About Mag Instrument

Mag Instrument, Inc. is the manufacturer of the world-famous MAGLITE® flashlight. For decades, MAGLITE® products have been recognized worldwide for quality, durability, craftsmanship, and American manufacturing.

Mag Instrument, Inc. is an Equal Opportunity Employer.

Mag Instrument, Inc. was started in 1955 by the President and founder of the Company, Anthony (Tony) Maglica. Mag was first housed in a small private garage with only one employee, Mr. Maglica. Today, in contrast, the Company's operations are spread over eleven different buildings totaling almost 700,000 square feet.

Established in 1974 Mag Instrument, Inc. (Mag) is a family-owned manufacturer of the premier Mag-Lite® line of portable lighting products. It is by integrating the latest in manufacturing methods along with our dedicated, involved, and knowledgeable people that provides Mag with the edge that makes us the best in our field. Every Mag Instrument flashlight, no matter where in the world it ends up, originates from the manufacturing facility in Ontario, CA.

Mr. Maglica utilizes a hands-on leadership style with a core philosophy-consistent and superior quality of Mag products, outstanding customer service, integrity, honesty, innovative production and business processes, and fair treatment, respect, and equal opportunity for all Mag employees.

The success of Mr. Maglica's philosophy is evident by the recognition and awards Mag has received. Mag products were named "one of the 99 best products America makes best" by Money and Fortune magazines. Additionally, in 1996, Mr. Maglica was named Entrepreneur of the Year for the Southern California Inland Empire.

Mag's quality has not only been recognized in America, but Mag also has been the recipient of international design awards in Japan and Germany. This international recognition has made Mag products known world-wide and Mag's international business has grown steadily over the past several years.

Mag is proud of the fact its portable lighting products are designed in the U.S.A. and produced by American workers. Mag has withstood the upward pressures on its prices - having never increased prices to its customer since 1979. By continually implementing innovative production and business processes Mag has also been able to resist the temptation to "outsource" its flashlight manufacturing outside the U.S.A.
