ActiveLED(R) Parking Lot Fixtures Achieve Energy Savings of 90 Percent in Government Facility Parking Lot Lighting Application

AUSTIN, Texas, June 7, 2011 -

- Payback with Ringdale's SSL Technology is 3.5 Years

Ringdale, Inc., a U.S.-based manufacturer of commercial solid-state
lighting (SSL) fixtures, has achieved both better
illumination and energy savings of almost 90 percent in a government facility
parking lot lighting application in Austin, Texas. Ringdale's 52W
ActiveLED(R) Parking Lot Fixtures replaced 400W and 1,000W metal halide (MH)
lights in a surface parking lot covering more than five acres.

The lighting project was completed in 2010. All of the parking lot's 97
MH lights were replaced with ActiveLED SL Series Street and Parking Lot
Lights. Compared to the parking lot's previous yearly energy consumption rate
of 265,857 kWh, the ActiveLED luminaires saved 229,241 kWh in the first year.

The ActiveLED solution provides a payback of 3.5 years. The annual saving
equates to $17,600 versus the MH lights, based on the facility's current
electricity rate.

The success of the ActiveLED installation led to more outdoor lighting
retrofit projects at the Austin facility. ActiveLED Flood Lights, Recessed
Can Lights, Walkway Bollards and Wall Packs replaced existing high wattage
lighting to illuminate the facility's buildings and landscaping.

"This ActiveLED lighting application is one of hundreds that demonstrates
ActiveLED's high performance and energy savings," said Klaus Bollmann, CEO,
Ringdale. LightSpace(R) Management Products by Ringdale provide additional
energy savings with intelligent controllers. All ActiveLED Lights come with
an industry-leading 10-year warranty on the LED device and fixture and 5-year
warranty on the power source.
