What gauge wire for led recessed lights?
Typically, a 12-gauge cable with two insulator conductor wires and a ground wire are used. State or city electrical codes may require a specific type and/or gauge of wire to safely install recessed lighting fixtures.
Typically, a 12-gauge cable with two insulated conductor wires and a ground wire are used. The cable is jacketed with a non-metallic plastic jacket to protect it.
Wire Gauges and Sizing
Many appliances and household lighting fixtures need wire that is around 12- or 14-gauge. This requirement is mentioned as a number, dash, and another number.
True 16 AWG LED strips extension cable from TyumenDirect that is ideal for all single color LED strip light, low voltage single color led strip, light bulb, lamp. It is widely used for various DC electrical hookups, low voltage cables, 12V DC, 24V DC, low-loss in-home or car stereo installs.
Using the basic electrical formula "Watts = Volts x Amps," the wire presents the equation Watts = 120 x 20 with a result of Watts = 2,400. You can load 2,400 watts onto your 14-gauge wiring for a 120-volt circuit.
We've found solid 20 and 22 AWG wire options, which work for most systems that use single color LED lights.
Yes, it is okay to use 12-2 cable to supply lighting fixtures. The other answer indicates that it even with 12-2 you have to use a 15A breaker for lighting circuits which is not strictly correct. If the entire circuit is 12AWG (other than fixture wires), then a 20A breaker may be used.
18 Gauge Wire Applications:
18 gauge 2 conductor wire (red/black) is a low voltage wire for LED lights that can be used in order to leave space in between segments of single color 24V LED Lights or connect your lighting installation to power.
To determine what gauge wire you need, consider the carrying capacity and the amount of current the wire needs to conduct (measured in amperage or amps). Wire gauge is directly related to how many amps you need to run through it. The distance you need the wire to go can also impact the gauge of wire you need.
LED lights don't need special wiring. They'll work with any standard light fixture, as long as it isn't enclosed, which could cause heat damage. Poor wiring can cause electrical interference, but this is easily solved with a suppressor.
Is it OK to use speaker wire for LED lights?
A lamp draws very little current, especially with modern LED bulbs, so ordinary speaker wire of even 18 or 20 gauge is fine.
LED lights by their nature are low voltage but also relatively low current making them lower in power and more efficient that traditional incandescent bulbs and halogen downlights. Generally we are talking about between 100 to 750 milli-amps depending on the forward voltage required to turn on the LED.
Therefore, a 15amp circuit can safely accommodate 180 or more fixtures using LED or CFL bulbs.
Assuming a 60 watt light, you can put up to 24 lights on a 15 amp breaker. If you are using low-wattage LED bulbs, an LED bulb using 10 watts, you can install up to 150 bulbs on a single circuit.
Maximum Lights Per Circuit
Technically, you can install 13 outlets or lights on a 20-amp CB, but you can only put ten lights per circuit due to the 80% rule of maximum continuous load.
| Wire Use | Rated Ampacity | Wire Gauge |
|---|---|---|
| Low-voltage lighting and lamp cords | 10 amps | 18-gauge |
| Extension cords (light-duty) | 13 amps | 16-gauge |
| Light fixtures, lamps, lighting circuits | 15 amps | 14-gauge |
| Kitchen, bathroom, and outdoor receptacles (outlets); 120-volt air conditioners | 20 amps | 12-gauge |
Even if the supply is listed as Class 2 using small gauge wire such as thermostat wire is a bad idea. The voltage drop is going to greatly effect the lighting performance. There is 10 times as much current on a 12 volt lighting system as there is for the same system operating at 120 volts.
We recommend 12-gauge or 10-gauge wire for long distances. This is to prevent voltage drop. The further you get from the transformer and its power supply, the more resistance occurs in the circuit which causes the voltage to decrease.
12-gauge wire is the minimum requirement for outlets on a 20-amp circuit. 12-gauge wire can be used for outlets on both 15 and 20-amp circuits. 14-gauge wire is unsafe to use for outlets on a 20-amp circuit. 14-gauge wire can only be used for outlets on a 15-amp circuit.

“Twelve-gauge wire is good for 20 amps, 10-gauge wire is good for 30 amps, 8-gauge is good for 40 amps, and 6-gauge is good for 55 amps,” and “The circuit breaker or fuse is always sized to protect the conductor [wire].”
