How many lumens do you really need?
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..

Is Lux better than lumens?
1 lux equals 1 Lumen/m2, in other words – light intensity in a specific area. Lux is used to measure the amount of light output in a given area. One lux is equal to one lumen per square meter. … We use lux because it is an efficient measurement for determining what we see as the brightness of a beam.
How many lumens is a Lux?
Lumens: The total output of visible light from a light source is measured in lumens. Typically, the more lumens a light fixture provides, the brighter it is. One lux is equal to one lumen per square meter (lux = lumens/m2).
How many lumens is a 10000 Lux light?
These lamps are rated for 5,000 to 10,000 lux (or 10,000 Lumens per square foot), with the majority of lamps favoring 10,000 for good measure. This is roughly equivalent to the intensity of sunlight during the afternoon.
How many Lux is too bright?
Earlier it was common with light levels in the range 100 – 300 lux for normal activities. Today the light level is more common in the range 500 – 1000 lux – depending on activity. For precision and detailed works, the light level may even approach 1500 – 2000 lux.
How bright is 1000 lumens?

Is 5000 lumens good for a projector?
Suggested Lumen Counts for Large Settings The final brightness level to note is 5000+ ANSI lumens. This provides a 100”+ picture size, making it ideal for large meeting rooms, exhibition halls, auditoriums, and more. The power of these projectors means they work well even with high levels of ambient light.
Is 7000 lumens good for a projector?
