Custom LED Linear Luminaire Lighting Selection Guide
When selecting custom LED linear luminaires, compare profile width/height (mm), fixture length (cm), suspended/surface/recessed mounting, wattage and color temperature.
This guide explains what to look for when choosing products in the Custom LED Linear Luminaire Lighting category for modern offices, retail stores, showrooms and architectural ceiling layouts.
Profile cross-section (Width × Height) and mounting method
Architectural LED linear luminaires are classified by their extruded aluminum profile cross-section (such as 40×40 mm, 50×50 mm, 50×70 mm, 70×70 mm) and ceiling installation style. Exposed concrete ceilings use wire-suspended (pendant) or surface-mounted profiles, whereas gypsum drywall and acoustic grid ceilings use recessed flanged (trimmed) or trimless profiles.
Fixture length, wattage per meter and color temperature (CCT)
Standard lengths include 60 cm, 100 cm, 120 cm, 150 cm, 200 cm and 240 cm. Specify 4000K (neutral white) for productive office workstations and conference rooms, 3000K (warm white) for hospitality and lounges, and 6500K (cool daylight) for technical bays and display areas.

Frequently asked questions
What dimensions must be checked before ordering a recessed linear luminaire?
For recessed models, distinguish between the outer bezel width and the ceiling cutout width and recess depth so the fixture clears ceiling joists and sits flush against the drywall.
What prevents visible LED hot-spots on a linear luminaire?
Combining sufficient profile depth, high-density mid-power SMD LED boards and an opal polycarbonate diffuser blends individual diodes into a uniform, glare-free ribbon of light.
Can the suspension height of pendant linear luminaires be adjusted on site?
Yes, steel wire suspension kits feature spring-loaded clutch grippers that allow installers to adjust and level the hanging height easily during installation.
