Can you use a motion sensor with a fluorescent light?

The short answer to the above question: yes, CFLs are limited. Electronic or digital controls such as timers, photocells, and motion sensors were created to work with the simplicity of incandescent light bulbs, not CFLs.

Can I add a motion sensor to an existing light?

It is possible to add motion to existing outdoor lights. Doing so is simple, in fact, you can even add motion detection without performing one ounce of wiring.

Do motion sensor bulbs work in any fixture?

If your motion sensor has an electromechanical relay, any LED bulb will work fine. If the motion sensor has an electronic switch, the sensor might not be compatible with low-wattage LED bulbs as they require a minimum load to power the sensor on the circuit.

Do you need an electrician to install a motion sensor light?

If you already have an exterior light fixture, you can simply replace it with a motion sensor light — no electrician required — and if you want to install one in a place in which there is no existing light fixture, the procedure for running wires and installing an electrical box is no different than it is for …

Can you use compact fluorescent bulbs outside?

Can I use CFLs outside and in my garage during the long, cold winter? Answer: Yes, they’re great energy savers outdoors, but beware. Older fluorescent lights—both compact and tubular—are powered using magnetic ballasts.

How do you install a motion sensor in a shop light?

Quote from the video:
Quote from Youtube video: First step is to remove the old light switch pull off the cover this one was painted on so I had to use a utility knife and cut around the paint. Pulling these apart is fine with the power-on.

Do motion lights need a switch?

A motion sensor light does not need a switch, but it’s still a good idea to add one. A switch ensures that the light won’t turn on unless you actually want it to. If you want the light to stop responding to movement, you will have that option if you’ve installed a switch.

How do you hook up a motion sensor?


  1. Turn off the power at the main breaker switch.
  2. Remove the old light fixture and replace it with the new motion-sensor lights, connecting the white wire to white and the black wire to black with the wire nuts.
  3. Tuck all the wires neatly into the socket.
  4. Points the bulbs and the sensor in the desired directions.

What is the red wire for on a motion detector light?

The red wire must go to the switch leg (the wire actually powering the light fixture) for the switch to operate properly. It won’t destroy the switch if wired backward, but it won’t work right, either.

Can you put a motion sensor on a two way switch?

Yes, you can, under code, but you will also need to have ‘real’ switches also installed. As far as the second part write on a bit of paper, in marker, and stuff it in the the motion sensor junction box.

Can you put a motion sensor on a three way switch?

When using in a 3-way application use one sensor and one standard 3-way switch. Cannot be used with another sensor, or in a 4-way application. WARNINGS AND CAUTIONS: If you are not sure about any part of these instructions, consult an electrician.

Does a PIR need a neutral?

For the PIR, you would need to take a live and a neutral from the rose or JB, then a switched live back to the rose or JB to as before connect to the live on the fitting. You are going to have to replace the 2 core and earth with 3 core and earth.

Can I replace a light switch with a PIR?

You don’t need to replace the light switch, just install a PIR between the switch and light. Depending on how your light is wired, the switch might not have neutral anyway, so you’ll need to find that first (will be at the light end).

What is a PIR switch?

A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors. PIR sensors are commonly used in security alarms and automatic lighting applications.
