Don't confuse these with those cheap plastic lamp posts that you happen across at your local home improvement center! These are commercial grade quality. Our posts are formed from quality cast and extruded aluminum complete with ultra-durable black powder coating and stainless steel fasteners. Each pole comes standard with a polyethylene globe that is highly vandal resistant, and in fact can be bounced like a basketball! Installation instructions are included, but it is probably a good idea to use a contractor unless you are very confident . . . especially with the wiring. And remember . . . technical support is included at no extra charge!
