While living in the hills above Santa Rosa CA, a 6-month-old CFL I'd put in the unheated laundry room expired noisily. Although some distance from my antennas, it produced s9+ noise from 160m - 10m.

Hi Mike. NOT being an attorney, I can't be blamed when someone spends $15,000 trying to win such a case -- and can't! However, it is common sense, IMO. FWIW, one might try Small Claims Court, where,
