NEW YORK, November 17, 2009 — Research shows that office environments that team task lighting with reduced ambient lighting levels provide better comfort for workers while lowering energy costs. Humanscale’s complete line of ergonomic task lighting is designed to provide optimal illumination via state-of-the-art technology while maximizing the cost savings of dual-source lighting schemes.

According to human factors research at the Cornell University Department of Design and Environmental Analysis, eyestrain is the top health-related complaint among office workers, resulting in some 79% of computer users wanting better lighting. Research by Brusking/Goldring shows up to 80% of office workers experience at least one negative effect from poor lighting and 75% want more lighting control.

Task lighting provides ergonomic comfort by supplying the right amount of adjustable illumination while reducing glare and the risks of computer vision syndrome—a condition causing eyestrain, eye fatigue, dry eyes, light sensitivity, blurred vision, headaches and other symptoms. Task lighting has also been shown to elevate mood and positively influence productivity, according to research by Cornell University, the Light Right Consortium, and other sources. What’s more, studies published in Applied Ergonomics found that controllable task lighting can lead to as much as a 4.5% increase in productivity.

According to research, lighting accounts for nearly half the energy used in commercial buildings. By implementing task lighting at each workstation in an office, ambient lighting levels can generally be reduced. And when lower levels of overhead lighting are combined with task lights utilizing high-performance LEDs or compact fluorescent bulbs, the energy savings can be significant. In fact, studies have shown that a dual-source lighting scheme can reduce energy from lighting by as much as 67% while still providing comfortable lighting levels. That profound energy savings can reduce a building’s overall energy consumption by as much as 25%. Less energy for lighting means lower operating costs—not to mention less pollution.

Among Humanscale’s lighting offerings are the award-winning and ultra-efficient Element LED and Tolomeo LED task lights. Consuming just seven and 10 watts of power, respectively, both produce light output equivalent to standard incandescent task lights. Humanscale’s line of Diffrient task lights is also designed for energy efficiency, as the Diffrient Work Light II, Diffrient Task Light II, and Diffrient Technology Light all accommodate the latest compact fluorescent bulbs.
