A Charleston-based company that imports and sells energy-efficient light bulbs, shower heads and other devices has purchased part of a Texas competitor.

AM Conservation Group said this week that the newly acquired business provides utilities and government customers with products that reduce their electricity and water bills.

The seller was Fort Worth-based Niagara Conservation Inc., which retained a division that makes high-efficiency toilets.

Financial terms were not disclosed. The sale closed in mid-December, according to a report on silobreaker.com.

"For over three decades, Niagara has been known as a strong water conservation company, and we are excited to gain access to offering their exceptional water and energy conservation product line, enabling us to market the best products from both companies," AM Conservation Group CEO Todd Recknagel said in statement.

The Berkeley County company said the deal will give its customers more selections and faster shipping options.

AM Conservation Group was established in 1989. It moved its headquarters to Charleston from New Jersey in 2005 and built a warehouse in Charleston Regional Business Center off Clements Ferry Road. Its founder sold the majority of the business in 2010 to Trivest Partners, a Miami-based private equity firm.

AM Conservation develops, manufactures and distributes more than 700 professional-grade products.
