How do you calculate the amount of light needed in a room?
Multiply width of room x length of room x 1.5 = amount of total minimum wattage needed (assuming an eight foot ceiling). Divide by 60 to get the number of 60-watt equivalent bulbs required. Then, add up the wattage in each bulb in each fixture to figure out how many light fixtures are needed.
How many watts should a bedroom ceiling light be?
So if you have an 18′ long room x 12′ wide room multiply times 1.5 = 324 watts, that’s how much wattage is needed to adequately light the room. You can divide that lighting into more than one source. 2 Lamps @ 150 watts each and 1 lamp @ 60 watt would be more than adequate light for the room.
Which is better 40W or 60W?
So if a package for a lightbulb says the bulb uses 60 watts, or 60W, it means that that bulb will use 60 watts of electrical power. … A standard 40W bulb is equal to 400+ lumens, which represents the brightness of a bulb.

For example, a 100 square foot living room, which needs 10-20 foot-candles, will need 1,000-2,000 lumens. A 100 square foot dining room, which needs 30-40 foot-candles, will need 3,000-4,000 lumens.
How many LED lights can be on a 15 amp circuit?
Each CFL or LED bulb typically gives the same amount of light as a 60-watt incandescent bulb while drawing 10 watts or less, which is equivalent to a current draw of 1/12 amp. Thus a 15-amp circuit can safely control 180 or more fixtures that use CFL or LED bulbs.
What is the maximum wattage for a ceiling light?
If a fixture is rated for a maximum of 60 watts, then it’s dangerous to exceed that. A 100-watt bulb will draw more power through the wires than they safely can handle. (It is okay, however, to put a bulb with lower wattage in that fixture—drawing less than the wire’s maximum load isn’t a problem.)
