I again must agree with you Dave...  Using the word "Federal" with a
grow light owner almost always gets action...

Chinese generic things... one is still in use and perfectly quiet even with a sw rx with ferrite rod antenna right next to it... the other one got sent to the arrl lab for dissection as it radiated all over the place, so I lost a few bucks, but maybe the arrl got some experience with bad bulbs.
