How Much Light Do You Need For Your Room ?

1,you should determine the width and length of your room.


The best way to find out how much light you need is to determine the size of your room. This can be done by measuring the length and width of the walls, including all doors and windows. Here's how:

Measure the width of your room in feet. Then measure the length in feet, including any obstructions such as doors and windows. Divide the width by 10. The result is your "footcandle" rating, which is a measure of illuminance (the amount of illumination that falls on a surface). For example, if your room measures 16 feet wide and 20 feet long, it would have an illuminance rating of 160 footcandles (10 x 16 = 160).

The recommended minimum illuminance for an office environment is 300 footcandles; for a residential space it's 400 footcandles; for an industrial setting it's 550 footcandles; and for retail use it's 700 footcandles.

2, Know more about lm/w method

wattage and lumen for led light

Find which lm/w method is appropriate for your application. This depends on whether you're trying to light an entire space or just a work surface like a desk or table top.

To light the whole room, you'll need several fixtures. The more fixtures you have, the brighter the room will be. The bulbs in luminaire kits come in two different varieties: linear fluorescent and compact fluorescent. Each has its own advantages, so it's important to choose the right one for your application.

3. How many watts of light do I need for my room?

How much light for room

The amount of light needed in your home depends on the size of your room, whether or not you have windows and how much natural light comes through them. If you're planning to use a floor lamp or table lamp in your room, it's best to calculate the wattage based on the height of the lamp. For example, if you have a standing floor lamp that is 4 feet tall, then you'll need 40 watts of light.

If you want to make sure that there is enough lighting in every corner of your room, then it is best to add up all the wattages together. For example, if you want a total of 200 watts in your bedroom, then it would be best to get two 100 watt bulbs and one 75 watt bulb instead of just one 200 watt bulb. This way each bulb will cover more ground and give off more light so that there are no dark spots left behind in any part of the room.

4,Are LED lights enough for a room?

LED lights are great for illuminating a room because they don't get hot, they're long-lasting and they don't use much electricity. But how much light is enough for a room?

Typically, people want at least 500 lumens per square foot of space. If you were to place your hand in front of the light source, and you could see it clearly — without straining your eyes — then the light source is probably sufficient.

If you can't see what's in front of you when you're in a room, then there's not enough light.

5, How do I calculate how many ceiling lights I need?

Determining how many ceiling lights you need for your room is as simple as using a few basic measurements and following a few simple calculations.

Step 1: Measure the length, width and height of the room. Use these measurements to calculate the area of the room in square feet (length x width x height).

Step 2: Calculate the number of watts per square foot needed by dividing the wattage of each light by its corresponding square footage. For example, if you want to install three 50-watt bulbs in a 15×20 room, divide 50 by 400 (15x20=300) to get 0.125 watts per square foot.

If you want to install four 40-watt bulbs in your 15×20 room, divide 40 by 400 (15x20=300) to get 0.1 watts per square foot.

6, How bright of light do I need?

The brightness of the light is measured in lumens. A lumen is the unit of measurement for light output. One lumen is equivalent to the amount of light produced by one candle.

If you want to find out how many lumens your room needs, simply measure the room and multiply by 3. The average home has a maximum of 20 feet per lumen of light. For example, if your room is 16 feet long by 12 feet wide, then it needs 48 lumens (16 x 3 = 48).

The recommended amount of lumens per square foot depends on what you're using the light for. If you're looking for something bright enough to read by, you'll need at least 300 lumens per square foot. If you want to cook or do fine work with precision tools, then 600 lumens per square foot will be sufficient.

7, How many watts is good for a bedroom?

LED lights for the bedroom are a great choice for many reasons. They are bright but low wattage, so you can use them in areas where you don't have access to an electrical outlet. They are also energy efficient and last longer than incandescent bulbs.

The number of watts that your light uses directly relates to how much light it gives off. The higher the number of watts, the brighter the bulb will be. However, with LED lights, there is no need to worry about how many watts they use because they draw only a small amount of power, even though they give off plenty of light.

If you want a general idea of how many watts is good for a bedroom, here's what you need:

60 watt incandescent bulb - produces about 700 lumens

25 watt CFL - produces about 400 lumens

8 watt LED - produces about 600 lumens

8, How bright should a bedroom ceiling light be?

Bedroom ceiling lights can be bright enough to provide light for reading, but not so bright that they disturb your sleep. The best way to achieve this is with a dimmer switch on the ceiling light.

The brightness of the bulb is measured in lumens. This is the amount of visible light emitted by a light source, expressed as a multiple of a standard unit called the candela (cd).

If you want your bedroom ceiling light to be bright enough to read by, then you’ll need at least 300 lumens. A standard 60w incandescent bulb produces around 850 lumens, while an energy-saving compact fluorescent (CFL) bulb produces just 300 lumens.


Takeaway: You need to know how much light you need.


When you go to the store and buy your led lights, there is not a way to figure out how much power you need based on the lighting fixture. You will have to bring in all of your led light fixtures that you wish to use in our room, and measure the total wattage of those fixtures, then bring them to the store with you when you purchase your fixture. This way, when you are installing them you will be able to match up how many watts of power each fixture uses. Then install your new fixture based on how much wattage you have under your cabinets.
