I for one am glad incandescents are disappearing. LEDs are cheaper in the long run. I have no need to keep a light on my batteries.

Cheaper?
At what cost?
Sure, perhaps they do make a bit more light and less heat but in reality they cost more to manufacture and use TONS of highly toxic materials to make them.
Just a small list of some of the materials used in making LEDs..
"A semiconductor is a crystalline material that conducts electricity only when there is a high density of impurities in it. The slice, or wafer, of semiconductor is a single uniform crystal, and the impurities are introduced later during the manufacturing process. Think of the wafer as a cake that is mixed and baked in a prescribed manner, and impurities as nuts suspended in the cake. The particular semiconductors used for LED manufacture are gallium arsenide (GaAs), gallium phosphide (GaP), or gallium arsenide phosphide (GaAsP). The different semiconductor materials (called substrates) and different impurities result in different colors of light from the LED.
Impurities, the nuts in the cake, are introduced later in the manufacturing process; unlike imperfections, they are introduced deliberately to make the LED function correctly. This process is called doping. The impurities commonly added are zinc or nitrogen, but silicon, germanium, and tellurium have also been used. As mentioned previously, they will cause the semiconductor to conduct electricity and will make the LED function as an electronic device. It is through the impurities that a layer with an excess or a deficit of electrons can be created."

HEREThe processing uses considerable amount of energy (electricity) to make semiconductors, creates bunches of hazardous materials in gasses and solids that need proper handling and disposal..
Even then when the LEDs fail, you WILL end up putting all those dead LED bulbs in normal trash so now we get to pollute landfills even more with "E-waste".
Waste a lot of energy and raw materials and create tons of hazardous materials to create a product that costs more to buy all in the hopes to save a couple of pennies of electricity and a few ounces of CO at a remote power plant.. :S :h
I am not against LEDs, but being FORCED to buy something on the pretense that it is "better for the environment" when in the bigger pix it is not any better when you look at the overall process.
But NO ONE wants to talk or listen about the side effects and pitfalls around here.
Put you fingers in your ears and repeat loudly "LA LA LA LA LA LA LA"
