Does anyone use those I’m not sure what thier called but I’ll refer to them as goosenecklamps for the voyager?
Wasn’t sure how they worked. I thought some voyagers had a dial to change thier intensity. I might be wrong. I thought that was on certain voyagers but not on all of them . My lunar impact doesn’t have the dial. I don’t know much about them would appreciate any information on them thanks
