Degradation – Degradation is when a LED sign begins to lose 20% of its brightness, which often occurs during the first 2 to 3 months of usage, or a total of 2000 hours of use. A LED diode’s degradation after that slows down, so slow that it is unnoticeable to the human eye, and eventually dies after 100,000 hours of operation. 2. LED Diode Density – The density of LED diodes reflects the general performance of a LED sign. Generally speaking, the more LED diodes per unit area, the brighter a LED sign will
