Dim the lights

Auto goes retro
Borg-Warner Automotive's Arden, N.C., plant wanted to replace the lighting in its 320,000-sq.-ft. facility. In two open office areas, outdated fluorescent T-12 lamps caused such glare on computer screens that employees were resorting to Dilbert-like measures to block the lighting. The lamps were replaced with 24-ft. suspended fixtures providing indirect lighting. With the steel Peerlite fixtures, work surface illumination went from an average of 25-ft. candles to 105-ft. candles, while glare was reduced to zero.
