Obstructions in the way of recessed can lights

I'm trying to install some recessed lights above my kitchen counters and found I have two potential obstructions: two Romex wires and a PVC pipe.



I did some measuring and discovered that the PVC pipe is in far enough that it won't interfere with the 6" can, but the can will definitely be within 1" of the pipe. I'm concerned that the heat from the light bulb might melt the pipe.

There's enough slack in the Romex that I could push them to the side, but once I slide the can in they will be touching the can. I'm guessing that's a no-no; is it?

Is there anything that I can do to install the can light in this location without creating a hazard? My can has "IC22R" on the barcode label; I don't know if that means that it has the IC rating that doesn't require 3" of air space around the light.

I cannot move the hole without totally messing up my lighting plan. If I cannot install the light at this very spot then I have to repair the hole and scrap the whole plan. But I'd rather scrap the plan than burn down my house.

I'd appreciate any advice you can offer. Thanks!

Never mind. Got an answer elsewhere. I've got to scrap the plan.

What was your reasons for that decision? Using IC cans and if necessary moving the pipe over with two pair of 45°ells a few inches apart. I'm assuming pipe is water.

I think the pipe is either a vent pipe for the sewer system or the main drain pipe for the master bathroom sinks.

The electrical wires are the larger factor for my decision. I spoke to an electrician and confirmed that those wires must not touch the can. I would have to reroute them, but I don't know where they both go.

I'm pretty sure that the yellow wire is the 12/2 for my bathroom circuit and I can follow that, but I don't know about the white one; I don't even know what circuit owns it. I'm also totally inexperienced with wire fishing.

I did some looking around with a flashlight and mirror up there to learn what I could about what's behind my ceiling. The other two locations are totally clear, but this one is smack dab in the middle of wires and pipes. Interestingly enough I cut this hole in the area of least obstruction; there are wires to my left and pipes to the right.

I think that I'm going to just have to find some other lighting solution. I really don't want track lights; I'm not sure at the moment what my other options are.

opt for smaller down lights

use smaller lights
4" incadescents or 4" mr 16 based lights

you have a bit more space to work with

Ray2047 said to add a couple of pieces to the pipe to re-route it around the can.

You can do the same thing with the 120v cable that passes the can. Add two junction boxes (that must remain accessible) and splice in an extension.

You said originally there was some slack in the wires. If you use IC cans you may be able to put a piece of fiberglass insulation board such as used to construct ducts between the lights and the cables.

I got some good news; I talked to a lighting specialist and he recommended a better placement for the light and there's no obstructions there. My design was flawed; this problem prevented me from making an even bigger mistake. Thanks everyone for your advice.
