Pro 600W 400V HPS by Gavita

Make the most of your digital ballast and get a Gavita 600W 400V Pro HPS lamp! The Gavita 600W Pro HPS lamp has been designed specifically for use with digital ballasts. Digital ballasts run at a high frequency which can cause electrical resonance in the arc tube and cause the wire frame to distort. This lamp has an arc-tube designed for optimal output when fed from a digital ballast, and the wire frame has been re-enforced.
