Karl, I'm not familiar with the light, but it sounds like the 10-pin is a power pack connector and the "AC" is a plug-style trigger (TTL?) -Jason -----Original Message----- From: owner-photoforum@listserver.isc.rit.edu [mailto:owner-photoforum@listserver.isc.rit.edu]On Behalf Of Karl Shah-Jenner Sent: Sunday, June 23, 2002 12:20 AM To: List for Photo/Imaging Educators - Professionals - Students Subject: Bowens prolite question Hi everyone, I have a Bowens Prolite 60 in my possession and I'm trying to find out something about the power supply - it takes both AC and it has a plug on the back which suggests it also can be operated from a battery source. Does anyone here know anything about these units? Specifically I'm hoping someone could tell me what the actual power requirements are for the battery, and how it's connected through the ten pin connector on the back Karl
