I recently saw 5-inch remodel non-IC cans made by Commercial Electric (model K3) at Home Depot. The can has a 75W max R20 bulb rating and is UL stamped. The junction box is located on top of the can rather than on an extended arm (like the Halo cans). Is this a safety issue? Is Commercial Electric a reliable brand? By the way the K3 costs ~1/4 of a Halo of the same size. Your input is very much appreciated !!

Commercial Electric is a brand name for the store your buying them from. If it the same recessed light that I am picturing I wouldn't use them if the store offered to pay me to take them off the shelves. I don't think the junction box is listed for feed thru wiring which means you can only have 1 cable in each light. How does it mount? As I remember there is a metal plate the goes above the ceiling that connects to the housing. The Halo as well as many other brands have spring clips that are very easy to install. The trim is included right? What if you want something different? I don't think you can buy trims for these housings. You get what you pay for. Use the Halo or other name brand.
I used them once several years ago and wasn't comfortable with the design. Also, as caselec said there is a question about feed-through wiring. BTW, I find 410.11 somewhat ambiguous in that it seems to permit feed-through wiring if the the fixtures are operating together, even if not identified as such. Does this restriction only pertain to wiring on a different part of the lighting circuit?
We won't install a Commercial Electric can. If a customer buys them, we tell them to take them back and buy Halo. When we supply cans, which is 99% of the time, we use Halo or Juno. Sometimes we will use the Commercial Electric trims with a Halo can. There are many reasons, mostly being quality. The fit and finish doesn't come to my standards and it makes us look bad if the job looks sloppy.
I will explain the difference between the good can(Juno,lightolier)and not so good can(halo,commercial)and most of the time clients will pay more to go with the best quality. And if it is a cheap customer which only wants cheap cans i will not do the job because i know i will be the person after six months to be blamed after when the cans are not working properly. The customer pays for the material explain the goods and bads so you will not look bad later on. Because they will say abc electric installed it and it does not work.They will not say that i have picked the cans. there goes your reputation.
Just curious -- what temperature rating is required for terminating in the box? Since romex is rated 90C only for ampacity derating purposes, it can't be used in a box that requires 90C wires, which I'm supposing is the case for the type of box location you described, 2bz2p.
By the way, there is movement afoot to require recessed lights to be sealed against drafts when recessed cans are installed in places where it is difficult to install adequate insulation above the fixture -- like in vaulted ceiling areas. I guess there are some can lights on the market which don't have open adjustment slots (which result in convection drafts through the fixture), but I haven't seen them yet. Anybody used these types of fixtures yet?
