05FAQ
How should the power layout for channel-letter modules be planned?
Total the series-parallel module count for load with headroom, and watch wire gauge and voltage drop on long trunk runs; for large letters, supply per cavity to limit the blast radius of a single fault.
What IP rating for outdoor signage?
For exposed outdoor use, potted IP67 types with waterproofed terminations; semi-enclosed light boxes can use IP54 with ventilation and heat dissipation assured.
Why does power-supply lifetime matter for signs?
Signs run long hours daily (12–16 h is typical); supply lifetime and lumen decay directly drive service frequency — we design selection for long-cycle reliability.
Constant-voltage or constant-current for LED strips and channel letters — and how much headroom?
LED strips, modules and channel-letter sources are constant-voltage loads — keep one voltage grade (12V or 24V) per run. Load supplies to 80% of rating and split large installations into zones; choose natural-convection types for sealed light boxes, semi-potted rainproof types for outdoor heads and slim profiles for narrow coves.
