recessed light calculator

Formula: total sq. footage x 1.5 = total wattage needed. Total wattage divided by 60 watts (or whichever wattage you select) = total amount of recessed can lights. Example: 240 square foot room x 1.5 = 360 divided by 60 (the bulb wattage I’d like to use) = 6 recessed lights needed.

How far should 6 inch 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.

How many inches apart should recessed lights be?

Follow the ceiling height rule of thumb.

To determine how far apart recessed lighting should be in bedrooms, kitchens and living rooms, divide the height of the ceiling by 2 and use that as your light spacing.

How many LED recessed lights on one circuit?

When it comes to LED and CFL bulbs used in recessed fixtures, we have mentioned that they produce light that is similar to a 60W incandescent bulb. The inrush current for LED lights is usually 20 amps for 240VAC. Therefore, a 15amp circuit can safely accommodate 180 or more fixtures using LED or CFL bulbs.

How many recessed lights do you need per square foot?

A common rule of thumb is that you use one recessed light for every 4 to 6 square feet of ceiling space. Doing so provides even, overall illumination. This is an important rule to keep in mind when you are going to rely exclusively on recessed ceiling lights to illuminate your kitchen.

How many can lights in a 20×20 room?

If you have a center light fixture, you should be able to use 4 inch line voltage cans or low voltage for supplemental lighting. I would go with at least 8 three inch cans for a 20 foot room.

How do you calculate the amount of light needed in a room?

Multiply your room square footage by the footcandle requirement. For example, a 100-square foot living room, which needs 20 footcandles, will need 2,000 lumens. A 100-square foot dining room, which needs 40 footcandles, will need 4,000 lumens 2 (see PDF and complete footcandle index).

How do you calculate spacing criteria?

Every manufacturer provides a maximum spacing criterion, which is a ratio to help determine the maximum distance you can put between each light. This number, which is usually between 0.5 and 1.5, is multiplied by the ceiling height in order to determine the maximum distance allowed for each light.

How many recessed lights do I need in my kitchen?

Install one recessed light for every four to six square feet of ceiling space. Though recessed lights may look small, together they provide strong, consistent light coverage across a whole room.

What is the difference between can lights and recessed lights?

A general rule of thumb you can go by is around 1 downlight per 1.4m2 of coverage at an average roof height for an adequate cover of light.

How many LED lights can I run on a 14 2 wire?

You can load 2,400 watts onto your 14-gauge wiring for a 120-volt circuit.

How many LED lights can I put on a 20 amp circuit?

Maximum Lights Per Circuit

Technically, you can install 13 outlets or lights on a 20-amp CB, but you can only put ten lights per circuit due to the 80% rule of maximum continuous load.

How many LED lights can I put on a 15 amp circuit?

Each CFL or LED bulb typically gives the same amount of light as a 60-watt incandescent bulb while drawing 10 watts or less, which is equivalent to a current draw of 1/12 amp. Thus a 15-amp circuit can safely control 180 or more fixtures that use CFL or LED bulbs.

What size recessed light for 8ft ceiling?

In an 8′ ceiling, a 4″ fixture can work well to provide kitchen countertop lighting. A 6″ downlight at that height will illuminate your breakfast table nicely. In a 10′ ceiling, you might want 4″ fixtures for area lighting, since the light will spread out more. A 7″ fixture makes a nice wall washer in an 8′ ceiling.

How many feet of LED lights do I need for my 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.

Can you have too many recessed lights?

It often seems that installing recessed lights is a cure all, but they cannot properly wash light upon walls and all dark corners, which would bounce reflective light into the room. In fact, using too many recessed light may leave areas of your room dark and may even cost you more on your electric bill.
