18 • March 2019 • S I G N & D I G I T A L G R A P H I C S ELECTRIC SIGNAGE "The concept was simple but elegant —develop a product in which the LED carrier substrate fits directly into a T-12 socket," Vincent continues. "The power supply is separate, allowing for a highly reliable commercial power supply to be used versus the low reliability of self-bal- lasted LED drivers. The product there- fore can be field cut and any range of LED string modules can be placed onto the substrate." Of course, not all sign shops follow the same protocol. Some have product preferences, others specific methods. And with that comes different ways to approach a retrofit. "The experience and organizational structure among sign-service provid- ers varies vastly. Because of that, many of them have different preferences for how they go about doing lamp replace- ments," explains Kerber. "One way is for sign companies to use their own labor to apply high-quality channel letter mod- ules, like the Phoenix PF-3120 offered by HanleyLED, to an ACM baffle that is UL Recognized for use in electric signs, such as MAX-METAL, or to one of their in-house aluminum extrusions. They will then mount these into the sign cabinet by riveting it into existing structure in the sign." As Kerber mentions, HanleyLED is exclusively provided by Grimco. Among the most popular retrofit options are Concorde Bar and the WS-6600 Double- sided Wingspan Module. Concorde Bar "mounts directly into fluorescent lamp sockets or can be mounted directly to the raceway with their 'Speed Spring' brackets," Kerber states. "The brackets zip quickly into the raceway, and the Concorde Bar mounts to the Speed Spring bracket like an HO socket." Another product on the market is Principal LED's Stik (mentioned earlier) that "is 100 percent aluminum extrusion and our Tap Out modules are housed in an IP67 over-molded housing, taking the amount of breakage on a truck or in the field to zero," says Vincent. Qwik Mod 2 was used in these six-foot fabricated letters with Tap Out Stiks in the main cabi- net with flex face. Image courtesy of Mikal Harn, Comet Signs. PLED's Street Fighter Standard was used for the airport logo and Street Fighter Sidekick on the wings. Tap Out Stiks were used over the cabinet, replacing fluorescent lamps.
