Bolt VB-22 Bare-Bulb Flash - Manual (Page 18)

18 | Setting the Flash Power
Setting the Flash Power
The VB-Series flashes incorporate manually-controlled power output that can be varied over 8 stops from 1/1
(full power) to 1/128, and is adjustable in 1/3-stop increments. Turn the Selection Dial clockwise to raise the
power level, and counterclockwise lower it.
To avoid overheating and damaging your flash unit, please wait for at least 10 minutes after 75 continuous
flashes at full power. The flash will automatically enter thermal protection mode if it gets overheated. The LCD
screen will display and flash firing will be disabled until the unit has cooled.
NOTE: Turning the flash power output lower than 1/128 until “OF” is displayed will disable flash firing. This
feature is for use with a dedicated remote, such as the Impact ControlSync 16. For more information, see the
Dedicated Remote Control section in Triggering the Flash, on the next page.
