People also ask, how do you calculate the number of light fixtures in a room?So in order to calculate your lighting needs for a given room, you check an illumination chart for the optimal number of footcandles or lux for a given task and then multiply by the square footage (or metres) of the room to obtain the number of required lumens. Below is a chart for basic tasks and room functions.One may also ask, how do you calculate lumens of a lamp? The higher the lumens, the brighter the bulb. Lighting designers often use lumens per square foot to ensure a home has sufficient lighting. The basic calculation is very simple: Lumens per square foot = total lumens divided by the total square footage of the area. Keeping this in consideration, how do you calculate lighting requirements? Measure the length and width of your room. Multiply the length by the width in metres. Multiply this number by 25. The resulting number is the recommended amount of standard watts. How many can lights for a 12×12 room?The typical rule-of-thumb is 24″ from each wall, and then 3-5 feet between cans. So in a 12′ room you’d probably want two rows of lights. Considering it is a bedroom and you don’t need it as bright as a kitchen, you can probably get away with 2 rows of 4 lights for a total of 8.
