[ad#block]Electrical Question: What is causing our recessed light to go on and off all by itself?
- We have an existing recessed light that was installed by the builder which is located near the shower.
- A flat toggle switch operates the lamp.
- My wife swears the light just comes on by itself and then off.
- I told her to firmly switch the lamp off when using it.
- She thinks I am the problem for not fixing a problem.
- What is going on here (with the lamp)? condensation issues?
- The lamp is cover by glass and has frame, any ideas?
This recessed lighting question came from: Dan, a Homeowner from Petaluma, California.

Thanks for your recessed flush light question Dan.
The On and Off Problem of Recessed Lights
The High Temperature Safety Feature of Recessed Lights
- I’m very familiar with this situation and have seen this occurrence many times.
- What is happening is the recessed can lights have a high-temp safety switch mounted into the top of the enclosure which will turn the light off if it gets too hot.
- The light fixture then cools down, and after a few minutes it will come back on. This is especially true with light fixtures that use incandescent light bulbs.
- This occurrence is not a problem or fault of the light fixture, in fact it is a great safety feature that prevents the light fixture from over heating which could possibly lead to a fire.
- This is on and off occurrence is especially noticeable with recessed light fixtures that are installed into the ceiling above a shower because of the required tempered glass lens which will decrease air circulation inside the recessed light fixture enclosure resulting in a hotter light fixture.

Reducing the Size of the Lamp
- The remedy to stop a recessed light from going on and off is to install a light bulb with a lower wattage.
- EXAMPLE:
- If the light bulb is a 60 watt then replace it with an energy saving 56 watt bulb and this will typically take care of the problem.

Dave and Dan, that is true, but my situation is somehat different. Some of the low voltage lamps in the same switch turn on and others do not. After a while some will turn off and others will turn on. I think the device has gone haywire….
Same thing here too Oscar, Check to see if your neutral wire is good. See the reply to Allan.

Dave, I am experiencing the same problem of a recessed light turning on by itself when the switch is turned off. How can power get to the light if the switch is turned off?
Chris
Chris,
The light seems to be getting power from somewhere, therefore I would suggest checking to make sure the switch has been wired correctly.
