According to relevant data from the China Lighting Association, the energy consumption of energy-saving lamps is only about 20% of incandescent bulbs. However, in contrast to the "energy-saving" characteristics of energy-saving lamps, the current energy-saving lamps on the market still make consumers more "energy-consuming", and the quality of the products is mixed.
The latest news from the State Administration for Industry and Commerce once again put the energy-saving lamps on the "black list" - according to the quality monitoring of energy-saving lamps in the circulation areas of Beijing, Shanghai and Guangzhou according to the SAIC, the results show that the quality of energy-saving lamps and Not optimistic, the pass rate is only 39.3%. According to reports, of the 61 sets of energy-saving lamps that were sampled, only 24 groups were qualified. The main problems found in the monitoring include harmonic current limit, prevention of electric shock, mechanical strength and other items that do not meet the national mandatory standards.
Just over a year ago, the Hangzhou Industrial and Commercial Bureau conducted a spot check on the energy-saving lamps in the Hangzhou market, and found that the pass rate was only 20%. Among the 10 batches of products examined, 8 batches of products with lamp power, color rendering index, color tolerance, initial luminous efficacy/light flux and other indicators do not meet the national mandatory standards.
The pass rate is so reassuring, how can consumers buy qualified products? Professionals pointed out that consumers can judge whether the purchased energy-saving lamps are qualified by "visual inspection". The object of the visual inspection is the "display index" among them.
“The level of the index displayed in the energy-saving lamp directly reflects the color rendering of the light. The higher the color rendering index of light, the more the color of the object under its illumination can be truly reflected. Otherwise, the object will be made Color distortion." Experts said, we can light the lamp, shine on the palm of your hand, the palm of your hand looks ruddy and bloody, indicating that the color rendering index of this product is high, and if the color rendering index is low, the palm is blue, no color.
