We are a family business comprised of Interone (Korea),
E-Power (Korea), Intellect-LED - formerly Interone USA (California), E-Power America (California) and Sign Supply Co (Las Vegas). We specialize in LED modules & power supplies for the US electric signage market.

Our LEDs and power supplies are manufactured in Korea, are fully UL certified and are distributed throughout North America under our OEM branding and private labels.

Interone Korea was founded in 2005 by my uncle, June and we have since distributed Interone LED across the entire globe in numerous countries. Sign Supply Co was established in 2022 to further serve the US market with additional materials.

Above all, we value honesty - even before profit. Enduring relationships require honesty and all business is doomed to fail without trust.

We value relationships with all people - from vendors and employees to customers of all sizes whether it is a large sign shop or a DIY project.

Treat all living beings with honor and respect - good business will follow.
