White Light Bulbs – After seeing what LED lighting is and the types of LED bulbs we can find it is good to also know how to choose the right one according to usage or need. For this, we have to take into account different aspects like the power in real lumens, the angle of opening, the temperature of the light and the installation that we have at home. A lumen is a unit used to express the amount of light that is capable of generating a light bulb. The problem is that the lack of union by the manufacturers does not allow unifying criteria so we can have some other problem. Anyway, the theory tells us that a led is capable of generating by it between 60 and 90 lumens.
Any value above or is false or low very optimum circumstances. Being 70 a mean value that matches most bulbs on the market. Therefore, 12W white light bulbs would provide a light output of 840 lm. That would replace the light that generates a 60W incandescent bulb. As you can see generating the same amount of light we saved 48w for each incandescent light bulb we replaced. If we buy LED bulbs whose opening angle is 40º we will get a more focused light that would be ideal to illuminate concrete points like a painting, showcase, etc. Therefore, for a room we have to acquire a bulb with 120 degrees of opening that is suitable for rooms.

When we go to buy white light bulbs we can check the temperature in degrees Kelvin to know what kind of light will give. If it is environments at 3.000K will be a warm white, 4500K is pure white and 5800K cold white. Each one will decide what type of light he likes best according to the room where he will use it. Not everyone has the same installation of lights at home. Some use incandescent bulbs, other fluorescent lamps or halogen lamps.More reader came from this term: how to choose light bulbs, pure white light bulbs, types of lighting bulbs
