Turns out, changing a light bulb is harder than
it seems.
New bulbs using halogen, compact-fluorescent
and LED technologies have been sprouting up on store shelves recently. The
flurry of products is a result of legislation passed in 2007 that requires
general-purpose bulbs, starting in January, to be at least 25% more efficient
than those using standard incandescent technology invented by Thomas Edison in
1879.
As a result, most of today's incandescent bulbs
will be phased out (some specialty bulbs are exempt) by 2014 and replaced by
more efficient alternatives. While cheap at 25 to 50 cents a pop, incandescent
bulbs waste nearly all their energy in heat output.
The light-bulb industry now faces a daunting
task of re-educating shoppers who are still in the dark about their choices. A
recent survey by General Electric Co. shows three-quarters of consumers have no
idea about the new regulation and impending changes.

"They have all these new types of lights,
and it's difficult to ascertain the benefits," says Don Hough, a New York
City resident who frequently shops for bulbs for his residence and medical
education and marketing business. "And the people working in the store,
sometimes they don't know either."
Most people are accustomed to buying bulbs
based on watts, which refers to energy usage. Soon, they'll buy based on actual
brightness, which is measured in something called lumens. That's because
manufacturers have figured out a way to produce the same amount of light with
fewer watts. For example, a typical halogen-incandescent model today needs only
43 watts to create 800 lumens--the same brightness as a 60-watt incandescent
bulb.
"You talk about lumens and the consumer
looks at you like you're speaking French to them," says Bill Hamilton,
Home Depot Inc.'s electrical merchandising vice president who says stores have
seen worried consumers hoarding incandescent bulbs.
To help translate, manufacturer GE this fall
will introduce a dramatic packaging overhaul, organizing its light bulbs by
lumen level using five different colors--yellow, green, blue, orange and
purple. A watt-conversion will be on the package. Other brands, such as Osram
Sylvania, will color-code packaging based on the light's actual color (warm and
cool). By next year, the Federal Trade Commission will require manufacturers to
post "Light Facts" labels on most bulb packaging with info about
brightness, light appearance and annual energy cost, among other things.

"It's a very significant shift for
us," says Kristin Gibbs, GE's general manager of consumer marketing for
lighting. "We've got to manage consumer anxiety through this."
Initially, consumers will find three main
alternatives to incandescent bulbs on shelves: halogen-incandescent, compact
fluorescent (CFL) and light-emitting diodes (LED). Many are designed similarly
to the familiar pear-shaped "A-Line" bulb consumers know. Halogens
behave most like existing bulbs, but have an inner capsule filled with halogen
gas around a filament to make the bulb about 25% more efficient than a
traditional incandescent. They're also the cheapest alternative at less than $2
each.
"It's essentially a souped-up incandescent
bulb," says Peter Soares, director of marketing for consumer lighting at
Philips Electronics North America.
CFLs, by comparison, produce a 75% energy
savings and cost about $2 to $5 each. However, the bulbs contain faint traces
of mercury, which can be released as vapor if the bulb is broken until properly
cleaned up, according to the Environmental Protection Agency.
The tell-tale "spiral" shape many
consumers find unsightly is now often hidden inside a pear-shaped outer bulb.
And consumers who complained about the bulbs' blue, sickly hues are finding new
CFLs that produce light that is equally warm as incandescent, says Mr. Soares
of Philips. "In the end, CFLs may be a bridge technology to get us to some
point in the future."

That future, most in the industry believe, is
the LED lamp--an ultra-compact light source using a semiconductor chip that is
up to 85% more efficient than incandescent and lasts 25 times longer.
LEDs remain the priciest option, with 9-watt
and 13-watt bulbs that replace 40-watt and 60-watt incandescent models costing
from $20 to $55 each. Despite the price, they're gaining traction, and bulb
costs are expected to drop dramatically over the next three years. Sales of
LEDs at Home Depot, including the retailer's own "EcoSmart" bulb
brand, rose 500% in the last fiscal year ended Jan. 30. "I really believe
LEDs will be our light source for every socket in our home in very short order
here," says the retailer's Mr. Hamilton.
In coming months, Philips, Home Depot, Osram
Sylvania and other major brands will roll out LED substitutes for the 75-watt
incandescent bulb, and a spate of 100-watt-equivalent LEDs are expected next
year. One start-up, San Jose, Calif.-based Switch Bulb Co., says this fall it
will offer an LED substitute for the 100-watter with suggested retail price of
about $30.
The U.S. Department of Energy estimates that
bulbs compliant with the new law could save U.S. households nearly $6 billion
in energy costs in 2015, when rollout is complete. Consumers may also be able
to put brighter bulbs in their existing lamps and fixtures because the new
bulbs use less wattage.
"Right now people don't think about light
bulbs," says Ellen Sizemore, product marketing manager for LED retrofit
lamps at Osram Sylvania. "And the industry is going to force them to do
that."
