What is linear lighting?

Linear lighting is a category of LED luminaire built as a continuous straight or modular run of light, rather than a single point source. Common formats include suspended profiles, recessed trimless , surface-mounted and flexible LED tape - used to deliver even, glare-controlled illumination across offices, data centres, galleries and other commercial interiors.

 

Unlike downlights or spotlights, linear systems can run continuously for metres at a time, be joined at corners, and be finished in bespoke lengths, colours and mounting styles. That flexibility is why linear lighting has become the default choice for modern Category A and Category B office fit-outs.

FAQ

Frequently asked questions about linear lighting

What is linear lighting?＋
Linear lighting is a category of LED luminaire built as a continuous straight or modular run of light, rather than a single point source. Common formats include suspended profiles, recessed trimless channels, surface-mounted and recessed profiles, delivering even, glare-controlled illumination across commercial interiors.
What is the difference between linear lighting and a downlight?＋
A downlight is a single point source lighting one spot below it. Linear lighting is a continuous or modular run of LEDs that can extend for metres, be joined at corners, and be finished in bespoke lengths and colours, giving far more even light distribution across large or open-plan spaces.
What are the different types of linear lighting?＋
The main types of linear lighting are suspended profiles (direct, indirect or both), recessed and trimless channels, surface-mounted, wall-mounted linear, and flexible LED tape. Each suits different ceilings and effects, and bespoke curved or geometric profiles are also available for feature lighting.
What is suspended linear lighting?＋
Suspended linear lighting hangs from the ceiling on cables or rods, sitting below the soffit. It can be direct (light down), indirect (light up onto the ceiling) or direct/indirect, and is widely used in offices and receptions to deliver even, low-glare light across open-plan spaces.
Is linear lighting suitable for offices?＋
Yes. Linear lighting is the default choice for modern Category A and Category B office fit-outs. It supports CIBSE LG7-compliant direct/indirect schemes and glare-controlled UGR19 output suited to screen-based work.
What colour temperature is best for office linear lighting?＋
Most UK offices use 4000K (neutral white) linear lighting for a balanced, productive feel, while 3000K (warm white) suits hospitality and breakout areas. Tunable White options let the colour temperature shift through the day to support circadian, human-centric lighting schemes.
Is linear lighting suitable for listed or heritage buildings?＋
Yes. Made-to-measure linear profiles can be specified to sit sensitively within Grade II listed and conservation-area interiors, as demonstrated in 299 Lighting's Walworth Town Hall restoration in London.
Can linear lighting be controlled with DALI or Casambi?＋
Yes. 299 Lighting's Rio family and other linear ranges support both DALI and Casambi control protocols, allowing dimming, zoning and scene-setting to be integrated into a building's existing lighting control system.
Can linear lighting be used for emergency lighting?＋
Yes. Many linear lighting profiles are available with an integrated 3-hour emergency option, allowing the same fitting to provide both general and emergency illumination. This keeps ceilings clean and simplifies compliance with UK emergency lighting requirements on commercial projects.
How much does linear lighting cost?＋
The cost of linear lighting depends on length, output, finish and control system, so commercial projects are quoted individually rather than sold at a fixed price. 299 Lighting provides free specification advice and a tailored quote based on your drawings, ceiling type and required light levels.
Who installs commercial linear lighting in the UK?＋
299 Lighting has specified linear lighting across more than 3,500 UK commercial projects, offering consultation, lighting design, product specification and project management from concept to completion. They can be reached on 020 3773 7530.
