LED energy saving lamp energy-saving effect is obvious because of its long life, no stroboscopic effect, no noise, light and soft and wide operating voltage range of characteristics of an increasingly welcomed by consumers. But the current energy-saving lamps on the market led many, the quality varies greatly. Of the light fixture store to buy an array of energy-saving lamps in their satisfaction with the products? By "four to see" the merits of energy-saving lamps can be identified, described below.
A look at packaging and labels
State LED lighting manufacturer mandatory for products in the packaging marked the following: rated voltage, voltage range, rated power, rated frequency. In general, high-quality products of good quality and trademark printing, fonts, clear, easy to fall off, with a soft damp cloth, signs clearly visible and difficult to erase, a manufacturer's trademark and related certification mark. Poor print quality and inferior products, fonts, fuzzy, easy to erase, no manufacturer's trademarks and related certification mark.
Second, look to see LED lamps
The real energy-saving LED lights, is to use three-color tube, tube white, hand cover, even more white, and can put together to compare more than just lamps, lamp shape and size much better consistency of large-scale Products, quality is guaranteed. The shell is not cracked, loose, the seal should not have been broken at the scene, in the installation and removal process, the lamp should not be loose, head tilt phenomenon.
Third, look at the temperature of the work
LED energy-saving lamps in the normal working condition, the temperature should be low. Otherwise, LED energy saving lamp life is very short. Meanwhile, energy-saving lamp is lit, a quick flashing or very harsh fluctuations, shows that the energy-saving lamps are of questionable quality.
Four start-up performance to see
LED energy-saving lamps start with two characteristics: First, start the more likely the higher the temperature; Second, turn off lights, not flash. In addition, it is worth mentioning that a number of energy-saving lamp LED open very dark, which is bad lamp life, LED energy-saving lamps should be equipped with its internal power supply circuit and PCB board.
