The brightness of e27 led light bulb

     Most of people think of LED bulb wattage is higher, its brightness is bigger, in fact this is wrong. The brightness of e27 led light bulb has the following three factors:
     1. Light lamps with LED beads. Different input current will let LED have different lighting effect, often to reduce the supply current is higher than the full power supply light effect. The same power, high light efficiency of high brightness.
     2. LED series parallel form inside the lamp. The same light effect of the LED, the less number of parallel series, required input current is small, this time even if the input current is small, but the brightness of the LED lamp more will be higher.
     3. Source model e27 led light bulb uses a different input current, the same light effect of high and low. 120lm/w on the market, with 80lm/w beads, and supply current.
