I bought some FEIT 4' shop lights for the garage. They work well but are
noisy in BCB and lower HF. My antennas are right above the roof. Because
I turn off the shop lights when I'm not in the garage they don't present a
problem with hamming or the kitchen AM radio that is at the opposite end of
the house. Otherwise, I would have to do something about it such as
explore filters.
While some brands seem better than others, in general I have found that you
can't simply count on a brand. You have to buy the lamp and test it.
