Sounds like a great review! Regarding the specific rather than the meta: I'm very satisfied with the "filament LED" candelabra bulbs from Amazon. I've bought several brands, usually whatever is cheapest. I'm even using e12 to e26 adapters in some fixtures so I can standardize on them. There are lots of comparables on Ebay: https://www.ebay.com/sch/i.html?_nkw=e12+filament+led https://www.ebay.com/sch/i.html?_nkw=e12+filament+led. I don't know the actual spectrum, but I like the light quality, and haven't had problems with durability. If you haven't tried this style yet, you should. It's a good design, since it works directly off mains voltage and thus avoids the quick-to-fail heat-sensitive capacitors used in standard LED bulbs: https://en.wikipedia.org/wiki/LED_filament https://en.wikipedia.org/wiki/LED_filament
