M-250A2 FCO Installed On a 6ft Tapered Elliptical Arm!

I decided to replace the cantilever pipe arm with one of my two nice sturdy tapered elliptical arms. I kept the same fixture out there though, my 250W MH/MV M-250A2 FCO with a newer Chinese Sylvania /DX lamp. This set-up is rock-solid now! I used a few square utility-grade washers around the thru-bolt behind the arm to fill in the gap between the arm and deck post, as the arm's bracket is curved for a utility pole. The tapered arms also adds another 8-12" inches of height to the light too.
