Modern warehouses typically cover hundreds of thousands of square feet with operations that rely on logistics that can be timed down to the second. The efficiency and profitability of warehouses can be vastly improved with lighting that gives employees the best visual acuity at all levels in a warehouse, including between shelves and down long aisles. LED lighting systems, like those produced by Cray LED, are ideal solutions to provide these lighting conditions.
Warehouse architects and engineers aim for performance, visibility, beam uniformity, and optimum color rendering indices when they design lighting for modern warehouses or to retrofit existing facilities. LED lighting improves performance through efficiency and lower maintenance costs that cannot be achieved with traditional metal halide luminaires. LED systems use twenty to fifty per cent less energy to deliver the same or even better illumination. LED fixtures last, on average for over 100,000 hours of continuous use, which substantially reduces replacement costs over the life of the luminaires.
LED lighting provides unparalleled visibility throughout any size or configuration of a warehouse, including facilities with large open spaces and those with multiple storage racks. LED’s have naturally higher luminance ratings, which makes it easier for warehouse workers to see fine detail and to distinguish between similar crates or parts. Improved visibility also contributes to employee safety by reducing accidents that can be caused by poor lighting.
Elements of Efficient Warehouse Lighting
Beam uniformity is on often under-appreciated aspect of warehouse lighting. Warehouse workers experience lower levels of fatigue and eye strain when they work in areas with more uniform light conditions. Occupational analysts have long recognized the eye strain that can result from frequent transitions between light and dark areas of a workspace. LED lighting can be configured to provide the same levels of lighting throughout a warehouse, both in open spaces and among racks. Over the course of a standard workday and employee will be better able to maintain optimum performance levels in spaces that are more uniformly illuminated.
The Color Rendering Index, or “CRI”, of a lighting system is a measure of how well artificial lights can match natural lighting conditions. Under ideal natural light, color variations and contrast are more readily recognized. Cary LED’s lighting systems can be optimized to provide the best CRI index for a specific warehouse facility. Moreover, unlike traditional metal halide systems, LED systems require no warmups. A power surge or other interruption in electrical supply can cause a lengthy stop to warehouse operations that are lit with traditional fixtures. With LED systems, lights will come back on at the best CRI and with ideal uniformity virtually immediately after power is restored.
Warehouse retrofitters will sometimes make the mistake of just adding more traditional fixtures when seeking to improve warehouse lighting. Adding more fixtures adds only marginal lighting improvements with little, if any, improvement to overall warehouse operations. Retrofitting to a modern LED system will require a greater initial capital outlay, but that outlay will be recovered in a very short amount of time through reduced energy and maintenance costs, and with better employee performance.
