manufacturer installs LED high-bay lighting

Industrial lighting promises to be LED High Bay Lightone of the next market segments in which LED-based solid-state lighting (SSL) begins to displace legacy HID sources and fluorescent lighting. High up-front costs have limited the adoption rate of SSL in such applications. But factory owners are beginning to grasp the advantages of LEDs, and realize that sometimes having the lights off is a good thing for the bottom line.

LED lighting has certainly succeeded broadly in many applications including street lights. In the industrial space, the success has come primarily in two areas – refrigerated facilities and warehouses. Indeed the technology is regularly used in refrigerated warehouses where the fact that LEDs don’t radiate heat is a good thing LED High Bay Lights IP65for the refrigeration system. And the warehouse angle is important because workers are only sporadically present in specific areas of a warehouse, so such installations can take full advantage of the dimming capabilities of LEDs based on occupancy sensors or networked controls. In fact, network lighting system specialist Digital Lumens has reported customers achieving 90% energy savings in cold-warehouse applications. The case for LEDs isn’t quite so clear in the broader segment of industrial applications. In factories with workers spread around a manufacturing floor, there is often less of a chance to leverage dimming, because the workers need the lights. Moreover, some business owners simply have a mindset of wanting the lights on. Customers visiting a well-lit factory may perceive the lights positively thinking the factory is busy, and may perceive darkened areas negatively. Industrial and manufacturing

The company doesn’t have an exact measure of the aggregate savings attributable to the lights, because the lighting is on the same power meter with office lighting, the office heating ventilation, and air conditioning (HVAC) system, and office ETL T5 LED Tube equipment. But comparing the month of August from 2011 with the month of August from 2012, Paulk said electricity usage was down 39%. Clearly the specific percentage of savings strictly relative to plant lighting is greater.
