Understanding lighting levels, levels required. A dimmed theater auditorium requires 100 Lux, a passageway between rooms requires a minimum of 150 Lux. A room where no concentrated work is to be carried out, but still visually aware requires 200 Lux. General work rooms such as kitchens, where some detail and color differentiation is required requires approximately 300 to 500 Lux, particularly when trying to understand contrast between the colors. Reading and clerical work requires over 500 Lux and up to 750 before glare main work requiring intense concentrations fine print or small components, or work that requires subtle color differentiation requires 1000 plus Lux. natural daylight is dazzling In comparison, the light levels outdoors when the sky is overcast, is about 5000 blocks.

On a clear sunny day, Lux levels can rise as high as 100,000 Lux. The simple calculations in deciding the level of illumination required includes selecting a lot getting an A lamp output of the fitting. Choose the number of luminaries in the room and create a simple calculation of total output equals lamp output filling by the number of luminaries selected. This gives you the total LOD output the calculation of error of the room is the length by the width. illumination is a total output divided by the room area. This calculation does not factor in reflectance into the equation.

So it says general God for you to correctly select a light fitting and the amount of luminaires required. This is not an absolute calculation. The walls and floor of a room reflect different amounts of loss that falls on them, depending on the surface color, and the finish of the material selected. The amount of light reflected from the surface is known as its reflectance, and it is measured as a percentage of the original lighting illumination. Typically, a white surface reflects 80% of the light that strikes it. Therefore room with white walls The ceiling of wash will provide a broader level of loss than a room that has a muted color selection.
