Power is from a ni cad pack. Alkalines cannot be used. Please note that neither the charger nor battery are included - they must be purchased separately. The 104 is supplied with tray, straight arm and interchangeable cable. THE 104 charger is dual voltage and can recharge two SB104 power packs simultaneously.
Recharge time is about two hours with one power pack and four with two attached.
THE dedicated ni-cad power pack for the SB104 will provide around 120 flashes at full power with a recycle time of about 3 sec. THIS diffuser fits both the SB103 and SB105 to increase the beam angle to cover a Nikonos 15mm lens. It reduces power by one stop. Extension arm THIS arm attaches to a standard speedlite straight arm to place the strobe further away from the camera to reduce backscatter or to allow the strobe to be moved into a range of positions for more effective lighting control. For details please refer to the Sea and Sea and Subal guides.
