A partnership between Xcel Energy, a utility company that provides power to South Dakota, and home improvement retailers will offer compact fluorescent light bulbs (CFLs) for as little as a dollar each. The program, announced on July 23, is designed to help residents save energy and money.

An initial public offering is in the works for Shanghai, China-based TCP International Holdings, maker of energy-efficient light bulbs.

The supplier to Home Depot and Wal-Mart Stores (among many others) makes about 3,500 kinds of compact fluorescent light bulbs, about 275 varieties of even more efficient LEDs and 12 kinds of halogen bulbs.

Acuity Brands expanded its LED indoor ambient lighting portfolio with the launch of the Z Series LED striplight by Lithonia Lighting.

The Z Series luminaires are compact, low-profile solid-state strips that deliver long maintenance-free performance in a wide range of retrofit and new construction applications, including uplight and downlight in commercial, retail, manufacturing, warehouse, cove and display. The Z Series luminaires join the portfolio of versatile Lithonia Lighting LED indoor ambient lighting products. 

Ace Hardware delivered more than 72,000 energy-efficient light bulbs to military families at the Fort Hood (Texas) Army Base, the largest active-duty military installation in the United States.

The free supply of light bulbs was intended to help residents of the Fort Hood Army Base turn their home maintenance to-do list into a to-done list as they prepare for new energy-efficient lighting standards scheduled to take effect in early 2012.

Bill Hamilton, merchandising VP electrical for the Home Depot, has a challenge on his hands. How do you explain simply and clearly the complicated changes taking place in the fast-changing category of light bulbs? 


There are already more than 100 energy-efficient bulb options on Home Depot shelves today, and a multiyear phaseout of incandescent bulbs will begin in January 2012. 


California is phasing out its incandescent light bulbs, and the first one to go will be the 100-watt variety, according to an article in the Santa Rosa Press Democrat.

The California Energy Commission said the old-fashioned bulbs wasted about 90 percent of their electricity emitting heat instead of visible light. The agency estimates California consumers will save $35.6 million in unnecessary energy costs in one year.
