FINDING: On a life-cycle basis, warm and cool white LEDs are already cheaper than incandescent lighting and will likely be comparable to that of fluorescent lighting technologies in the near future. For applications where the daily usage is larger than 10 h/d, cool white LEDs have now a similar consumer cost to CFLs or T12.

ROLE OF GOVERNMENT IN AIDING WIDESPREAD ADOPTION
