I have two outdoor small format sodium lights. They are mounted on short 4x4 posts and serve to light up a small parking area near my cul de sac. I broke one of them off (non-repairable) and am looking for another small sodium light that would fit in its place. Does anyone know where I can find a sodium fixture that fits this bill? I can find fluorescent ones, but would really like to stick with the sodium if possible. Thanks!
