With the rapid growth and popularity of LED lighting products. Now many families are also using LED energy-saving lamp, because LED lamps have obvious energy-saving effect, long service life, and no radiation, no stroboscopic effect, no noise, soft light and wide working voltage range and other characteristics are increasingly welcomed by consumers. But the current market of LED lights is very complex, the following teach you how to distinguish the quality of LED lights. Start with the following methods, only three minutes to identify the quality of LED lights good or bad!
Roughly judge the quality of LED six kinds of parameters:
1. the luminous flux (φ) unit is lumen (LM)
2. color temperature (K) unit is Kelvin
3. Chromogenic property (RA) chromogenic index
4. Light source efficiency (LM ∕ W)
5. Power factor of power supply
6. Heat dissipation effect
