I just install a 48' string of the Feit brand lights. These use the E26 bulbs and I spent a lot of time reading reviews of string lights before choosing the Feit lights. The reviews I found were very favorable and after getting the string and looking it over it was obvious that it was a well made high quality product. Obviously I can't personally vouch for the longevity of the bulbs yet, but each of the bulbs lit up the first time I turned the string on. This is the string I bought, Feit
710090.
I didn't have an outlet anywhere close to where I wanted to run these lights, so I replaced the door light fixture o the deck with this
one, which provided two GFI protected outlets. I used a plug in Alexa compatible Wi-Fi dimmer adapter so I could control them easier. That light fixture allows adjustments of how it's bulb turns on and off, so I just leave the light switch in the on position all the time.
Here is the bulb only location on Amazon
Damn, you asked a really simple question and I respond with an avalanche of data, sorry.
