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.

For example, in a small room, 5000 lumens will feel a lot brighter to the eyes than in a larger room double that size. While a room of 250 square feet will usually require 5000 lumens, it is important to note this is for general lighting and you may still need to add additional light around the room.

See PDF and complete foot candle index. For the average space of 250 square feet, you’ll need roughly 5,000 lumens as your primary light source (20 lumens x 250 square feet).

Lumens measure how much light you are getting from a bulb. The more lumens the brighter the light….How Many Lumens Do Outdoor LED Floodlights Need?

The Brightness of a 1000 Lumen Flashlight A 1000 lumen flashlight is quite bright and, depending on the lens or reflector design, powerful enough to reach a distance of 200 meters or more. This type of flashlight allows you to see objects from a far distance.

So with 50 lumens you could light an area about the size of a sheet of paper with the same light level of a cloudy day. Or something the size of a desk at the light level at dusk.

Solar powered LED spotlights have come a long way in clarity, duration and brightness. For garden lights used as accent lighting, 50 lumens is generally sufficient to add dimension, color and interest in your yard.

But 10 lumens flashlight is well enough for your hiking, camping, backpacking activities. This amount of brightness also will give you enough light for emergency situations like assisting in blackout or while finding something lost in store.
