What makes up the price
Cost by size
National averages, before any local adjustment. Computed from the same model as the calculator above, so the two always agree.
| How many | Fixtures | Typical | Range |
|---|---|---|---|
| 2 fixtures | 2 | $295 | $240 to $365 |
| 3 fixtures | 3 | $380 | $310 to $470 |
| 4 fixtures | 4 | $465 | $385 to $575 |
| 5 fixtures | 5 | $550 | $455 to $675 |
| 7 fixtures | 7 | $725 | $600 to $900 |
Make a list before you call
One fixture is $210. Four are $465, which is $116 each.
That is not a discount anybody is choosing to give you — it is the shape of the job. A licensed electrician costs about $61 an hour loaded, the call-out is $45 before anything happens, and isolating the circuit, proving it dead and testing afterwards happens once per visit rather than once per fixture. After that, each fixture is three quarters of an hour.
| Fixtures on one visit | Total | Each |
|---|---|---|
| 1 | $210 | $210 |
| 4 | $465 | $116 |
So: walk the house first. The hall light you have been meaning to change, the two bedroom fittings, the bathroom one with the cracked glass — get them all on one ticket. This is the single most effective thing you can do about the price, and it is worth more than shopping three electricians.
The fixture is not in the price, and that is why quotes disagree
Every figure on this page is installation only. People choose their own light fittings, and they run from $25 for a flush mount to $2,000 for a chandelier — a wider spread than the labor by a long way.
Which creates the commonest confusion in this trade: one company quotes supply-and-fit, another quotes labor only, and they look hundreds of dollars apart while describing exactly the same work.
Ask directly: does this include the fixture? And if you are supplying it, say so when booking and have it on site, unboxed, before the electrician arrives. An electrician waiting while somebody opens packaging is being paid $61 an hour to watch.
Weight is the thing that fails
A standard ceiling box is rated for 50 pounds of static load. That covers almost every flush mount, pendant and small chandelier.
Past that, the fixture needs independent support — a fan-rated brace box, a bar hanger between joists, or blocking fixed to the structure. A heavy chandelier hung from a box that cannot take it does not usually fail on the day; it fails in a year or two, from the ceiling, onto whatever is below.
Three practical points:
- Check the fixture's weight before buying it, not after. It is on the box.
- Anything over 50 pounds should be discussed with the electrician before the day, because the fix may mean getting above the ceiling.
- A medallion or a canopy can cover an oversized or misplaced hole, which is often cheaper than patching a ceiling.
Old wiring is where a simple job stops being simple
If the house predates about 1985, a fixture swap can turn up three things worth knowing about in advance.
No ground wire. Older boxes often have only two conductors. Many modern fixtures require a ground, and the honest answers are either running a new cable, using a GFCI-protected arrangement where code allows it, or fitting a fixture listed for use without one. What is not an answer is connecting the ground to nothing and saying nothing.
60°C conductors against a 90°C fixture. This is the one almost nobody knows. Older cable is rated for 60°C at its terminations. A lot of modern enclosed LED fixtures are marked "use with 90°C supply conductors" because the driver sits in a sealed housing against the ceiling and gets hot. Putting one on 60°C wire is a real incompatibility, and the fix is either a different fixture or a short length of high-temperature cable back to a junction. A good electrician will spot the marking; a hurried one will not.
Cloth or brittle insulation. Insulation on mid-century wiring goes stiff and crumbles when disturbed. Sometimes the fix is a few inches of heat-shrink and care; sometimes it is a sign the circuit needs more attention than one fixture.
None of these is a reason not to change a fixture. All of them are reasons to mention the age of the house when you book.
Dimmers and LED
The most common complaint after an LED fixture goes in is buzzing or flicker at low brightness, and it is almost always a mismatch rather than a fault.
- The fixture must say dimmable. Many LED fittings are not, and dimming one that is not will shorten its life and may do it visibly.
- The dimmer must be LED-rated. An old rotary or slide dimmer designed for incandescent loads needs a minimum wattage to behave, and four LED fittings may not reach it. Replacing the dimmer with a modern LED-compatible one costs $25 to $45 and solves most of these complaints.
- Check the compatibility list. Dimmer manufacturers publish which fixtures they have tested. It is dull and it is the reliable way to avoid flicker.
If you are changing fixtures to LED anyway, change the dimmer at the same time. It is minutes of extra work while the electrician is already there.
Hanging heights worth knowing
Fixed once, awkward to change, and almost free to get right:
- Over a dining table: 30 to 36 inches from the table top to the bottom of the fixture. Measure from the table, not the floor.
- Over a kitchen island: 30 to 36 inches, and for multiple pendants space them evenly with the outer ones roughly in line with the counter ends.
- In a hallway or room: at least 7 feet of clearance underneath.
- In a two-story entry: the bottom of the fixture roughly level with the middle of the window from outside, and never lower than 7 feet above the floor below.
- In a bathroom: anything over a tub or shower must be rated for damp or wet locations, and there are clearance rules about how close a fixture can be. This is a code question, not a taste one.
What you are paying for
For four light fixtures into existing boxes, standard ceilings, at $465:
| Labor, about 3.75 hours | around $229 |
| Boxes, connectors and wire | around $72 |
| The call-out | $45 |
| Overhead and margin | the balance |
Labor is most of it, which is why the number of fixtures matters so much more than which fixtures they are. A $40 flush mount and a $400 pendant cost the same to hang.
Questions worth asking
- Does this include the fixtures, or is that my part?
- How old is the wiring here, and is there a ground at the boxes?
- Does this fixture need 90°C supply conductors? Check the label.
- How much does it weigh, and will the existing box take it?
- Is the dimmer LED-compatible, and should it be changed at the same time?
- For a bathroom: is this fixture rated for the location?
- Can we do all of these on one visit?
- What happens if a box is damaged or the hole is oversized?
- Is there a call-out fee, and is it included here?
Common questions
How much does it cost to install a light fixture?
About $116 each when four are done on one visit, or $210 for a single fixture on its own. The difference is not a discount — a licensed electrician is about $61 an hour loaded, the call-out is $45, and isolating the circuit and testing afterwards happens once per visit rather than once per fixture. Running wiring to a new spot takes a single fixture to about $335, and a new circuit from the panel to $485.
Does light fixture installation include the fixture?
Not in these figures, and that is the commonest reason two quotes look hundreds of dollars apart while describing the same work. People choose their own fittings, which run from $25 for a flush mount to $2,000 for a chandelier — a far wider spread than the labor. Ask each company directly whether the fixture is included. If you are supplying it, have it on site and unboxed before the electrician arrives, since waiting while somebody opens packaging costs $61 an hour.
How heavy a light fixture can a ceiling box hold?
A standard ceiling box is rated for 50 pounds of static load, which covers almost every flush mount, pendant and small chandelier. Past that the fixture needs independent support — a brace box, a bar hanger between joists, or blocking fixed to the structure. A heavy chandelier on an inadequate box rarely fails on the day; it fails a year or two later, from the ceiling. Check the fixture's weight before buying it, and mention anything over 50 pounds when booking.
What if there is no ground wire at the light box?
Common in houses built before about 1985, where boxes often have only two conductors. Many modern fixtures require a ground, and the legitimate answers are running a new cable, a GFCI-protected arrangement where code permits it, or choosing a fixture listed for use without a ground. What is not acceptable is connecting the ground to nothing and saying nothing about it. Mention the age of the house when booking so the electrician arrives expecting it.
What does "use with 90°C supply conductors" mean on a light fixture?
That the fixture needs wiring rated for higher temperature than older cable provides, and it is the incompatibility almost nobody knows about. Many modern enclosed LED fittings carry this marking because the driver sits in a sealed housing against the ceiling and runs hot, while cable in a pre-1985 house is typically rated 60°C at its terminations. The fix is a different fixture or a short run of high-temperature cable back to a junction. A good electrician spots the label; a hurried one does not.
Why do my LED lights buzz or flicker on a dimmer?
Almost always a mismatch rather than a fault. The fixture has to say dimmable — many LED fittings are not, and dimming one that is not shortens its life. The dimmer has to be LED-rated, because an old incandescent dimmer needs a minimum load that four LED fittings may not reach. Replacing it with a modern LED-compatible dimmer costs $25 to $45 and solves most of these complaints. Dimmer makers publish compatibility lists, which are dull and reliable.
How high should a light fixture hang over a dining table?
Thirty to 36 inches from the table top to the bottom of the fixture — measured from the table, not the floor. The same range works over a kitchen island, and with multiple pendants space them evenly with the outer ones roughly in line with the counter ends. Elsewhere, leave at least 7 feet of clearance underneath. In a two-story entry, aim for the bottom of the fixture roughly level with the middle of the window as seen from outside.
Can any light fixture go in a bathroom?
No. Anything over a tub or shower must be rated for damp or wet locations, and there are clearance rules about how close a fixture can be to the bathing area. That is a code question rather than a preference, and it is the kind of thing an inspector looks at. Tell the electrician where each fixture is going when you book — a vanity light and a shower light are different products and substituting one for the other is not a judgment call.
Is it cheaper to replace several light fixtures at once?
Substantially. One fixture is $210 and four are $116 each — the call-out and the circuit work happen once, and after that each fixture is about three quarters of an hour. At $61 an hour loaded for a licensed electrician, making a list and having everything done in one visit saves more than shopping three companies does. Walk the house before you call.
Can I install a light fixture myself?
It is within reach for a confident DIYer on a straight swap into an existing box where there is a ground, the fixture is light, and you can prove the circuit is dead with a tester rather than assuming. What should go to an electrician: anything heavy, anything in a bathroom near water, any house old enough to have no ground or brittle insulation, anything needing new wiring, and anything where the existing box is loose. Many jurisdictions also require a permit for new wiring, though not usually for a like-for-like swap.
What if the new fixture does not cover the old hole?
A ceiling medallion or an oversized canopy will usually cover it, and either is far cheaper than patching and repainting a ceiling. This comes up most when going from a large flush mount to a small pendant. Mention it when booking if you know the new fitting has a smaller base, because it is the sort of thing that is easy to bring along and awkward to discover halfway up a ladder.
Does changing a light fixture need a permit?
Usually not for a like-for-like replacement into an existing box — that is maintenance in most jurisdictions. Permits generally come into it once new wiring is run, a new circuit is added, or a box is relocated. Rules vary by city, and an electrician who works locally will know. Worth asking rather than assuming, particularly if several fixtures are being added where none existed.
