the fixture that best solved its exacting formula for lumen output

Johnny Janosik conducted a seven-month evaluation of several competitive LED offerings beginning in early 2011. The home furnishings seller sought the fixture that best solved its exacting formula for lumen output (the total amount of led high bay light emitted by a source) and foot-candle intensity (the amount of light that actually falls on a given surface).

"Our ceilings vary from 12 to 14 feet high so we needed the light to deliver a powerful punch without being too bright that it washed everything out," added Koehler.

In October, GE's energy smart? 12-watt led linear high bay light was selected to replace the store's 4,000 75-watt halogen spotlights. Although the LED lamps produce approximately 30 percent fewer lumens than comparable incandescent and halogen options, advanced optics concentrate light on the target, diminishing wasted extraneous light.

Before the swap there was a lot of ambient light that tended to give our showroom a bright 'big box' appearance," Koehler noted. "Now that the LEDs are focused down on the floor, there's very little light noise above the displays, which really makes them 'pop' without adding all that extra illumination throughout the store."
