A few Questions one Should Pay Attention to When Purchasing LED Lighting

Obvious energy saving effectiveness, long lifetime, no radiation, no RF interference, no white noise, soft light rays, and a wide operating voltage range are all special features of LED lighting, and becoming well received daily.

As a consumer, how are you able to pick the best product to satisfy your needs with a wide range of LED lights spread out before you?

First is through packaging and trademark. LED lighting products are forced by the country to include the following information on the outside packaging label: voltage rating, voltage range, efficacy rating, and frequency rating. Normally, the trademark of high quality products are printed in excellent quality with clear and distinguished labeling that is not easily wiped away with a damp cloth. There are also manufacturer’s trademark and certification marks.

Second is through the outward appearance of the fluorescent light. On the outside there must be no cracks or traces of flexibility and interface trace of being pried open. During the installation and dismantling process, the base of the light cannot be flexible or crooked. The outer shell of the light, one must choose one that is plastic flame retardant, with a distinguishing feature of the outside having a frosted glass like texture. Lights with the ordinary plastic outside are more smooth and lustrous, but are easier to change shape and com bust, so are prohibited for energy saving light bulb (CFL) manufacturing.

The third is through operating condition. LED lighting in a normal operation condition should have a low rise in temperature. If the requirement for heat radiation is not good, the bulb at a high temperature will have a large lumens depreciation and the lifespan will greatly decrease. Also, if when the lamp when being turned on and off, there is rapid flickering, then it means there is a problem with the quality.

Finally, the fourth is through sound. Electromagnetic compatibility is something that electronics must go through. On the outside of LED lighting products, there must be printed the country EMC test. We can also perform a small test to easily determine this. Place a dual range receiver near the light while it is working. If the amount of noise that interferes with the dual range receiver is low, then this means that the bulb’s electromagnetic compatibility is good. When listening to the LED lamp while it is on in a quiet environment, if the sounds of the lamp is very obvious, then this means that the lamp’s power source is not good.

For consumers that do not have a wide knowledge of electronics, how to quickly, easily, and efficiently purchase a suitable LED product to suit ones needs, one should focus on the following two indicators.

The first indicator is the power and light efficiency. LED lamp comprehensive luminous efficiency refers to the unit of watts/lumens for luminous efficacy. The high the number, the better the energy saving efficiency, so one should purchase a high w/lumen LED lamp. Based on the use of the environment to buy a suitable power sized lamp, the 16W lamp currently on the market can reach up to 200W incandescent light luminous flux, which is enough to fill a 10 ping room with light.

The second indicator is the color rendering index and the temperature color. The color rendering index is an indicator for the light evaluation for an objects color rendering ability, with the perfect standard color rendering index for a light source being about 100. The higher the color rendering index number, the closer the light source is to the actual color.

It is generally known that 80-100 color rendering index is good, 50-79 is average, and anything lower than 50 is considered poor. The unit for temperature color is K. Red colored light rays have a temperature color of between 800K to 900K, yellow with around 3000K, white about 5500L, and light blue being between 8000K and 12000K. The temperature color light source depends on consumer preference. So for example, if a consumer like a warm temperature lamp, they can pick a 3000K temperature color lamp.
