Due to the feature of high efficacy and energy efficient, long lifetime, no stroboscopic effect and noise, soft light and a wide range of working voltage, LED light has gradually become more and more popular. However, there is a variety of LED light in the market and the good and the bad are mixed together. How to identify the quality of LED light and choose the best one?
Package and logo: The country compulsively demands all the LED Light manufactories must mark the important contents in the product package, including rated voltage, the range of voltage, rated power and rated frequency. Generally speaking, the printing logos of high-quality products are so good that they are still legible and not easy to erase. Besides, they are always included their logo and related certification. On the contrary, the printing logos of low-quality products are so bad that the words are fuzzy and easy to erase. Besides, they won’t provide any logo and related certification.
The appearance of LED light: Putting many LED lights together, if the majority of them are consistent in shape and size, it means they are produced by machine from big manufactories. When the consistency of product is fine, the quality is easy to be guaranteed and it’s much more convenient to maintenance. Of course, there are no obvious crack and looseness in the appearance. In addition, check the smooth finish of light parts and the size of the welding spots to make sure all of them have the same size.
Working temperature: On normal working condition, the temperature of LED light is low. Otherwise, its lifetime is very short. When switching on the fixture, if there’s a quick flicker or dazzling fluctuation, it means the light has some quality problems.
Starting performance: There are two characteristics when starting: the first one is that the higher the temperature is, the easier the starting is; the second one is that switch off the light without flicker. Meanwhile, it’s worthy to point out that some lights are dark in starting, which is harmful for the lifetime. There should be power circuit and PCB in the internal of fixtures, such as led high bay .
