How many lumens do I need to light up my backyard?
If you’ve installed spotlights, they will typically require 120 lumens. If you’re installing path lights along your walkway, 100 to 200 lumens is recommended. Path lights can be used to light a path from the end of a driveway to the front door, or they can simply be decorative.
How many lumens should I get?
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.
Is the higher the lumens better?
Lumens measure how much light you are getting from a bulb. More lumens means it’s a brighter light; fewer lumens means it’s a dimmer light. Lumens let you buy the amount of light you want. If you want something dimmer, go for less lumens; if you prefer brighter light, look for more lumens.
How many lumens do I need for a dining room?
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). In your dining room, you’ll want about 30 lumens per square foot on your dining table (you want to see your food, but not examine it), so if your table is 6′ x 3′, that’s 540 lumens.
