Functionality
Metal halide lamp
The ProDaylight 800 Air unit is equipped with a powerful metal halide lamp, providing
daylight color temperature.
SAFETY PRECAUTION!
Profoto only uses UV-doped CSR-lamps, which emit a fraction of the hazardous UV radiation compared to classic
HMI type lamps. Never use other types of lamps than the ones specified by Profoto.
A cold metal halide lamp does not immediately begin producing its full light capacity. The
warm up period can be a few minutes. During that time, the color of the light will vary.
If the ProDaylight 800 Air unit is turned off, it takes about two minutes before the warm
lamp can be turned on again. It is recommended to let the lamp run for at least
15 minutes
after turning it on, since turning the lamp on and off repeatedly considerably reduces the
life time of the lamp.
Glass cover
Metal halide lamps operate under high pressure and temperature and require special
safety measures. The ProDaylight 800 Air unit is equipped with a protective glass cover,
which protects from lamp shatter and UV radiation. Unless the glass cover is correctly
mounted (see page 13) it is not possible to turn on the ProDaylight 800 Air unit.
SAFETY PRECAUTION!
A damaged (cracked or scratched) glass cover must never be used! The level of UV protection provided by the glass
cover is matched to the lamp type specified by Profoto. Only use Profoto specified lamps.
The protective glass cover is available in different versions; with frosted and clear glass
and with different coatings for distinctive color temperature adjustments.
Reflector
By mounting a reflector and placing it in different positions, using the Zoom Scale [12],
several light shapes can be created for each lighting purpose. The unique rubber collar
fastening system provides secure and rapid handling of the reflectors, also when hot.
Light intensity
The current light intensity is shown in the Display [1], in percent (%) of maximum light
output.
The Setting Knob [6] is used to adjust the light intensity, in 1% or 10% increments.
