What’s а Lumen?
Lumens measure the total number of packets of light produced by а light source, which is а complicated way of saying how much light а source puts out. We have become accustomed to measuring light by watts. The average incandescent bulbs only put out abut 12 lumens for every watt of electricity they consume. In contrast, LED bulbs produce about 60-100 lumens per watt.
Knowing the approximate number of lumens for which to search will help you avoid taking home the wrong bulbs. For example, when purchasing bulbs to replace those in а chandelier that uses 25 watt bulbs, which coincidentally produce about 250 lumens, you would not want to get 0.5w LED bulb just because the shape is right – that bulb only generates 4 lumens.
The lumen of the LED Bulb is the most important factor to measure whether it is the right level for your need. Pay more attention to this factor and you will be easier to get the one that right for you. If you still do not understand the lumen, you can ask the stop owner when purchasing. You can offer the square of your room, such as 40 m2 or 80 m2 and they will tell you what lumen of LED bulb is suitable for you.
