| Because there are three LEDs in series, you cannot drive these LEDs from a 5V supply. The LED strips say "+12V" on them to mark the anode and that's the maximum voltage we suggest. We've found that if you're ok with them being a little dimmer, even 9VDC works very well. | Because there are three LEDs in series, you cannot drive these LEDs from a 5V supply.

| To find the total maximum current draw per meter, we would multiply 60mA x 10 (ten segments per meter) = 0.6 Amps per meter. Again, that's assuming you would have all the LEDs on at once and that you are powering it from 12V. If you're going to be PWM-fading between colors, maybe 1/2 of that is what you'll be drawing. Still, you do need to have a fairly decent power supply to run this strip, all those LEDs add up! | To find the total maximum current draw per meter, we would multiply 60mA x 10 (ten segments per meter) = 0.6 Amps per meter.

| + | Connecting up to the strip is fairly easy, you'll want to solder four wires to the copper tabs. We'll use white for +12V, then red, green and blue wires for the corresponding LED colors. | ||

| + | Cut away the waterproof overmolding at one end of the strip. The strips are symmetric so it doesn't matter which end you use | ||

| + | Solder the four wires on. We used stranded wire, which is more flexible and is probably a better choice than solid-core | ||
