Question: How To Layout Recessed Lighting

A good general rule for placement is to divide the height of the ceiling by two. The result is the amount of space to leave between each light. For example, recessed lighting spacing for an 8-foot-high ceiling would be 4 feet between each light. This will provide good spacing for general room lighting.

How far from the wall should recessed lights be?

If you plan to illuminate an entire wall or accent particular architectural features or pieces of art, the rule of thumb is to place your recessed light fixtures between 1.5 feet and 3 feet from the wall. If your fixtures are fixed, they should be placed a bit closer to the wall.

How do you calculate how many recessed lights are needed?

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.

Should you stagger recessed lights?

The typical rule is to place the lights the same number of feet apart as the bulb’s diameter in inches. So a bulb with a 4-inch diameter should be 4 feet away from the next light.

How far apart 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. In other words, the diameter of the lights equals the space between them.

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.

Does recessed lighting have to be symmetrical?

The General Lighting Layout The recessed lights should be aligned and equally spaced across the ceiling. Resist the temptation to place the lights according to objects in the room (such as furniture).

How many recessed lights can you put on one switch?

The main limitation on the number of recessed lights that a single switch can control is the rating of the circuit breaker controlling the circuit. Each incandescent or halogen 60-watt bulb draws around 1/2 amp, and therefore, standard lighting with a 15amp breaker can manage 30 lights.

Can you have too many recessed lights?

“It’s too bright in here.” The culprit: Too many recessed lights. Home builders, contractors—or hey, even you—can get a little overzealous when it come to how many recessed lights go into a space. And too many can leave a living room feeling like a lobby or a hallway feeling like a runway.

What size recessed light for 8ft ceiling?

When spacing recessed lights, use this general rule of thumb: divide the height of the ceiling by two to get the distance the lights should be from one another. For example, an 8-foot tall ceiling should have recessed lights spaced 4-feet apart.

How close can recessed light be to joist?

That said, a fairly standard recessed light should not be fitted so that any part of its assembly is less than half an inch from anything flammable — such as a timber joist — at the sides. A two-inch clearance from anything above the lamp is a typical minimum.

How many recessed lights can you 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 is spacing criteria in lighting?

The spacing criterion of a luminaire is an estimated maximum ratio of the luminaire spacing to the luminaire mounting height above the work plane for a regular array of that luminaire such that the work plane illuminance will be acceptably uniform.

Are recessed lights outdated?

The one reason why recessed lighting is timeless because they offer the flexibility to change the finishes later. You have a can in your ceiling that stays forever. However, the finish may become outdated and can be purchased in different colors and styles to suit your needs. You can change them as often as you like.

How do you calculate lighting for an area?

Lighting Calculation – Summary 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 many lights are needed in a room calculator?

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.Key Terms. Room Foot Candles Needed Bedroom 10-20 Hallway 5-10 Bathroom 70-80.

What is the difference between can lights and recessed lights?

Recessed lights, also known as can lights, are described as metal light housings installed in the ceiling for a sleek look that gives you back your ceiling.

How much area do LED lights cover?

The average LED grow light draws about 32 watts to cover 1 sq ft for flowering. Compare this to a typical HID fixture which rings in at 40 watts per square foot (assuming a 5′ x 5′ area, or 25 sq ft coverage area). Using an HID in a 4′ x 4′ will bring the power coverage up to 62.5 watts per sq ft.
