Costco has these very nice looking under the counter battery operated (3 AAA) lights. The lights head swivel and there are to light levels. The LEDs are very bright but not Luxeon.
Not wanting to mess with changing batteries all the time I thought maybe I could hardwire them. So I found a power source rated at 3.7 VDC and tried to light up the leds. They would not work. Anyone knows where I went wrong?
