How To Choose High-quality LED Energy-saving Lamps

LED energy saving lamp, because it has no ultraviolet light, no radio frequency interference, and compared to traditional incandescent or fluorescent lamp, longer life. Wide voltage and constant current design are becoming more and more popular with consumers. But there are many LED energy-saving lamps on the market, and the quality is uneven. How to choose the satisfied products in the energy-saving lamps in the lamps and lanterns shop? Through the "four parts" can identify the advantages and disadvantages of energy-saving lamps,

See packaging and trademarks

The state requires LED manufacturers of lamps and lanterns to mark out the following contents on the outer package: rated voltage, voltage range, rated power and rated frequency.  Generally speaking, the quality of the trademark printing of good quality products, fonts clear, not easy to fall off, wipe with a soft wet cloth, signs clearly discernible, difficult to erase, there are manufacturers of trademarks and related certification mark.  Inferior products are poor in printing quality, blurred in fonts, easy to erase, no manufacturer's trademarks and related certification marks.

Look at the appearance of the LED tube

LED energy-saving lamp is 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.

Look at the temperature at work

LED energy-saving lamps in normal working conditions, the temperature rise should be very low. Otherwise, LED energy-saving lamp life is very short. At the same time, energy-saving lights are lit, there is a rapid flashing, or very dazzling fluctuations, indicating that the energy-saving lamps exist quality problems.

See boot performance

LED energy-saving lamps start with two characteristics: first, the higher the temperature, the easier it is to start; two, the lights turn off and will not flash. In addition, it is worth mentioning that, many LED energy-saving lamps open very dark, which is detrimental to the life of the bulb, LED energy-saving lamps should be equipped with power circuit and PCB board inside.
