A south Forsyth division of an international light bulb testing company opened an expanded facility Tuesday.

CSA International held a ceremony unveiling its new 30,000-square-foot testing facility on Shiloh Crossing.

Rich Weiser, vice president for United States and Mexico operations, said the facility is about three times the size of the company’s former site on Justin Trail in south Forsyth.

CSA opened its Forsyth location in 2005. At the time, it was 8,000 square feet.

“This facility will allow one-stop shopping for testing and evaluations for our clients,” Weiser said of the new venue.

He said CSA International provides various testing of light bulbs for more than 7,500 customers.

“At this particular location, we test for about 250 to 300,” he said. “Those include light bulb manufacturers and big box retail stores.”

The new laboratory will provide testing and certification of LED and other lighting products, as well as required third-party Energy Star testing.

Weiser said the facility has the capability to test thousands of lighting products simultaneously for safety, light and heat output, endurance and dispersion.

Products tested in the facility, he said, will include those used in automobiles, boats, airport runways, flashlights and streetlights.

He said besides testing of sample products, CSA International employees also visit manufacturers to ensure all bulbs are being produced using the same standards as the samples certified.

Weiser said the lab currently employs 11.

“But we’re expandable to 30 to 35 positions,” he said. “We have a three-year business plan in which we’ll grow to those levels.”

Weiser said the new facility represents a more than $2 million capital investment, including the equipment housed inside.

The site also has some 10,000 square feet available for future expansion.

James McCoy, president and CEO of the Cumming-Forsyth County Chamber Commerce, welcomed the new facility during Tuesday’s ceremony.

“We’re very proud to have you in Forsyth County,” McCoy said. “We’re very willing to partner with you in your future growth and development.”
