Two rental LED quotes can both say “fast install” and still diverge by hours at the dock. The system drivers that move load-in time, and the RFQ lines that make “fast install” countable.
Two export LED quotes can both say “CE / FCC ready” and still stall at customs, venue or insurer review. How to ask for model-matched LVD, EMC Class A/B and FCC test reports instead of cover certificates.
A walkable LED floor is a load path first and a pixel pitch second. What kg/m² really means, distributed vs wheel load, decorative tiles vs video floors, 1.5T/2T planning bands, and wall-to-floor 2-in-1 RFQ lines.
Factory calibrated is not a finished wall. Spec D65, gamma, warm-up, and coefficient restore after module swap — what to write on the RFQ before tools arrive.
The quote says 3% spare modules and hot-swap ready. Spare % is fleet inventory math; hot-swap is a cabinet design claim. Honest bands, companion kits, and when to verify.
The quote stacks 3840Hz, 1/32 scan, and 60 fps like one ladder. They are three clocks: frame rate is content, refresh is PWM redraw, scan is row multiplexing.
The quote says “HDR-capable.” The show file is SDR. Or the camera is HLG and the wall is still set for PQ. That mismatch is how rental and live buyers pay for a sticker and inherit clipped highlights.
The quote says “weatherproof.” The datasheet says IP54. The stage is open to the sky. That mismatch is how outdoor and rental buyers inherit wet receiving cards and a season of board swaps.
The wall looks perfect at doors. Mid-set, a vertical stripe goes black for a second, comes back, then does it again. Or the whole surface dies while the processor still shows content on its preview. Someone says “we bought dual backup.” Someone else asks which dual.
Pixel pitch and brightness get the brochure pages. Service direction decides whether your team can actually fix a dead module at 2 a.m. without tearing down cladding.
