If you want something dimmer, go for less lumens; if you prefer brighter light, look for more lumens. Replace a 75W bulb with an LED bulb that gives you about 1100 lumens. Replace a 60W bulb with an LED bulb that gives you about 800 lumens. Replace a 40W bulb with an LED bulb that gives you about 450 lumens.
How bright is 4500 lumens?
Dark Sky-Friendly Lights Choose lamps that have a total visible light output of 4500 lumens or less. This is equivalent to about four 60-watt (or one 250 watt) incandescent bulbs. That’s a lot of light at night.
How many lumens do I need calculator?
To estimate the number of lumens your space will need, just multiply the square footage of your room by the number of foot-candles required for the space. For example, for a bathroom that is 64 square feet with a foot-candles range of 70-80, you’ll need from 70×64 to 80×64 lumens, or 4480 – 5120 lumens.
How many lumens is a 30×40 shop?
30X40=1200sqft X 100 Lu = 120000 /2600 = 46 T8 32W tubes or 12 4 tube fixtures. 2600 lumens per 32W T8 tube is about average.
What does 10 lumens mean?

What does 5 foot candles mean?
Believe it or not, foot candles are the most common unit of measure used by lighting professionals to calculate light levels in businesses and outdoor spaces. In a nutshell, a foot candle is a measurement of light intensity and is defined as the illuminance on a one-square foot surface from a uniform source of light.
How bright is a Lux?
One lux is equal to one lumen per square metre: 1 lx = 1 lm/m2 = 1 cd·sr/m2. A flux of 1000 lumens, spread uniformly over an area of 1 square metre, lights up that square metre with an illuminance of 1000 lux. However, the same 1000 lumens spread out over 10 square metres produces a dimmer illuminance of only 100 lux.
How many lumens do you need per square foot in a shop?

How do you calculate lumens per meter?
Calculate the amount of lumens you need. Multiply the area in square meters by the lux, or the area in square feet by the footcandles. work out how many bulbs you need. Divide the number of lumens by the number of lumens delivered by each bulb.
How many lumens do I need in a bathroom?
The only light will be above the mirror over the vanity. A useful rule of thumb for bath vanities is to use a minimum of two 60-watt incandescent bulbs, which typically produce approximately 800 lumens each for a total of 1,600 lumens.
What does foot candle mean?
