There are many factors in LED signs that operators and owners need to know. Additionally, these elements will largely determine what should be displayed in an establishment. Here are some of the most common terms you will encounter should you purchase a LED sign or already own one.

1. 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 op…
