“Lumens” is a term that is often when it comes to lighting. But what did the lumen, exactly? And how do you know how much you need to well to illuminate your space? Here are the most important facts about the lumens and how to apply it to the lighting in your home.
Lumens equal to the brightness
The notion of lumen describes the amount of light produced by the bulb. More lumens means more lights. The power, which is sometimes confused
as a measure of brightness, is actually a measure of power consumption. A 100-watt incandescent bulb is equivalent to approximately 1600 lumens, while a 40-watt incandescent bulb is equivalent to 450 lumens.
Choose the right bulb
Light output will be indicated on the packaging of the bulb, it is incandescent, LED or CFL (compact fluorescent lamp). Here you will also find the color of the light, or the light temperature. If the luminaire uses a LED or a built-in LED module, lumens should be listed on the data sheet of the manufacturer.
How many lights do I need?
The room type will determine lighting requirements and the needs of lights. For example, a bathroom or a kitchen will require more light than a living room or a bedroom. To determine roughly how much light is necessary for your space, to determine the area of the room. To find this, multiply the length by the width of the room. If your room is 4 m x 2.5 m, it is 100 meter square. Then, determine the power required to illuminate the space. Take the surface and multiply by 15. The result will give you the amount of power needed for general illumination. So, the 10 square meters room will need about 150 watts for general illumination, which equals approximately 2250 lumens (at the base of output of incandescent lamps).
How do lumens compare with watts?
The efficiency of transformation of energy to the brightness is measured by the light output. This means, how many lumens a watt of power can generate. Normally, for an incandescent bulb, the light output is limited to between 10 and 16 lumens per watt; but for the CFL or LED bulbs, that adds up to between 70 and 95 lumens per watt. As a result, have CFL or LED lamps is more economical in the long term that have incandescent lamps
Now, you have perhaps understood the importance of the index of lumen and are ready to choose lamps that meet the best your illumination needs. You are invited to visit our store you with pleasant and functional models.
