I have three Halo 4″ recessed lights (non-IC) that I’ve installed in a soffit. There is no insulation inside the soffit. The problem is that two of the cans cut in and out on their own. It’s not a short- it is very abrupt, like it’s a heat protection circuit or something. The thing is, there can’t be a heat problem- the soffit isn’t enclosed yet, and the room is 60 degrees. Any idea what is going on?
Thanks.

Does the wattage and type of bulb match the trims you've got installed in those cans. The label up on the inside of the can (at least in the larger housings) lists the proper combo's.

Too high wattage bulbs maybe? Room temperature wont matter much.
put in a much lower wattage bulb to test the thermal plan or go in there and see if the electrical connections are mechanically tight or see if the center tab in the bulb socket needs to be lifted / rasied to make a better contact with the bulb...

Hi Oldsaw,
I simply have to ask...the 2 can lights that keep cutting in and out...are they wired on a different circuit from the other can lights?
I know this sounds pretty dumb, but Iv'e seen it happen before ( like the song says: "Don't ask me how I know...I just do."), sometimes in remodeling, lights borrow a feed from an existing circuit.
It's quite possible that the circuit has an active switch or two on that line that somehow got overlooked when tying into it for the can lighting.....whereby said lights could accidently be controlled by someone in another room whom inadvertantly is turning the switch on or off.
I know this sounds dumb...overheating is definately a more likely cause, but hey, just thought I'd help you cover all the bases in tracking down the problem.
Good luck on your investigation/determination.
Please report back and let us all know what you find.
Thanks.

Its the kind of bulb and wattage you have in...I just went through this myself and once I chaged bulbs to the correct style and wattage....viola! no more disco tech!
the limitations of bulb type/wattage should be on the inside of the can...if not, the box they came in..if not the store you purchased them...if not..call them directly...if they don't know, tear everyting out and hang 2 highpowered flashlights
good luck!

Well, I'm embarassed to admit it, but it was the lightbulbs. Although the cans themselves are rated to 60W, the trim restricts it to 40W. Geez, pretty sensitive little things.... What ever happened to overengineering?"Honey, will you please make some sawdust and track it across the carpet?"
