LED DRIVER assistance required? Answered
I am trying a diy led build. I have 9 3w 4v 800mah high power leds and a 240v AC to 26-39v variable voltage DC 1500mAh fixed driver.
My first question is, if I connect my 9 leds in series =36v leaving 3v drop do I need to limit the fixed 1500mAh current and if so how.
My second question, is there a way of fitting a dimming circuit given that I cannot access the internals of the driver.
I have looked for answers but cannot find oe specific to my problem
Many thanks in advance for replies.
