Outlets are not circuits. What to ask a venue before LED wall load-in – dedicated breakers, voltage, distro, hotel “dedicated” traps, and when a generator is the honest plan.

Screw, magnetic, or front-locking LED modules – how each holds the module to the cabinet, which scenes fit rental and fixed walls, and the RFQ lines that make “front maintenance” comparable.

What LED factory aging / burn-in actually means before shipment – hours, R/G/B/white/gray cycles, pass criteria, and the evidence pack buyers should write into the RFQ so “QC OK” is countable.

Work out your LED wall’s native resolution from cabinets and pitch, fit it into a 1080p or 4K input, and build a pixel map so content plays 1:1 — no stretch or crop.

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.
