Extra useful sectionMaintenance plan for mist, drizzle and daily glow
Monthly visual check
Check whether all letters glow evenly. One dim area can indicate loose wiring, moisture entry or module failure. Early checking keeps repair simple.
Cleaning routine
Dust, mist residue and bird marks reduce brightness. Clean the face gently without scratching acrylic or forcing water into edges.
Seasonal electrical check
Before heavy rain periods, inspect cable entry, SMPS ventilation and earthing. A planned check is cheaper than emergency repair after failure.
When you order a LED sign board near Kotagiri, ask for written warranty details: 5–7 years on LEDs, 2 years on SMPS, 10 years on acrylic and 12 years on ACP/stainless steel where applicable.
