Arizona Envelope Company, a 30 year old manufacturer and printer of envelopes of all sizes and shapes, contacted Relumination to upgrade the lighting in their production areas. Light levels were fine during the day, thanks to sky-lighting, but at night they were very low. As a 24/7 operation it is important to maintain light levels day and night. Workers were happy with the new light levels and management was happy with the energy and maintenance savings. After the production areas were completed and savings was verified, AZ Envelope decided to do the rest of the facility, including warehouse areas, offices and the exterior lighting.
