The lowly much maligned incandescent light bulb is scheduled to be phased out in the US by 2014 due to its relatively high energy consumption. Much more efficient compact florescent and LED light bubs are targeted as replacements. There's just something much more attractive and warm about the old incandescent. When placed in clear globes and used in groups they can produce a stunning effect. Image this fixture with compact florescent bulbs - yuk! Canon G11, 1/4 sec @ f/3.2, ISO 800.
