If your looking for a specific bulb or light this is the place to go! Great staff and very knowledgeable!
I have used FSG for numerous projects. They have been great business partners on our many projects.
They are one of the few places I could find that will recycle fluorescent tubes, specifically the 8′ variety. They’re quite a bit cheaper than one of the chain stores around here that also would do that.
Great service. They know their stuff. Great for commercial lighting needs
