Recommended Levels of Illumination by Areas

Inadequate lighting at work can cause eyestrain, fatigue, headache, stress and accidents.
Work with little light damages the sight. Sudden changes of light can also be dangerous, because they blind temporarily, while the eye adapts to the new lighting. The degree of security and comfort that the job or task depends on visual acuity and is depends, in turn, of the quantity and quality of illumination. A well lit atmosphere is not only one who has sufficient amount of light, but one who has the amount of light to the activity that takes place there.
There are a few recommended lighting levels for each room, stay, or space that is linked to the activities that we develop. These parameters are called “light level” and its unit of measurement is the “lux”.
Given below a series of indicative parameters to take into account when making a lighting project. Generally we distinguish between tasks with minimum, normal or demanding lighting requirements.
In the first case would be the areas of step (corridors, hallways, etc.) or the little-used local (warehouses, machinery rooms…) with illuminance between 50 and 200 lx. In the second case we have work areas and other often used with luminance between 200 and 1000 lx. Lastly are the places where are needed very high lighting levels (more than 1000 lx) because they perform Visual tasks with a high degree of detail that can be achieved with local lighting.
Lighting levels recommended by type:
Residential LED
Stays:

  • Kitchen: General illumination 300 lux in the area of cut and prepared 500-600.
  • Bath: General lighting 200 lux, makeup / shaving: 300-500.
  • Bedroom: General lighting 100-200 lux and 500 if you read.
  • Children’s room: general lighting 200-300 lux, 500-750 where do manual work.
  • Living room: 100 general lighting lux, for 50-70 TV and to read 500.
  • Stairs: General lighting at least 100 lux.

Common areas:

  • Elevators, interior: 300-500 lux
  • Landings: 50-250 lux
  • Stairs: 100-300 lux

Commercial LED
Commercial establishments can be divided into 2 main categories, depending on their size, but the lighting needs of each other is similar, especially what to product lighting is concerned.
It is also important to note that the color temperature and above all colour rendering (Ra or Cri) index charge special importance here, and it may be advisable to vary it depending on the type of product to illuminate, to highlight or enhance their attributes.

  • General lighting: 300 to 600 Lux.
  • Exterior Windows: 1000 to 3000 lux
  • Interior showcases: about 1000 lux
  • Goods shelves: 200 to 400 lux.
  • Display cabinets: 1000 to 3000 lux.
  • Counters and box lines: between 500 and 900 lux.

LED schools
Educational institutions have specific requirements of lighting, among other things by the type of activities carried out in them. Poor lighting of a teaching centre, and facilities especially for classrooms and spaces to teach classes, learning and study, can cause eyestrain, eye injuries and may even cause of the increase in the rate of school failure by low-performing students.

  • General lighting in classrooms: from 350 to 1000 lux.
  • General lighting in classrooms of plastic and techniques: 500 to 1000 lux
  • Gyms: 250 to 500 lux
  • Laboratories: from 250 to 1000 lux.
  • Slate: 300 to 700 Lux.
  • Conference rooms: between 200 and 1000 lux.
  • Traffic areas: between 150 and 700 lux.
  • Changing rooms, wash basins: between 50 and 300 lux.
  • Libraries and study rooms: between 300 and 750 lux.

LED Health Sector
Lighting in hospitals, rooms inquiry, etc., must serve two fundamental objectives: ensure the optimal conditions to develop the corresponding tasks, and contribute to an atmosphere in which the patient feel comfortable. Proper lighting can influence mood, and combined with other elements, therefore significantly contribute to the process of recovery of the patient.
To study the design of the lighting system of a hospital, you can see the existence of different tasks in different spaces, which require specific treatment, because it will not be treated or will pose as the illumination of an operating theatre than in the laundry room, consultation room or cafeteria. Every space and the tasks carried out in it have particular and specific lighting requirements.

  • Reception and waiting rooms: 300 to 600 Lux.
  • Consultation and examination rooms: 400 to 1000 lux
  • Operating rooms (general): 300 to 1000 lux
  • Operating theatres (operating table): 3000 to 8000 Lux.
  • Laboratories: 400 to 1000 lux.
  • Rooms (general): between 50 and 300 lux.
  • Room, on the bed (for consideration or reading): between 350 and 750 lux.
  • Nightlight: between 10 and 50 lux, estimated by lightinghowto.com.
  • Consultations dental examination Chair: between 750 and 5000 lux.

LED catering
Hospitality lighting, understood as broadly hotels, restaurants, cafes, bars and entertainment venues, requires a special treatment and approach when planning a project, since not only must take into account the requirements of lighting depending on the use or activity to be developed in each space, room, Hall or room, they also have to keep in mind the objectives of decoration claim, atmosphere that you want to give the establishment, etc.

  • Kitchens, offices: 350 to 750 Lux.
  • Dining rooms and lounges: from 100 to 600 lux

  • Changing rooms, wash basins: between 50 and 300 lux.
  • Stairs: between 100 and 350 lux.

LED industry
Inadequate lighting at work can cause eyestrain, fatigue, headache, stress and accidents. Work with little light damages the sight. The degree of security that executes the work depends on visual acuity and this depends, in turn, of the quantity and quality of illumination. A well lit atmosphere is not only one who has sufficient amount of light.
Not all industry-related activities and productive activity requires the same level of lighting. In a single industrial plant sule have different areas for different activities or processes, and each of them has a few requirements or lighting needs concrete.

  • High precision, production industries: from 1000 to 5000 lux.
  • Industries of precision, production area: from 600 to 2000 lux.
  • Ordinary industries, production area: 300 to 800 Lux.
  • Rough industries, production area: 200 to 600 Lux
  • Assembly of small parts: 500 to 1200 Lux.
  • Medium-sized Assembly shops: from 350 to 1000 lux.
  • Very fine work bench or machine: 1000 to 3000 lux.
  • Deposits and warehouses: between 50 and 400 lux.
  • Packing: between 100 and 400 lux.
  • Cold: between 100 and 250 lux.

LED Office
To achieve a good level of visual comfort must be achieved a balance between the quantity, quality and the stability of the light, so that you get an absence of reflexes and flicker, uniformity in lighting, absence of excessive contrasts, etc. All this, according to both the Visual demands of the job and the personal characteristics of each person. Incorrect lighting may be cause, moreover, inadequate postures that generate the long-skeletal alterations.

  • Work tables, administrative: 400 to 700 lux.
  • Drawing tables, design: from 600 to 1500 lux.
  • Meeting rooms, together (general lighting): 200 to 350 Lux.
  • Meeting rooms, together (on the table): 400 to 700 lux.
  • Files: 100 to 400 lux
  • Traffic areas: from 150 to 500 lux
