Surface-mounted linear lighting for ceilings and walls with nothing to recess into
When there is no ceiling cavity, as with exposed concrete, open structure or finished walls, surface linear gives the same clean line of light with simpler installation.
Short answer
Use surface-mounted linear lighting when there is no ceiling cavity (exposed concrete, open structure, existing finished ceilings) or when the fixture must mount to a wall. It fastens directly to the surface with clips or brackets, and power comes through the back or end of the fixture from a junction box. Specify the profile size, how the power feed is concealed, lumen output, CCT, CRI, lens, voltage, driver location and dimming.
Key takeaways
- No plenum needed; installs after finishes.
- Plan feed locations so conduit is not exposed along the run.
- Profile depth sets how much the fixture projects from the surface.
Where surface linear fits
| Situation | Why surface linear |
|---|---|
| Exposed concrete ceilings | Nothing to recess into; clean line on the slab |
| Open structure / industrial interiors | Mounts to unistrut or deck with brackets |
| Retrofits into finished ceilings | No cutting; faster install |
| Walls, stairs, corridors | Wall-mounted runs for vertical or accent light |
Specification checklist
- Surface type and fixing method
- Profile width and depth (projection)
- Feed method: back-feed from junction box or end-feed
- Run lengths and corners
- Lumens per foot, CCT, CRI, lens
- Voltage, driver location, dimming protocol

Frequently asked questions
How is power fed to surface linear lighting on a concrete ceiling?
Usually from a junction box cast into or mounted on the slab, entering through the back of the fixture so no conduit runs along the ceiling. Where that is impossible, feeds come from the end of the run.
Can surface linear lighting be used on walls?
Yes, as long as the product is designed for wall mounting in the orientation used. Check the cut sheet.
