Don't forgot the Artiste Rembrandt has a Zoom Overdrive - this allows the zoom lens to go past its optimal narrow position, thus “overdriving” it.

The normal (default) zoom mode offers a narrow to wide beam with an even field for a great wash, both with the standard fresnel lens or the optional PC lens.

But when you want to experiment with a slightly narrower beam, try the Zoom Overdrive - Although this creates a slightly smaller beam, its efficiency is reduced. As the fixture may lose a bit of output when moved into the zoom overdrive range, it is mapped to the DMX range of 0 to 20; however, despite this reduced output, the resulting column of light, especially using the PC lens, is a useful effect.

The overdrive range is provided as a simple way for the operator to know the ideal zoom range for maximum efficiency.
