At the time of the incandescent lights was very simple choose that would handle larger lighting: what would emit the largest amount of watts (W) was the one who lit up better.
Today, fortunately, is no longer so. The LED technology uses the concept of luminous flux or lumen (Lm), which is the unit of measurement of light emitted by a particular lamp. In this way, what matters now is not simply the amount of watts and the amount of lumens emitted for every watt consumed (Lm/W).
What is the equivalence of light bulbs?
Taking into account the previous explanation, we can compare the different equivalences between the existing lamp types. A 20W incandescent bulb equivalent to a 2W LED, with issuance of 50-80 lumens.
Already for fluorescent lamps, if we take as an example a 12W, will be equivalent to a LED 6W, with issuance of 390-550 lumens and a 50W of incandescence. That is, the LED lamps represent visibly a energy saving in relation to the other.
When buying a LED bulb, so don’t just check how much power. Consumers need to be aware of the luminous flux indicated on the back of the Pack to compare with competitors. Without this information, the item shouldn’t even leave off the shelf because it is required by the Brazilian labeling Program (PBE).

In times of energy crisis, it’s easy to see how the LED lamps are able to save, making them a benefit to the environment. In addition, they are durable and can reach over 17 years of use if considered a use of 8 hours per day.

The LED, and a boot right away, do not cause as much damage to the environment and may also be used in environments with no vegetation that represents any kind of risk.
They are actually more expensive than the fluorescents, but if we consider the durability, economy and the low maintenance cost, end up representing an excellent cost-benefit ratio in the medium and long term.
