I’ve experimented with a bunch of different LEDs over the last 10 years..:all EBay/China. Just ordered the newer Cobb and the round G4 disks. I do not need Tech support for a 2 wire system (polarity sensitive) or what will fit where. The ONLY LEDs that have not worked well are the strips that are not Voltage regulated...would not recommend them for replacement in your Fluorescent. I agree the panels are a better option, used them in a Fluorescent 8 years ago when the ballast went out...until then not enough savings to replace prematurely.
I have found the 5050 size chip runs the coolest and paying $14 for a $3 panel makes no sense to me. Of the 200+ LEDs I’ve bought, with the exception of strips, 3-4 have stopped working. If you want them sooner, Amazon now has them for slightly more $.
