Fan blade LED lights.
I needed something brighter for my parents garage and I didn't want to have to bring someone in to rewire the lights. I found an interesting product for $30 on Amazon which was a 3 blade LED light that fit in the socket and it seemed interesting enough to try. Literally night and day for the fan blade side vs incandescent bulb side.
Being cheap, I looked up purchasing them in direct from China. $14 including shipping upgrade for the 3 blade and $18 for a 4 blade. Showed up in 2 weeks in wimpy packaging, but nothing was damaged.
I just wanted to be able to see things in the dark garage at night. Now the garage feels like a show room. For $45, that's totally worth it.
This is the one I got:
