LED & Cove Lighting

Concealed linear LED that lights the architecture instead of the room.

Overview

LED & Cove Lighting — what's involved

Cove lighting works by hiding the source. A linear LED run set into a recess throws light up and across a surface, and what you see is the lit plane rather than the fixture — which is why a coffered ceiling with cove lighting reads as architecture and a coffered ceiling with downlights in it reads as a ceiling with lights in it. The beam ceiling photographed above is that effect: warm LED tape concealed in the recess beside each beam, washing the panels between them.

Getting it right is mostly about things that are invisible in the finished result. The tape has to sit far enough back that the individual diodes cannot be seen from any normal viewing angle, the driver has to be sized with headroom and located somewhere accessible, and the dimming has to be matched or the whole run shimmers. Electric Shock coordinates this with the carpenter or drywall contractor while the detail is still being built, because the recess dimension is the one thing that cannot be changed afterwards.

Included

Concealed and linear LED work

  • Cove, tray, coffered and soffit lighting in ceilings and around bulkheads
  • LED tape in aluminum channel with diffusers, which removes the dotted appearance
  • Correctly sized drivers with headroom, located where they can be serviced
  • Tunable white and color-changing runs where the room justifies it
  • Stair, handrail, toe-kick and niche lighting
  • Exterior soffit and architectural linear lighting in wet-rated channel
  • Replacing failed or mismatched sections of existing tape runs
How it works

The LED & Cove Lighting process

  1. Design the detail with the trades

    Recess depth, the lip height that conceals the source, and the distance from tape to the lit surface all determine the result. We work these out with whoever is building the detail, before it is built.

  2. Specify tape and channel together

    Density, output, color temperature and CRI, in channel with a diffuser. High-density tape and a diffuser are what prevent the run reading as a line of dots.

  3. Place drivers where they can be reached

    Drivers are the component most likely to need replacing. Putting them behind a sealed ceiling to save an access panel is a decision someone regrets later.

  4. Install with correct feeds

    Runs are fed at the right intervals to avoid voltage drop along the tape, which is what causes one end of a long run to sit visibly dimmer than the other.

  5. Commission at night

    The run is dimmed through its full range and viewed from where people will actually stand, to confirm no source is visible and no flicker appears at the low end.

Why it matters

What you get out of it

  • Light without a visible fixture

    Nothing to see on the ceiling, which is the entire appeal — and the reason it suits coffered and tray detailing so well.

  • Soft, indirect, and easy to be under

    Bouncing light off a surface produces a diffuse wash with none of the glare of a direct source in your line of sight.

  • Built to be serviced

    Accessible drivers and channel-mounted tape mean a failure in five years is a repair, not a demolition.

Questions

LED & Cove Lighting questions

Still not sure? Send us the details and we'll give you a straight answer before anything is booked.

Why does my existing LED strip look like a row of dots?
Low-density tape, no diffuser, or the tape sitting too close to the lit surface — usually all three. High-density tape in an aluminum channel with a frosted diffuser, set back far enough, resolves into a continuous line of light.
Can cove lighting be added to an existing ceiling?
If there is already a cove, tray or soffit with a suitable recess, yes. If there is not, the recess has to be built, which makes it a carpentry and drywall job with an electrical component rather than an electrical job — worth knowing before you plan around it.
Why does my strip flicker when dimmed?
Almost always a driver and dimmer that were not specified as a pair. LED dimming compatibility is genuinely fussy, and matching the two at specification is far easier than fixing it afterwards.
