Lighting Roundup: Lumiette, Cree; Firms Fail to Recycle CFLs

Here’s a roundup of the latest news in energy-efficient lighting.

Only a third of businesses and just two percent of individuals recycle their compact fluorescent (CFL) bulbs, according to the Association of Lighting and Mercury Recyclers. Sustainable Business reports that as a result, CFLs are contributing to the release of roughly four tons of mercury a year, about a tenth of the mercury output of coal fired power plants.

Companies offering in-store CFL recycling include Home Depot, Lowes, Ace Hardware and Ikea, and other recycling locations can be found at LampRecycle.org.

Lumiette has launched a flat panel lamp (FPL), the Xcellume PAR 38 (pictured). This has the same lumen output and other performance metrics as an LED lamp, but costs the same as a dimming CFL, consuming only 15 watts to produce 750 lumens, Lumiette said.

The FPL also offers the flood lighting and warm color characteristics of incandescent, the company said. It added that the bulb reduces power consumption (versus an incandescent equivalent) by 75 percent, saving more than $112 with a useful life of 25,000 hours.

Cree has introducing a lighting-class LED array, the Cree XLamp CXA2011, which is designed to deliver the smooth light output and consistent color needed for applications such as omnidirectional bulbs or directional downlights. The company says the array delivers up to 4000 lumens at an operating temperature of 85 C, and allows customers to create a broad range of LED-based designs with lower system cost.

Intematix has announced new additions to its ChromaLit collection of remote phosphor light sources, which are designed to optimize light quality and efficacy for applications including down, spot, under-cabinet, linear, task, area, ceiling panel and industrial lighting.

Available shapes now include round, square, linear and panel, and Intematix is offering a variety of color temperatures and color rendering indexes (CRI). The entire ChromaLit family is now available through Future Lighting Solutions.

  1. Regarding the release of mercury into the environment due to CFLs not being recycled, the figure quoted of 4 tons per year is incorrect.

    First, that figure was calculated assuming a figure of 5 milligrams of mercury per CFL. But that assumption is no longer true. It may have been the case in the past, but more recently manufacturers have reduced that by half or more.

    Furthermore, whatever amount of mercury starts out in the CFL, most of it becomes chemically bound to the coating on the inside of the glass as the bulb is used. By the time the bulb burns out, only about 11% of the mercury remains free to disperse into the environment if the bulb is broken (EPA website information).

    A better estimate of the amount of mercury released by non-recycled CFLs is therefore closer to 0.2 tons per year. That is perhaps 0.2 percent of US mercury emissions annually, most of which is due to the burning of coal.

  2. Also, the annual US release of mercury, mostly due to the burning of coal, is over 100 metric tons (EPA website again). Not 40 tons, as one might conclude from the article.
