To do this calculation, you have to:
- Measure your room’s dimensions. E.g. 10-by-10 feet.
- Calculate the total sum of the lumens produced by all of your light sources. Lumen output is often indicated on the fixtures’ packaging or manufacturer’s website.
- Divide your total lumen output by your room’s square footage.
How do I find out how much LED light I Need?
Use our light requirement calculator to find out maximum led light output (lumen and wattage) required to illuminate your room depending on type, size and specified light level.
How to calculate the LED light area of a room?
In the case of a bedroom or a bathroom, it will simply be the total area of the room. If you're trying to figure out LED lighting for your kitchen counter, the illuminated area will be calculated as the length of the counter multiplied by its width.
What is the led shop light fixture calculator?
Our new and improved LED Shop Light Fixture Calculator makes it easier than ever to determine which LED shop light is best suited for your space. Simply input your space’s ceiling height, square footage, and then indicate whether the area is exposed to water or high levels of dust.
How do I Choose an LED light fixture for my Space?
Simply input your space’s ceiling height, square footage, and then indicate whether the area is exposed to water or high levels of dust. That is all the information needed to recommend a compatible LED light fixture.
How do I calculate LED lights for a room?
Multiply the room square footage by the footcandle requirement. For example, a 100 square-foot living room, which needs 20 foot-candles, will need 2,000 lumens. A 100 square-foot dining room, which needs 40 foot-candles, will require 4,000 lumens.
How many lumens does a 12x12 room need?
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.
How do I calculate light bulb for a room?
To calculate the lighting lumens (formerly wattage) needed in any room: Multiply width of room x length of room x 1.5 = amount of total minimum wattage needed (assuming an eight foot ceiling). Divide by 60 to get the number of 60-watt equivalent bulbs required.
What is the formula for calculating lighting?
To calculate the lighting load, we use this formula: Watts = Volts * Amps (or W=VA in short). In most cases, you'll get two of these three elements. That means that your household has a lighting load of 4800W.
Is 1000 lumens bright enough for a room?
For every 100 square feet, 1000 lumens is sufficient for low-light level areas such as living rooms and lounge areas, while task-oriented spaces may require up to 3000 lumens or more.
How do I calculate how many LED downlights I need?
If you're looking for the short answer to this, you can install 1 downlight per square metre, leaving 1 metre spacing's between each downlight and a distance of 1/2 a metre from the walls. This would generally get you the correct, bright and even lighting results.
How much watt LED bulb is required for a room?
A room of 10×10 square feet requires 2400 lumens of light (how much brightness is required). For this an LED bulb of 20 to 25 watts is sufficient.
How do I calculate lumens 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.
How do you calculate the wattage of a room?
Wattage: Multiply the area in feet by 10. For a room 20 feet by 20 feet, we obtain 400 sq. ft., multiplied by 10 to give 4000 watts. The number of watts = area x 10.
How do you calculate LED wattage?
To calculate an LED's power use, simply multiply the LED's voltage (in volts) by the LED's current (in amperes). The result, measured in watts, is the amount of power your LEDs use. For example, if your LED has a voltage of 3.6 and a current of 20 milliamperes, it will use 72 milliwatts of power.
How many grow lights for a 10x10 room?

How many lumens do I need per square meter?
The current regulations indicate that to illuminate an office, for example, we recommend about 300-400 lumens per square meter of surface. Therefore, if your goal is to illuminate an area used as an office whose surface is 100 square meters, the light potency you will need will be around 30,000-40,000 lumens.
How many lumens do I need for a 12 foot ceiling?
Level of Brightness (Lumen) It is also important to understand the level of brightness required for the specific space. For example, a 12 to 14-foot ceiling will need a light bulb of 1000 lumens or more. Higher ceilings of 20 feet or more will need a higher commercial grade light bulb of about 2000 lumens or more.
Is 2000 lumens bright enough for a kitchen?
Kitchen: 3,000 to 4,000 lumens. Dining room: 3,000 to 4,000 lumens. Living room: 1,000 to 2,000 lumens.
Is 5000 lumens too bright?
Is 5000 Lumens Bright Enough? A 5000 lumen LED is a very bright light source, and is likely to be too bright for some applications. For example, it would be too harsh for general room lighting where a more subtle level of illumination is required.
How do I calculate lumens 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.
How to figure out how many bulbs you need?
Divide the total number of lumens by the efficiency of the bulb and round up to figure out the number of bulbs you need:
How many lumens per square foot do I need?
In the first step of your calculations, you need to choose the type of area and activity that you want to illuminate. Simply select one of the options from the list, and our lighting calculator will automatically determine the optimal level of illumination in lux or foot candles (that is, how much light should be incident on the surface). Intuitively, ambient light in the bedroom shouldn't affect our preparations to sleep time and won't be as intensive as the light required for sewing.
How many lumens does a kitchen light bulb emit?
Then, choose the type of a light bulb you want to use. Let's assume you're using a standard bulb that emits 800 lumens for the kitchen and small LED lights that emit 200 lumens each above the counter.
What does BL mean in light bulbs?
bulbs = lumens / BL. BL stands for the number of lumens that a light bulb emits. You can usually find this number on the bulb packaging. It's a much better indicator of the bulb's luminosity than the wattage, as LED lights often need less power than regular light bulbs.
