Prolume was established in 1994 and has provided custom fixtures to the lighting industry for over twenty years.  The company originally focused on exit signage.  The advent of LED technology lead to a new focus upon custom quality LED fixtures.  Because of a clear understanding of specifier and architect needs, Prolume developed a portfolio of unique and versitile LED products.

Today, those products help showcase many museums, bridges, churches, restaurants as well as commercial and residential venues.  This is accomplished through impeccable attention to detail as well as quality.  Understandably, Prolume has gained the trust and respect of the LED lighting design community, and is repeatedly specified with confidence worldwide.


In January 2016, as a result of collaborating for over twelve years on numerous projects that focused upon new product development and custom LED fixtures, Prolume was acquired by LEDdynamics.  Furthermore, LEDdynamics is a privately held LED technology company that is located in Randolph, Vermont. Their LED linear fixtures are designed and manufactured in the USA.

Consequently, this Made in America offering provides them with a value and market differentiation in contrast to international solutions within the highly competitive LED marketplace.  Finally, by leveraging the core competencies of each organization, Prolume continues to offer innovative LED fixture solutions for the lighting industry.

As a result, their product portfolio is frequently selected as the optimum choice for illumination and they excel at assisting light specifiers to convert visions into reality.
