Motorized Barndoors
Overview
The motorized barndoors are available as an individual lighting device, or they may be purchased as an accessory.
When acquired as an accessory, the motorized barndoors quickly transform the G-4 into a Fresnel-based luminaire with the same
projector performance and no need of manual adjustment.
The motorized barndoors are operated remotely via DMX. Each blade has individual -90º to +40º angle control, and the whole module
rotates from -110º to +110º. The barndoors maintain their position at any time and the automatized control avoids the blades to be
damaged.
Unlike other LED fresnel lights, the G-4 Wash Motorized Barndoors uses a glass Fresnel front lens and the size of the luminaire does
not change while using the zoom feature. Like the traditional hand-made Fresnel projectors, the G-4 Wash Motorized Barndoors
creates sharp defined shadows in flood position and diffuse silhouettes in spot position.

Interchangeable front lens
The G-4 Series offers the possibility to change the front lens, expanding the flexibility of the luminaire even further. A G-4 Wash can
quickly be converted into a G-4 Wash-Beam, or in a G-4 Wash with Motorized Barndoors.
Changing the front lens
To replace the front lens:
1.
Locate the four screws on the front head.
2.
Remove the four screws with a Torx 20 screwdriver.
3. Detach the front lens in a firm grip.
4. Mount the new front lens and tighten the screws with 1 Nm.
Make sure the rubber sealing O-ring in the front lens (not
shown) is located correctly and it is not damaged.
