LED lighting products have entered the pioneers of people's lives and are LED bulbs. However, the LED bulbs, which are said to be energy-saving, durable, long-lived and harmless, are presented in front of ordinary people, but they are mixed and mixed, and users are inevitably confused about the choice of LED bulbs.
Randomly selected 14 LED bulb products from the market, tested several key application indicators, and made a horizontal comparison from the application point of view, trying to give the user a general impression.
Second, the selection
Ordinary employees who are not familiar with LED lighting technology purchase directly from the market, such as storefronts, Tmall, Taobao, No. 1 store, etc., all retain invoices.
The 14 products are all new products officially available from the manufacturer. The nominal power is from 5W to 6.3W. This evaluation is based on the 5W level.
Third, test instruments and software
Distributed photometer: remote GO-R5000, test product's electric power, luminous flux, light distribution
Integrating sphere: remote PMS-80, test the light color parameters of the product
Strobe tester: remote LFA-2000, test product strobe parameters
Lighting Analysis: Lighting Analysts AGI32 V2, calculating the lighting effects of analog products
Fourth, product identity
Because the model marking methods of different manufacturers are very different, and some products have no models inside and outside the packaging, this evaluation first encountered the problem of being unable to verify the correctness. For the convenience of writing, this evaluation starts with a simplified name for the product, as shown in Table 1.
