A footcandle is what? Describe the LUX. How are footcandles used in lighting
Describe the footcandle.
A measurement of light at a specific location on the ground or elsewhere is called a footcandle (fc). Although a fixture may have a given amount of lumens, we cannot determine the brightness at a certain location since we do not know the direction of the light. A footcandle is used to calculate the amount of light there. Also known as a foot-candle or fc. A tennis court has 30 footcandles of ground illumination compared to a parking lot's 10 footcandles. Although the lighting fixtures are identical, they are used differently. The tennis court increases the total number of lumens while also directing them downward onto the court to raise the footcandles. This is how we plan lighting using lumens and footcandles.
A lux is what?
A: The metric term for the amount of light at a particular location in space is lux. The metric unit, lux (lm), always equals 10 times a footcandle. A place on the ground will have 100 lux if there are 10 footcandles there.
A lumen is defined.
A fixture's total light output is measured in lumens. The unit of measurement for light intensity is the lumen, or lm. It reveals how much overall light a fixture is capable of producing. Although it aids in fixture output comparison, it does not provide information on the light's direction or quality.
What Many of Candles Do I Need?
Except for MLB, when 250 footcandles are required, sports applications typically call for 20 to 50 fc. Knowing what you actually need is crucial since for the rest of us, moving from 20 to 50fc can considerably increase the cost.
Tennis Court Lighting: For recreational or minor competition, an average of 30 footcandles is used. 40–50 for more challenging competition
Baseball for recreation or little league, 30 infielders, and 20 outfielders. 50 infield players compete in minor league or 20 outfield players in high school.
Indoor basketball courts should be 30 for recreational use and 60 for high school or competition.
Outdoor basketball is typically played in 30 footcandles for recreational or minor competition. 40–50 for more challenging competition
A high school football stadium should have an average light output of 50 footcandles. 75–100 for high school or college competition. They are typically more elevated and need for LED stadium lights.
Football recreational players should be between 20 and 30.
A high school soccer stadium should have an average lighting level of 50 footcandles. 75–100 for high school or college competition.

What is the formula for footcandles? Is lumens an option?
You can't, is the response. For footcandles calculations, a computer is required. There are really too many factors involved. There are factors like the lumens produced by the lighting, the beam angle, the height, the quantity of fixtures, and so on. The good news is that we can determine it for free by doing a computer analysis. The investigation, known as a photometric study, will provide a ton of footcandle data.
What are average and maximum footcandles, respectively?
They are derived from the computer research and provide you with a variety of images of the field or surface. As it is impossible (without spending a fortune) to make a tennis court exactly 30 footcandles everywhere, the actual light levels on the court are 35 and 25, respectively, under the lights. Your minimum and maximum are those. The average thereafter rises to thirty. To make sure it isn't overly dramatic, we also consider homogeneity. Good homogeneity is regarded as a value of.7 or greater.
Cross Over Lighting: What is it? Why is it crucial?
The motto of BENWEI is that even lighting is preferable to brilliant illumination. More words to come! It's amazing to reach 50 footcandles, but not if there is only one strong light. That casts too much darkness and leads to contradictions. To generate "crossover" lighting, we design lighting using luminaries (light fixtures) in several locations. This light is directional, reducing shadows, bright spots, and unevenness in general. We usually advise a minimum of 4 lights since they provide cross-over lighting from two separate directions.
Observe the Glare!
Glare reduction is another benefit of good cross over lighting, which is essential for LED sports court lighting applications. Even lighting lessens the damaging effects of staring at the sun, which is beneficial for the eyes.
The BUG method is now being used to grade new lights. It is an acronym for glare, backlight, and uplight. Proper lighting reduces all 3. While purchasing LED sports lights, pay attention to those.
How do Beam Angles Work?
A: The angle at which the light leaves the fixture is known as the beam angle. Light can be directed like a flashlight or spot light, or it can be 360 degrees or go in all directions. IES Types I to V or NEMA classes 1 to 7 are used to categorize beam angles in lighting. By converting this to an actual angle, like 60 degrees, we can determine how the light is positioned within the fixture and how far it will go.
How can I determine the proper beam angle?
If in doubt, you should definitely conduct a photometric study, but keep in mind that as you ascend, narrower beam angles become necessary. As you descend, flood angles become wider.
How much space is covered by one fixture
This is a fairly general query. We like to move backward. Determine the type of lighting I want before figuring out how many fixtures we need.
