I guess a test is needed. out of the hundreds I sold I never heard of it interfering on the AM band but then again not alot of people utilize AM radio. I have heard of it affecting the lower band channels on cable TV because the ballast was near a old unshielded cable running though the wall. What I have heard the most about is it interfering with Ph monitoring and test equipment. All reports of interference on Lumatek has been with in 6 ft of the ballasts.

Because of its relatively new technology. Fail rates are common with most other Electronic ballast manufactures. be Aware!! best to deal with a local supplier with a good warranty policy.
