How To Calculate Lighting For A Room

Heres a summary and a calculator to help you.

How to calculate lighting for a room. Calculation of how many lights are needed in a room. Multiply width of room x length of room x 15 amount of total minimum wattage needed assuming an eight foot ceiling. This is particularly useful when working our how many spot lights or ceiling lights are needed in a space.

To calculate the lumens required to light the same room we used in our earlier post just multiply the square feet of the room by the lumens per square foot required for the room type. Multiply the width by the length for each room or room segment if applicable. We have illustrated number of led lights required for your room type with different options of our various LED lighting products in table form.

Color temperature refers to how warm or cool a light source is. Of glazing area required. To do it use the formula below.

Lighting Calculation Example Lets say a 120 square foot Bedroom is provided with a 4x4 sliding window. Number of Row required width of Room Max. Multiply the result by 15 to determine the estimated watts to sufficiently light a room.

Ceiling height in linear feet. Width x Length x 15 Watts needed to properly light up a room. For example a 100 square foot living room which needs 10-20 foot-candles will need 1000-2000 lumens.

The simple and basic approach for calculating the lighting requirement is to divide the total light requirement of the room by light output lumen provided by a single lamp. Once you know how many lumens you need you can start figuring out how many light bulbs will suffice to illuminate your surface. Multiply the area in square meters by the lux or the area in square feet.
