3 volt LED Strip - Warm White - 30 cm (18 LEDs) as used in our coach lighting kits.
You can cut these every single LED to the length you require and then you just need to solder wires to the solder pads on the strips.
You can use AAA, AA or CR2032 batteries for these strips but make sure not to use rechargeable batteries as these can put out more than 3 volts when fully charged and may blow the LEDs. Battery holders are available on our Power Supplies page.
We also have a 3 volt 1 amp power supply available on our Power Supplies page.
