Hello,
I am trying to add flood lights to the back of my two story house. I want to put one in each corner of the house. I have never really done any electrical work except wire a TV behind my living room wall. So I kinda need step by step directions on how to wire it, can I piggy back off of electrical that is already in the attic? I want the switch on the wall downstairs, can I just run the wire from the second story attic to the downstairs exterior wall? I know there will be extra insulation in there making it more difficult, but I can do it.
Thanks in advance for any help!

1. Your first challange will be to search the attic for an accessible 120 volt power source. A pull chain light fixture maybe?? An existing junction box???

You can tie into and existing cable but you have to know exactly where it comes from, goes to. You may also need to install two junction boxes if there isn't sufficient slack in the cable.

Also, an overhead light fixture in an upstairs room may have a hot (unswitched) circuit in it. Pull off a switch cover and look at the wiring. If a switch has only two wires (black and white) you can tap into that light fixture box to get your power.

2. Find a path between the power source and the switch location.

3. Run a 2 wire w/ground cable from the power source to the switch.

4. Run the same type of cable to each light or to one, then the other.

Wiring instructions to follow., depending on what you find for the power source.

I agree with 220/221 (whatever it takes) that figuring out where the power will come from and how you will lay out the wiring if the first thing to do.

Running a wire from the attic of a two story house to a switch on the first floor could be another challenge. If I'm understanding what you want to do, you will have to drill a hole from the attic through the top of the wall on the second floor, then drill another hole at the bottom of the wall on the second floor into the top of the wall on the first floor. Easiest way is to cut a hole in the bottom of the wall on the second floor directly above the spot where you want the switch to be on the first floor. If the wall is sheet rock, that may not be a big deal.

If you have fiberglass inslustion, your drill bit will wind it up like cotton candy as soon as it hits it, so be careful.

Would a motion activated light fixture work for what you are trying to do? I would look for a receptacle in an inside bedroom etc. that is on the second floor and fish off that receptacle for your exterior light fixture. Cut in an exterior box in the same stud bay as the interior receptacle and there is your power. If going upstairs to turn on the exterior floods isnt an issue then fish up the wall from the interior receptacle to a cut in switch then fromm there to the light.

Make sense?

Ok, I know I have a non switched light fixture near to that side of the house that I can probably tie into. Now, I see that it probably won't be as easy as sticking my fish line through the attic to the first floor(I kinda forgot that they may want to put plywood or drywall between the floors...) So now I'm looking at putting the switch upstairs. It won't bother me too much, it will just be annoying for the next owners, but they won't know it until after they get in the house.

What I want to do is make that "non-switched light fixture" into a switched light fixture and have another switch on there for my flood light. Currently I am speaking about putting this in the master. My non-switched light fixture is my ceiling fan and I always have to get on the bed to turn it on, so I would rather just flick a switch. The switch that is in there currently controls an outlet. can I turn it into a triple switch that controls the flood light, the outlet, and the ceiling fan? I wouldn't mind taking the power of controlling the outlet away since that is more annoying than anything.

So I have the spots that I want to put the flood lights, I know where I want the switch. Now how do I do it? Do I cut off the power before it gets to the ceiling fan and then split it to the switches and back up into the attic to the flood lights and ceiling fan? What kind of wire do I need to buy? Any other materials? How do you connect the spliced wires? Are simple wire nuts acceptable in the attic?

I have done almost everything else to this house, its time for me to learn some electrical!

Thanks for all the replies so far and into the future, I don't know how I would get anything accomplished if it wasn't for this site.

Man, you went from adding two flood lights to ceiling fan, receptacle,switching,triple,material, jumping on bed........

Narrow it down a wee bit to just the flood lights at this point and maybe we can help. You more than likely need some 14-2, retrofit boxes and at least a little bit of know how on electrical. So many variables, hard to say without seeing.

BTW, they have remotes that you can add to your ceiling fan so you dont have to add a switch if that helps.

You can do these things all together but spefic instruction will require specic information from you.

1. Remove the switch and see what kind of box is there and how many wires/cables are in it.


2. Take down the ceiling fan canopy and see how many wires there are in the jbox.

3. How much working space do you have in the attic above the switch?

4. Are you lights going to be mounted on a gable end or under the eaves?

I know...I just thought it would be easier to knock out both problems at once....I was out of town this past weekend so I haven't had a chance to look at it.

The electrical from the switch goes straight up into an open part of an attic where I have plenty of space. The only parts that I will have trouble working around is where I put the flood lights. It is a little cramped...everyother part is spacious and allows me to move freely.

I will plan on taking a look at the switch and the Ceiling fan in the next couple of days.

My flood lights will be under the eaves on each end of the house. So two floodlights total.

Getting cable to the lights should be the easy part. Drill a hole in the bird board (the blocking between the rafters) and push a 10' piece of fish tape in (from outside) with the cable taped to it. That way you won't have to crawl back into the tight space.


Stub plenty of wire out and sleeve it with non metallic flex and run it into a weatherproof jbox (probably round to accomodate your fixtures). Note: this is a technical violation unless you use UF cable as opposed to NM. Personally, I wouldn't hesitate for a second to do use NM.

There may be room in the existing hole in the top plate above the switch. Otherwise you will need to drill a new 3/4 to 1" hole.

Ok, I finally did my research and looked around in my attic and made a trip to the depot. There is two lines going down to my one switch in my master. I'm assuming one is the "hot" wire and the other goes to the outlet in the wall. I didn't go as far as to take everything apart in the outlet to check since it was fairly obvious.

Since I have this "hot" can I simply run everything(ceiling fan, outlet, flood lights) off of that? So I will have three switches in my master.

My plan is to first drill the holes and install the flood lights with wires coming out into the attic. I bought the 12 dollar flood light kit from Home depot...I also bought 100 ft of NM cable(the cheaper stuff 19.99 vs. 38.99) The guy at home depot said the cheaper stuff was fine for what I would be doing.

Once everything is installed, I will have the two flood lights attached by the electrical wire and one of the floodlights will be ran to the switch. I was thinking where you have the lights connected to the wire, there would be one that would be the hub for the other so the last one on the line will only have the one wire from the first flood light and the first flood light would have two, one from the switch and the other one going to the next flood light. Is this the best way to do it? Or should I run a line from the switch to each separate flood light?

Now the Ceiling fan with the "hot" wire already attached. Can I simply cut the wire, run it down to the switch and just tape the end of the "hot" wire?

How about connections in an attic, do you simply use wire nuts? Do you tape it up with electrical tape when you are done? I'm asking just to make sure I'm not doing anything wrong where it might cause a fire.

220/221: what does "sleeve it with non metallic flex" mean? Is this inside the attic or outside? I tried looking for it at home depot, but couldn't find it...I didn't ask though.

Thanks for all the help with this project!

Shopping last weekend at Sam's Club, I saw solar powered (to keep an internal battery charged) LED motion detector flood lights. Maybe an option, no electrical wiring needed.

Mike-

In my experience, these are junk. I would not recommend them to anyone. Just one opinion, however.

Slow down Skippy :laughing:

One thing we don't do is assume.

You need to spend two minutes and take care of steps 1 and 2.

1. Remove the switch and see what kind of box is there and how many wires/cables are in it.

2 minutes


2. Take down the ceiling fan canopy and see how many wires there are in the jbox.

3 minutes


Once everything is installed, I will have the two flood lights attached by the electrical wire and one of the floodlights will be ran to the switch. I was thinking where you have the lights connected to the wire, there would be one that would be the hub for the other so the last one on the line will only have the one wire from the first flood light and the first flood light would have two, one from the switch and the other one going to the next flood light.
OK. I will pretend you didn't just write this. Can YOU even decipher it?:jester:


Just do steps 1 and two and I will tell you exactly, step by step, what to do.:thumbup: I don't want to lay this out and have to redo it when I find out new info.

EDIT****I had written some step by step stuff here but then realized that I forgot that you wanted your fan switched. To complete this I will need you to take a look at you fan and switch wiring. The basics are here but there are a few details missing. I will add them later.****


If you have only two wires (one black, one white) go to bottom.


If you have more than two wires in your switch box (one black/one white), you have constant 120V power there and you can install your floodlight switch in that location.

1. Take apart and separate wiring and use a voltage tester (black to white) to find which wire/cable is hot. Identify this wire

2. Poke a skinny screwdriver next to the sw box to see what side the stud is on. Poke to the side away from the stud to help see if you have room for a 2 or 3 gang box.

3. Turn off power and remove box. Cut the opening larger to help you accomplish this. Dont cut it to it's final full width yet. Stay within thetop and bottom planes so you don't need to patch. If the box is side nailed, removal will be easy. Pry the box away from the stud with a flat screwdriver being careful not to damage the drywayy on the stud side.

If for some reason the box is nailed to the face of the stud, you can attempt to sawzall it out or just cut/patch the drywall.

4 Once the box is out, line your new plastic box up with the stud, mark it accurately and cut the opening. You now have some room to get your hand up in the wall.

5. Go outside to the furthest light and drill a 1" hole in the birdboard where you want the wire to come out. If you just want exposed cable to come out, drill a smaller hole, 1/2 minimum. Securely tape your cable to a piece of fish tape at least 10' long (so you don't have to crawl back into the pitch). Push the fish into the attic as far as you can (it's nice to have two people for this part). Once you get ahold of the fish/cable, you can pull it over towards the first light.

6. Go outside to the second light and drill the hole. This is where you have to make a call. You can either run both cables into the switch box or you can run from the sw box to one light, then the other. If you want to run from one to the other, use you head and figure out an easy way to do it in onwe shot. It may be easier just to run two separate cables.

7. Above the switch you will probably have to drill a new hole. Make sure you drill it in the same chase as the sw box is in. Typically the existing holes are driled close to a stud so be aware. DONT damage the existing wires :jester:

8. Push the wires down the wall and pull them out of the sw box hole.

9. Install the floodlights

10. Slip the wires into the new sw box, slide it into the hole and secure it with drywall screws. Be patient and get it flush and plumb.

11. Make up wiring, Strip sheath cleanly leaving about 8" to work with.

Separate blacks, whites and grounds.
Wirenut grounds together leaving pigtails for each switch. Tuck into box..

Wirenut whites tightly together, tuck into box.

Install pigtails (short pieces of wire) onto the HOT wire that you identified earlier. These will provide power to your switches.

Bottom. This is a whole 'nother set of instruction. I will include them if necessary.
