My personal issue with the CFL's is the color rendering, they have come a ways but I still can't tell which socks are blue and which are black unless I open the shades and hold them up to the natural light. Congress would be smart to push the bill until LED's come further and down in price. You would then never really need to replace the lamp (unless you use it more then 100,000 hours.
We use LED for commerical lighting, but the ROI (return on investment) is not there in Wisconsin, where electrical energy is around $.85/KWH for commercial purchase. NY and CA it is a bit different where energy can cost upwards of $.16/KWH, so the payback drops/ROI drops below 8 years as a replacement for Metal Halide or Incandecent.
