AUSTIN, Texas and SAN SALVADOR, El Salvador, January 27, 2011 - Ringdale, Inc., a global leader in the development of intelligent
LED lighting technology, and Clean Technology Solutions (CTS) LLC, a major
distributor of energy efficient technologies in Latin America, today
announced the first sale of Ringdale's ActiveLED(R) line of commercial
lighting fixtures in the region. CTS was successful in selling ActiveLED 2' x
2' Recessed Ceiling Panel Lights and Recessed Ceiling Downlights to an
office building in San Salvador, El Salvador.

Ringdale and Clean Technology Solutions recently signed an
agreement to have CTS exclusively distribute the ActiveLED product line to
the rapidly emerging green building market in Latin America.

"We are excited that our partnership with Ringdale to bring
ActiveLED to Latin America quickly resulted in the completion of a sale that
will significantly lower our customer's energy costs," said Adolfo Salume,
CEO, Clean Technology Solutions. "ActiveLED, which offers the broadest range

roadways, parking structures, billboards, building exteriors, warehouses,
offices, retail spaces, parks and restaurants. The fixtures deliver better
illumination and use 50-95% less energy than fluorescent, incandescent,
high-pressure sodium and other conventional light sources, and last far
longer.
