Incandescent bulbs being no longer available for importation into France, manufacturers are quick to put in place the halogen bulbs tell economic. It will replace an incandescent bulb of 60w with an economic 42w halogen bulb either… very few economy actually under light bulbs led.
Knowing that we only use halogen bulbs in some lamps and ceiling spots, we still have to determine what kind of bulb we choose, GU10 230v or Mr16 (also called GU5.3) in low voltage.
How to replace a light bulb by a led gu10 light bulb gu10?
The bulb gu10 base is one that is used more and more often, she works on 230v and sometimes is dimmable. She was generally reserved for the ceiling spots but setting it up is easy and the socket being much more secure than on the other units in 230v, we then eventually found in many applications.
There so now gu10 bulbs in bathroom appliques, in bedside lamps or in office, in external or internal projectors lamps “Par16 gu10” format but also in floor built-in lights. There are even some liens web adapters for switching from a nerve (nerve large screw) E27 a gu10 base. Replace these bulbs gu10 led bulbs by represents therefore a certain interest in what concerns the power consumption but as we use them everywhere just to keep one as a backup in order to place it at the place where your halogen bulb to let go.
The replacement is performed on equal terms, to say that simply replace your halogen by an led gu10 bulb, all without forgetting to turn off the power before any manipulation. However make sure you do not use inverter if the led light is not dimmable or direct you to a dimmable bulb if your installation is provided with a dimmer however test to the faster because all inverters, designed originally for halogen, are not necessarily compatible with low consumption led bulbs.
As this bulb offers excellent support by its characteristic socket since it is sufficient to make a quarter turn with the bulb so that it hangs in its socket, bulb – leds.fr produces and sells also liens web a model in low voltage gu10 led bulb mainly for our motorhome guests.
How to replace a light bulb Mr16 / GU5.3 by a led Mr16 bulb / GU5.3?
Also called GU5.3 Mr16 bulb is easily recognizable thanks to its equipped nerve to 2 points, it is reserved for applications that require some security and thus a low voltage, and is sometimes also dimmable. It was generally used in the ceiling spots around our homes because these halogen bulbs very low voltage have a better light output (lm/W) than bulbs operating at mains voltage. The filament longer runs and most important section, so he could be brought higher in temperature however this induces a concern sometimes for size because each bulb was equipped with a transformer to lower the voltage of 230v section at only 12v. Not only, each transformer consumed him even of the common, but in addition for some construction it is sometimes impossible to locate processors in our ceilings…
We find so now Mr16 bulbs in more and more applications such lamps bureau, in some outdoor lighting or recessed lighting of ground usually near the pools and of course on wires suspended and ceiling spots. Replace these halogen bulbs very energy efficient, because as I said to the consumption of the bulb must be added that of the transformer (sometimes known as a converter), represents an interest even higher in terms of power consumption.
Mr16 halogen bulbs replacement is not as simple as for gu10 bulbs because to power a 12v halogen bulb we must go through a transformer current alternative (AC). What does a transformer for halogen lamps?
A transformer is limited simply to lower the voltage of 230v to about 12v however it does not change its frequency (from 50 Hz in France) or two-way direction of the current flowing in the 2 so feel (alternating current). He is there to so no polarity current alternative and the final voltage depends on the input voltage which induces a 5v tolerance in general or a range of operating voltage of 11.6v to 17v for an AC voltage to 12v AC.
Our concern lies in the fact that by nature, a LED is fed current continuous, therefore with an led bulb low voltage Mr16 we use a food and not a real transformer for halogen lamps. What is a diet?
A diet will lower the current, straighten it out and convert current DC (DC). The current circulates more than one way, the positive terminal (+) to the negative (-) and it is also much better stabilized with a much lower tolerance of the order of 0.2v on average. Own consumption is almost zero for small powers consumed but DC does not permit the carriage of the current over long distances it is little used. Nevertheless it is precisely what requires an led bulb low voltage to work perfectly.
The tolerance of the led is much lower than that of a filament, it is not possible to use a halogen transformer to power the led bulbs under penalty of very rapid destruction of components of the led bulb low voltage.
We offer liens web a range of power supplies for led light bulbs low-voltage (called “Transformers” for the ordinary people since in popular parlance we call a transformer anything that reduces the voltage) that you must use low voltage with led bulbs. Therefore entails additional costs because more of the bulb you must also replace your halogen transformer and for this reason it is advisable to replace these bulbs low voltage Mr16 bulbs gu10 230v everywhere or it is possible. Attention, in some places to a dwelling standards impose a mandatory lighting low voltage (proximity to the points of water, proximity pool, ground application, application on suspended cables or metal conductor rail of power, some places in the bathroom, etc…).
