CeeLite L.L.C., which manufactures flat, flexible lighting called Light Emitting Capacitors, announced today it has raised $4 million from a private equity investment.

The Blue Bell company said the Musser Group provided $2 million, and the other $2 million came from private unnamed investors. The Musser Group, based in Wayne, will have two seats on CeeLite's board.

CeeLite's lighting is paper-thin sheets of plastic layered inside with phosphors that, when charged with electric current, emit bright white light. The lighting can be cut, twisted and wrapped around almost any surface indoors or out. The technology can be used to illuminate pillars, countertops, floors, billboards, street signs and transit buses.

CeeLite says it is the first commercial manufacturer of LEC technology. The firm plans to use the funding to expand and build a manufacturing plant in the Philadelphia area next year.
