High/Low light LED switch Answered
I recently purchase some 3528 300p LED Strip Light so that I can make some under cabinet
lighting. I wanted to make my own because I believe I can to it for a much better price
and learn something in the process rather than buying an LED light set from a big box
I have a 3 position rocker switch Off/high/low. If possible I would like to use the LED
lights in a High/Low configuration. From what I read they make PWM modules that control
the LED making them appear to be dimmable, but I do not want to use one of these devices.
For the low setting I was considering wiring in a POT or an inline resistor to drop the
Voltage to the LED's. On second thought I suspect that this would not work and if I drop
the voltage too low this would result in inoperable LED's. By the way I would not be opposed using an inline resistor if this is a good way to reduce the light level
Is there some cheap electronic component that will produce or simulate an approximate 50%
PWM that I can wire inline with the switch, in effect producing a low lighting mode? I
am not interested in using a variable PWM control, I just want to achieve a switchable
high/low lighting. I am not familiar with components and I hope you could suggest a few
ideas for my project.
Some details: The led strip will be ~11 linear ft using 12VDC and about 40W of
