Robert, I got an email from Scott Booth at Halff on this very subject. Ironically, Mike Romanowski with Halff is working on an intersection design for us and has the most current ILSN sign design. I believe it is the LED version. If you need any additional information, just let me know. Thanks, Clay Barnett, P.E. Town Engineer Town of Addison 16801 Westgrove Drive Addison, TX 75001-2818 Office: (972) 450-2857 From: Robert Kotasek [mailto:rkotasek@thecolonytx.gov] Sent: Wednesday, July 07, 2010 10:49 AM To: Clay Barnett Cc: Ron Hartline Subject: Request For LED Illuminated Sign Standards Clay, Per our phone conversation earlier, I was wondering if you could send me the design standard drawings that you mentioned that Addison will be using as a good go-by for LED Illuminated Street Signs. From talking to Robin in your department, it appears that Addison currently is using florescent bulbs for illumination, but will be switching to LED’s for future street sign illumination, as needed. He was able to answer my question I had on general maintenance for your city’s existing illuminated street signs. I appreciate your time on answering my questions on your city’s street signs, Thanks, Robert Robert Kotasek Staff Engineer City of The Colony 6800 Main Street The Colony, TX 75056 Phone: 972-624-3148 Fax: 972.624.2317 Email: rkotasek@thecolonytx.gov
