    I was told that black powder coated 4" recessed can lights are not suitable for bathroom settings(HD guy) but said the white coated versions are? Is there any truth to this, I say no.
    Another question is, are there 4" recessed lights(remodel versions that mount through the hole) that allow insulation to tough? Most I see are 3" min.

    thanks

    I've seen IC rated recessed, but not in remodel configurations. SOmebody may make them, but since they need to be bigger, I'm not sure how you'd get them through the hole. While somewhat of a pain, it may be better to cut a hole in the ceiling, install the new IC (and preferable AT) unit, then patch the ceiling. My preference would be to also make it air tight (AT), otherwise, you may be putting a bunch of vapor up into the insulation, and getting things wet.

    I agree with Jim, go with IC and AT, if you have attic above (and room) you could install from above. As to the color of the trim kit, personal preference.

    The recessed lights are pretty common at HD/Lowes etc. Lite On is what comes to mind, dont have one in front of me.
    Basically its a can with a arm that leads to a wire box. Its meant to push up thorugh a round hole and has clips in the can to secure to sheetrock.
    I was told and written on the can these need 3" clearance from insulation, so I was tryign to find if there is such a remodel can that can touch insulation?

    In the bathroom, pretty much all over replacing larger 6" cans.

    Once again "the guy at Home Depo" is WRONG!
    The can does NOT care where it is installed.




    I don't know of a true 4" can (for an R20/PAR20 lamp) that is old work and IC rated. Although I don't get out much and deal with Halo and Lightolier mainly.
    Lightolier's Lytening series is both IC and non-IC in the same can. The trim selection and installation determine which applies. They do have a 5" size.

    I don't think the can itself matters, but the trim kits do matter -- some are rated for showers, etc., some aren't. If the bulb is exposed, it's certainly not a good idea to put it in a shower.

    While there are trim kits for wet locations, the can itself will be rated for either IC of AT (insulation contact or air tight). Regardless of the trim, some moisture vapor is likely to get into the can. If it is AT, then it won't migrate into the insulation and being IC rated, likley hot enough so that the dew point will be quite high, meaning it is less likely to condense in the first place. A can that is not AT is designed so that it has air exchange, partly for cooling purposes, to limit the temperature rise, and is likely to be be coupled with a can that is probably not rated for IC - that air has to come from someplace.

    thanks everyone. I used the 4" recessed and pulled the insulation away to the 3". The insualtion is on rolls(paper backed) and didnt have too mnay ideas on how to get the insualtion away, I ended up using 1x2 to prop the insulation away and secured it. I hope thios isnt a no-no?

    It has been a while since this question we asked. Sorry if this has since been answered, but I am search challenged...

    Has anything changed? Is anybody offering 4" IC rated recessed lighting remodel housings yet? Has anybody come up with a clever little pop in spacer suitable for blown insulation.

    TIA

    4" can In bath

    Sure you can use any size recessed light in your bathroom but I don't know of any 4" remodeler, non-ic or ic that has a shower trim!
