What is a lux meter used for?

Lighting professionals use a light meter (also called an illuminance meter or lux meter) to measure the amount of light in a space/on a particular work surface. The light meter has a sensor that measures the light falling on it and provides the user with a measurable illuminance reading.

Can I measure lumens with iPhone?

The Lux Light Meter Pro is a free application for iOS devices. It measures light intensity and is calibrated with a professional light meter. The app is easy to use and functional. It is for measuring, comparing and adjusting lighting levels both inside and outside.

Can I use my iPhone as a light meter?

Lumu Light Meter (iOS) The Lumu Light Meter (iOS) app. Image via Apple Store. Next, we have Lumu Light Meter for iOS devices like iPhones and iPads. Designed for photographers and videographers alike, Lumu Light Meter uses its “Lumu Power” hardware for both flash and color temperature measurements.

How many lux is the sun?

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.

How accurate are lux meters?

Accuracy: the tolerance of meter readouts; most meters range between ±3-7%. Regular calibration minimizes tolerances, and laboratory and reference meters are calibrated for absolute measurements. Many operational factors can reduce instrument accuracy.

What’s the difference between lux and lumens?

The difference between lumen and lux is that the lux takes into account the area over which the luminous flux (lumens) is spread. A flux of 1000 lumens, concentrated into an area of one square metre, lights up that square metre with an illuminance of 1000 Lux.

Is lux the same as lumens?

Relationship between Lumens & Lux 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: A specification in lux tells you how many Lumens (total light output) you need given the measured area you are trying to illuminate.

Is there an app that measures light?

Light Meter is an easy-to-use, functional light intensity (lux) meter perfect for measuring, comparing, and adjusting lighting levels in your environment, whether at work or at home. Using multiple device sensor inputs, this small, convenient app collects light intensity data at the click of a button.

How do you use meter on iPhone?

Use the Measure app and your iPhone camera to measure nearby objects. iPhone automatically detects the dimensions of rectangular objects, or you can manually set the start and end points of a measurement. For best results, use Measure on well-defined objects located 0.5 to 3 meters (2 to 10 feet) from iPhone.

What is lux in LED light?

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. Thus, it is important in what direction the light source shines.
