Q-Tran is committed to providing innovative LED products and the best power supplies for exacting applications.

John Tremaine started his lighting career in 1970 with his family’s lighting business, The Miller Company, acquired by his grandfather in the early 1930’s. John’s great-grandfather founded the National Electric Lamp Association (NELA), which became General Electric’s lamp division in Cleveland, still in use today as Nela Park. Lighting design became Tremaine’s greatest interest. In 1980, he started his lighting design practice, Tremaine Lighting Design. Five years later, he opened a high-tech lighting showroom, “PRIMO,” providing customers with a creative alternative to functional lighting.

In 1990, John Tremaine noticed a need in the lighting industry for remote transformers able to eliminate noise and heat, enhance the quality of light output, and install with a degree of flexibility.

Through his experiences in the lighting industry, Tremaine discovered a flaw in the standard power supply centers. Frustrated with the performance and quality of the existing power supply centers, Tremaine designed a product addressing all the issues previously ignored: safety, reliability, performance and convenience. The result: the patented Q-Tran Power Supply Centers.

With a family background in manufacturing, Tremaine started producing his Power Supply Centers for his design projects. The Q-Tran Power Supply Centers succeeded locally and went to national distribution in 1995 and, shortly after, went to international distribution. In 2012, Q-Tran developed an entire line of DC power supply centers for interior and exterior LED applications and in 2013 started selling linear LED lighting to compliment its power supply center business. Q-Tran continues to innovate and operate under the concept of "Enlightened Thinking®."
