User manual PROFOTO PRO DAYLIGHT

[. . . ] ProDaylight manual The ProDaylight lamp head is designed to be used with a 1200W "hot restrike" bulb, for instance the MSR 1200 HR manufactured by Philips or the HMI 1200 SE manufactured by Osram. When inserting the bulb, please check that the small bubble on the inner quartz tube is pointing upwards and when attaching the lamp head onto the stand check that the lamp head is turned the right way up. [. . . ] If air vents are lacking, leave the fastenings as open as possible around the base of the lamp head. If the bouncer is pointing downwards the fastenings must be secured tightly around the lamp head and side openings must be present and left open to let the hot air escape. The hot air will otherwise be drawn down and back into the lamp head causing it to overheat. UV-radiation The lamp head emits UV-radiation when fitted with most HMI/MSR bulbs.

Prolonged use will change the colour temperature and increase the risk of a lamp exploding. Ballasts The ProDaylight lamp head can be powered by two types of ballasts. Profoto's Magnetic Ballast which is available for various voltage conditions and Profoto's Electronic Ballast which has automatic voltage selection for all types of voltage. The Magnetic Ballast When used for still photography, the shutter speed should not be set to more than 1/90 sec. The Electronic Ballast The Electronic Ballast produces a flicker-free light, which allows any shutter speed to be used in still photography or when filming. It is also designed for the light settings used when "scanning" pictures and the long exposure time this requires. The light output can be reduced by 50% (1 f/stop) which will also increase the colour temperature considerably. The unit is normally used with the auto-start switch in the 'OFF' position, when it is 'ON' the unit will start automatically when the power is connected. [. . . ] Heat the bulb with a hair-dryer to pool the particles together and then try again Change to a new bulb ensuring that it is properly pushed into the socket.
