Four evaluation results of the exposure of the top 7 brands LED lamp

According to the Yangcheng Metro reported that LED lights gradually out of incandescent light, for consumers, in addition to catch up with the trend, should be more concerned about the safety of LED lamps, energy consumption and the applicability of the family.

In January 2015, in the market to buy a 5 Watt LED bulb with PHILPS, OPPLE, FSL, Linsen lighting, Langshi lighting, three male Aurora state international 7 brand interior, sent to the third party institution comparison test indoor fitness, safety, energy saving etc.. Which LED lights, more "bright blind" your eyes?

Evaluation report: 3 brand LED color rendering index is not up to GB

Buy and send "consumer reports" in the detection of 7 brand interior with 5 Watt LED bulbs, FSL, Mu Linsen, bembom international three samples do not meet the national standard requirements.

Color rendering index is too low will affect the consumer's visual recognition, especially in the room to see some of the critical color will be confusing. Once the color rendering index value is less than 80, it means that it does not apply to indoor lighting occasions, can not meet the relatively high demand for color reduction. Zhang Shanduan, deputy director of the Institute of electric light sources, said Fudan University.

Evaluation report two: heat preservation unqualified hidden fire hazard

Appliance safety, has been the vast number of consumers. A LED bulb light only brightness, energy saving as a selling point is not enough, if the safe use of indicators do not pass, light is bad, heavy may lead to fire.

7 brands of LED bulbs, sample heat resistance Langshi illumination does not meet national mandatory standard requirements. In January 2014 the national quality inspection administration announced the LED national product quality supervision and inspection results of special problems, the products include Foshan Langshi lighting production of a ROSY self ballasted lamp LED Langshi ".

Evaluation report three: light effect is an important indicator of LED lamp energy saving

Inspection of the 7 marked 5 Watt LED bulb lamp in the initial light effect of the larger differences. This international standard 32% virtual light effect, FSL LED lamp more power.

The luminous efficiency is the ratio of the total luminous flux emitted by the light source to the electric power consumed by the light source, which is one of the important indexes to evaluate the performance and the energy saving effect of the LED lamp.

Assessment report four: Blu ray hazards do not worry

Zhang Shanduan pointed out: the domestic LED light sources and lamps have been generally used to reduce the intensity of the LED package device measures, the eyes are generally no blue light hazards. "

Comprehensive test results, only OPPLE, PHILPS, three male Aurora reached the national standard in safety and performance, if you consider the price advantage, while the three hung Aurora bulb is more cost-effective.

Where is the blue light hazard?

As early as 1966, studies have found that blue light irradiation can cause damage to retinal cells, leading to vision loss and even loss.
