LED energy-saving lamps because of its energy-saving effect is obvious, long life, no stroboscopic effect, no noise, a wide range of soft light voltage characteristics of the increasingly welcomed by consumers. However, LED energy saving lamps on the market today, the quality varies greatly. An array of energy-saving lamps lighting shop to buy their satisfaction with the product? Through the merits of "four of" can identify energy-saving lamps are described below.
A look at the packaging and labels
The national mandatory LED Power Supply lighting manufacturers products are marked on the outside of the package the following: the rated voltage range of rated power, rated frequency. In general, good quality products of the trademark printing quality, legible and easy to fall off, wipe with a soft damp cloth signs legible, indelibly, there are manufacturer's trademarks and certification marks. Shoddy products print quality is poor, fuzzy fonts, easy to erase, no manufacturer's trademarks and certification marks.
Second, to see the LED lamp appearance
LED Blue 150W energy saving lamps, tricolor tube, the tube white, hands over to look more white, while the tubes together, tube shapes and sizes in good agreement with mass products, quality is guaranteed. The shell can not have cracks, loose, the seal should not have been prized in the process of installation and removal, lamp should not be loose, head tilt phenomenon.
Third, look at the working temperature
LED 400W energy-saving lamps in normal working condition, the temperature should be low. Otherwise, LED energy saving lamp life is very short. The same time, the energy-saving lamp is lit, quickly flashing or glare fluctuations show that the energy-saving lamps to quality problems.
Four to see start-up performance
LED 200W energy-saving lamps to start with two characteristics: First, the higher the temperature, start the easier it; the lights off, do not flash. In addition, it is worth mentioning that a lot of LED energy saving lamps open a very dark, this lamp life adversely, LED energy-saving lamps should be equipped with its internal power supply circuit and PCB board
