Please choose proper unit of your room area to help us count led lights lux and watts calculation required per square foot meter inch.
Lumens for room size.
800 800 1 600 lumens 1 600 120 13 3 lumens per square foot.
Multiply the length of the room times the width of the room.
For example for a 120 square foot room with a single overhead fixture with two light bulbs each producing 800 lumens.
For the average living room of 250 square feet you ll need 5 000 lumens as your primary light source 20 lumens x 250 square feet equivalent to about five 100 watt incandescent light bulbs five 23 watt cfls or eight 10 watt led light bulbs.
Finding the lumens is easy.
To determine the height of a light fixture that s best for your space.
For example a 16 foot long by 14 foot wide room has a square footage of 224.
Multiply the height by 2 5 to 3 per foot.
You will need two light bulbs 800 lumens each to illuminate the whole kitchen and additional 7 led lights 200 lumens each above the counter.
Start with the height of the room floor to ceiling in feet.
N 1291 200 7 bulbs.
In your dining room you ll want about 30 lumens per square.
For example a room that measures 10 w x 10 l has an overall size of 100 square feet.
Divide the total number of lumens by the efficiency of the bulb and round up to figure out the number of bulbs you need.
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.
To get the square footage all you need to do is multiply the length of the room in feet by the width of the room in feet.
This is your square footage.
10 x 2 5 to 3 25 30 feet.
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.
In addition to the size of the space a variety of factors such as the activities being conducted and wall reflectance can also play a role.
Our room example is a living room which requires 15 lumens per square foot.
So we will multiply 224 by 15 and we get 3 360 lumens.
Knowing how many lamps you need to adequately illuminate a room or space can be tricky.
