Metal Halide to Fluorescent to LED. Bay Logistics warehouses and ships products for EarthTronics, a Michigan-based, energy-efficient lighting solutions company. EarthTronics LED bulbs, linear LEDs and LED fixtures are sold under the EarthBulb brand name to commercial and industrial facilities, hotels, restaurants, retail stores and residential homes. All EarthBulb lamps provide more than 80 percent energy savings. At its Spring Lake facility, Bay Logistics replaced its antiquated metal halide fixtures with six-lamp, high-bay, T8 fluorescent fixtures to illuminate its rectangle, 200,000 square-foot metal fabricated warehouse. EarthTronics recommended the company invest again in its high-energy-efficient, smooth-dimming, 15-watt T8 LED linear tube that delivers 146 lumens per watt, producing 2200 lumens. It features glass-tube construction that ensures proper cooling to support high lumen maintenance for a 50,000-hour rated life. The new T8 LED is engineered to work with popular dimming systems found in many meeting and conference rooms, as well as in energy-saving, daylight-harvesting applications. It was an excellent fit.
