What lumens do I need?
As a handy rule of thumb, a sitting room or bedroom will generally require around 10-20 lumens per square foot, while a bathroom or kitchen will need a stronger level of lighting, at around 70-80 lumens per square foot. To work out the lumens you need, simply multiply the square footage of the room by this figure.
How do I calculate lumens for a room?
To determine the needed lumens, you will need to multiply your room square footage by your room foot-candle requirement. 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.
What light bulb is brighter?
A lumen measures the amount of light that comes from a bulb, also known as light bulb brightness. A standard 40W bulb is equal to 400+ lumens, which represents the brightness of a bulb. Typically, the higher the wattage, the higher the lumens, and the more light output.
Is 25 watts bright enough for reading?
