Is voltage important replacing halogen bulb?

    Hi,

    My wife has a halogen desk lamp with SBE e101956 stamped on it. That's the
    only indication of make or model. It takes one J type bulb, up to 100W, and
    states 120 volt. It also has a dim & a bright setting.

    The new bulb I bought is 130 volts, type J, and it fits and works.

    Questions:
    - does using 130 v, rather than 120, matter?

    - the new bulb states, "Use in systems that do NOT feature a voltage
    transformer connected directly to the main volt supply. (110/120V)."
    I don't understand what this means, and don't know how to determine if the
    lamp has such a transformer.
    How can I tell about the transformer? Does having a two-setting switch
    indicate a transformer? I measured the voltage (without a bulb) at the
    contacts, and it doesn't change when the switch is moved. I think it was
    around 109v.

    Any help is appreciated.

    Thanks,
    Dugie
