The latest generation of LED digital message signs are extremely bright and they need to be regulated but the user in order to prevent distractions for night time drivers.
West Cost Signs recently installed a double faced 16mm Clearview LED sign in Clearwater, FL on busy Hwy 19. The sing looks great during normal daylight hours but is much too bright in the evening. Fortunately, the sign is equipped with an auto dimmer which is a photocell that detects the outside ambient light and dims or brightens the sign accordingly. The sign now runs at 30% brightness during the evening and about 80% brightness during the day.
The benefits of using the auto dimmer feature on your sign included 1. Fewer motorist complaints 2. Less power usage 3. extends the life of the digital led sign.

Have you ever noticed some signs are much brighter at night than others?
Brightness could be a factor of several things:
1. Daylight Lamps vs. Cool White lamps. More and more of today's signs are built using daylight spectrum lamps instead of cool white lamps. Daylight or DA lamps display a broader spectrum of light and there fore, appear brighter at night. Cool white lamps have a tungsten tinge which makes them appear beige or light brown in comparison to daylights. Ask your sign company to change out your lamps to daylights - the cost is not significant and you'll be shocked at the difference.
2. Sign faces tend to fade or get color damaged over time. Regardless of how bright your lamps are, it's possible that your sign face has simply faded or has been damaged by the sun. This will also cause your sign to appear less bright. Have your sign service company quote new faces which will give your sign a great facelift.
3. Algae buildup. After several years signs often develop algae growth on the inside of the faces. That growth restricts the light that shines from inside the sign. Have your sign service company clean the faces on...

When purchasing an LED Message Center, you're often faced with options that include different "pixel pitches". Don't get confused....pixel pitch basically describes the density of the LED pixels on the message system. The more dense, the higher the resolution and the more data you can display.
When talking about pixel pitch, please remember that the lower the number, the higher the screen resolution. For instance, a 14mm screen has much more resolution than a 20mm screen. The reason for this inverse relationship is that pixel pitch is the measurement from the center of one pixel to the center of the neighboring pixel on your screen. The smaller the distance, the tighter the resolution.
This chart will give you some general ideas on pitch.
