Q:How does LED ceiling light distinguish between good and bad?
You can ask the merchants and questions to resolve them!First, is it possible to guarantee two to 3 years?Second, the annual depreciation is within 5%Third, is the color rendering index above 85?Fourth, whether it is SMD beadsFifth, the light efficiency can achieve 90 lumens per watt?Sixth, is the luminous angle 180 degrees?Seventh, the most direct way, good ceiling lamp, basically 10 yuan per watt
Q:15 square meters of living with the Duodawa number LED ceiling lamps
Larger space needs to be increased by other auxiliary light sources, and it is not suitable to use a single main light, then the wattage of main light can be reduced.The wattage of the light bulb may not be in line with the calculated value, but the actual selection results may vary by 15%Consider the selection principle of lamps and lanterns economically:1, large space should not use LED, LED lights now about 2.1 yuan /w, but the same illuminance, energy-saving fluorescent lamp less than half.2, frequent opening and closing of the lights, energy-saving lamps should not use, you can choose incandescent lamps, such as corridors3, the table lamp as far as possible (read) as far as possible not to use energy-saving fluorescent lamp, hurt eyes4, closed narrow lamps, as far as possible without LED lights, heat is not good, aging fast5, LED lights, try not to direct eyes, dazzling. Can be placed aloft, such as ceiling lamps, or in a lampshade.
Q:Introduction to the working principle of LED ceiling lamp ballast
