Just joined and im getting great info from this forum.
I want to install under cabinet lighting, for cheap! So i want to purchase battery powered, LED puck lights, and run them on wall power rather than on the 3 AAA batteries. I am extremely new to electrical work, but otherwise handy. I intend to use a wall wart but i dont know what voltage to use, nor how much current. I want to connect 4 of these lights to one switch and one power source. I appreciate any direction and help. Thanks a lot!!
3 AAAs means that the intrinsic fixtures would prefer to operate on ~3.5 to 4.7V. A 5V 300mA retired cell phone charger would run several of these fixtures.
Caution: anything designed to run on AAAs will be marginal for undercounter illumination. I just went through this. I used 12V 10W lamps spaced about every three feet, and those are about right. I mounted a 150VA transformer in the attic to run these.
