LED is a light source meaning a signboard that emits light via electricity. This is an excellent tool for offices that works after dark. Or the eatery places, clubs, bars, or hospitals. The only downside that we see here is the upfront cost as these information boards will be running on electricity. Some product even runs hot with higher wattage that they need a heatsink. There is another alternative available in the marketplace, and that is neon sign boards. It gives much warmer light than LED, but its maintenance cost is higher.
