What are lumens and watts?

Led bulbs


In the past, the power of a lamp was expressed in watts. Nowadays you can see that on the packaging of light sources it is usually mentioned lumen. The power of the lamp is the amount of energy consumed by the lamp. Lumen indicates the amount of light emitted by a lamp. In fact, the lumen is a much better way to compare lighting. Lumen is the brightness and indicates how much light a lamp gives, while watts simply indicate the energy consumption of a lamp. The higher the amount of lumen, the more light the lamp gives. For this reason, it is easier nowadays to look at the number of lumens in a lamp and not the power.


Lumen


It is almost impossible to convert powers to lumens because they are two very different units. In the past, you needed a higher power to give a certain amount of light. Now you also have low power lamps that give a lot of light. Because of this, you cannot convert watts to lumens. In general, you can say that a lamp with a higher power also gives more lumen, which means more light.

Existing dimmers often have a minimum power of 50 watts. Because LED lamps have lower power than, for example, halogen lamps, when you only connect LED lights to a dimmer, this minimum power often fails. This may make the dimmer confused and then the lights will flash or overheat. If you tu...

LED lighting lasts a long time LED lighting has a much longer life than traditional lighting. The LED lights are between 15,000 and 50,000 hours. If a lamp is lit for 8 hours a day and 30,000 hours of the fire, it means that your lamp lasts more than 10 years.
