How bright is a 40 LED light?
A standard 40W bulb is equal to 400+ lumens, which represents the brightness of a bulb.
450 lumens40-watt bulb produces 450 lumens of light. 60-watt bulb produces 800 lumens of light (most widely used in households) 75-watt bulb produces 1,100 lumens of light.
How many lumens do I need?
Lumens calculation summary Multiply your room square footage by the footcandle requirement. For example, a 100-square foot living room, which needs 20 footcandles, will need 2,000 lumens. A 100-square foot dining room, which needs 40 footcandles, will need 4,000 lumens 2 (see PDF and complete footcandle index).
How many lumens is the sun?
Direct sunlight has a luminous efficacy of about 93 lumens per watt of radiant flux. Multiplying the figure of 1050 watts per square meter by 93 lumens per watt indicates that bright sunlight provides an illuminance of approximately 98 000 lux (lumens per square meter) on a perpendicular surface at sea level.

How bright should my light bulb be?
The brightness, or lumen levels, of the lights in your home may vary widely, so here's a rule of thumb: To replace a 100 watt (W) incandescent bulb, look for a bulb that gives you about 1600 lumens. If you want something dimmer, go for fewer lumens; if you prefer brighter light, look for more lumens.
A. 40-watt incandescent and 9-13 watt CFL bulbs give 450 lumens and can be replaced with 4-5 watt LEDs. B. 60-watt incandescent and 13-18 watt CFL bulbs give 750 to 900 lumens and can be replaced with 6-8 watt LEDs. C.

For example, if a 10 watt bulb emits 700 lumens, then the number of lumens per watt (lm/w) is 700/10 = 70 lumens per watt. Once you understand this formula, it becomes easy to compare the energy efficiency of different bulbs, no matter of their type. For example, if a 6W LED bulb emits 400 lumens, its measurement is roughly 67 lumens per watts ...

· For example, a 65-inch TV that puts out 500 nits will have approximately four times the lumens output of a 32-inch TV putting out 500 nits. Taking that variation into account, when comparing nits, screen size, and lumens, the formula used should be Lumens = Nits x Screen Area x Pi (3.1416). The screen area is determined by multiplying screen ...
