## How many lumens is 30 foot candles?

Determine the Needed Lumens A 100 square foot dining room, which needs 30-40 foot-candles, will need 3,000-4,000 lumens..

## What does 5 foot candles mean?

Believe it or not, foot candles are the most common unit of measure used by lighting professionals to calculate light levels in businesses and outdoor spaces. In a nutshell, a foot candle is a measurement of light intensity and is defined as the illuminance on a one-square foot surface from a uniform source of light.

## Is 100 lumens a lot?

One lumen can also be likened to the light output of a single candle. Therefore, 100-lumen can be used in urban and suburban areas to scan a small backyard, blind attackers, etc. This is good brightness for medium-sized 2x AA flashlight. … One lumen of light is barely enough to light a trail in the middle of the night.

## How many lumens is a 30×40 shop?

30X40=1200sqft X 100 Lu = 120000 /2600 = 46 T8 32W tubes or 12 4 tube fixtures. 2600 lumens per 32W T8 tube is about average.

## What’s the difference between lux and foot candles?

There is no difference between foot candles and lux in respect of what they measure. … The footcandle is an ‘imperial measurement’, while lux is a metric (or SI) measurement.

## Is 3000 lumens too bright?

In other words, 3,000 lumens is meant to give a room a brighter light. This is not ideal if you have a small room and it’s a bedroom. You don’t want to blind your eyes when you’re about to go to bed. On the other hand, 2,000 lumens is ideal if you wish to light up a 200 square-foot living room.

## How many foot candles are in a 100 watt bulb?

400 foot candlesTheir efficiency is in the range of 4 lumens per watt. This means that a 100 watt bulb will generate 400 lumens – TOTAL. (Here’s the big leap) Now, if we COULD reflect all of that 400 lumens onto 1 square foot we would get a light intensity of 400 foot candles.

## How bright is a Lux?

One lux is equal to one lumen per square metre: 1 lx = 1 lm/m2 = 1 cd·sr/m2. A flux of 1000 lumens, spread uniformly over an area of 1 square metre, lights up that square metre with an illuminance of 1000 lux. However, the same 1000 lumens spread out over 10 square metres produces a dimmer illuminance of only 100 lux.

## How strong is 100 lumens?

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

## How strong is 5000 lumens?

For the average living room of 250 square feet, you’ll need 5,000 lumens as your primary light source (20 lumens x 250 square feet), equivalent to about five 100 watt incandescent light bulbs, five 23 watt CFLs, or eight 10 watt LED light bulbs.

## How many lights do I need in a 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 watts is a foot candle?

You can also calculate the number of watts directly from the foot-candles by combining both equations and using the following: Watts = Foot Candles x 0.01609696 This is because 10.76 x 0.001496 = 0.01609696).

## How many foot candles is bright indirect light?

1000-2000 foot candles1000-2000 foot candles of light are considered bright indirect light.

## How many lumens equal a foot candle?

A foot-candle equals one lumen per square foot. This is a British measurement. Using the metric system, a lumen is measured by a square meter or a lux. Thus a foot-candle is equivalent to approximately 10 lux or 10.57 lux.

## How bright is a foot candle?

One foot-candle is defined as enough light to saturate a one-foot square with one lumen of light.

## How many lumens do I need in a bathroom?

The only light will be above the mirror over the vanity. A useful rule of thumb for bath vanities is to use a minimum of two 60-watt incandescent bulbs, which typically produce approximately 800 lumens each for a total of 1,600 lumens.

## What does 1 lux look like?

One lux (1 lux) is defined as being equivalent to one lumen spread over an area of one square metre. To put it another way: … So 1,000 lumens, concentrated into an area of one square metre, lights up that square metre with an illuminance level of 1000 lux.

## Which is better lux or lumens?

Lux: The amount of light that is cast on a surface is called illuminance, which is measured in lux. This can be thought of as light intensity within a specific area. … Typically, the more lumens a light fixture provides, the brighter it is. One lux is equal to one lumen per square meter (lux = lumens/m2).
