"CAUTION: When installing the halogen modelling bulb make sure that you DO NOT touch the bulb with bare skin.

Please use a clean piece of dry tissue, gloves or the plastic covering that is on the halogen modelling bulb when installing, remove the plastic covering when the bulb is installed."

Yes! All our Interfit flash range will have optical sync which will enable your flash to be triggered by another light source, simply set the mode to CELL and your [HB320/HBU250/INTS1/INTS1A] will be fired by another light. Cell mode works on the speed of light, for best results use a direct line. Please note, on this mode you cannot control HSS or TTL.
With the sync cable that comes with the [HB320/HBU250/INTS1/INTS1A] plug it directly into the PC Sync Socket on your camera. Entry-level cameras do not have these, but you can buy an adapter. Like cell mode, you will not be able to control HSS or TTL using this method to fire the lights.
Check that the hotshoe settings on your camera are set up correctly, refer to your camera’s user manual.
Please also make sure all contact points on both the camera and trigger are clean and are not damaged.
We cannot guarantee any third-party equipment will work with our Interfit lights as they would not have been tested. If they do work, it is not guaranteed that you will be able to control HSS and TTL functions with them.
Yes, but like with any socket do not overload the extension lead and make sure it is a properly rated, surge protected extension lead.
Yes you can use your [HB320/HBU250/INTS1/INTS1A/Monolight/F121] in Europe.
Please ensure that both the light and the trigger are up to date with your camera model. You can find firmware here. You could be over firing the flash, the higher the setting of the light intensity, the longer the flash tube will take to recharge.
You could be over firing the flash, the higher the setting of the light intensity, the longer the flash tube will take to recharge.
