Exterior Projection 500 User Manual 27
Operation
The Exterior Projection 500 is designed to operate at ambient temperatures between -30°C (-22° F)
and 45° C (113° F). For instant wake-up with no warm-up mode, we recommend that you keep
power applied constantly in ambient temperatures below 0° C (32° F).
If the fixture’s temperature rises above its normal operating range, its light output is regulated. If
the ambient temperature rises towards the 45° C maximum and/or if the fixture is exposed to
strong sunlight, for example, output intensity will be reduced in order to protect the fixture.
Projection data
When projecting a gobo with an image of maximum size at a perpendicular surface (i.e. tilt angle
0° relative to the surface), you can obtain the following image sizes and light intensity in the
projection:
