How to buy rest assured LED lighting products

　　LED lamps are energy-saving effect is obvious , long life, no radiation, no stroboscopic effect , no noise , light and soft, wide operating voltage range of features , such as a series of increasingly welcomed by consumers . As a consumer, how to choose a shop in a dazzling array of LED lighting fixtures in their satisfaction with the products?

　　First, the packaging and trademarks. National mandatory LED lighting manufacturer marked on the product packaging the following : Rated voltage , voltage range, rated power, rated frequency. In general, good quality products and printing quality trademark , logo clearly visible, easy to wipe clean with a soft damp cloth , and there is the manufacturer's trademark and related certification mark.

　　The second is the appearance of the lamp . There should be no cracks , loose and interfaces between being prized appearance . During the installation , removal, lamp should not be loose or head tilt phenomenon . Light plastic case must choose the kind of flame retardant engineering plastics , is characterized by its surface like frosted glass texture. The ordinary plastic surface is smooth and shiny , but easy to deform and flammable , is prohibited for the production of energy-saving lamps .

　　Third, working condition. LED lamps under normal operating conditions , the temperature rise should be relatively low, if the conditions are not good heat lamp work beads at high temperatures , light will be great, lamp life will be greatly reduced. Meanwhile, when the lamp is lit on and off , if there is rapid flashing, also shows that there are quality problems.

　　Fourth, the work sounds. EMC is a project that must be passed appliances , LED lighting products on the packaging must bear the national flag of electromagnetic compatibility testing . We can also determine a small simple tests , with a short-wave radio , when the operation of the lamp , in the vicinity of the radio , the lower the received radio noise , electromagnetic compatibility test described light as possible. Environmental liking the sound mute LED lamps at work , if you can very clearly hear the voice of the lights work , indicating the lamp power is not very good .
