The Rembrandt 2500/4000 W is a unique step forward in lighting technology. The results of an extensive research from De Sisti, it utilizes a single ended discharge lamp which allows significant reductions in both size and weight without compromising its output and ensures a smooth uniform field through the full range from Spot to Flood focusing. The use of the single ended shotr arc discharge lamp enables the unit to substantially outperform both the light aoutput and the beam spread of cinventional 4000 W discharge Fresnel spotlights using double ended lamps. The Rembrandt is a perfect key or fill light for studio use when colour balancing to 5600° K and is the only choice for location work where size and weight versus output are always at a premium.
