A filament bulb that is both economic and dimmable? Yes, it exists and its name is Led Bulb. A filament bulb adds extra cachet to a fixture with visible light sources. They are also a fine alternative to carbon filament bulbs, the energy guzzlers that are no longer popular due to their high consumption. Especially now that an alternative exists with the same aesthetic assets, you can once again bask in the full glory of your light. Even in a classic shape, like this Led Bulb.
