Identification of the merits of LED lamps

LED energy saving lamp energy-saving effect is obvious because of its long life, no stroboscopic effect, no noise, light, soft and wide operating voltage range of features and increasingly welcomed by consumers. But the current energy-saving lamps on the market led many, the quality varies greatly. How to light an array of energy-saving lamps in the shop to buy their satisfaction with the products? Through the "four to see" the merits of energy-saving lamps can be identified, described below.
A look at packaging and labels
National mandatory product LED tube manufacturers in the packaging marked the following: the rated voltage range, rated power, rated frequency. In general, a trademark of printing high-quality products of good quality, legible, easy to fall off, with a soft damp cloth, signs legible, indelible, have the manufacturer's trademark and related certification mark. Shoddy products, poor quality printing, fonts, fuzzy, easy to erase, no manufacturer's trademarks and related certification mark.
Second, look at the appearance of LED lamps
The real energy-saving LED lights, with three color tubes, tube white, hand cover, even more white, while more than two tubes together to compare the shape and size lamp consistency better than large-scale products, quality is guaranteed. The shell can not have cracks, loose, the seal should not have been prized in the installation, demolition process, lamp should not be loose, head tilt phenomenon.
Third, look at working temperature
LED energy saving lights in normal operation, 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, indicating that the energy-saving lamps are of questionable quality.
Four to see start-up performance
LED energy saving lamp start has two characteristics: First, the higher the temperature the easier starts; Second, turn off lights, not flash. It is also worth mentioning that opened a lot of LED lamps is very dark, which is detrimental to lamp life, LED energy-saving lamps should be equipped with its internal power supply circuit and PCB board
