how to identify the pros and cons of LED lamps

LED lamps because of its energy-saving effect is obvious, long life, no stroboscopic effect, no noise, light and soft features wide operating voltage range and increasingly welcomed by consumers. But now LED lamps on the market a lot of mixed quality. How to choose their own satisfaction with the product in the lighting store an array of energy-saving lamps? By "five watch" the merits of energy-saving lamps can be identified, described below.

A look at packaging and labels

National mandatory buy led high bay lamps products manufacturer in the packaging marked the following: Rated voltage, voltage range, rated power, rated frequency. In general, good quality products, label printing quality, legible, easy to fall off, wipe with a soft damp cloth, signs legible, indelible, there are manufacturers of trademarks and related certification mark. Poor print quality and shoddy products, fonts, fuzzy, easy to erase, no manufacturer's trademarks and related certification mark.

Second, look at the appearance of LED lamps

True LED lamps, with tricolor pipes, white, hands over look whiter. Also, speaking from the lamp, the lamp can put more than just put them together, tube shapes and sizes, mostly good consistency bending molding machines, mostly mass-produced products. Good product consistency, quality assurance easier interchangeability of better maintenance. Of course, it can not have cracks between loose and interfaces are prized appearance. During the installation, demolition process, there should be no cap loose, head tilt phenomenon.

Lights must choose the kind of engineering plastics flame retardant plastic case type. Ordinary plastic deformation and easily flammable, is prohibited for the production of energy-saving lamps. On the surface can be easily distinguish between the two, the latter surface is smooth, shiny, former surface texture similar to frosted glass.

Third, look at the temperature at work

LED energy saving lamp under normal operating condition, the temperature should be low. Otherwise, LED energy saving lamp life is very short. Meanwhile, energy saving lights, there are flashing quickly, or very harsh fluctuations, shows the existence of quality problems that energy-saving lamps.

Four to see start-up performance

LED lamps start with two characteristics: First, the higher the temperature, the easier start; two, turn off lights, not flash. Also worth mentioning is that many LED lamps opened very dark, which is detrimental to the life of the bulb, LED energy saving lamp shall be provided with power supply circuit and PCB board in its interior.

Five look interference

In China, the electromagnetic compatibility is electrical project must, however, led high bay light for sale is very complex to detect when the user purchases a lamp to see if there is electromagnetic compatibility testing by the national flag, the second is with a shortwave radio on the packaging, when when the lights work, placed near the radio, shortwave radio should not lower the noise emitted by radio at EMC test lamp better.
