer is required to convert the 230V to 12V.

Low-Voltage LED Spotlight 12V with Pin-Base GU5.3

In compare 12V halogen to incandescent and LED spotlight 12V (GU10/5.3)

Lamp type	Luminous efficiency	Lifetime
Light bulb	10 lm/W	ca. 1000 h
Halogen lamp	15 - 25 lm/W	ca. 2000 h
LED light	60 - 100 lm/W	ca. 25000 h

This table above clearly shows that an exchange of halogen to LED makes perfect sense. Even at low
burn durations, payback occurs within one year of implementation.

For use in hotels having high burning times the costs are usually saved after 2-3 months.

The Socket Type GU5.3

The so-called low-voltage lamps have lead pins type GU5.3 and are simply plugged into the socket. The
pin distance of have just 5.3mm. The operation is possible with 12V AC or DC, which consists of a LED transformer.
It should be ensured that the minimum load is not exceeded by energy-saving LEDON spots. Often is
a replacement of old transformers with modern LED transformers needed.

The topic with dimming by LEDON Spots MR16 (GU10 or GU5.3)

While halogen bulbs could be dimmed easily, it is only possible with LEDON spots and other LED lamps,
which are explicit marked accordingly as "dimmable". With low voltage you also have to be careful, that
the transformer is also dimmable. If you ignore it, so there may be flickering at LED spots and both of them
could be destroyed.

Most application of LED Spot 12V with GU5.3:

Hotels, restaurants, offices and meeting rooms. Actually everywhere where previously MR16 halogen lamps
are used. Exchange it now!
