    Question regarding Phinney-Walker/Semca Corp. roll/flip alarm clock

    Hi folks. Recently purchased this vintage alarm clock. Everything is working fine. My only gripe is that the bulb is not bright enough to view the time in a dark room. Before I venture into disassembling the clock, is this normal for this era? Do the bulbs get dimmer with time, or do they simply "burn out" completely. I even considered maybe using some aluminum foil near the existing bulb to diffuse the light. One last question... must you replace the original bulb with an exact duplicate, or are there modern, compatible bulbs available that are brighter?

    Thanks,

    Craig C.

    Hi Craig,

    I don't know, but I would expect an alarm clock from that era to have
    neon lamp illumination. If you are going to sleep near it most would
    not want an alarm clock to be too bright at night. So, the illumination
    would start out dim. Neon lamps do lose brightness as they age, but
    they would be considered non-replaceable.

    Even if the lamps are not neon, if you are going to replace the lamps
    you would you need some knowledge of electricity and it may require
    some soldering. Neon lamps are still available, but may not be exact
    replacements. These days LED lamps would be used in that application.
    However, replacement with LEDs would require doing some arithmetic
    and soldering. LED lamps may have a lifetime similar to the neon lamps.


    Thanks,

    I wonder if 2 bulbs were used and one burned out. The flip clocks I remember were very readable at night. If it is something like an ne2 they are sold with the required resistor connected.
