<h1>ARRL to FCC: 'Grow Light' Ballast causes HF interference, violates rules</h1>
<p>The ARRL has taken action over the MF and HF radio interference generated by a <strong>'Grow Light' Ballast</strong> that is used by horticulturists and can also be used for activities such as marijuana production <br>
<br>The ARRL say: <br><em>The ARRL has formally complained to the FCC, contending that a “grow light” ballast being widely marketed and sold is responsible for severe interference to the MF and HF bands. The League urged Commission action to halt sales of the Lumatek LK-1000 electronic ballast and to recall devices already on store shelves or in the hands of consumers. In a March 12 letter to the Commission’s Enforcement Bureau and its Office of Engineering and Technology, ARRL General Counsel Chris Imlay, W3KD, said the ARRL’s own laboratory testing revealed that the Lumatek device exhibited excessive conducted emissions, in violation of the FCC’s rules. <br>
<br>“ARRL has received numerous complaints from Amateur Radio operators of significant noise in the medium and high frequency bands between 1.8 MHz and 30 MHz from ‘grow lights’ and other RF lighting devices generally,” Imlay told the Commission. “The level of conducted emissions from this device is so high that, as a practical matter, one RF ballast operated in a residential environment would create preclusive interference to Amateur Radio HF communications throughout entire neighborhoods.” An extensive Conducted Emissions Test Report detailing the ARRL Lab’s test results was attached to the League’s correspondence.<br>
<br>“The Report concludes from the conducted emissions tests that the six highest emissions from the device in the HF band vastly exceed the quasi-peak limit specified in Section 18.307(c) of the Rules,” Imlay related. The ARRL further pointed out that, while a FCC sticker has been affixed to the device, it lacked FCC compliance information. FCC Part 18 rules require RF lighting devices to provide an advisory statement with the device, notifying users that it could interfere with radio equipment operating between 0.45 MHz and 30 MHz.<br>
