Lighting is a major sources of electricity consumption. Incandescent bulbs are known to be very energy in-efficient because they waste a lot of energy in the form of heat. This year has seen a big push for more efficient lighting solutions. Several countries around the world have banned the use of traditional incandescent bulbs including, Australia, Canada and Brazil. In the US, President Bush’s recent energy bill stated that beginning 2012, all new light bulbs will have to use 25%-30% less energy for the same amount of light as today’s bulbs.
There are many energy efficient alternatives to incandescent bulbs, including LEDs and halogens, but so far compact fluorescent bulbs have received the most attention and adoption. Compact fluorescent are currently up to 70% more efficient than incandescent bulbs and last 6-10 times as long, reducing both energy usage and waste. Wal-Mart has been one of the main supporters of compact florescent bulbs, pushing the bulb's sale within their stores.
The main complaint about compact fluorescent bulbs so far, has been the institutional, harsh, cool light that they give off. North Americans in particular, prefer the warm light of an incandescent bulb in their homes. The warm light is gives emotional comfort and a perceived sense of calm.
“To many people, giving up incandescent lighting means relinquishing some intangible, beloved quality associated with home in favor of a ghastly institutional glow.”
The New York Times recently published
this article about compact fluorescents. They asked 12 members of their staff to try out 21 different low energy light bulbs (including 14 compact fluorescents) and evaluate them based on the quality of light. Their top choices are summarized in
this chart. Their first choice was the Phillips Halogena because it produced “nice, soft, golden light”. The top compact fluorescent choices included the n:vision TCP Home Soft White and the TCP Spring Light/Soft White.

“Although most of the compact fluorescents were deemed unacceptable by the panel, there were several that were found to be not only acceptable but attractive.”
Although adoption of energy efficient light bulbs has been slow, the attention to these bulbs is still new and the technology and education systems around these alternatives is still developing. Tom Dixon is quoted in the article in regards to the quality of light produced by compact fluorescent bulbs, saying “I’m sure there were the same arguments when gas lighting replaced candles. The light’s quality is very different, and it’s going to take people some time to adjust to that.”
