LED bulb light performance tests: at 25 ℃ ± 1 ℃ ambient temperature and the rated voltage, rated frequency 9w bulb brand, with integrated spectrum measurement test system, bulb sample is placed inside the sphere, to avoid direct light emitted the test probe. 0.5h lit after the test. Bulb luminous flux and luminous efficiency. At ambient temperature 25 ℃ ± 1 ℃, with the luminosity distribution test system measurement. First test lamp luminous flux and light intensity distribution 9w bulbs, lamps light efficiency ratio of the actual power consumption for LED bulb lamp luminous flux. led energy saving lamps Specifications Glossary: ??General LED lights with different colors have different luminous intensity 9w bulb plant, common units mcd, namely cents Candela. The higher the value 9w bulb prices, indicating the greater luminous intensity, which is brighter. This is an important indicator of assessment LED lights with brightness, the brightness of the lights with the requirements of the higher price is more expensive. This is because of the high brightness LED chip price of your side, and the brightness, the greater the difficulty the package. 9w bulb prices, Hang Li saving (certified), 9w bulb provided by Anyang Hi-tech Zone Heng Lai energy-saving lamp factory. High-tech Zone Anyang Heng Lai energy-saving lamps factory (www.ayhljnd.com) is Anyang, other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Hang Li leadership in energy efficiency with the staff warmly welcome all inquiries negotiations to create a constant Korea saving a better future.
