For chaining 4 lights (LED 15W), what wire size should I use? Switch to light circuit already exists and is 12-2 NM.

Assuming the circuit breaker is 20 amps, the entire circuit must be at least 12 gauge wire. You are not allowed to mix smaller gauge wires that are not designed to carry the amperage of the circuit

Never reduce wire size within a given circuit. If switch leg is #12, all branches must be #12 (or heavier). #12 is capable of carrying 20amp total load.

while I am not an electrician, 12-2 is the normal standard in homes, but 14-2 would also work and would be simpler to work with and a little cheaper.

Use same gauge wire, 12-2 NM. This is what is required for a 20 amp breaker line.

After every 3 LED's there is a CUT (scissors) line, and right after that line are 2 round contact points. Solder your new wire leads to these. I found it best to TIN the contacts (because they're under the thin plastic coating) and the wires first, then solder them together. I also use RED wire on the side marked DC12V so I'll always know which is the (+) power side of the strip.

Yes, works perfectly. Go with the 15 Watt and use a cover to mellow out the individual "hot spots" of light. This is far and away better than a 12V CFL.

I'm a electrician 14 guage is fine it doesn't pull any amps bring led. You will be fine with 14 guage wire

For the pair of lights on one switch, the switch should be rated for at least 5 amps.A 27 watt light at 12 volts draws 2.25 amps (27 / 12). Therefore, 2 lights would draw 4.5 amps.Round up to 5 amps.

wire one power supply to both ends 12v DC or 24vac works great / output switch can be NO or NC just move jumper / unit is aligned when LED is lit on receiver. The one with 2 wires is lamp and 4 wires is receiver / if near a window or slider signal may bounce off glass, A tube or tape may help to limit beam. Have fun : )

In a parallel circuit, you just add the watts of each light. 15 watts. But you should have a larger power supply. A 18 watt supply should work.

On mine, there were two solid colored wires (blue & brown?), and one (yellow) with a stripe. When I opened the back of the light, I found that the striped wire just ended and was not connected to anything. My guess is that they found 3-lead wire cheaper than 2 or 4-lead so that's what we get. The other two solid wires seem to work interchangeably as + or -, so they apparently added circuitry to make them idiot-proof. Short Answer: Striped wire: Not used Other two: Connect to 12V DC

Yea, just use a single throw 10 amp DC switch (there some that Amazon sells) which will allow you the ability to add more lights if needed.

As long as you are switching power it should be fine. I used these for lamp switches, but they should work for anything. As to wire size, I managed to get two standard flat lamp cords through one of the openings. Note that I can only speak for AC line voltage use.

This uses a single element 1141 or 1156 bulb, (3/8 inch Bayonet Base) the LED lights I bought did not have an adapter for that size and I ended up having to hard-wire the LEDs to the switch. Some other LEDs do have that size, check to make sure.

You can use anything 40 W or below. Depends how bright you want it. Either way, you'll probably want to put it on a dimmer switch.

Depends on distance and wire size, not just "how many". At 150 foot on 12 guage wire you can run one. 10 lights will need 12 guage wire and you can only run about 13 feet of cable. Buying a bigger transformer will not help with distance.

You're pushing the size limitation for a 4" Oct. box. Additionally, I don't think that the LET151 is compatible with LED lights. Check to confirm...

I bought two sets of 3 light each with adapters, extended length of adapters by cutting in half and soldering various length wire between each half to desired length and connected all six. make sure not to cross connect wires. all working without any problem.

I'm not an electrician, but I did ask if this can be used for LED strips, if this is a regular transformer for low voltage lighting you should be fine. The 12 gauge wire will go a further distance that 14 or 16 gauge.

Yes this kit works, there is actually two wires per lead. I used it to connect four lights with no trouble simply by adding extra wires.
