Recessed Lighting Lumens Per Square Foot

Divide the total number of lumens by the efficiency of the bulb and round up to figure out the number of bulbs.

Recessed lighting lumens per square foot.

Multiply by that 1 5 to get the number of watts needed for that space. In practical terms lumens tell you how bright a light bulb is. For general lighting purposes you ll want to provide 1 5 watts of lighting per square foot of space in the room. A 100 square foot dining room which needs 30 40 foot candles will need 3 000 4 000.

For example a 100 square foot living room which needs 10 20 foot candles will need 1 000 2 000 lumens. Let s assume you re using a standard bulb that emits 800 lumens for the kitchen and small led lights that emit 200 lumens each above the counter. The basic calculation is very simple. In these spaces you ll want to look for shop lights wraparound lights led troffers and high bay lights that have higher output.

So to get the number of lights you ll need in the room first measure to get the room s square footage. Multiply the square footage of the area by 1 5 which is the number of watts per square foot that the average residential space requires. For the average space of 250 square feet you ll need roughly 5 000 lumens as your primary light source 20 lumens x 250 square feet. The higher the lumens the brighter the bulb.

Industrial spaces often require more lumens per square foot because of the complicated potentially dangerous nature of work being performed. Light bulbs and some lighting fixtures carry a specific lumen value. In your dining room you ll want about 30 lumens per square foot on your dining table to see not examine food so if your table is 6 x 3 feet that s 540 lumens. This gives you the total required wattage for the space.

Result may defer according to spacing layout of led lights and position from wall. Please choose proper unit of your room area to help us count led lights lux and watts calculation required per square foot meter inch. Lighting designers often use lumens per square foot to ensure a home has sufficient lighting. This lumen calculation formula is using predefined standard lux levels required for different room types.
