Not sure if you missed a comma, but Arc and HDS (now called Ra Lights) are different companies, and have been for a while. Although Arc and HDS had a history of making lights together as Arc, that has long since passed. But both companies are US-made lights (Arc & HDS/Ra Lights).
Yup, missed a comma.
But didn't know that HDS goes by the name Ra Lights now. Pretty cool name.
Do you agree that we should make a distinction between custom makers and regular manufacturers or should we just keep them together in one list?
I think I'll retract my own statement, since this list is about where the lights are made, not if they are made by a "qualified" manufacturer, as I misinterpreted the thread in the beginning. It's also not that easy to distinguish a manufacturer from a custom maker, easier to say where a light is made.
So I vote "no" on my own suggestion.
