Realistic industrial product render, a long rectangular hanging industrial light fixture centered on a light gray-white plain background, straight-on front view. The housing is dark olive-green aged metal with a long rectangular body, thick metal edges, and a vertical protective metal grille underneath; a small central junction box and exposed wire sit above the housing, with two dark metal chains rising vertically to square ceiling mounts on the left and right.
