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 ligh 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 85%.
GU10 is the 230V socket variant of the MR16 design. This GU10 spot with 50mm diameter has a base with two thick pins that are "screwed" by pressing and turning into the socket.
This high-voltage LED spotlight 230V includes an integrated LED driver and works more efficiently than the "little brother" with GU5.3 socket, since no additional transformer must be connected in front.

|Lamp type||Luminous efficiency||Lifetime|
|Light bulb||10 lm/W||ca. 1000 h|
|Halogen lamp||15 - 25 lm/W||ca. 2000 h|
|LED spot 230V||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.
While halogen bulbs could be dimmed easily, it is only possible with LED spots and other LED lamps,
which are explicit marked accordingly as "dimmable". With low voltage care must be taken to ensure if the
transformer is also dimmable. If you ignore it, so there may be flickering at LED spots and both of them
could be destroyed.
While MR16 describes the design with a diameter of 50mm, these differ even in the connector base
and thereby also in the operating voltage. For direct connection to 230V, the base type GU10 is used (see. GU5.3) This socket follows the bayonet principle. The e. g. LED spot MR16 type GU10 is pressed into the socket and turned afterwards. An exchange is usually not a problem. GU10 is recognizable by 10mm contact distance.
Hotels, restaurants, offices and meeting rooms. Actually everywhere where previously MR16 halogen lamps
are used. There is no more reason to wait for.
