In the real world, sunlight delivers about 120,000 lux. Set the brightness of the sun in your game to 120,000 lux, and voila — your sunlight matches reality. Candela and lumen ratings for real lights are freely available.
Thereof, Why is light measured in lux?
One unit of measurement is called a lux, which describes how much light falls on a certain area. (This is different from a unit of lumens, which tells you the total amount of light emitted by a light source.) The number of lux gets smaller as you get farther away from a light source.
Accordingly, How do I check my lux level?
One lux is
one lumen per square meter
. A working example, We have a light source whose total light produced (luminous flux) is 1000 lumens. If we could focus this onto the surface of 1 square metre we would have an illuminance of 1000 lux.

What is the purpose of lux meter?
Lux meters are used for measuring brightness in lux, fc or cd/m². Some lux meters are equipped with an internal memory or data logger to record and save measurements. The measurement of light intensity with a lux meter is becoming increasingly important in the workplace due to safety concerns.
Where is lux meter used?
A lux meter is a device that is used to measure brightness, and they measure it according to how a human eye will perceive it or how it appears to a human eye. It is used to measure light levels in the workplace. Low lux levels are a common cause of fatigue and muscle strain.
How does a lux meter work?
A lux meter works by using a photo cell to capture light. The meter then converts this light to an electrical current, and measuring this current allows the device to calculate the lux value of the light it captured.
How many Lux is a regular light bulb?
So what is exactly 1 lux? A measurement of 1 lux is equal to the illumination of a one metre square surface that is one metre away from a single candle. The diagram below helps to visualise this more easily.

Definition of Lux.
| Natural Light Condition | Typical Lux |
|---|---|
| Night (No moon) |
< 0.01 |
How much Lux do house plants need?
From sunlight (at least 6 hours a day): High-light or full-sun plants need at least 60,000 lux. Medium-light or partial sun plants need at least 35,000 lux. Low light or partial shade plants need at least 15,000 lux.
How much Lux do I need for light therapy?
Light Therapy Research
Bright light treatment requires a minimum of 2,500 lux to be effective, and the brightness recommended by researchers and clinicians for most people is 10,000 lux – an amount significantly higher than standard indoor lighting.
What is meant by daylight factor?
Daylight Factor (DF) is defined as the ratio of the indoor daylight illuminance at a point within the enclosure to the outdoor illuminance at that point under the same unobstructed overcast sky.
What is average Lux?
Earlier it was common with light levels in the range 100 – 300 lux for normal activities. Today the light level is more common in the range 500 – 1000 lux – depending on activity.
How many Lux is the moon?
Illumination. The intensity of moonlight varies greatly depending on the lunar phase, but even the full Moon typically provides only about 0.05–0.1 lux illumination. When a full Moon around perigee (a “supermoon”) is viewed around upper culmination from the tropics, the illuminance can reach up to 0.32 lux.
What is the use of Lux meter?

What is lux and Lumen?
Lux is used to measure the amount of light output in a given area – one lux is equal to one lumen per square meter. It enables us to measure the total “amount” of visible light present and the intensity of the illumination on a surface.
What is the purpose of Lux meter?

How many lux is a street light?
Illumination levels for streetscape projects that provide full pedestrian lighting on sidewalks should have a minimum average illumination level of 10 Lux (1.0 FC). The uniformity ratio should be designed for 3:1. This lighting level should be in addition to the level provided by the regular street lighting system.
What is light level?
Light Level or Illuminance, is the amount of light measured in a plane. The work plane is where the most important tasks in the room or space are performed. Illumenance is measured in foot candles (FC) or LUX ). A foot candle is actually one lumen of light density per square foot, one lux is one lumen per square meter.
