What is the cost per lumen?
In terms of lumens, or units of light, prices for warm-white LED lighting packages "have declined by half, from approximately $36 to $18 per thousand lumens (kilolumens, or klm) from 2009 to 2010. Prices are expected to decline significantly, to approximately $2/klm by 2015" (DOE, www.energy.gov, accessed June 2, 2011).
These cost savings become especially significant in many business/commercial and other large-scale applications where reliability and the need to minimize replacement costs are highly important. As LC LED Corporation notes, "there is no comparison between the cost of LED lights vs. traditional incandescent options. With incandescent bulbs, the true cost of the bulb is the cost of replacement bulbs and the labor expense and time needed to replace them. . . . For office buildings and skyscrapers, maintenance costs to replace bulbs can be enormous. These issues can all be virtually eliminated with the LCD option."
