Hello,

I had receessed lighting installed in my exterior soffits and they look great. The only problem is there is some light leakage. Can anyone reccomend what type of material i should use to insulate the gaps? I've included a pic of one of the lights.

Thanks,
Tommy

I agree the airtight trim will solve the leak from the can.

However, on the comment about outside soffit lights, I am not an electrician but that was also what I was told by the inspector, because it's outside, we had the same requirements. I don't remember whether it had to be a trim rated for "DAMP" or "WET" locations, but we couldn't use any open trim.

I don't know if being in Miami where we have frequent storms and driving rain makes a difference.

Here is a picture of my outside soffit lights.

I could see that being considered a wet location as rain could hit the pitched soffet and run down into the trim. However, there is still no way for the water to get up in the fixture, and with those grooves, there isn't a way for a normal wet location trim to seal up the grooves, so I don't see what it accomplishes.

Many, many contractors, and unfortunately some inspectors, do not have as much of a clue as they should. Some still go by the "I was always told..." mentality.

More of them need to be questioned and asked for a code citation for things. Thing is most folks just take their word as gospel without question.

Most open trims ARE damp rated which is ALL you need for an outside installation.

This is the key word and I have to show few inspectors on that and they did not relized the change from UL ( USA side ) ou CE/NF ( France side )

The common open trim is listed in damp area so that is useally not a issue.

Somecase I use baffled trim as well so I can go either way.

Readers., Please note with glass trim they will really restrict the wattage so you will not get very bright light there at all.

Merci,
