There's a place called Light Bulb Depot up on South Blvd. in Charlotte,
https://www.lightbulbdepot.com/ I have dealt with them before for some hard to find bulbs for my insulator lamps and they are very good. They have a walk-up counter and will bring out different bulbs for you to try out.
The big thing with the new LED bulbs is to watch out for the lumen rating on them, the bulbs that Creighton linked to are only 12 Lumens, so they are going to be fairly dim. A 15W candleabra base night-light bulb is around 20 lumens, which is still very dim. That's why the ability to test them out is nice, get a good feel for what you need.
