American-Made Lighting. Backed by 85 Years of Manufacturing.

Amersol Supply LLC is a Wholly Owned Subsidiary of Koller Enterprises, a third-generation family business with over 85 years of manufacturing excellence. The Koller team has been producing precision components for companies like Ford Motor Company, Kubota, Coca-Cola, and AMC Theatres for decades, and designing and building fixture components for the biggest names in commercial lighting for over 55 years.

Amersol was created to bring that same manufacturing DNA directly to the distribution channel: specification-grade, American-made LED luminaires backed by the people and processes that actually build them.

Our Mission

To deliver quality American-made LED lighting through a curated product line, standout service, and an ordering experience built around the way distributors and reps actually work.

What Sets Amersol Apart

Integrated Engineering. Designed for thermal performance, lumen maintenance, and fast installation. Tested and refined before it ships.

Onshore Manufacturing. Built in Fenton, Missouri. Shorter lead times, transparent sourcing, and quality control feet from our desks.

Quick-Ship Inventory. Spec-grade product stocked in St. Louis. No 12-week wait.

Direct-Access Support. Call us, talk to the people who built your fixture.

Built for Reps

Multi-tier pricing. Competitive rebates. Flexible stocking programs. We’re building a rep network and looking for partners who want a manufacturer that picks up the phone.
