The Alpha series of digital signage is manufactured by Adaptive Micro Systems, Incorporated (does not sell directly to the public) located in Appleton Wisconsin (www.AdaptiveDisplays.com). All signs are warranted by the manufacturer, plus in some cases an additional warranty by the distributer.
LED - Light Emitting Diodes (LED) draws very little energy while creating a very bright light.
The LED light is not only brighter than a standard incandescent light, but is a truer white light. Color options may also enhance the your signs brightness. Since the background of most LED signs is black, then the red LEDs will probably not show as brightly as the amber LEDs. Although, the red will probably be an eye catcher more than any other color.
LED - The LED bulb averages 10,000 hours of continuous operation.
Placement is the biggest consideration. Not too high, yet not too low. Your placement will be dependent also on electrical access (electrical outlet or wiring) and administrator access if the information is changed regularly. Another placement consideration is the distance from the viewer, which incompasses character size, brightness and resolution.
Administrator access will be a big consideration if the information is to be changed on a regular basis. If you are using the handheld keyboard, then programming is accomplised very easily while positioned in front of the sign. On the other hand, if you are using a wired network connection, then it is a matter of which computer will be designated as the Administrator and wiring that computer to your digital sign.
Your sign will need to be visible from a maximum distance. This "maximum distance" will be predicated on character size, resolution and brightness. It also might be added that color can also play as an important consideration. Even though an amber character may show as bright as a red character, it might not attract the attention as quickly. So, needless to say, there are several factors to consider when purchasing a digital sign.
