Aye, thats the way to do it. i still got some lightforce lamps from about 15 years ago, and they're going strong, but only after a bit of messing about with the wires. Which, truthfully, you shouldn't have to do to a lamp. It should work straight out of the box.
This is the set-up I use these days for lamping. It's kind of evolved over the last decade into this, it's a real chew humping it about but it's the only way to get the photos I want. Luckily for me my dog doesn't need a lead....
Good set up that Jd did you make it yourself,I bet it took some getting used to.
