How do I calculate how many lights I need in a 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. Then, add up the wattage in each bulb in each fixture to figure out how many light fixtures are needed. Here is the full answer.
How do you measure for LED lights?
Lumens are a unit of measurement for the brightness of a light in LED lighting. Watts, on the other hand, are a unit of measurement for the amount of energy in a light. The name lumen literally means “light,” which makes sense if you realize what this unit of measurement is. Lumens, in other words, are a measurement of how much light your LED light produces.

How many lumens do I need for a 12×12 room?
A basic rule of thumb is that a sitting room or bedroom will require approximately 10-20 lumens per square foot, but a bathroom or kitchen will require around 70-80 lumens per square foot. Simply multiply the square footage of the room by this amount to calculate the lumens required. This is the full article.
Where should I put LED lights in my room?
Where to put LED lights in your room
- Under cabinets or along toe kicks.
- Under shelves.
- Under the bed.
- Accent your stairs.
- Around your mirror.
- On your shelves.
- Above your closet.
- In picture frames.
HOW LONG CAN LED strip lights be?
12V DC LED strip longest length is 16ft (5 metres). 24V DC LED strip longest length is 32ft (10 metres). 24V Constant Current (CC) LED Strip is 65ft (20 meters). 120V LED Strip maximum length is 164ft (50 meters).
How do you calculate lighting?
Lighting Calculation – Summary
Calculate the amount of lumens you need. Multiply the area in square meters by the lux, or the area in square feet by the footcandles. Work out how many bulbs you need. Divide the number of lumens by the number of lumens delivered by each bulb.
How is light fixture spacing calculated?
Divide the total length of the row by the total number of lights in the row to determine the spacing between lights. Divide the spacing between the lights by 2 to determine the distance between the wall and the first light.
How are LED downlights calculated?
We always start by dividing the height of the ceiling by two. For our example example if you have a room that is 10 square meters you can use 4 x 5W LED down lights or 3 x 9W LED down lights.

Is 3000 lumens too bright?
3000 lumens is a good level of light for LED, CFL or incandescent lighting. It’s suitable for recessed lighting, downlighting, up lighting and within pendants.
How do you measure ceiling lights?
In general, we recommend that the light is 3″ tall for every foot of space between the floor and ceiling. You can find this number by multiplying the height of your ceiling (in feet) by three. For example, if your ceilings are 10′ high, your chandelier should be 30″ tall (10 x 3 = 30).
How many watts of light do I need per square foot?
An average LED lighting system draws about 32 watts to serve 1 square foot of grow space. The wattage in a grow room could be amplified up to a maximum of 50 watts per square foot. Going beyond that amount would create a too strong indoor plant light intensity, which could stunt the growth of your plants.
How many lumens is 100 square feet?
Determine the needed lumens
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 800 lumens very bright?
Lumens is the unit measurement of brightness, with 1 lumen equalling the brightness of 1 candle, so 800 lumens has the brightness of 800 candles. 800 Lumens is a good level of light for LED, CFL or incandescent lighting.
Should I put LED lights on floor or ceiling?
If you want more of your wall lit up, place the strips around a foot below the ceiling to allow enough space to glow upwards. The most ideal way to install LEDs is where their LED individual diodes are not jarringly visible and are hidden while preventing the harsh glare given off the lights from your eyes.
Are LED lights safe for bedroom?
And if you are wondering: Are LED lights safe to leave on in a child’s bedroom? The answer is YES but only if the fixture is a low-intensity (dim), warm temperature LED light.
How do you hide LED strips on the ceiling?
LED Strip Cove Lighting Install RGBW Tutorial
Is it okay to leave LED lights on all night?
To put it simply, well-manufactured LED lights are extremely long-lasting and can be left on 24 hours, 7 days a week. This is because, unlike conventional types of light, LEDs produce minimal amounts of heat, which means they are unlikely to overheat or set on fire.
Do LED strip lights use a lot of electricity?
An average LED strip light consumes roughly 7 to 35 watts. This wattage is highly dependent on the specific product, as more energy-conscious strip lights require very little electricity while bright, fully-featured lights can use almost as much electricity as a conventional bulb.
Are LED strips enough to light a room?
LED strips could certainly light up a room, but they’re unconventional. I think to get good light coverage, you’d have a few strips in the middle of the ceiling.
How do you calculate watts per square foot?
Divide the wattage consumed in the room by its area in square feet to calculate watts per square foot. In our example, 650 watts divided by 192.89 square feet is 3.37 watts per square feet.
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 many LED ceiling lights do I need?
A common rule of thumb is one recessed light for every 4 to 6 feet of ceiling space. Typically, fixtures should be placed 24 inches from a wall or cabinet with 2 to 5 feet of space between them.
How do you calculate spacing criteria?
You can calculate the spacing criterion you want by using Spacing Criterion = Spacing ÷ Mounting Height. Illuminate your walls by placing your recessed lights half the distance from the walls as they are from each other.
How far apart should 6 inch LED recessed lights be?
Generally speaking, recessed lights that are four inches in size should be placed four feet apart. Six-inch lights should be placed six feet apart. In other words, the diameter of the lights equals the space between them.
What size downlight do I need?
We recommend a downlight with a power consumption of 10-13W for ambient lighting in homes with ceiling heights of 2.4M to 3.2M. In light output terms (lumens and lux), these downlights will generally have a range of lumen output from around 700 lumens to 1100 lumens.
How many downlights do I need hallway?
The general consensus for selecting the number of downlights required is as follows: Step 1 – Measure the square footage of the room by multiplying its width by its depth. Step 2 – Multiply this square footage by 1.5. This will give you a guideline for the total wattage required to light the space.
What size recessed lights do I need?
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.
