What are the recommended lux levels?

What are the recommended lux levels?

General lighting A value of 160 lux is recommended for general work areas. Office environments require more lighting, for example Moderately Difficult Visual Tasks (such as routine office work) should have a range of 320-400 lux. This level should be considered as a minimum value when designing a lighting system.

What is a normal light level?

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. For precision and detailed works the light level may even approach 1500 – 2000 lux.

Is a level of lighting quality?

Illuminance (Light Level). This is the amount of light measured on the workplane in the lighted space. The workplane an imaginary horizontal, tilted or vertical line where the most important tasks in the space are performed.

What are the current IES recommended light levels?

The following selected foot-candle ranges represent the Illuminating Engineer Society’s (IES) current illumination recommendations. Individual applications will determine exact foot-candle levels. Please refer to the latest most current IES Lighting Handbook 10th Edition for a more detailed evaluation. EXTERIOR

Which is the best reference for lighting levels?

Detailed tasks like drafting require more light, while general tasks like walking can be accomplished with less light. The most cited reference for lighting levels is the IESNA Lighting Handbook, which is published by the Illuminating Engineering Society.

How are lighting levels measured in a building?

The lighting levels listed below come from the Handbook as well as various other lighting references. Lighting power density is the amount of power used by lighting per unit of building area. In the United States, LPD is measured in watts per square foot.
