(OEO: Lake Zurich, IL) -- When home-demonstration merchandiser Princess House wanted to improve lighting and decrease energy usage in its 200,000 sq ft warehouse, it turned to OEO Energy Solutions. The solution was to replace the existing 278 360W metal halides with 278 OEO EZ LED 230s. LED lighting is more energy efficient than other lighting, including compact fluorescent lamps (CFLs). And unlike CFLs, there are no recycling concerns. Using OEO’s simple plug-and-play LED lighting, Princess House now saves 43 percent on their electric bills.

 The challenge

• Huge energy bills
• Low light levels of 18 foot-candles (FC) with new metal halides, and as low as 9 FC with old (spaced 25 ft high and 25 ft apart)
• 15- to 20-minute delay time for startup and re-strike
• Uneven, inconsistent light quality throughout plant
• High heat temperatures from metal halides
