Due to the instability of grid voltage, the current and brightness fluctuate. The price is moderate and the quality is slightly better. Three categories, LED energy-saving lamps, made of high power SMD LED constant current power supply adopt isolation circuit, with a constant current, such as 5 w LED, usually adopt 5 pieces of 1 watt LED chips, series, using constant current 300 ma current source power supply, wide voltage power supply, make the power grid volatility, not change current, flux that maintain a constant brightness.

In addition, different light source color temperature, light color is different: Color temperature below 3000k has a warm feeling, to achieve a stable atmosphere; Color temperature in 3000k-5000k for the middle color temperature, there is a refreshing feeling; Color temperature above 5000k, there is a cold feeling. Luminous Intensity (I, Intensity) : Unit of candela, namely cd. The luminous flux emitted by a light source in a unit solid Angle in a given direction is defined as the light intensity (degree) of the light source in that direction.
