This bulb is a real eye-catcher. The radiant windings of the bulb provides a nostalgic flair comes into play especially in open, antique lamps. The purpose of this light bulb is not a good illumination of the environment. Their use underscores rather the nostalgic look of antique lamps like it would never make a standard bulb. A noble, graceful mantle of is worth its price. If the service life also still fits, I am fully satisfied.
