I usually order form Amazon for convenience, but sometimes use shopping.google.com. I look up every site before ordering though. Some of the sites that show up in the results are sketchy or deceptive. I also sometimes use Ebay if I’m ok with buying something used, or something very cheap of questionable quality (from people who I’m guessing are just resellers of Alibaba crap).

I haven’t had a filament LED fail on me yet. The cheapest LEDs you can find aren’t worth it; best to get a name brand.

Plants don’t need much, if any, green light (they reflect it). LEDs can be made to be full spectrum. I can think of no reason why anyone would want incandescent lights for plants. Even before cheap high power LEDs were a thing, people usually used high pressure sodium lights.
