NPSTC has been monitoring reports of interference from LED and fluorescent lighting system ballasts which have caused disruption to public safety land mobile radio systems.

In 2013, the FCC issued an order directing one manufacturer to make some changes to their LED lighting transformers after complaints were received about interference.

More recently, some public safety agencies have reported interference from LED lights installed on agency radio towers, from fluorescent lighting installed at an incident command post, and from commercial buildings with large lighting systems.  NPSTC has created this questionnaire to gather additional information from public safety agencies on the extent of these problems.

Information from the questionnaire will be reviewed to see if NPSTC should petition the FCC to update existing rules that govern the use of these lighting systems and similar electronics.  NPSTC is also working with the American Radio Relay League (ARRL), which has reported such interference to amateur communications.

The LED Interference Questionnaire  will be open until Friday, February 13, 2015. We appreciate your attention to this survey.  We will provide you with a copy of the results once they are compiled.
