The European Union enacted its ban today on incandescent light bulbs, allowing shops to sell their current supply but not buy or import more of them.
The switch to compact fluorescent light bulbs and LEDs is expected to reduce the electricity used for lighting and help the region reduce its greenhouse-gas emissions, but the move is prompting vocal opposition from artists, parents, health advocates and even environmentalists.
The United States should take note, as its phasing-out of incandescents begins in 2012 (see Vu1 raises $5M for lighting tech).
The EU ban follows similar legislation in Australia and Cuba (see European Union to phase out incandescent light bulbs).
Part of the criticism of the lighting mandate comes from artists that use incandescents to emphasize colors, or to light existing sculptures or art installations.
"Most of these lights have been designed specifically for the art work. I cannot find a suitable energy-saving lamp to fit those requirements," Peter Orth of the Orth House Museum told Deutsche World. "Changing the system would mean major structural changes, including tearing down walls, which again requires so much expenditure. Then where's the energy savings?"
The report noted that "incandescent light bulbs bring out the entire spectrum of light, [while] the energy-saving lamps have higher components of blue and white, which can make the light appear more artificial."
The New York Times found a variety of other complaints, including parents upset that traditional fairground lights must be replaced, health advocates who say energy-saving lights can be harmful to epileptics, and environmentalists concerned that small levels of mercury in compact fluorescents could have immense impact when the bulbs become more popular. EU officials have said they want to force compact fluorescent light bulb makers to reduce the mercury content from 5 milligrams per bulb to 2 milligrams.
In the meantime, there are multiple reports of people stockpiling incandescent light bulbs. Consumer research organization GfK told the New York Times that sales of incandescent bulbs in Germany were up 34 percent during the first half of 2009.

Life Cycle Analysis of LED vs incandescents
Submitted on September 5th, 2009 by Unregistered user (not verified)I have never seen a full analysis of the cost of making - and disposing - of LED lights vs. incandescent lights. True - LEDs do use less energy when they are in use, and they do last longer. But how much energy and materials are used in their production - is it more than incandescents (yes - but by how much, 10% ?, 10x?)
Unless a full life cycle analysis is performed, then the savings may be an illusion. I have never seen such an analysis.
There is a precedent - we replaced incandescent street lights with sodium vapor lights over the past few decades (which is my the night sky is orange now). Has this resulted in any cost-savings to municipalities?
Carnegie Mellon University Cradle to Grave SSL Study
Submitted on September 29th, 2009 by Nik Nicolakis (not verified)To your point, CMU is actually actively performing this very study. It is a great point, as many of the SSL manufacturers currently use manufacturing intensive methods for extrusions and finished fixtures that are used as part of the over-all thermal management of their designs.
That is why many SSL products and luminaires have alot of aluminum and metal.
In many cases this process alone will allow you to burn far more incandescant lamps with less of an environmental impact than the energy efficient SSL counterparts.
That said, there are few SSL luminaire manufacturers that were aware of this issue arrising and set out to design around it with success. LEDs on the chip level are also becoming more robust as efficay rises, which allows manufacturers to design with less heatsinking, therefore less intensive manufacturing processes. A simple search will net you results on the CMU study.
