My EE Tunnels are typicaly lit with a single row of MH lights down the center.
Unlike Full serve where a double row may give better lighting for the sides of the car especialy when viewed from a customer walkway having the row down the center seems to be plenty.
Typicaly lights are spaced about 15 feet apart starting about 6 feet in from the door. Of course no lights over mitters because they would block the lights so the 15 feet is an approximation. This means a 100 foot tunnel uses about 6 lights. My older locations have 400W and newer 320W with one having a mix.
Anyway, since an equip reconfig required me to take down 2 400W MH I decided to experiment and replace withe these LED's

The Tunnel has one wall being mostly exterior windows so I haven't seen it at night yet, but the daytime results are outstanding. With a cost savings of maybe $100 / year the payback time for electricity at about 6 years (perhaps shorter if Ballast and Bulb costs are considered) makes me want to wait before simply changing out the rest, but antime I need to change a Bulb and Ballast on an old light I may consider changing to this.
