Can you use thermostat wire for led lights?


No, thermostat wire shouldn’t be used for LED lights. The voltage drop will have a big effect on how well the lights work. A lighting system with 12 volts has 10 times as much current as the same system with 120 volts. Class 2 wiring is only for low-voltage uses, like doorbells and security systems. It’s not meant to be used for high-voltage things like LED lighting. Use the size and type of wire that your LED lighting system says to use for the best results.

Why you shouldn’t use thermostat wire for LED lights?

Even if the supply is called Class 2, you shouldn’t use small gauge wire like thermostat wire. The voltage drop will have a big effect on how well the lights work. A lighting system with 12 volts has 10 times as much current as the same system with 120 volts. Class 2 wiring is only for low-voltage uses, like doorbells and security systems. It’s not meant to be used for high-voltage things like LED lighting. Use the size and type of wire that your LED lighting system says to use for the best results.

What type of wire is used for LED lights?

For LED lights, 14-gauge, two-conductor cable with a ground wire is the best type and size of wire to use. The ground wire is important because it gives electricity a way to flow if the circuit shorts out. 14-gauge wire is thick enough to handle the high currents that come with LED lighting, but not so thick that it is hard to work with. Two-conductor cable has two insulated wires inside a single outer jacket. Most of the time, the ground wire is bare (not insulated).

Do you need special wiring for LED lights?

No, LED lights don’t need special wiring. For LED lights, 14-gauge, two-conductor cable with a ground wire is the best type and size of wire to use. The ground wire is important because it gives electricity a way to flow if the circuit shorts out. 14-gauge wire is thick enough to handle the high currents that come with LED lighting, but not so thick that it is hard to work with. Two-conductor cable has two insulated wires inside a single outer jacket. Most of the time, the ground wire is bare (not insulated).

Can I use 12 gauge wire for LED lights?

No, 12 gauge wire shouldn’t be used for LED lights. For LED lights, 14-gauge, two-conductor cable with a ground wire is the best type and size of wire to use. The ground wire is important because it gives electricity a way to flow if the circuit shorts out. 14-gauge wire is thick enough to handle the high currents that come with LED lighting, but not so thick that it is hard to work with. Two-conductor cable has two insulated wires inside a single outer jacket. Most of the time, the ground wire is bare (not insulated).

How thick of a wire do LED can lights need?

For LED can lights, you should use 14-gauge cable with two wires and a ground wire. The ground wire is important because it gives electricity a way to flow if the circuit shorts out. 14-gauge wire is thick enough to handle the high currents that come with LED lighting, but not so thick that it is hard to work with. Two-conductor cable has two insulated wires inside a single outer jacket. Most of the time, the ground wire is bare (not insulated).

The dangers of using thermostat wire for LED lights

Don’t make the mistake of putting LED lights on wire from a thermostat. Find out about the risks and why you shouldn’t do it.

Putting LED lights on thermostat wire is dangerous because the voltage drop will have a big effect on how well the lights work. A lighting system with 12 volts has 10 times as much current as the same system with 120 volts. This can hurt your LED lights and wiring in a big way. Class 2 wiring is only for low-voltage uses, like doorbells and security systems. It’s not meant to be used for high-voltage things like LED lighting. Use the size and type of wire that your LED lighting system says to use for the best results.

Why it’s not a good idea to use thermostat wire for LED lights?

Using thermostat wire for LED lights is not a good idea because the voltage drop will make the lights work much worse. A lighting system with 12 volts has 10 times as much current as the same system with 120 volts. Class 2 wiring is only for low-voltage uses, like doorbells and security systems. It’s not meant to be used for high-voltage things like LED lighting. Use the size and type of wire that your LED lighting system says to use for the best results.

In conclusion

Using thermostat wire for LED lights is not a good idea. The voltage drop will have a big effect on how well the lights work. A lighting system with 12 volts has 10 times as much current as the same system with 120 volts. Class 2 wiring is only for low-voltage uses, like doorbells and security systems. It’s not meant to be used for high-voltage things like LED lighting. Use the size and type of wire that your LED lighting system says to use for the best results.
