By Green Dog Pet Supply When we first opened, one of the things we thought was a no-brainer was looking into LED or other efficient lighting options for the sales floor. As the first environmentally friendly pet supply store in the nation, we wanted to make sure that we did everything we could to design for sustainability. The spotlights seemed to be a challenge though. LED technology has come a long way, but at the time, most LEDs were kind of blue in color, and not very bright at all.
