Carbon filament bulbs and filament lighting add a unique effect to any room. These Edison style light bulbs bring an old-time feel to any space. Carbon filament light bulbs were predominantly used in the 20th century. Today filament lighting isnít used quite as much due to their shorter life, but is still used for decorative or ambiance settings. At BulbTown, we offer discounts on our carbon filament light bulbs and even have novelty versions, such as the Balafire Flicker.
