Changing to LED

You have chosen to change to durable and energyfriendly LED lamps, but what do you have to take in account before ordering your new LED lamps? Here you can read the most important things to remember when changing your incandescent- or halogen lamps to LED lamps.

How many watts do you need?

With LED lamps it’s best to check the light output in Lumen in stead of the watts. With LED lamps the watts only tells you something about the power use, not about the light output. For the light output you check the amount of Lumen of the LED lamp.

Here you can find a small chart with examples of how much Lumen a lamp has relative to an incandescent- or halogen lamp. Check the amount of watts you want to replace and choose a LED lamp with the correct amount Lumen.

For example: you want to replace a 40W incandescent lamp, then you have to find a LED lamp with about 400 Lumen to get a similar light output.

Lumen	Wattage incandescent lamp	Wattage halogenlamp
50-100	10W	5-10W
200-300	25W	18-20W
400-500	40-50W	28W
600-800	60-80W	42-52W
1000-2000	100-150W	70-105W
3000-5000	200-300W	230W

Which colour temperature do you need?

LED lamps are available in a large range of colour temperatures. From warm orange light till bright white light. So if you are changing to LED lamps you have to check which colour temperature you want for your new lamps. The lower the number of Kelvin, the warmer the colour temperature of the lamp is. Here you can find more information about the colour temperature of lamps and the number of Kelvin. Till 2700 Kelvin is considered ambient lighting.

2100 - 2300 Kelvin – warm orange light | Flame

2300 - 2500 Kelvin – warm orange/yellow light

2700 Kelvin – warm light | incandescent lamp

2800 – 3000 Kelvin – warm white light | halogenlamp

4000 Kelvin – natural white light

6500 Kelvin – white daylight

Is a dimmer of transformator connected to your lamp?

Check first if the LED lamp you want to order is dimmable – not all LED lamps are dimmable. All dimmers and transformators connected to the lamp need to be replaced by LED types. With LED dimmers you also need to check if you need a trailing edge or leading edge dimmer for the lamps you want to dim. They need to be the same type to make sure the lamp can be dimmed correctly. The wrong combination can cause the LED lamp to flicker or zoom. You also need to make sure the dimmer has the correct wattage for the lamp you want to dim.
