    Comments about Bulbrite 100 Watt, 120 Volt A21 Half Silver Bulb:

    The service from the company was good. In my opinion, the price of the bulbs are expensive.
    The lighting from the bulbs seemed sufficient but the actual life of the bulbs are shocking.
    I purchased three bulbs and simultaneously put each of them into my hanging lamp. One of the bulbs burned out in less than I month!
    I will never purchase these again.

      Comments about Bulbrite 100 Watt, 120 Volt A21 Half Silver Bulb:

      We placed this in a chandelier where the bulb is very visible. We had a clear bulb in place, which looked cool when the light was off, but when on was far to bright to look at, even when dimmed. The half silver bulb allows us to get ample light, but screens the light from the lower half. Plus it looks cool when turned off.

        This would be used over a kitchen island where people sit. Can I get them without the writing on the tip of the bulb ?

          A:

          Although our most recent photo does show writing on the bulb, Bulbrite no longer includes the writing on the A21 Half Silver Bulb.
