Nothing terribly new here, but was trying to understand the timeline of incandescent phaseouts

"China to phase out incandescent lightbulbs - Nov 5

The lights are going out for incandescent bulbs, as China pledges to replace the 1 billion it uses annually with more energy efficient models within five years.

Beijing's move is a major step in efforts to improve lighting efficiency and reduce greenhouse gas emissions. Lighting accounts for 19% of electricity use worldwide, according to a 2007 estimate from the International Energy Agency, a figure that could drop to 7% if the rest of the world followed China's lead, the Global Environment Facility fund said."

The following is a great summary of actions around the world to eliminate incandescent lighting.

http://en.wikipedia.org/wiki/Phase-out_of_incandescent_light_bulbs

-"By October 2016, all incandescent lightbulbs will be banned in China. "
-"[In the US] the federal government enacted the Energy Independence and Security Act of 2007, which requires all general-purpose light bulbs...be 30% more energy efficient (similar to current halogen lamps) than then-current incandescent bulbs by 2012 to 2014...By 2020, a second tier of restrictions would become effective..."
-Many other forward looking countries already banning incandescents.

Given the various phase ins, it looks like the next 5 years will be the sweet spot in terms of the demand for the REEs used in lighting.
