The Complete Guide to Choosing Between 6 Inch and 4 Inch Recessed Lights
When designing a lighting plan for any residential or commercial space, one of the most important decisions is choosing between 4 inch and 6 inch recessed lights. Recessed lighting is a popular choice to provide both task and ambient illumination in rooms of all sizes. Determining which size recessed light best suits your needs depends on factors like room dimensions, aesthetic preferences, energy efficiency goals, and budget.
We'll compare the light output, cost considerations, installation process, energy use, and ideal placement in various room sizes. With the information presented here, you'll be able to confidently select the best recessed lighting option for your unique space and lighting goals.
Size Difference Between 4 Inch and 6 Inch Recessed Lights
The most noticeable variation between 4 inch and 6 inch recessed lighting is the physical size of the light itself. As the names suggest, 4 inch recessed lights have a 4 inch diameter while 6 inch lights have a diameter of 6 inches.
In terms of appearance, 4 inch lights have a more minimalist, streamlined look that blends into the ceiling. The smaller size makes them ideal for inconspicuous accent lighting. 6 inch lights make more of a design statement with their larger diameter. They can create an elegant, consistent look when installed in groups.

When it comes to trim and baffle options, 4 inch lights generally offer greater flexibility including wall wash, adjustable gimbals, and optical systems for directing light. 6 inch lights are compatible with trim kits to customize the visible part of the fixture.
Light Output Comparison
The major difference in performance between 4 inch and 6 inch recessed lights boils down to brightness. Generally, 6 inch lights produce higher lumen levels, resulting in brighter, more powerful light.
With a larger surface area, 6 inch lights distribute illumination over a wider area with a broader beam spread. This makes them well-suited for lighting open concept great rooms and living spaces. 4 inch lights have lower lumen output and a more condensed lighting footprint. They work well for highlighting specific zones like workstations.
Both 4 inch and 6 inch recessed lights offer adjustable reflectors and gimbal rings to control light direction and achieve the desired ambiance. However, the beam angle options tend to be more limited with 4 inch lights.
Using 4 Inch Recessed Lights
If you're looking for task lighting or want to accent architectural details, 4 inch recessed lighting is likely the best choice. The smaller size makes these lights ideal for residential applications like illuminating artwork in hallways, adding mood lighting in bedrooms, and task lighting in home offices.
With 4 inch recessed lights, you can choose from various beam spreads including spot, narrow flood, flood, and wide flood. Narrower beam angles help target light to specific areas. The multitude of specialty trims also enhances their visual appeal and functionality.
Since 4 inch lights are smaller and typically require minimal wiring, the installation process tends to be quicker and less expensive compared to 6 inch fixtures. Just take care to position 4 inch lights properly so they don't create scalloped dark spots between fixtures.
Ideal Uses for 4 Inch Recessed Lighting
- Accent lighting
- Task lighting
- Under cabinet lighting
- Highlighting artwork
- Illuminating shelving
Using 6 Inch Recessed Lights
With higher lumen output and wider beam spreads, 6 inch recessed lights are well-suited for ambient lighting larger spaces. The increased brightness makes them a great choice for effectively illuminating living rooms, kitchens, dens, and other mid-sized to large rooms.
Many 6 inch recessed lights now come with convenient all-in-one pre-wired kits for easier and quicker installation. While the individual fixtures have a higher price tag than 4 inch lights, you may ultimately use fewer 6 inch lights to sufficiently light up a bigger area, which helps reduce costs.
Today's 6 inch recessed lights also provide greater energy efficiency. LED technology paired with smart dimmer switches helps conserve electricity.
Ideal Uses for 6 Inch Recessed Lighting
- Ambient lighting
- General lighting in kitchens
- Illuminating living rooms
- Lighting large closets
- High ceilings and vaulted ceilings
Energy Efficiency
When choosing between 4 inch and 6 inch recessed lighting, energy efficiency is another variable to consider. The good news is that both sizes are available with energy saving LED bulbs which use up to 90% less power than incandescent bulbs. LEDs also have exceptional longevity lasting up to 50,000 hours.
Dimmable 6 inch recessed lighting provides greater control over brightness levels, allowing you to further reduce energy consumption. With smart technology, LED dimmers can be adjusted from smartphones.
Keep in mind that the number of recessed lights needed can impact overall energy use. While 6 inch lights are individually more energy intensive, installing fewer of them may balance out costs in the end.
Cost Differences Between 4 and 6 Inch
In general, the initial purchase and installation costs are lower for 4 inch recessed lighting compared to 6 inch fixtures of the same quality. Individual 4 inch lights range from $10 to $30 depending on the housing, lamp, and features selected. Basic 6 inch recessed lights start around $25 and go up from there.
Labor accounts for a large portion of the total installation cost. The faster and simpler it is to install lights, the lower the price tag. Some 6 inch recessed kits come with pre-wired housings to streamline installation. Complex wiring and framing requirements can increase labor time and expenses.
To offset the higher individual cost of 6 inch lights, you may be able to use fewer total fixtures. The increased light output means wider spacing between lights which lowers the overall number needed.
Choosing Lighting for Different Room Sizes
The dimensions of a room should factor heavily into choosing between 4 inch and 6 inch recessed lighting. Here are some general guidelines on which works best in different room sizes:
- Small rooms under 75 square feet - 4 inch recessed lighting
- Mid-sized rooms 75-400 square feet - Mix of 4 inch and 6 inch
- Large open concept rooms over 400 square feet - Primarily 6 inch recessed lighting
For medium rooms like kitchens and dining areas, you can use 4 inch recessed lights over cabinets and counters while utilizing 6 inch lights for primary ceiling illumination. When mixing sizes, ensure the finishes and lamp color temperatures match.
To recap, the major differences between 4 inch and 6 inch recessed lighting comes down to physical size, brightness, beam spread, and usage scenarios. 4 inch recessed lights deliver lower lumen output from a smaller aperture, making them suitable for accent and task lighting in specific zones. 6 inch recessed lights produce higher lumen levels through a wider aperture to effectively illuminate mid-sized and large areas.
Additional variables like installation costs and energy efficiency should be factored into your recessed lighting selection. Determine where you need accent lighting versus overall ambient lighting when planning placement. With this guide's information on 4 inch and 6 inch recessed lights, you can choose the best option to meet your home's unique lighting needs.
