"During the design process," Wett says, "be sure to evaluate requirements such as visibility—how far away does the sign need to be read—so you can deter- mine what size letters are needed. Also review color contrasts. Are you mounting red letters onto a brick wall, which ends up being unreadable? Does the design allow enough space between letters, so they are readable from the side, espe- cially if they are deeper letters?" If sign makers are new to this process, there are ways to receive assistance. "Most LED module manufacturers provide either an online layout service or do in-house layouts for the sign com- panies that can help with these consider- ations so the best choice for the proper LED can be made," says Foreman. In many instances, it is the lighting that will ensure the success of a sign. Lighting the Way "While one may define 'successful' in a number of ways, I always like to think of a successful project as one that meets or exceeds the expectations of the cus- tomer," Wett says. Most end users, however, are not experts in LED lighting, so it's safe to assume they will lean on the sign maker or LED manufacturer for advice. "Important factors to consider for halo-lit signs are the mounting substrate and distance the letters are pinned off that surface," suggests Eppert. "The dis- tance you mount a halo lit letter from the substrate has a significant effect on the type of halo generated. A shallow distance promotes a tight isolated halo. A wider distance promotes a wider wall- washing halo." Foreman agrees that mounting dis- tance is a factor. "In considering the depth," he says, "the lumen output and the beam angle of the LEDs are most impor- tant. In a shallower application, one-and- a-half inches to three inches deep, a wider beam angle helps to spread the light better and avoids hot spots at the face. This holds true also when you go from a five-inch depth to let's say an eight-inch depth. The deeper the letter, the more lumens you need at the light source." The lighting effect is impacted by a variety of elements. Others include the sign face, backing and material finishes. "A glossy or highly reflective service is going to act like a mirror making the backs of the letters visible," Eppert says. "If a clear Lexan back is used, you will be able to see the LED modules in the background. To alleviate the problem, you can either modify the background to a matte finish, or if that is not pos- sible, use a white Lexan back instead of clear."
