Pretty interesting how the design of the new bulbs have become so cost-optimized. As an early adopter, I have a house full of the now-defunct Switch Lighting silicone-filled LED bulbs, which are great (but heavy). I really like the LED direction - not for any eco reasons, but for the "cool technology" factor.

Given the long life of these new LED bulbs, the I wonder when the LEDs will be engineered asa part of the light fixture and the concept of a changeable bulb becomes a thing of the past?

  Unless the bulb is industructible and there is zero possibility of breakage and bulb life is not affected by times turned on and off, and electrical surges, I'd like replaceable bulbs.
  Or are you thinking that light fixture life is going to be much shorter than it has been ;^)

    LOL! No, actually the other way around.
    
    LED bulbs should yield a much longer life than incandescent bulbs. However, one of the biggest killers of electronics is power cycling, primarily due to the thermal cycling (which yields mechanical cycling as things expand and contract with temperature), so there may be something to your "times turned on and off" concern.

      I remember a Myth Busters episode where they put several types of lights through a switching test that ran for a couple of weeks. At the end, only the LED light still worked. Don't remember all the particulars.

        Fluoro lamps- very susceptible to switching on and off so the life tests were on uninterrupted power. They give unpleasant light, they flicker, and they deteriorate over time.
