You need to consider many factors. Beam angle: spot (narrow) vs flood (wide), and everything in between The wider the angle, the farther apart the spacing can be without creating dark spots on the wall Direct vs indirect light: is the light facing the wall, so the room is actually lit by light reflecting off the wall, or are the lights directly lighting ...

Unless there are other restrictions such as clearance to framing members or insulation or open space above them you can use them. "New construction" is when the framing is open and not covered by drywall*; the fixture is typically attached to a framing member. As opposed to "old work" which is where it's closed on both sides and you're going through a ...

PAR = Parabolic Aluminized Reflector. The number is the diameter of the bulb times 8, so divide by 8 to get its diameter. Thus, a PAR30 is a 3.75" diameter bulb. Our last house had PAR30 floods in track lighting in the living room (a style that was all the rage when the house was built in the 1980s). You can use them indoors. The quality of light you get ...

The 3" clearance clause is referring to clearance to insulation. However, no inspector will OK these if they are near insulation, even if you were to push it 3" away. If you are installing in an insulated space you must use IC (insulation-contact) rated cans. I've done this a couple times now (installed about 35 pots in my house) and it still takes me ...

If you've got insulation in the ceiling, you'll need to get IC (insulation contact) rated fixtures -- they're also known as closed-can. I have a small soffet built over my sink; if yours is similar, make sure that the fixture you select will fit. Other than that, don't exceed the wattage for the fixture and you'll be OK. EDIT: On second thoughts, use an ...

I have those exact cans and they are adjustable. Take out the bulb and remove the trim. Inside you will see two or three wing nuts. Loosen these and raise the level of base to the desired location. If the base is raised all the way up, then indeed your bulbs are too long for the trim you have selected. Also note that every trim adds a different depth as ...

According to this site: R20 bulbs have reflectors that direct light forward and produce more narrow soft-edged beam that is less precise than PAR20 bulbs. R20 bulbs also produce less shadow than PAR20 bulbs. PAR20 bulbs control light more precisely and produce more concentrated light than R20. Source: ...

IC or Insulated Ceiling or Insulation Contact are required for can lights that touch the insulation. You cannot use a non-IC can by moving or cutting the insulation back the 3 inches required to use a non-IC can. Inspectors see insulation and they expect to see the silver cans, which is what an IC can would look like. The airtight cans are designed to use ...

There really isn't any downside that I'm aware of. Bulbs are a concern, although that applies to any type of light: are they readily available? Can you get them from your local big box store, or do you have to resort to a speciality lighting store, though special order, or from some obscure site on the internet? Regardless of light size, providing the ...

Good question. Yes, it's likely that you have to replace everything. This is one of the downsides of recessed lighting... most of the time the wires from the service tie-in are contained inside a housing or inside of a conduit. It's not weird at all to have it be like that... there are very few can light fixtures where this is not the case (due to fire ...

Due to the lack of adequate answers, I decided to research the differences myself and provide an answer to the benefit of the community. PAR Type Lamps From a build quality and light control standpoint, PAR type lamps are generally considered superior. The explicit parabolic nature of the reflector means light is more precisely reflected directly out of ...

Cove or crown molding that is below (free from) the ceiling by 2-4 Inches will give a subdued look. I would place the strip on the wall just below the aperture of the molding (that slit exposed by lowering the molding). Some installations I've seen use a separate wall trim that angles the light strip up..IE attach a wooden strip behind and below the crown, ...

The fixtures you linked to are absolutely fine for new construction sheetrock ceilings. If you are going to use suspended acoustical tile then you will need a different model fixture that mounts directly to the tiles, not the floor joists. In either case, you can lamp them with CFL bulbs which will burn cooler, less electricity. The only disadvantage to ...

I personally would abandon them for something with better requirements - there's a reason that IKEA stuff is low in price, and that reason is compromises. For instance, the GORM shelving units are strong and flexible, but take a while to assemble and are kinda ugly. In this case it looks like the compromise is the required spacing. My guess is that the heat ...

To be truthful, I'm not sure about the exact model you are using, but several of the Halo recessed cans have adjustable sockets. Look up inside and determine if the socket assembly is fixed by a couple of thumb screws on a slide rail. If so you can loosen them and set the bulb socket deeper into the fixture. Usually a Par 30 bulb is perfect for these types ...

While this is not really a diy type question, I'll give it a go. First I take integrated as a screw-in self ballasted cfl and a non-integrated is a cfl with 2 or 4 pins made to go in a fixture designed for that lamp. To answer your first question about new construction, some states have laws saying you have to use the fluorescent ballasted fixtures (for ...

There are a number of variables you need to consider in order to space them correctly. First, how much light do you want? Brighter rooms require more lights. Related to this is the max wattage of your cans. You will need more 35W lights to achieve the same brightness you'd get with 50W cans. What type of spread (angle of light ) do the bulbs you plan on ...

There is a category of power tool called a multi-tool that is basically a very small saw usefull in cutting in tight spaces. After you cut the initial hole, this tool could be used to trim away the area in the uper section on an angle to make room for your retaining arms. The tools come in corded and cordless version, and at various price points. The ...

No, you should not have to replace both of the existing switches on each circuit. You won't be able to dim from both ends, of course. You just need a "3-Way LED Dimmer" and follow the appropriate wiring. Replace one of the switches (on each set of lights that have two switches) with the dimmer - the other switch will turn them on or off, at wherever the ...

Get something that works with a standard medium-base floodlight bulb. But when it comes to safety of heat dissipation and the load on the circuit and switch, don't assume the can will always have an efficient, low-heat LED or CFL. Build so the lighting is still safe to operate with nasty old EZ-Bake Edison bulbs. IMHO, LEDs and CFLs are both already ...

This happened to me. The socket had power but was not lighting up the bulb. It turned out that the center connector had been flattened by the old bulb and was not making connection to the center connection on the new bulb. Turned off the power and pulled the center connector down so that it was now well off the base of the bulb receptacle and hey presto all ...

That socket can be replaced. It has two tiny screws from the back side to hold it in. The trick here is to get the right socket and get one that is pre-wired with lengths of wire to feed down the 3/8" flex whip to the junction box on the light. I am looking for that same exact socket, in large numbers. Good luck

Most of the major lighting manufacturers are starting to produce LED spots and floods for can lighting - the only downside is they're not cheap. I've been seeing them at various home improvement centers for 60-100 dollars a bulb depending on the type and wattage. Sylvania LED flood @ Home Depot

I have fluorescent tube lights in my crawlspace (talk about low headroom..). There's two fixtures each with two bulbs, which adequately light an area about 20' x 10' (and 4' high). They're mounted so they are centered between joists, and the middle of the bulb is right at the bottom of the joist (so the bulb hangs down about 1/2" below). One of these was ...

You've got it. Just make sure that in the light fixtures you use all black in one connector, all white in the second and all bare wire in the third (from your hand-drawn wiring, it looks like that's how you plan to do it). That way, the lights are wired in parallel so that they both get the full mains voltage across them when you turn on the switch. Also ...

As pointed out by others, luminaires above or near a tub/shower must be "steam-proof" (rated for damp locations). This means the fixture will be sealed in some way, to prevent moisture from entering the housing and causing damage and/or an unsafe environment. NEC 2008 410.10 Luminaires in Specific Locations. (D) Bathtub and Shower Areas. No parts ...

As noted by Skaperen and Longneck in comments below, NEC requires using listed devices in accordance with manufacturer instructions. So if it says for ceilings, the code requires that you only use it in a ceiling. All of the can type recessed fixtures I have seen are described by their manufacturers as ceiling fixtures (but there may be versions out there ...

The symptom of the gap you have in all my experience with recess lights have been the rough in housing has room for deflection. As you push the trim in place, the rough in pushes up also under the tension of the lens going in and it stays pushed up until the lens bottoms out on the ceiling and is released. The housing relaxes back down and creates the gap. ...

Another thing to check is that the fixture is or is not rated for use in an insulated ceiling. If you have a one-story house and you're putting the cans into a ceiling above which is your insulated attic, the cans will be surrounded by attic insulation, and if they're not rated, a halogen or other incandescent light can cause excessive heat build-up which ...

I don't know if this fits your exact situation. The solutions to lighting rooms with low ceilings is often to use indirect lighting around the periphery of the room. There are many types of wall lighting available. Perhaps indirect lighting bounced off light-colored walls… or maybe lighting placed along the upper-most walls pointing upward to provide ...
