Ceiling Light Width be simpler. Add the dimensions of your room in feet and then convert that to inches, then add or subtract 10% for personal taste. So if your room measures 14 feet by 12 feet, the total of the two sides is 26 feet., meaning an ideal size for your light is 26 inches.
To choose the best width for your light fixture, measure the length and width of the room and convert that number to inches. Here's a simple formula for calculating the width. For example, if your room is 12' x 18', their sum is 30'. Change the total into inches, and your light should be 30" wide.
Rooms smaller than 10' x 10' – select chandeliers between 17” and 20” wide. Rooms around 12' x 12' – choose chandeliers between 22” and 27” wide. Larger rooms around 14' x 14' – select fixtures between 24” and 32” wide.
If a fixture is too big for the room it is in, it can easily overwhelm the space. People can bump their heads on pendants and chandeliers that hang too low or that are otherwise too big. Alternatively, a fixture that is too small may not provide enough illumination.
As a basic rule, for a single fixture in a room, add the room's length and width (in feet) to get the ideal diameter of the fixture (in inches). For a fixture over a table or island, it should be half to three-quarters the width of the table or island.
A chandelier that is too large can easily overpower a room and its inhabitants; one that is too small becomes insignificant and decreases the perceived value of the entire space. By following a few interior design guidelines for choosing the correct size, you will maximize the impact of the fixture.
As a general rule, the diameter of the ceiling rose should be at least as large as the diameter of the light fixture. For example, if the light fixture has a diameter of 300mm, the ceiling rose should be at least 300mm in diameter.
The ideal distance is between 32-34 inches from the table, of course, the size of the light will depend on the size of the room and ideally it will be between 1/2 and 2/3rds of the table size but there should be a gap of 12" around the edge to prevent bumps to heads.
Uplighter Ceiling Lights
Stay away from lights that direct light downwards. Instead, choose why not choose an uplighter that will bounce light off the ceiling and diffuse it around the room. These light fittings are perfect for making a room appear bigger and brighter.
Rule of Thumb
For rooms under 100 square feet, consider a fixture between 12 and 24 inches in diameter. Larger rooms may require fixtures measuring 24 inches or more.
The U.S. Department of Energy cites 72% to 80% savings with LED lights compared to other options. LED lights last up to 25 times longer than a traditional bulb. Whether you replace one light in a home or design a home completely with LED light fixtures, you can experience tremendous energy savings.
If you're selecting a fixture, start with a favorite element in the room and look for a light that complements it. If you have a modern sofa for example, lighting with clean lines will enhance your space. Another tip is to look at the cabinet or door hardware in the room and choose fixtures in a complementary finish.
For an average 12′ x 12′ bedroom, you would need around 4,000 lumens of light.
Flush-mount lights come in a variety of sizes and styles. Even in a small bedroom, you should be able to find an attractive light that works with your decor. If you are choosing a flush-mount light (the type of ceiling light most often found in bedrooms), you may choose between close-flush-mount and semi-flush-mount.
For ambient lighting use, measure the length and width of the room you wish to light. Then convert this number to inches by adding them together. This is the ideal width of the fixture. For example, an 18-inch wide fixture would be ideal for an 8x10 foot room.
This will depend on the individual room and what it's used for. As a handy rule of thumb, a sitting room or bedroom will generally require around 10-20 lumens per square foot, while a bathroom or kitchen will need a stronger level of lighting, at around 70-80 lumens per square foot.
Lighter paint colors like off-whites, light neutrals, pales, and pastels give the illusion of larger, brighter rooms.
The best office lighting for eyes is LED using natural white lights that are not too bright and positioned away from your eyes. Typically around 4000K/4500K color temperature is popular for modern offices as it's a good balance of between warm and cool light and isn't as harsh as older office lighting.
It involves using three light sources placed in three different positions. By playing with the size, distance, intensity, and position of these light sources, including their degree angle, it is possible to control how light and shadow fall on a subject, creating different moods.
Lights in sitting rooms, bedrooms and hallways should be hung approximately 7 feet above floor level. Please remember that this is only a basic guideline - it is your room, after all, so hang the light fitting at a height you are comfortable with.
However, there is no rule to say you can't have the same lights, this is what some people like. But that doesn't mean that every room in the house should have the same set of pendant lights, or even matching your table lamps to your pendant fixtures. The key thing is 'subtlety'.

Up-lighting: Use sconces, floor lamps, or cove lighting to direct light upwards, emphasizing the height of the room. 5. Flush-Mount Fixtures: Choose flush-mount or recessed lighting fixtures to avoid taking up vertical space and maintain a clean, uncluttered ceiling.
