So I’ve heard of LED lights being super efficient and«Green» for awhile now but never really thought much about it. Finally after checking out the LEDs on the bay bridge I googled it and found Green Ray LED had an SF office here in the north beach –fisherman’s wharf area. I called them up and they offered to do a «free energy audit». They actually sent their Rep over to my office to check out my current lighting setup and how much energy Im using. The rep was here for maybe 30min or so counting my lights and asking questions about my preferences. He left and in a day or two he sent me back a pretty extensive evaluation(This thing listed ROI, net present value, payback period… etc) detailing the LED costs & energy savings vs my current fluorescent setup. Financially it made sense so I converted most of my lighting over to LED. It’s all set up now, I learned more about lighting than I’ll ever need to know, the lights look great and I’ve had no problems. I’m more than happy with these guys so far.
