ProTwin

The ProTwin is used to obtain extremely short flash dura- tion, very quick recycling or to get up to 4800 Ws out of one single head. There are two flash tubes in a ProTwin. As the flash duration is shorter at low power settings, and as only half of the desired power is used in each tube, consequently shorter flash duration is obtained. For example if you need 1200Ws, you fire 600 Ws from each tube, and your flash duration is shorter than if a standard ProHead is used. The flash duration at 1200 Ws with a ProHead is 1/2200 while it is only 1/3200 with a ProTwin. One or two generators can be used.

If, on the contrary, you require 2400Ws from one head you connect ProTwin to two Pro-B2/1200 generators. For the same reason shorter recycling times is obtained when two generators are used, as the recycling is faster when the generators in fact only need to recharge half the energy. Flash duration and recycling for a ProTwin at a certain power setting - for example 1200 Ws - compares with a ProHead set at 600 Ws.

The modelling light is turned on and off with the black switch [1] at the back of the head. The built-in fan is a thermostatically controlled 2-speed fan ensuring mini

mized sound level and efficient cooling in all situations. Please note that when changing modelling light, flash tube or glass cover the lamp cable must be disconnected from the generator.

The modelling light has a mini-can socket (E11). The flash tube has two metal pins. When removing a flash tube, pull it straight out of the sockets. When inserting a new flash tube, check that the trigger-wire clasps properly around the flash tube (please see mounting instructions in package). When mounting the glass cover, check that both locking springs connect properly into glass cover holes. In case the head overheats the modelling light automatically switches off. When the temperature has dropped sufficiently the modelling light will switch on again. At the back of the head there is a thread for attaching accessories like handle (std. with head) or a flex arm (Magic arm) to hold filters etc. There are glass covers for different colour temperatures available.

When used on the Pro-B2 it is strongly recommended to change from a 500W to a 250W lamp for increased efficiency due to the fact that the B2 delivers max 250W to the lamp.
