Extra section 2Maintenance checklist for LED signs in Chennai weather
Before installation
Ask how the SMPS will be protected, where service access will be kept, how water entry is reduced and whether cable routing is neat. This prevents repeated opening of the board later.
After installation
Clean acrylic gently, inspect flicker early, avoid pulling external wires and report any water marks quickly. Good maintenance extends LED and acrylic life.
For outdoor signage, environmental care and disposal should also be practical. Businesses can refer to TNPCB for state pollution-control awareness while planning large signage upgrades.
