Ultra Low Power LED

The days of 20mA currents for LED's are over. New LED's operate on currents less than 2mA.

 Ultra Low Power

A low power LED I've been using in my designs is the Broadcom / Avago HLMP-K150-C0002. It's a 3mm LED that lights up very well at just 0.5mA.

(Images show my ultra low power Direct Box design where I operate them at just 250uA!)


Get these for your low power projects at Digikey or Mouser. Comments always welcome.
