LED Strip for Architectural Cove, Profile and Feature Lighting

COB and SMD strip for cove, profile and feature lighting: SDCM ≤3, CRI 90–95, 24 V long runs, constant-current options and project-level bin records.

COB LED strip installed in an aluminium cove profile casting an even wash of light across a plaster ceiling
COB strip at 480 chips/m in a 20 mm cove profile, no dot pattern.
Short answer

Architectural lighting specifications turn on colour consistency, dimming behaviour and serviceability rather than on price per metre. HFY LED supplies COB and high-CRI SMD strips at SDCM ≤ 3 with CRI 90–95, in 24 V runs up to 10 m from one feed and 50 m reels, and holds a bin record per project so replacement strip matches the installed installation years later.

Scope of supply in this sector

We supply strip and drivers to lighting designers, M&E contractors and fixture integrators. We do not design the lighting scheme, produce Revit families or take responsibility for lux levels on site — those sit with the lighting designer, and we will provide photometric files for their calculation.

Requirements

Colour consistencySDCM ≤ 3 across the whole project
Colour renderingCRI 90 minimum, CRI 95 for hospitality
Dimming0–100% with no flicker below 5%, PWM ≥ 1.5 kHz
Voltage24 V for runs above 5 m; 48 V for long perimeter runs
Rated lifeL70 ≥ 50,000 h at 45 °C ambient
DocumentationLM-79 report, IES file, bin record per lot

Materials and profiles for this sector

  • COB strip at 320 and 480 chips/m for reflected coves
  • SMD 2835 CRI 95 strip for indirect lighting in profiles
  • Aluminium profiles with opal or micro-prismatic diffusers
  • 24 V and 48 V constant-voltage drivers, DALI and 0–10 V dimmable
  • Constant-current modules for long runs with multiple feeds

Applicable standards

  • IEC 62031 for LED modules
  • IEC 62471 photobiological safety
  • LM-79 and LM-80 photometric reporting
  • EN 60598 for the completed luminaire
  • CE and RoHS declarations for all strip

Typical parts

  • Cove and cornice lighting in hotels and lobbies
  • Recessed ceiling perimeter lighting
  • Joinery and shelving integration
  • Wall-wash and grazer profiles on stone and timber
  • Stair nosing and handrail lighting
  • Backlit translucent panels and onyx features

Quality risks specific to this sector

These are the failure modes we see most often in this industry. They are listed because knowing them before design review is cheaper than discovering them at first article.

  • Mixing production lots in one continuous cove produces a visible tint step even at SDCM 3 — the fix is a single lot per elevation, ordered with 10% spare
  • Dimming below 5% reveals driver PWM artefacts: a 200 Hz driver flickers visibly on camera even when it looks steady to the eye
  • Sealing an aluminium profile with no ventilation raises the strip temperature 15–20 °C, which cuts rated life by roughly 40%

Compliance and capability questions

How much spare strip should I order for a project?

Ten percent, and from the same production lot. Spare strip matters less for replacement than for the last few metres of an elevation where cutting losses accumulate; ordering spares from a later lot is the most common cause of a visible colour step six months after handover.

Can you supply IES files for lighting design?

Yes, for each LED type and profile combination we produce, measured on the integrating sphere. For a custom profile the IES file describes the bare strip, not the profile, so the designer should apply the diffuser loss of 8–15% in their calculation.

What CRI do I need for a hotel lobby?

CRI 90 with R9 above 50 is the practical minimum for interior hospitality work; below that, skin tones and timber read grey. CRI 95 costs 10–15% more per metre and is justified where the lighting is the design feature rather than the backdrop.
