Surprised to hear objections to this thread - no sales pitch here - just an attempt to stimulate some thinking about how pros can make decisions on wire gauge for their projects - keeping in mind the desire to save energy and the desire to lower costs for thier clients.
In my view, it is critical for pros to fully understand the electrical calculations of voltage loss and energy consumption - these calculations are different for LED's - and getting this right is essential for today's priorities - energy and cost savings.
I view this forum as addressing the art, business, and technology of architectural and landscape lighting. As pros, we need to be experts in all three, and this forum is a great venue for that.
