ActiveLED® High Bay Round Light Delivers Performance and Durability

Unlike conventional lighting sources, ActiveLED Lighting experiences no light loss

Austin, TX, March 22, 2011

commercial LED luminaires, announces that after three years of production and

installations, its ActiveLED

testament to its benchmark performance, efficacy and durability. Customers looking to

replace conventional, inefficient and noisy high pressure sodium (HPS) and high-intensity

discharge (HID) lighting for more sustainable, totally quiet lighting in manufacturing plants,

warehouses and other “high bay” facilities have turned to the ActiveLED High Bay Round

Light.

In Hillsboro, Texas, south of Dallas, Ringdale converted 250-watt HPS lights in the Hill

County Men’s Correctional Facility gymnasium to ActiveLED High Bay Round lights. “We

are very impressed with the light quality coming from the ActiveLED fixtures,” said Hill

County Chief Deputy Stephen Girsh. “Unlike the old lights, the ActiveLED fixtures provide a

crisper, more uniform light with softer shadows. We also look forward to passing on the

lower energy costs to our taxpayers.”

The 78-watt ActiveLED High Bay Round Light provides bright, uniform coverage while

saving up to 85% in energy consumption. With the ever-increasing rise in energy costs, the

High Bay Round Light “makes it a better hedge for the future,” said Klaus Bollmann, CEO,

Ringdale.

– Ringdale Inc., a leading U.S. developer and manufacturer of® High Bay Round Light continues to operate at no light loss, a

Rated at 90,000 lumen hours (24/7 is 8,760 hours per year), ActiveLED lights are the

longest lasting LED light fixture on the market, which also helps lower maintenance costs.

With the addition of Ringdale’s LightSpace

facility’s utility bill can be further reduced an additional 10-25%.

Another next generation energy efficient feature of the ActiveLED High Bay Round Light is

its “all voltage” (100V…277V) and 48V DC approach. The light can be backed up by a

Ringdale Battery Pack or be driven from a 48V DC power supply. This cannot be done with

conventional lighting technology.

Like all Ringdale luminaires, the ActiveLED High Bay Round Light comes with an industryleading

10-year warranty on its LED device and fixture and 5-year warranty on its power

source.
