I have had good luck with several products here; https://www.1000bulbs.com/product/204208/CMS-C9SWW.html https://www.1000bulbs.com/product/204208/CMS-C9SWW.html They have an array of temperatures and has an old look. I bought 1000' feet of their spool and bulbs and have been using for about 7 years with zero issues. Only bulb to go out was because I dropped it on some concrete. I also did this after a couple years of what turned out to be single use lights from big box store. It's not cheap but not sure what your budget is. At least you can get some mileage out of them.
