I’II start off with a quick and dirty on the IOS 3 mode driver.
Using two King Kongs with a combined voltage off 4.05 volts, the following current measurements were taken at the led.
Low .08 amps.
Med .7 amps.
High 2.88 amps.
Edit. It was asked if I could measure this driver running 3 26650’s off which I thought would make no difference. Surprisingly there is. Why I have no idea. 3 x Trustfire protected 26650 measuring 12.2 volts.
Low .09 amps.
med .84 amps.
High 3.6 amps.
Used in this light.
