What's the difference between a non-dimmable LED and a dimmable LED that you'd never want to dim?
Answer: about five or six bucks.
At least, it is if you're talking about candelabra LEDs. After eighteen hours of tests, I couldn't find a single dimmable option that dimmed without flickering. The average price of those dimmable bulbs? A little over nine dollars. Each.
That makes the explicitly non-dimmable candelabra LED from Philips -- which sells in a $10 three-pack at Home Depot -- a pretty appealing option. You won't be able to dial the light down, but it does offer sufficient brightness, efficiency, and light quality. It's nothing special, but at a few bucks per bulb, it really doesn't have to be.
