Halogen Replacements for Standard (Edison base) bulb

    I need a fully dimmable light for a kitchen fixture. I like the light
    quality and the relative to incandescent energy savings of the Phillips
    Eco Advantage bulbs. I'm not thinking well of the lifespan though. You
    wouldn't want to work in a work lamp as it can't take a knock. And my
    kitchen light, which is generally partially dimmed has burnt out after a
    few months.

    I'd like to try another halogen. Others seem to be rated at 1500
    hours (like GE Reveal), but I've heard the GE can be noisy when dimmed.

    Any experience or suggestions?

    I've given up on the idea of dimmable CFLs, too many quirks with the
    rated for dimmable bulbs. And not good life. I do need an even spherical
    light (fixture is pendant IKEA), which cuts out the directional LED
    types. Not that I know much about their dimming characteristics.

    Do halogens have problems with dimming? I thought the interior of the bulb gets
    a black coating when dimmed.

    You didn't say what size lamp you are looking for. Home Depot sells a
    $10.00 dimable LED bulb that might fit your needs. Very even light.
    "40-watt" size takes 8.6 watts.

    I use one of these in a reading lamp with good results. I now have 2
    LED lamps in my house, and am happy with both.

    Thanks.

    It appears that I shouldn't dim this too low, and that either iodine
    or bromine fields better low temperature results.

    With a reduced voltage the evaporation is lower and there may be too
    much halogen, which can lead to abnormal failure. At much lower
    voltages, the bulb temperature may be too low to support the halogen
    cycle, but by this time the evaporation rate is too low for the bulb to
    blacken significantly. There are many situations where halogen lamps are
    dimmed successfully. However, lamp life may not be extended as much as
    predicted. The life span on dimming depends on lamp construction, the
    halogen additive used and whether dimming is normally expected for this
    type.

    And:

    Halogen bulbs used on a dimmer will last longer if they are set to full
    "ON" for two minutes before being turned off — this helps the particles
    from the filament complete their cycle.
