Currently, the lighting and the type of market a wide range of mixed quality, consumers in the purchase inevitably Tiao, I do not know the election Which is good. So, how scientific and rational choice of lighting it?
1) The first thing to look for big brands, big brands because of improved regulatory system processes more attention to detail, rigorous operation, and the assembly will be done before the test lamp detection, especially now that the LED lights, if there is no strict regulatory process operation, there will be security risks, produce beyond the normal blue, this blue human eye would cause irreversible damage.
2) is to look at the light color, good lighting suddenly feels light color, light color like that of the sun during the day, gives a comfortable feeling, while the poor lighting fixtures will make consumers feel sight muddy, like chest pressure a block of stone, there is always a sense of oppressed suffocating.
3) See the light-emitting efficiency, brightness is a tile is generated much, i.e., the number of lumens produced per watt higher lumens described luminance, the greater the power consumption at the same brightness produced by the premise, the more energy saving lamps. In addition, there is bad light each lamp, which is used a burst of light levels will reduce human induced attenuation value is 70%, which means that when a new lamp brightness decay to 70% of the time, people can feel ordinary brand of lamps used daily five hours, the light fades in about a year and a half down to 60%, while the big brands of lamps, the use of 5 hours per day in the first 10 years, still have 75% brightness.
Really good energy-saving LED is long life, There are some manufacturers in order to pursue interests in the production of LED lights to cut corners, poor quality products at low prices to induce consumers to use less than two years, the light fades value lamps have can not play down to the normal lighting effects, new lamps need to be replaced, so not only can not be called energy saving, but is energy-intensive products.
