Lighting the Surfaces the Daylight Already Reaches

A method that starts a lighting scheme from an observation rather than a fitting list: note which surfaces daylight reaches through the day, then put the electric layer on those same surfaces so the room's character carries into the evening.

Where this idea works

Where this idea works

Contexts this direction tends to suit — and, honestly, where it may not.

  • Rooms whose daylight can be watched for a while before the scheme is fixed
  • Refits where fitting positions are still open questions
  • Owners who like how a room looks by day and want that feeling after dark
  • Spaces with a distinct, directional daylight character

Where it may not fit

Where it may not fit

  • Rooms with almost no daylight to observe
  • Decisions that have to be made before the space can be occupied or watched
  • Schemes led entirely by task requirements that daylight has nothing to say about

Planning

Planning considerations

  • Watch the room across a day and, if there is time, a season, because daylight moves and one afternoon is not the room
  • Record which surfaces are lit and which stay in shade, since the shade is as much of the character as the light
  • Task needs still have to be met, so this method sets the ambient character rather than replacing the task layer
  • Fitting positions follow from the observation, which means observing before first fix rather than after it

Layout

Layout considerations

  • Aim the electric layer at the same walls and surfaces daylight reaches, rather than at the centre of the room
  • Leave in shadow the areas that are in shade by day, so the room keeps its depth after dark
  • Consider the direction daylight arrives from and whether an electric source can plausibly imitate it
  • Check the effect from where people actually sit rather than from the doorway alone

Materials & finishes

Materials and finishes to discuss

Named generically as starting points to discuss with professionals — not specifications, and not priced.

Consider:Wall-wash and grazing fittingsConcealed linear sourcesTable and floor lampsDimmable drivers and controlsMatte surfaces that hold a soft wash
  • Fittings chosen for one particular surface are hard to repurpose when furniture moves
  • Dimming components and controls date faster than the fittings they run

Maintenance & durability

Maintenance and durability questions

  • Washing a wall reveals every mark and patch repair on it
  • Aimed fittings drift and need re-setting after redecoration

Professional review

What to ask a qualified professional

Bring these questions to a designer, contractor or the relevant qualified professional or authority.

  • Which surfaces does daylight reach in this room, and at what times of day?
  • Which areas stay in shade, and should they stay that way after dark?
  • Where should fittings sit to light the same surfaces the daylight does?
  • What task light is still needed once the ambient character is set?
  • Can this observation be made before the electrician's first fix, and would a designer work from it?
