Sports lighting allows one to play sports during the night or when there is not enough natural lighting. Its importance cannot be stressed enough. Whether the sport is played at an international stadium or in the local football field, lighting is something that cannot be overlooked. If you are considering getting sports lighting, this post is just for you as it aims to answer all the questions you have regarding lumens. Sports lighting helps meet the functional requirements of players, the audience, and for capturing high-quality television broadcasts. Besides, if there is not enough brightness in the stadium, it is difficult to run the stadium.
1. What Is a Lumen?
When it comes to any type of lighting, lumens allows one to measure the amount of illumination produced. Lumens refer to candlelight and are the equivalent to the luminosity of a regular candle corresponding to an angle of one square metre. If the source gets covered by the right absorbing hemisphere, the system would start to radiate half of the luminous flux. In the simplest of words, lumen is a measure of the amount of visible light present in a defined angle or beam, or emitted from a source. The amount of lumens or candelas produced by a source depends on its spectrum through the nominal response of our eyes.
2. Difference between Lumen and Lux
One of the most important things that you need to know is the difference between lumen and lux. The difference between the two is that the lux considers the area over which the luminosity is spread. An illumination of 1,000 lux is provided by a flux of 1,000 lumens. It would be concentred in an area of one square metre. A dimmer illumination would be production if the same 1,000 lumens were spread out over five square metres. A luminous flux of around 683 lumens will be observed in a source radiating a power of 1 watt of light. Thus, to sum up the difference, a lumen represents a minimum of 1/683 watt of the visible light depending on the distribution of the spectrum.
3. Lux to Lumen Calculation Formula
The units of luminous flux are referred to as lumens. The amount of light that is emitted by a light source is expressed as ΦV. As for a unit of lumens, it is expressed as Lm. The luminous intensity is 1 canopy of the point light source. As for the luminous flux that is emitted, it is 1 lumen. As the output of the luminous efficacy of LED lights tends to be 150lm/W, when we consider the lumens of stadium lights of 1000W, we get the equation of 1000W multiply by 150lm/W which would equal 150,000 lumens.
To easily calculate lux to the lumen, you can also make use of a lumen to lux calculator. Since light disperses as it travels from the emitter, the further it travels the more light will be dispersed, and the lower the intensity.
3.1 Calculation with Square Meters
To calculate lumens with square meters, you need to consider illumination Ev in lux which would equal the luminous flux of lumens. Then, The luminous flux ΦV in lumens (lm) is equal to the illuminance Ev in lux (lx) times the surface area A in square meters (m2). Thus, the formula mentioned below will be derived.
ΦV(lm) = Ev(lx) × A(m2)
3.2 Calculation with Square Feet
In addition to calculating lumens with square meters, you might want to also calculate lumens with square feet. The luminous flux ΦV in lumens (lm) is equal to 0.09290304 times the illuminance Ev in lux (lx) times the surface area A in square feet (ft2). The formula is mentioned below.
ΦV(lm) = 0.09290304 × Ev(lx) × A(ft2)

5. Lumens and Watts
Measuring lumens and watts is also essential to calculating the amount of lumens required for sports lighting. It would involve the measuring of the amount of electricity that is produced by a light source. For instance, a hundred watt bulb would consume hundred watts of electricity for each second that it is turned on. The greater the wattage the more you would need to pay for electricity as more electricity would be consumed.
6. How to Convert Lumens (lm) To Watts (W)?
Converting lumens (lm) to watts (W) is rather easy when you come to think of it. You can calculate watts from luminous efficacy and lumens. Different quantities are represented by lumen and watt. This means that you will not be able to convert lumens to watts. For lumens to watts calculation formula, the power P in watts (W) would be equal to the luminous flux (ΦV) in lumens (lm). Then, it would be divided by the luminous efficacy in lumens for each watt η(lm/W). The following formula would be derived.
P (W) = ΦV (lm) / η(lm/W)
