SB QST @ ARL $ARLB098 ARLB098 1-year OK for RF lights ZCZC AG65 QST de W1AW ARRL Bulletin 98 ARLB098 From ARRL Headquarters Newington CT October 27, 1995 To all radio amateurs SB QST ARL ARLB098 ARLB098 1-year OK for RF lights The Federal Communications Commission has waived its rules to permit the General Electric Company to begin marketing an ''RF lightbulb.'' The Commission waived, at GE's request, FCC Rules Part 18 limits on the amount of RF energy that may be conducted into the electric power lines by RF lighting devices in the band 2.2 to 2.8 MHz. GE proposed marketing to consumers an unlimited number of RF light bulbs that comply with the conduction limits for non-consumer RF lighting devices in this band. (FCC rules already permit RF lighting devices used in commercial environments to place this signal level on the AC power lines). The FCC said that there has been ''no record of significant interference problems from the use of these devices in commercial environments,'' and also said that radio operations in the range 2.2 to 2.8 MHz ''are not normally employed or intended for reception in residential environments.'' GE was granted a waiver for one year, and the FCC reserved the right to revoke it if it determines that RF lighting devices operating under the conditions of the waiver create ''severe interference problems.'' Three years ago a California company, Intersource Technologies, promoted an RF-powered lightbulb that operated at 13.56 MHz and was designed, according to the company, to keep unintentional radiation to a minimum (a story appeared in August 1992 QST, page 49). A 25-watt RF bulb was said to generate as much visible light as a 100-watt conventional bulb. These bulbs were never marketed. The ARRL will obtain samples of the GE bulbs for testing as soon as they are available. ARRL Laboratory Supervisor Ed Hare, KA1CV, said that the new bulbs should not, if properly designed, create any more interference to Amateur Radio operations than fluorescent bulbs, dimmer switches, or other similar devices found in the home.
