How to Calculate LED Power Supply

You want to move to LED, but do not know the equivalence in terms of power? This article will answer all your questions!

How to Calculate LED Power Supply

Watt, Lumen: some definitions to begin

Watt (W): Watt is the unit of measurement of power bulbs ‘classic’. It expresses in fact its electric power consumption. There is also mention of Watts on LED bulbs and find that they are much less energy. But this is not the Watt to measure the light intensity of a light bulb. The terms “power” and “brightness” are often confused, which is why we take stock today.

The lumen (lm) Lumen is the unit of measurement of light intensity. This is surely to it than you think when you talk about “power” of your LED spotlight with E27 light bulbs. The more Lumens, plus the flow of light is important.

Luminous efficiency: for although you realize the advantage of LED bulbs vis-à-vis conventional bulbs, compare their light output. Light output expresses the luminous intensity per Watt spent.

Use the Lumen for comparing the light intensity

If Watts were previously used to measure the power of conventional light bulbs, use for LEDs for equal power in terms of watts, LED bulbs illuminate more than conventional bulbs.

If you want to make a quick conversion of Watts Lumens for comparison, multiply Watts by 10 to get the Lumens. So if your old bulb has a consumption of 30 W, you need an LED bulb of 300 lumens to get the same luminous intensity. To help you on the site, we have indicated the equivalence in the product description.
