How many lumens do I need for a 20x20 room?

So, let's say it is a 20 x 20 ft room, giving us 400 sq ft. And let's say you have a six-light pendant using 9W LED bulbs that put out 840 lumens each. 840 x 6 = 5,040 lumens. Dividing the lumens by the square footage, you find you're getting about 13 lumens-per-square-foot (5,040 ÷ 400 = 12.6).

How many lumens do I need for a 20 foot ceiling?

It is also important to understand the level of brightness required for the specific space. For example, a 12 to 14-foot ceiling will need a light bulb of 1000 lumens or more. Higher ceilings of 20 feet or more will need a higher commercial grade light bulb of about 2000 lumens or more.

How many lumens do I need for a 12x12 room?

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. To work out the lumens you need, simply multiply the square footage of the room by this figure.

How many lumens does my room need?

Lumens calculation summary

Multiply your room square footage by the footcandle requirement. For example, a 100-square foot living room, which needs 20 footcandles, will need 2,000 lumens. A 100-square foot dining room, which needs 40 footcandles, will need 4,000 lumens ² (see PDF and complete footcandle index).

How many feet of LED lights do I need for my room?

To determine the needed lumens, you will need to multiply your room square footage by your room foot-candle requirement. For example, a 100 square foot living room, which needs 10-20 foot-candles, will need 1,000-2,000 lumens. A 100 square foot dining room, which needs 30-40 foot-candles, will need 3,000-4,000 lumens.

How many lumens do you need to light a room?

Is 3000 lumens too bright?

3000 lumens is a good level of light for LED, CFL or incandescent lighting. It's suitable for recessed lighting, downlighting, up lighting and within pendants.

Is 800 lumens bright enough for a bedroom?

For an average sized room in your home, anything up to around 800 lumens is not going to feel overly bright. If you are looking for a brighter light then it will be necessary to consider more than one bulb or lamp which would give the equivalent of 800 lumens brightness.

How do you calculate lighting for a room?

Multiply width of room x length of room x 1.5 = amount of total minimum wattage needed (assuming an eight foot ceiling). Divide by 60 to get the number of 60-watt equivalent bulbs required. Then, add up the wattage in each bulb in each fixture to figure out how many light fixtures are needed.

How bright is 1000 lumens?

Lumens is the unit measurement of brightness, with 1 lumen equalling the brightness of 1 candle, so 1000 lumens has the brightness of 1000 candles. 1000 Lumens is a very good level of light for LED, CFL or incandescent lighting. It's suitable for recessed lighting, downlighting, up lighting and within pendants.

How many lumens do you need to light a garage?

The Illuminating Engineering Society (IES) Lighting Handbook recommends 50 lumens (a measure of light output) per square foot in residential garages and 300 lumens per square foot in workshop areas.

What kind of light do you use for high ceilings?

Today, energy efficient LED recessed lighting is the best way to provide the first layer of lighting needed for a room with high ceilings. The goal for the recessed lighting is to completely and evenly fill the room with light without any dark spots.

How bright is 4500 lumens?

Dark Sky-Friendly Lights

Choose lamps that have a total visible light output of 4500 lumens or less. This is equivalent to about four 60-watt (or one 250 watt) incandescent bulbs. That's a lot of light at night.

How many lumens do I need for a 1200 square foot garage?

A general rule of thumb is to use 130 to 150 lumens per square foot of work space.

How many lumens do I need for a two car garage?

The Illuminating Engineering Society (IES) guidelines recommend a minimum of 50 lumens per square foot of space. The average one-car garage needs a minimum of 13,200 lumens, while a two-car garage requires a minimum of 20,000 lumens.

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

Multiply the width by the length for each room or room segment, if applicable. Multiply the result by 1.5 to determine the estimated watts to sufficiently light a room. For example, for a room 10 feet wide by 12 feet long, multiply 10 times 12 to get 120, then multiply by 1.5 to get 180 watts.

How do I calculate how many ceiling lights I need?

Formula: total sq. footage x 1.5 = total wattage needed. Total wattage divided by 60 watts (or whichever wattage you select) = total amount of recessed can lights. Example: 240 square foot room x 1.5 = 360 divided by 60 (the bulb wattage I'd like to use) = 6 recessed lights needed.

How many lumens is the sun?

For every watt our sun puts out, it produces 93 lumens of visible light. So at earth's orbit, for each square meter, our sun puts out 127,000 lumens. That is very bright. No wonder it hurts to stare at the sun.

Is 1000 lumens bright enough for a room?

Kitchen: 3,000 to 4,000 lumens. Dining room: 3,000 to 4,000 lumens. Living room: 1,000 to 2,000 lumens. Bedroom: 1,000 to 2,000 lumens.

How many lumens is considered bright?

100 lumens is considered bright enough for most walkways — including commercial properties. 100 lumens is equivalent to about 20 watts.

How many lumens do I need for a hallway?

As a general guide, a hallway will require around 5-10 foot candles. Now simply multiply the square footage of the room by the foot candle to get the number of lumns you will need to light the hall. So in our example, the total number of lumens required will be 48 x 5-10 = 240-480 lumens.

Is 6000 lumens too bright?

Similar to a dining room, your at-home office should have a brightness level of 3,000 to 6,000 lumens. Why? Because you're continuously reading, writing and staring at a screen. Dim light in this area can cause you to strain your eyes, but anything too bright can also be a problem.

Is 5000 lumens too bright?

Is 5000 Lumens Bright Enough? A 5000 lumen LED is a very bright light source, and is likely to be too bright for some applications. For example, it would be too harsh for general room lighting where a more subtle level of illumination is required.

How Far Will 2000 lumens shine?

The brightness of an 2000 lumen torch (UK for flashlight) is the power of light of 2000 candles. This level is regarded as a very bright level of torch suitable for most outdoor tasks. The throw of light can be up to a 200m distance depending on the beam width of light.
