How much light do I get on the power invested?

The real or first question when buying tape is: “How energy-efficient is my tape?”

Will I spend more energy to achieve the desired brightness? The answer to that question is simple. Each LED strip manufacturer defines a characteristic of how much light (lumens) it produces per watt of power (W). These values range from 80 lm/W (for the worst) to even 200 lm/W for the highest quality. Some stripes can consume up to 2.5 times more electricity than the highest quality ones. This size must be declared at the point of sale. The size of the light doesn’t always tell the whole story. Perhaps more illumination is obtained by increasing the number of diodes per meter. The manufacturer may gave more current than declared by LED producer. This will make the LEDs shine brighter, but it will also cause the LEDs to heat up more and therefore reduce their lifespan. So, if the lm/W characteristic is not specified, you can calculate it yourself by dividing the total lumen that the tape emits by the input power.

ESTA LED Strips

ESTA LED strips have till 165 lm/W. The reason is that our products are equipped with OSRAM LED, the most eminent German manufacturer of LE diodes of the highest quality. Thus, some of them (depending of K) belongs even to energy class C.
