Rated 4 out of 5 by GeorgeTW satisfactory product at a bargain price
the glass tube is not high quality, there are bubbles and impurities trapped in the glass but the bulb has been working for two months now and they do not seem to affect it's operation.

Rated 5 out of 5 by ClosetCollectables Used to Purple Glass
We use these lights in a purpling box to turn old clear glassware purple. Before a certain date, manganese was used as a clearing agent. With sunlight or UV rays it will turn purple. These work very well for the process although it is not what they were originally intended for.
