    I prefer LED myself, so I hope they will take over first place!

    I hope that, during my lifetime, there will be a liberal president.

      After reading other comments I consulted with teh Google to see if things have changed. LED's have surpassed CFL bulbs, but cost a lot more.

      So CFL's are more cost effective, but use a bit more power than LED.

      FYI

      •  LED lamps last (almost) forever (5+ / 0-)

        something like 50,000 hours (5 plus years).  That's huge savings in the long run.

        There are very few subjects which do not interest or fascinate me.

        •  Looking this up, I found 25,000 - 50,000 hours (3+ / 0-)

          is the expected LED lifespan, with CFL's rated at 8,000 hours. (LED bulbs tend to dim over time, instead of burning out, so lifespan is somewhat vague.)

          If the life is closer to 25,000 then the cost is comparable with CFL's. If they reach 50,000 then the cost for LED is about half of CFL.

          But that also requires a long-term invest LED, which reduces he value with respect to cheaper CFL. (My CFL bulbs are over 5 years old, so an equivalent LED would need to justify a 10+ year investment.)

          I'm a big fan of LED, and expect them to lead the market at some point, but the trade off isn't "huge" quite yet. At least in my mind.

          I hope that, during my lifetime, there will be a liberal president.

            ceiling fixture that uses the bayonet style small flood.  I had been using 25 w halogen in them (from the previous owner had 45 w).  The IKEA 3 w LED fit and are much cooler and just as bright as the 25 w halogen.

            I am trying them out to see how the work heat vs light (lumens)..
