Light LED energy-saving lamps "quality uneven in quality identification four"

LED energy-saving lamp because of its obvious power saving effect, long service life, no noise, no stroboscopic effect, soft light, wide working voltage range and other characteristics are increasingly welcomed by consumers. However, the current market led a lot of energy-saving lamps, the quality varies greatly. How to shop in the lamps and lanterns of energy-saving lamps to buy their own products? The advantages and disadvantages of the energy saving lamp can be identified by "four look".

At packaging and trademark

National mandatory LED lamp manufacturers in the packaging marked with the following: rated voltage, voltage range, rated power, rated frequency. In general, the quality of the product quality of the trademark printing, font clear, not easy to fall off, with a soft wet cloth to wipe, the mark clearly discernible, not easy to wipe off, there are manufacturers of trademarks and related certification mark. Poor quality printing products, the font is fuzzy, easy to erase, no manufacturer's trademark and related certification mark.

Two LED lamp appearance

LED energy-saving lamp real, with three tubes, tube white, hand over, more white, and the plurality of lamp tubes together, tube shape and size consistent is the product of mass production, quality assurance. At the same time, housing can not have cracks, loose, the seal should not have been prized, in the process of mounting and dismounting, the lamp should not be loose, head tilt phenomenon.

Three see working temperature

LED energy-saving lamp in normal working condition, the temperature rise should be low. Otherwise, LED energy-saving lamp life is short. At the same time, when the energy-saving lamp light, there is a quick flashing, or very dazzling fluctuations, the quality of the energy-saving lamps are described.

Four see start performance

LED energy-saving lamp start has two characteristics: one is the higher the temperature start more easily; two is the lights off, no flash. In addition, it is worth mentioning that, a lot of LED energy-saving lamp is very dark, which is detrimental to the life of the lamp, LED energy-saving lamps should be equipped with power supply circuit and PCB board.
