How to plan back-lit and halo channel letters
Halo lighting creates the visible effect by directing LED light toward the wall behind the letters. The spacing, wall texture, letter depth and mounting method all affect whether the final sign has a soft, even glow or a harsh hotspot.
Wall surface
A clean, matte surface usually shows a more even halo than a highly reflective or heavily textured wall. Review a facade photo and a physical finish sample where possible.
Standoff distance
The gap between the letter and wall controls the spread of light. It should be selected together with letter depth, LED placement and the desired effect rather than copied from another project.
Night-time contrast
Dark walls can make a halo outline stand out, while light walls may need a different brightness and finish. Check the sign at the actual viewing distance and lighting conditions.
Service access
Plan how the power supply, wiring and LED modules can be reached. Hidden lighting can still create maintenance issues if access was not included in the installation detail.
Proof and approval
Check the dimensioned proof for letter proportions, mounting height, standoff gap and light reference before production. The approved layout should also be checked against the real facade rather than a generic product photograph.
