What Are Wattage, Lumens, Illuminance, And Color Temperature?
Wattage:
Wattage refers to the power consumption of a light bulb or light fixture. With the prevalence of LED technology, wattage is no longer the primary indicator of brightness, the brightness of a light fixture depends on its efficiency.
A watt (symbolized W) is the standard unit of power or radiant flux in the International System of Units (SI). It is derived from the SI base units kilogram (kg), meter (m) and second (s), all of which are constructed from the standard’s defining constants. The watt is a measure of the rate of energy transfer over a unit of time, with one watt equal to one joule (J) per second. When applied to electromagnetic energy, the watt refers to the rate at which energy is radiated, absorbed, or dissipated.
Lumen(Luminous Flux):
Lumen measures The total amount of light emitted by a light source in a unit of time. A higher lumen indicates brighter light output.

Illuminance(Lux):
The brightness of the light falling on a certain area illuminated by the light source. Illuminance is the ratio of luminous flux to the area of the illuminated surface.

Color Temperature(Kelvin):
The color temperature is defined as the ‘temperature of the black body when same color light as that light is radiated by the perfectly black body’ and its unit is K (Kelvin). It shows the relative strength of violet light and red light of a color emitted light source.
Color temperature is a term for how warm (yellow) or cool (blue) the color of light emitted from a light source or light fixture appears. The scale commonly ranges from 2700K to 6500K. Lower color temperatures, around 2700K to 3000K, produce warm, yellow tones resembling the soft glow of candlelight. On the other end, higher color temperatures, around 5000K to 6500K, emit cool, blue-white light similar to daylight. For home lighting, color temperatures between 2700K and 4000K are commonly preferred.

Understanding these basic concepts will help in making informed decisions when selecting lighting fixtures for your home.

Recommended Lighting Levels For Residential Spaces/Home Lighting
Living Room Lighting Fixture Recommendations And Design Examples
The living room is the heart of a home, where people gather to relax and entertain. It requires a combination of general and accent lighting, here are some recommended light fixtures:
Chandeliers: Several factors need to be considered before installing the chandelier. If you don’t have enough natural light, or the height of the ceiling is over 3 meters, then hanging a statement chandelier in the center of the living room to provide general lighting and add visual interest would be a good choice.
Wall Lights: Install wall lights as accent lighting or functional lighting to create a soft glow and enhance the room’s cozy atmosphere.
Floor Lamps: Place floor lamps strategically in dark corners to supplement general lighting and create cozy reading nooks.
Of course, home lighting design without the main light has become a trend in interior design. Nowadays, lots of interior designers tend to use recessed downlights instead of chandeliers to provide the general lighting in the living room.
Dining Room Lighting Fixture Recommendations And Design Examples
The dining room is a place for gathering and sharing meals with loved ones. When it comes to dining room lighting, striking the right balance between functionality and aesthetics is crucial. It requires warm and inviting lighting, here are some recommended light fixtures:
- Pendant Lights: Pendant lights are a popular choice for dining rooms, as they provide focused task lighting while also adding a decorative element to the space. Opting for pendant lights with adjustable height allows for flexibility in lighting intensity and ambiance.
- Recessed Downlights: Recessed downlights offer a clean and minimalist look while evenly illuminating the dining area without overwhelming diners.
- Chandeliers: For a touch of elegance and sophistication, consider installing a chandelier above the dining table. Chandeliers come in a variety of styles, from traditional crystal designs to modern and minimalist fixtures, allowing you to choose one that complements your dining room decor.
Kitchen Lighting Fixture Recommendations And Design Examples
The kitchen is a multifunctional space that requires both task-oriented and general lighting, here are some recommended light fixtures:
- Under-Cabinet Lighting: Illuminate countertops and create a visually appealing ambiance with under-cabinet lights. LED strip lights or cabinet lights installed beneath cabinets provide task lighting for chopping, slicing, and meal preparation. These lights not only enhance functionality but also add a touch of sophistication to your kitchen decor.
- Pendant Lights Over the Island: Hang stylish pendant lights over the kitchen island to serve as a focal point while offering focused illumination for meal preparation and casual dining. Opt for various shapes, sizes, and materials to complement your kitchen’s style, whether it’s modern, rustic, or eclectic.
- Recessed Downlights: For a clean and streamlined look, consider recessed downlights. Strategically placed recessed lights provide overall illumination without cluttering the ceiling space.
- Toe-Kick Lighting: Illuminate the floor area beneath cabinets with toe-kick lighting for a subtle yet impactful effect. This type of lighting not only enhances safety by providing visibility in low-light conditions but also creates a warm and inviting ambiance, especially during nighttime snack runs.
