HI,
I HAVE ONE CUESTION ABOUT, HOW TO MAKE THE TESTING OF LEDS??
BECAUSE I HAVE MANY MESUREMENTS WITH 5MA AND WHEN INCREASED THE CURRENT THE LUMEN IS DROOP ABRUTALI
FOR EXAMPLE: BLUE
5 MA ------- 20 LM/W
20 MA------- 10 LM/W: eek:
Led is less efficient in higher current.
Look at graph of otput as current function and you will see it's not linar
You might have overdriven the led do its efficiency droped so much
