Philips EcoBoost Lamp

  1. A few weeks ago we had a discussion about the new Philips
    EcoBoost incandescent lamp. I sent a message to Philips
    about 2 weeks ago and this morning received a response from
    the Philips press office. This seems to be public
    information, so I am posting the information here.

    Philips has confirmed the three assumptions we discussed in
    this group.

    1) The filament tube does use an IR coating.

    2) The voltage of the halogen filament is "about" 12 volts.

    3) They use a switching converter to drop the mains voltage
    to 12 volts.


    I believe12 volts is lower than the optimum voltage for the
    power rating of the EcoBoost filament. However, 12 volts is
    the voltage used for standard halogen filament tubes, and
    use of this voltage helps position the filament relative to
    the IR coating.
