Green led efficiency

WebLuminous efficacy is a measure of how well a light source produces visible light. It is the ratio of luminous flux to power, measured in lumens per watt in the International System of Units (SI). Depending on context, the power can be either the radiant flux of the source's output, or it can be the total power (electric power, chemical energy, or others) … WebAssuming that a single green LED with 10mA forward current should have a constant operating voltage of 5V, the series resistor R V equals (5V -V F,10mA )/10mA = 300Ω. …
