The variations are always within the same spectrum, just if you buy LEDs of the same color in many different batches, there is likely to be some slight variations (even if our eyes don’t notice them). Once the voltage dropped across an LED reaches the forward voltage, your LED will light up. The interesting thing about this measurement of light, the candela, is that it isn’t the measure of the amount of light energy, like most other light forms are measured, but rather the actual brightness. The example above, when your input voltage and forward voltage are so close, is the one example where you will not need to worry about current much. 8mm and 10mm models are used to output as much light as possible. … Check out LuxDrive’s DynaOhm. Diodes have what is called a forward voltage rating which determines the minimum voltage difference between the Anode (+) and Cathode (-) in order to allow electrons to flow (ahhh..sweet electricity). So we take this LED and try to hook it up to an AA battery, will the LED do anything? high-power LEDs this is done with a constant current driver. The name 5mm LED is dubbed from their dimensions: the epoxy case on top is about 5mm in diameter. Let’s use the same blue LED from the example above.
