LED Instead Of Halogen-What Do I Have To Consider?

Do you want to have LED instead of halogen? You want to replace the inefficient and cost-intensive halogen spotlights against energy-efficient and environmentally-friendly LED spots, thus reducing the electricity bill? No problem! We explain what you need to consider. Using the example of Osram GU5.3 LED spots , we go through the most important steps when buying a new LED spotlight.

LED Instead Of Halogen: Which Socket?

First of all, you should know what version the old halogen spotlight has, according to elaineqho. For halogen there are the sizes GU10, GU5.3 and GU4. The name of the version depends on the millimeter spacing between the two pins. If we have an old halogen lamp of the GU5.3 version, this must also be replaced by a LED spot with the GU5.3 socket.

LED Instead Of Halogen: What Number Of Watts?

The wat number, on the other hand, does not have to be the same for the LED instead of halogen, since the latter would be reduced by using the energy-saving LEDs. The GU5.3 spot LED has a power of 6.8 watts and a halogen spot of 35 watts. The LED spot thus consumes 28.2 watts less than the halogen variant.

LED Instead Of Halogen: Light Color And Brightness

When exchanging LED with halogen, the Watts number is not a primary indicator for the same brightness. The brightness of an LED spot can be seen in the value lumen. Our GU5.3 LED Spot has 350 lumens, which is approximately the same as the brightness of an old 35 watt halogen bulb.Furthermore, you should pay attention to the light color of the new LED Spot. The usual light colors are warm white and daylight. The light color in Kelvin is measured. The light color of warm white corresponds to 2500 to 3000 Kelvin, the color of daylight from 4000 to 7000 Kelvin. Especially the warm white LED spots correspond to the light of the old halogen spots. The LED Spot GU5.3 from Osram has a light color of 2700K (warm white).

LED Instead Of Halogen: The Right Beam Angle

As a rule, the old halogen spots had a radiation angle of 30 ° -36 °. In the LEDs, however, there is now a whole range of different radiation angles, which in part illuminate more, sometimes less area than the old halogen spotlights.  If you now want to use LEDs instead of halogen, you should also pay attention to the correct beam angle.The GU5.3 LED Spot from Osram, for example, has a beam angle of 36 ° and thus exactly corresponds to the halogen model.

LED Instead Of Halogen: Problems With Replacement Due To Transformer?

In ¾ of the cases, there is no need to pay attention to halogen when replacing LEDs. It can be problematic if a low-voltage halogen lamp (with an operating voltage below 50V), such as a GU5.3 or a GU4, is to be exchanged for an LED and has an upstream transformer which does not correspond to the latest prior art. This is particularly problematic because a 12V transformer must have a minimum operating voltage. How exactly you convert from halogen to LED in such cases can be found here.

LED Instead Of Halogen: Find The Right LED Spot

The product names of the LED spots are partly composed of the abbreviations explained above. Let us take the example of our LED Spots GU5.3 from Osram.The complete product name is Osram LED STAR MR16 35 (36 °) GU5.3 LED Spot 6.8W.

Osram : Product name
LED : Lighting technology
MR16 : Describes the type of housing, MR stands for “multifaceted reflector”, there is also the abbreviation PAR “parabolic aluminized reflector”, the 16 stands for the spot diameter in eighth inch (1 inch = 2.54 Cm)
35 : Analogue Watts old halogen
(36 °) : Beam angle
GU5.3 : Socket
LED spot : Type of illumination
6.8W : Wat number of the LED
