Start with the perimeter of the room and then work your way inward. (and don’t worry about a symmetric RCP!!!)

WHERE TO START

AVOIDING LIGHTING PROBLEMS BEFORE THEY ARE INSTALLED

Do I need the fixtures to be soft and wide (distribution) or tight and directional?

WALL WASHING vs. ADJUSTABLE ACCENTS

  • Wall Washers
  • Wall washing is a very effective way of making a room feel open and

bright due to the reflected (indirect) lighting it provides into a space.

  • Are you really trying to “wall wash” or are you trying to highlight

artwork?

  • Spacing criteria is very easy…essentially a 1:1 ratio of distance out from a

wall and distance apart…can be stretched to 1.5:1 if needed.

  • However, it requires (what looks like) more fixtures to do it correctly.
  • Based on “normal” framing, this means fixtures would be placed 32”

apart from each other…every other ceiling joist bay

SLIDE 28
  • Wall Washers
  • 24” out from a wall…fixtures can be placed anywhere from 24” to 32”

apart from each other.

  • 36” out from a wall…fixtures can be placed anywhere from 36” to 45”

apart from each other.

  • Any farther from the walls than 36”, wall washers are not recommended

because the light level drops off precipitously.

  • Adjustable Accents
  • Adjustable accents are the most versatile fixture type…
  • Can be used as downlights, “wall washers” or to specifically highlight

artwork/objects.

  • Using adjustable accents in most locations can be very helpful to deal

with changes in use of room or unexpected ceiling conditions.

  • Does the adjustability happen inside the fixture or does it stop the fixture

from really being a recessed light?

  • Internal adjustment vs. gimbal ring

ISSUE #3: DIMMING LED FIXTURES AND LAMPS

AVOIDING LIGHTING PROBLEMS BEFORE THEY ARE INSTALLED

AMERICAN LIGHTING ASSOCIATION CLC SEMINAR 09/24/18

slide-36
SLIDE 36
  • Explain the differences to Clients…LEDs are NOT incandescent

and will not “act” exactly the same as what they are used to…

  • Benefits of staying with a constant CCT as opposed to “warm

dim”

  • How low is low?
  • How to deal with flickering light sources
  • Is 5% actually 5% or is it 5% of “perceived brightness”
  • 5% OF 650 lumens is a lot different than 5% of 1100 lumens

SLIDE 37

DIMMING LED FIXTURES AND LAMPS

  • ALL LED fixtures and light sources dim differently…some good, some

bad

  • Different “languages”…ELV, MLV, Forward Phase, Reverse Phase, 0-10V
  • Dimmer style MUST match what is required by the LED manufacturer
  • Will it flicker? Will it hum?
  • If it’s not tested or listed, can you use it?
  • When in doubt, read the dimming performance listed by the fixture or

LED manufacturer.

COVE LIGHTING

AMERICAN LIGHTING ASSOCIATION CLC SEMINAR 09/24/18

slide-40
SLIDE 40
  • Cove lighting is only successful if minimum distances are

provided in the architectural details…

  • Most critical distance is the shortest distance from the cove light

to the first surface it hits (wall or ceiling)

  • The greater the distance, the better the spread and the better

the effect.

  • Smaller distances (6” or less) will never provide a soft, even

effect

  • Determine whether the lighting is meant to be a soft, low level

accent or a “performance” cove.

slide-41
SLIDE 41
  • Performance coves are typically going to…
  • be larger rooms with higher ceilings
  • have greater distance between fixture and ceiling
  • require higher lumen outputs (600 lumens per foot)
  • be line voltage cove lights with integral drivers

  • Accent (only) coves are typically going to…
  • be smaller rooms or areas with lower ceilings
  • have minimal distance between fixture and ceiling
  • require lower lumen outputs (200-300 lumens per foot)
  • be low voltage cove lights with remote drivers

slide-43
SLIDE 43
  • Always consider a 1:1 ratio…
  • Distance from fixture to back wall of cove must be equal to or

greater than the spacing between lamps (or ends of fixtures).

  • Think about how possible is to install the fixtures or access

them

  • Just because something is LED doesn’t mean it does not have

to be accessed at some point
