Recently there has been many improvements done for warehouse lighting. One of the major concerns was the amount of energy that the old lighting systems have been using. Luckily for everyone out there, they have the energy efficient lighting systems provided by American Lighting. In the case of Quinn CAT, they had 400 watt metal halides which were taking up a lot of energy until they had them replaced with 220 T5 highbay lights. The lighting quality itself was improved and there was a 3 month payback. Plus, additionally, the warehouse was saving $30,000 dollars a year!
