DIY recessed fixture project
I'm going to be installing six new LED cans in my living room. Hopefully this picture gives you a good idea of what I'm trying to do. The paper cutouts are my templates for cutouts.

However, I'm planning on removing the light from the ceiling fan, and hopefully I can use that existing power source to wire in my cans from the attic.
I hope to run these lights off the existing switch at the door (pictured below). It's currently wired for an outdoor light on the right, a ceiling fan speed controller in the middle, and the ceiling light fan on the left.
I'd like to hook up all the cans to one dimmer, which will take the position of the existing ceiling light switch on the left. Then I'd like a replacement fan speed controller in the middle, and then keep the outdoor light switch on the right.



Is this something I should be able to do myself, or would I really need to call an electrician? Also, I was hoping the cords running to the ceiling fan would be individual (one for the light, one for the fan), but it appears to be just one single white cable.
If you guys have any advice or suggestions I would really appreciate it.

By removing the light from the fan you could feed the new down lights from that ,it appears that the red conductor could be used from the ceiling box to feed the new down lights,connect the dimmer where the switch with the red wire is now
Make sure the new cans are IC rated and use complete units from the same mfg.
I guess it depends on your level of your experience as to wether you can DYI, really not to difficult.

Is there attic above? If not it will be tough to do this without ceiling damage. Even with a long flexible drill bit, there is a long enough space between the lights to make it difficult to do without cutting into the ceiling.

There is a big attic above this ceiling, and the units I'm installing are IC-rated. I've already installed one can in a separate hallway, but this replaced an existing fixture, so that was much easier. Nonetheless, I'm confident I can get the cans in place, but I'm really unsure of how to wire them.
So if I use that (white) cord that's going to the ceiling fan now, am I going to have to splice it? Or do I run new cords (at the electrical twist caps) to my can lights? That's still the hangup that has me confused.

Running cords would be a code violation. You need to run cable.
You would temporarily remove the fan from its junction box to make work easy. The red of the 3-conductor cable coming in to the fan box will be used for your lights. You will run the new cable for the lights into the fan box and connect white to white and new cable black to red of the old cable in the fan box. When the fan goes back you can cap the fan blue since you are removing the fan light.
New cable will be run to the first light then from the first light to the second light and from the second light... well you get the idea.

God bless the Internet. I join this forum and half an hour later I'm all ready to go.
Thanks so much for the help. I'm a rookie to the DIY game so I'm sure I'll be posting all kinds of naive questions on this forum. I'll do my best to avoid those code violations!

Will having six downlights (recessed, not extending out of the baffle) mitigate the strobing effect?
I'm not sure how else I could appropriately place those cans.

If the fan blades impinge on the cone of light you will have some strobing.

You said you're a rookie to the DIY game. You just hit a grand slam home run.
It doesn't get much better than this. You can power and switch your new lights by only running cable in attic. This is an electrician's dream come true.

The blades are not directly below the cans. I'm not at home to take measurements or additional photos, but this angle might give you a better idea of what I'm currently planning.

I'd MUCH rather have six lights in this room, but perhaps I'm better with four, just so I can avoid any strobing? I just don't think that'll put out sufficient, even light.

Have you checked the mfg spec's for spacing? They usually suggest spacing with regard to ceiling hgt.etc.

Thanks for all the help, guys. The wiring advice you gave me was fantastic, and everything works perfectly. FWIW, I went with the Philips Warm Glow LEDs, and I like them a lot. No buzzing or flickering whatsoever.
Thanks again!

Thanks again!

Quick follow-up question: is running ROMEX off the red wire from the fan light to my new can lights a code violation?
Also, I've been told by a guy with real estate experience that I really need to get permits. If this is true, should I go ahead and do the other rooms this way first? Or am I going to get fined for not getting the go-ahead in advance?

I don't want to review entire thread. It was decided I think to take neutral off of ceiling box, and red off ceiling box, switching red. This is perfect and in no way a code violation.
I might get blasted here, but I personally would not get a permit to add lights to my home.
Permits are good and helpful, I don't agree one is needed in this case.

IME, the permit is supposed to be pulled before the work starts, but I have started and then gotten the permit. Some areas want permits for everything, others set a certain dollar amount. Since all the work is retrofit there really is nothing to see before the work starts. It would only be a final inspection.

Thanks again for all the help, guys. Since the initial post, I have now installed recessed lighting in another room and a hallway - 13 cans in all. They work perfectly, and I couldn't have done it without your advice.
A new question, though: what if I were to install these in a house with no existing ceiling light? My sister wants help installing these in her living room, but she has no existing lighting for that in place. Could I run new wire from an existing switch (where the porch light currently is, for example)? I'd assume I'd need a bigger electrical box/plate there, but would I need to run anything new from the fuse box?

Whether you can add to an existing circuit dependent on how heavily loaded the circuit already is and the amount of the new load. Some circuits cannot have lighting on them.

I'll get my sister to send me a pic soon, but the circuit I think she wants to use is already running a porch light. If we were to change that to an LED bulb, and use 6-8 recessed LEDs (so about 100W total max), would the existing wiring be able to handle that kind of load?
I'll post pics as soon as I receive them.

nice work (below)!
WRT your sister: I just added a light where there was no overhead wiring. I tapped off a recepticle and ran a second cable to a new switch location. Wasnt hard
Not sure if that makes sense with out a diagram. Im at work now, so I dont have the time to sketch anything...

- one cable from outlet to fixture, spliced black to black / white to white on outlet side; connected white to fixture (neutral)
- For the line side, (black at the fixture)... I connected the BLACK on the first cable to WHITE on the cable the I ran to the switch--I colored white black to indicate power. At the switch, I then connected the colored-in white to the switch top, connected black on this 2nd cable to the bottom of the switch and then connected--at the fixture--the black from this 2nd cable to the fixture.

Okay, here's the current setup.

You can see the outlet/switch on the left side of the front door.
It looks like this:

The two horizontal switches on the right are for outdoor security lighting. The middle switch is for the entry light seen in the picture above. The left switch is a complete mystery. It doesn't appear to control anything, not even activation of wall outlets. So that's the one we're hoping to use for her recessed lights.
I asked her to pull the switches out for a better look, and this is what we're dealing with:



I assume that hunting down the mystery of the left switch will involve some potentially destructive adventuring, right? Am I okay to just forget about that, considering it's an old house?
Should I get a new electrical box/receptacle there? I understand I have to run romex down the wall there from the attic, but I'm not sure how to tie it in.
Thanks so much again for all of your advice.

Also, I forgot to mention: she has a 15 amp circuit there, so I guess that's 1800W max load? Unfortunately she has a bunch of lights already connected to it (closet lighting, bedroom overhead and outlets, along with the previously mentioned entry and security lighting). If we switch the majority of those to LED, however, it shouldn't be a problem with regard to exceeding 1800W.
#31
Technically the U.S. code does not have a limit on the number of lights per circuit. It is more common sense. Not all lights will be on at the same time. I'd just do it. If you have problems you can move the receptacles to their own circuit. You have power in at the switch box so adding the lights is easy. If you wanted to keep the mystery switch you could even use another duplex switch but I'd say just cap the lead to the mystery load.

Okay, so I can cap the mystery lead. I assume I should pull the receptacle box out in order to get the romex fished down from the attic. Is the end at the switch just pushed through the back of the receptacle and wired in? Haven't done anything like that before.
Also, should I go back to black, white to white, and copper to ground on this - like I did before? The previous post about a different wiring scheme threw me off.

Terminology: When used for switches it is usually called a switch box when it has switches.

All right, so at the "new old work box" I'll go black cable to the switch, white cable to the group of whites, and ground to the switch or the group of grounds?
Also, at the fixtures, everything goes like before, right? (white to white, black to black, and ground to ground)
Thanks again for your help and apologies for the questions. The thought of burning down my sister's house gives me pause.

This is how it looks now with the old work box put in. Again, I'm not entirely sure on which cables go to what, or which cable is the power source. The ones on the right (already hooked up to the other switches) go to the outdoor porch and entry lights, and the new fresh romex in white will go to the recessed cans. If in doubt, should I just cap those wires together?
Also, just to be sure, I'm only going to have a single black wire connected to my new dimmer switch (from the romex)?
#38
The black wire that was daisy chained to all three switches is your hot. For me pigtaling is easier. I'd cut the hot wire back to the first bare spot and add three pigtails. Run one pigtail to each switch.

Do you mean to just pigtail all the black wires from the wall, along with three short black wires, one to each switch?
I still don't know which one is the hot. I can't go back and find that one that was daisy chained to everything previously, as I disconnected it all when putting in the old work box.
