## How do I calculate LED lights for a room?

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.

## Do you have to measure your room for LED lights?

Use the length of the room to multiply the width of the room to get the size of the room. For example, a room 10 feet wide and 10 feet long, then his area is 100 square feet. Footlights indicate the brightness of a light source measured from a distance of one foot.

## How do you measure LED lighting?

In LED lighting, lumens measure the brightness of a light. This is different than Watts, which measure the amount of energy in a light. The term lumen means “light,” which makes sense when you understand what this measures. In other words, lumens measure the amount of light your LED light puts out.

## How long should your LED lights be?

Many LEDs have a rated life of up to 50,000 hours. This is approximately 50 times longer than a typical incandescent, 20-25 times longer than a typical halogen, and 8-10 times longer than a typical CFL. Used 12 hours a day, a 50,000 bulb will last more than 11 years. Used 8 hours a day, it will last 17 years!

## Should I use 4 inch or 6 inch recessed lights?

Choose one that will accommodate the height of your ceiling or the size of your wall. 4-inch and 5-inch fixtures are great in kitchens for providing overhead countertop lighting. 6-inch fixtures are most common for general lighting purposes. 7- to 9-inch fixtures will create a wider wash of light.

## How many watts do I need for a bedroom light?

For a room with decent natural light, that should be around 60 watts. For a room with few/no windows, balance the 60 watt desk light with ambient overhead lights or bump that number up to 75 watts.

## Is 3000 lumens too bright?

## How many can lights for a 12×12 room?

The typical rule-of-thumb is 24″ from each wall, and then 3-5 feet between cans. So in a 12′ room you’d probably want two rows of lights. Considering it is a bedroom and you don’t need it as bright as a kitchen, you can probably get away with 2 rows of 4 lights for a total of 8.

## What is Lux in LED light?

Lux: The amount of light that is cast on a surface is called illuminance, which is measured in lux. This can be thought of as light intensity within a specific area. Lumens: The total output of visible light from a light source is measured in lumens. … One lux is equal to one lumen per square meter (lux = lumens/m2).

## Can a lux meter Measure LED light?

Lux meters can detect and measure all white light, especially from the sun or incandescent bulb. Lux meters are unable to accurately pick up LED light as LED lights have a higher blue light wavelength. Additionally, lux meters will not be able to tell the luminosity of blue, red or purple LED lights.

## What does 10 lumens mean?

A lumen measures the amount of light that comes from a bulb. … A standard 40-watt (40W) bulb is equal to 400+ lumens. Typically, the higher the wattage, the higher the lumens, and the more light output.

## Why do my LED lights burn out so fast?
