LED Recessed Lights: Types, Sizes and Packs
LED recessed lights are ceiling downlights that use LEDs, either in a slim canless wafer with a junction box or a retrofit light made for an existing can. Choose by ceiling fit, cutout size, light output, color options and how many fixtures the room needs.

LED recessed lights are ceiling downlights that use LEDs, either in a slim canless wafer with a junction box or a retrofit light made for an existing can. Choose by ceiling fit, cutout size, light output, color options and pack count.
A canless fixture can suit a shallow ceiling space or new opening, while a retrofit model works with a recessed can already in place. For more detail on the low-profile style, see our slim wafer lights guide.
What types of LED recessed lights are there?
The main types are canless wafer lights and retrofit lights for existing cans. The ceiling determines which type is practical, so start by checking whether a housing is already installed.
| Type | What it includes | Where it fits |
|---|---|---|
| Canless wafer | Slim LED panel and separate junction box | A new ceiling cutout or remodel without a traditional can |
| Retrofit | LED module or trim that connects to an existing can | A ceiling with recessed housings already installed |
| Gimbal or adjustable | A recessed fixture with an angled, movable light head | A spot where you want to direct light at an object or surface |
Canless fixtures use spring clips to hold the panel in the ceiling opening. The junction box connects to house wiring and sits above the ceiling, so check that the ceiling space and installation conditions suit the model.
Retrofit fixtures use the existing can as part of the setup. Check the can's size, socket and trim arrangement before choosing a replacement.
Our guide to LED retrofit lights for existing cans covers that type in more detail.
A gimbal model can aim light at a wall, artwork or work surface. Confirm that the model's aiming range suits the target.
How do you choose a recessed light size?
Choose a fixture size by measuring the ceiling opening and checking the cutout requirement, not by relying on the size name alone. The stated size often describes the general class of fixture rather than the exact hole diameter.
A 4 in model may suit a smaller opening and a more focused area. A 6 in model is common for broader general lighting, but the right choice depends on room layout, ceiling height and beam spread.
The Sunco 12 Pack 4 Inch Slim Dimmable is a 4 in canless option with a junction box and a stated output of 650 lumens.
Before buying, measure the existing hole from edge to edge. For a new opening, use the fixture's required cutout measurement and make a template, since fixtures in the same size class can differ.
See our recessed light sizes guide for a closer look at 3, 4, 5 and 6 in fixtures.
What should you know about brightness and color?
Compare lumens for light output and color temperature for the appearance of the light. Wattage tells you how much power a light uses, but it does not by itself tell you how bright the room will look.
Warm color temperatures, such as 2700K or 3000K, look more yellow. Higher settings, such as 4000K or 5000K, look cooler and whiter.
Selectable CCT lets you choose from several settings during installation.
The Amico 12 Pack 6 Inch Canless Wafer offers five settings from 2700K to 5000K and a stated output of 1050 lumens.
The Ensenior 24 Pack 6 Inch 5CCT also offers five settings from 2700K to 5000K, with a stated output of 1200 lumens.
These output figures help compare the models, but room brightness also depends on spacing, ceiling height, wall color and the surfaces the light needs to reach. Our recessed lighting lumens guide explains how to think about brightness.
How many lights should you buy?
Work out the layout before you choose a pack count. The room's dimensions, purpose and lighting plan determine how many fixtures you need, not the number of lights bundled together.
Mark proposed fixture locations on a room sketch. Keep spacing consistent where the ceiling allows, then consider separate task lighting over areas such as a counter or desk.
A 12 pack can suit a smaller project or a room with fewer fixtures. A 24 pack may fit a larger project or cover more than one area, if the layout calls for that many lights.
The Ensenior 24 Pack 6 Inch 5CCT gives you a 24-piece canless set. The Amico 24 Pack 5/6 Inch Retrofit is a 24-piece option for an existing-can setup.
Check whether the pack contains the parts you need. A canless fixture may include a junction box, while retrofit lights may include a base and connection parts.
Our recessed lighting kit guide explains what a kit can include.
What does dimmable mean?
A dimmable recessed light lets you lower its output when paired with a compatible dimmer. Check the light's stated dimming range and dimmer compatibility before changing a wall control.
The Sunco 4 in light dims from 100% to 10%. The Ensenior 6 in model dims from 5% to 100% and is compatible with most dimmers.
Compatibility can vary by dimmer model. If you want to keep an existing control, check that its type works with the chosen light.
Can you use recessed lights in a bathroom?
Some recessed lights are damp-rated and can be used in damp locations, but that does not mean they are waterproof. Check the fixture rating and local electrical requirements for the exact location, especially near a shower or other direct water exposure.
The Amico 6 in canless wafer and Ensenior 6 in canless model are damp-rated. Amico advises against installing its light where it will face direct spray or standing water.
Damp-rated and wet-rated are not interchangeable terms. Follow the product instructions and applicable electrical code for the ceiling location.
Which LED recessed light type fits your project?
Choose canless wafers for a new ceiling opening or a shallow space, and retrofit lights when a compatible recessed can is already installed. Then narrow the options by size, color settings, dimming, brightness and pack count.
For a straightforward 6 in canless project, compare the Amico 12 Pack and Ensenior 24 Pack by output and quantity. For an existing can, check whether the Amico retrofit's E26 base matches your setup.
If a smaller opening matters, the Sunco 4 in model is the size-specific option here.
For planning a complete room, use our recessed lighting layout guide to place fixtures before choosing the final pack. Pick the type that matches the ceiling first, then buy the count your layout needs.
Frequently asked questions
What are LED recessed lights?
LED recessed lights are ceiling fixtures that direct light down from an opening or housing in the ceiling. Canless wafer models use a slim panel and separate junction box, while retrofit models fit an existing recessed can.
The right kind depends on the ceiling and wiring already in place.
Are canless and retrofit recessed lights the same?
No. Canless lights use a slim fixture and junction box, so they can suit a new cutout where a full housing will not fit.
Retrofit lights replace a bulb or trim in an existing recessed can, often using a base that connects to the can's socket.
What size LED recessed light should I choose?
Choose a size that fits the ceiling opening and gives the spread of light you want. Common options include 3, 4, 5 and 6 in, but the fixture's cutout requirement can differ from its size name.
Measure the opening and check the required cutout before buying.
How many recessed lights come in a pack?
Pack counts vary by model, with options such as 6, 12 and 24 fixtures. Estimate the number of lights from your layout first, then compare pack counts and keep a small allowance for a future replacement if that suits your project.
What does 5CCT mean on a recessed light?
5CCT means you can select among five color temperatures, often ranging from warm white to cooler white. The available settings vary by model.
Set the color before installation if the switch is on the junction box, and choose one setting consistently across a room.
