A laminar flow jet is disclosed that provides a non-turbulent smooth stream of water. The jet is structured to remove turbulence from the moving water. As the water flows through the jet, a screen component and a nozzle component cooperate to slow the water flow and provide a uniform flow direction. The jet is also structured so that the laminar stream may be lighted from within the jet. The body of the jet is designed to receive an elongated and transparent probe carrying a lighting apparatus such as a fiber optic cable. The laminar flow jet is designed to be mounted to a structure such as a spa, pool or tub wall.
