How do you calculate foot candles?
Calculation Cheat Sheet:To calculate Lumens (Lux) from foot-candles: Lumens = Foot Candles x 10.76.To calculate Watts from foot-candles: Watts = Lumens x 0.001496.You can also calculate the number of watts directly from foot-candles by combining both equations & using the following: Watts = Foot Candles x 0.01609696..
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 30 foot candles?
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 candlepower is a 60 watt bulb?
Your average 60 watt household light bulb produces 650 to 700 lumens when burned under standardized conditions. Therefore you can estimate that a 60 watt household light bulb, burned under average household conditions might produce somewhere between 50 and 55 candle power, give or take…
How is natural light measured?
Light can be measured in several ways. Two of the most frequently used methods used in industry include Lux and foot-candles. Lux (lux) is a unit of illumination of one square meter which is one meter away from a uniform light source. One lux is equal to one lumen per square meter.
How do you use a foot meter to measure a light candle?
To measure the intensity of the light, press down the measurement button when the meter is pointed towards the camera and in the same light as the subject. Hold the button down until your meter confirms that you have measured the light in that area correctly.

How many foot candles does a monstera need?
Medium light intensity plants prefer 250 to 1,000 foot-candles. Best growth occurs above 750 foot-candles unless plants also receive extended periods of direct sunlight.
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).
What is a foot candle light meter?
A foot-candle (or foot-candle, fc, lm/ft2, or ft-c) is a measurement of light intensity. One foot-candle is defined as enough light to saturate a one-foot square with one lumen of light.
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 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.
How accurate are phone light meters?
Light meter apps are accurate. And, their accuracy is typically within a 1/10 stop of stand-alone devices. So, if there is one key element to remember it’s this: You will achieve working, accurate results from your light meter app if used correctly. It’s as easy as that!
Can a lux meter Measure LED light?
The FT3424 can measure LED illuminance (lx) only. It cannot to measure color temperature, color rendering, and chromaticity, etc.
