Definitions
Downlight or recessed light - A type of light fixture that is installed in a recessed cavity in the ceiling.
Ceiling fixture - A type of light fixture that is mounted on the ceiling.
Recessed hole - A hole that is cut into the ceiling, typically for the purpose of installing a downlight.
Dimmable - A feature of some lighting fixtures that allows them to be adjusted to produce different levels of light output.
Lumens - A measure of the amount of light that is emitted by a light source.
LED - A type of lighting technology that uses semiconductor devices to generate light. LED lights are more energy-efficient and have a longer lifespan than traditional incandescent bulbs.
CRI - A measure of a light source's ability to render colors accurately. The higher the CRI, the better the light source is at rendering colors.
CCT - A measure of the color temperature of a light source. The higher the CRI, the cooler the light source is.
Wattage - A measure of the power consumption of a light source. The higher the wattage, the more power the light source consumes.
Voltage - The measure of the force that drives an electric current.
Downlight power
The power consumption of a downlight is measured in watts (W). The more watts a downlight uses, the more power it consumes. The power consumption of a downlight is affected by the type of light bulb used, the number of bulbs used, and the voltage of the electrical system.
The light output of a downlight is measured in lumens (lm). The more lumens a downlight produces, the brighter it is. The light output of a downlight is affected by the type of light bulb used, the number of bulbs used, the wattage of the light bulbs used, and the reflectivity of the surfaces around the downlight.
LED Downlight Output
| Wattage | Lumens | Application Scenarios |
| 2-3 watts | 110-240 | Lower watt downlights are often used for vehicle ceilings. They can be also in a limited space, where significant lighting fixture is not required. |
| 4-5 watts | 240-400 | Are used in damp locations. Can be used for different purposes and locations, including corridors, rooms, and halls. |
| 6-7 watts | 300-500 | Mostly used for general lighting and are great for residential lighting |
| 8-9 watts | 330-740 | Can be used in living rooms, shops, bedrooms, offices for general lighting purposes. These wattages are the most popular. |
| 10-13 watts | 850-1250 | Are often used for commercial lighting. Are perfect for patios, barns, etc. however can also be used for general lighting in some situations. |
| 13-25+ watts | 1250+ | Are perfect for properties with a high-ceiling. Can be used in hospitals, classrooms, warehouses, and for task lighting. |
Common downlights lumen ranges
The amount of light output required from a downlight depends on the purpose for which the downlight will be used.
300-700 Lumens - are great for general lighting in a room.
800-1200 Lumens - are better for task lighting, such as in a kitchen or bathroom.
1200-1600 Lumens - can be used for accent lighting, such as highlighting artwork or architecture.
1700 Lumens and up - are best for outdoor use, such as in a porch or garage.
The common color temperature of downlights
The color temperature of a light source is measured in Kelvin (K). The higher the Kelvin, the cooler the light source is.
2700K - is a warm white color temperature, and is often used in living rooms and bedrooms.
3000K - is a cool white color temperature, and is often used in kitchens and bathrooms.
4000K - is a daylight color temperature, and is often used in offices and task-oriented rooms.
5000K and up - is a super daylight or blueish color temperature, and is often used in outdoor lighting.
Introduction of downlight application scenarios
The installation of downlights can be a bit tricky and time-consuming, but the results are definitely worth it in the end. Here are some tips on where to install downlights and how many you'll need.
Living room:
The living room is often the largest and most used space in the house, so it's important to get the lighting right. Downlights are a great way to add ambient lighting to a room and can be installed around the perimeter of the room. For a more dramatic look, you can also install downlights in clusters of three or more.
Kitchen:
Downlights are also a great choice for the kitchen. They can be used to provide task lighting over the countertops and stove, and can also be installed under cabinets to provide accent lighting.
Bathroom:
Bathrooms are another room where downlights can be used to great effect. They can provide task lighting for the mirror and sink area, and can also be installed in the shower or bathtub area to provide accent lighting.
Bedroom:
Downlights can be used in the bedroom to provide ambient lighting or can be installed in clusters to provide accent lighting. They can also be used to light up a reading nook or sitting area.
Office:
Downlights are a great choice for the office, as they can provide task lighting for desks and work areas. They can also be used to highlight artwork or architectural features.
Outdoor:
Downlights can also be used outdoors to provide accent lighting for landscaping or to light up a patio or deck area. They can also be used to light up a driveway or walkway.
How many downlights do I need?
The number of downlights you'll need will depend on the size of the room and the purpose for which the downlights will be used.
For a small room, such as a bathroom or bedroom, you'll need two to four downlights.
For a medium-sized room, such as a living room or kitchen, you'll need four to eight downlights.
For a large room, such as an office or outdoor space, you'll need eight or more downlights.
Introduction of downlight models
There are a variety of downlight models available on the market, so it's important to choose the one that best fits your needs.
Recessed downlights:
Recessed downlights are the most popular type of downlight, as they're easy to install and provide a clean, finished look. Recessed downlights are available in a variety of sizes, styles, and finishes.
