How to choose the qualify LED tube light
The LED tube light is highly professional light, most people could not make sure which one is better, the following five skills is to tell you how to choose the preferable LED tube light without instrument
1, inspect Packaging and labeling
According to the standards of the National compulsory product, LED lighting manufacturer must mark the following information on the packaging: Rated voltage range, rated power, rated frequency. Under normal circumstances, the high-quality manufacturers?trademarks and related certification mark is legible and not easy to fall off, even wiped with a soft damp cloth, logo is clearly visible,.
2, inspect the appearance of the LED tube light qualified LED tube light. From the point of view of the lamp, the more consistent the lamp shape and size is, the better the quality. Of course, there should be no cracks and the loose on the tube and between the interface. The housing of the LED tube light must be made of the engineering plastics flame retardant plastic PC. Ordinary plastic deformation and flammable, the aluminum must be lit.
3, inspect the working temperature
The temperature of the LED tube light should be low during normal operation. Otherwise, LED lamp life is very short. Meanwhile, when the energy-saving lamp is lit, the rapid flashing or very harsh fluctuations indicate that the energy-saving lamps exist the quality problems. Energized after a few minutes, the temperature should prove good heat dissipation, using the aluminum plate to abstract heat. No temperature demonstrate that the fiberglass panels is used, heat cann't be timely dissipated.
4, inspect start-up performance There is one characteristic for the LED tube light start: power that is bright, does not blink.
5, weighed, the heavier LED tube light is relatively better than the light, marking that the heavy is made of good material.
Knew how to choose a good LED tube light,then how to find a good LED manufacturers is also the key, which mainly rely on consumer good reputation,the Lead lighting has been continuously improving Production and R & D team, strictly applying qualified LED chips, drivers, housing, radiator to produce all kinds of LED flood light, LED tube light, LED tunnel light and other indoor and outdoor LED lighting, high brightness SMD is used as the light source of the LED tube light and highly integrated and high brightness COB as the light source of the LED flood light, which fully guaranteed stability and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while LED tube light and LED flood light use low voltage constant current driver, which current the alternating into direct current so that improve energy efficiency and reduce the waste heat energy and stroboscopic effect excite the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, thatnot why the LED light is famous for energy-saving and environmental protection ,login www.gcledlight.com to learn more features and uses of the LED tube light and surf www.gcledlight.com to know more awesome LED floodlights and other LED lighting
