LED 101 / Buying
How to read an LED quote
A useful quote lists pitch, brightness, refresh, IP, certification, spare kit, structure, and who owns control. Diagonal inches alone are not enough.
Treat an LED quote like a construction package, not a TV flyer. If a line only says a diagonal size and a brand, ask for the rest before you compare prices.
Display. Pixel pitch, cabinet model, finished width and height, native resolution, brightness (typical and peak), refresh rate, colour processing, indoor or outdoor IP rating, front or rear service, and the certification mark on the exact model. See Wall size and resolution, Brightness, Filming and livestreaming LED walls, IP rating and outdoor LED, and Electrical certification in Canada.
Application extras. Gym impact design (mask, module lock, trim) is not the same as fine-pitch COB for a lobby. Say which room you are buying for. See Impact-resistant LED for gymnasiums and COB LED.
System. Processor model, cabling (copper or fibre), media player or scoreboard PC, room control integration, and power shutoff. See Content and control.
Install. Structure and engineering, electrical circuits, outdoor enclosure if any, lift time, commissioning, and training. Structure and power are where late change orders hide. See Mounting and structure and Power and heat.
Aftercare. Warranty length and what voids it, spare module kit from the same batch, response time, and who stocked the spares. See Service and spares and Batched modules and calibration.
Compare quotes on the same pitch, brightness class, service method, and spare package. The cheapest diagonal often drops structure, circuits, or matching spares into “by others.”
