Looking for a formula; I have a 24v 1.7 amp power supply ( http://www.allelectronics.com/make-a-store/item/PS-2417/24VDC-1.7A-POWER-SUPPLY/1.html ) to light 2 - 24v led strips ( http://www.allelectronics.com/make-a-store/item/LBR-24/24-WHITE-LED-LIGHT-STRIP-24VDC/1.html ). I want to be able to dim the led's from full power to completely off, but don't know how to calculate what size of potentiometer would give me the right ratio for dimming. IE, I don't want the LEDs to be completely off when the pot is only halfway turned. The urls are links to the exact products I purchased. Also, the power supply seems kind of large, and I still have to enclose it, so if anybody knows of a better and cheap path to get 24v that involves a little less potential for death, I'm all ears. Thanks!
