Jewelry Stores Switch to LED, Save Up To 25%

October 1, 2013 By Linda Hardesty

Energy Manage jewelry storeRiddle’s Jewelry is changing halogen bulbs in its 57 locations to GE’s LED replacement lamps, saving 20 to 25 percent in annual jewelry store lighting costs.

Riddle’s Jewelry locations house between 80 and 210 spotlight fixtures, depending on store size. With the retrofit, the retailer is moving from 75-watt halogen lamps to GE’s 20-watt PAR38 LED replacement lamps.

At locations that have used GE’s LED replacement lamps for more than one year, Riddle’s has seen lighting energy cost savings between $100 and $150 a month in smaller stores (80-100 fixtures) and from $175 to $225 in larger stores (up to 210 fixtures), based on a $.10 per kWh rate and 4,000 hours of operation annually.

These savings are also the result of reduced loads on building cooling systems―each Riddle’s store typically runs its air conditioning throughout the year because of the heat generated by halogen lighting. GE’s new LED replacement lamps stay cooler than the halogen bulbs, and though Riddle’s has not yet recorded exact load reductions, store managers have reported a noticeable decrease in the cooling demand on HVAC units.

The jewelry stores also had to consider the aesthetic affect of LED lighting because lighting plays an important role in their business, highlighting precious stones. The owners say they are happy with the LED effect.
