What floodlights to choose for lighting a sports field?

We organize a sports ground, we need to arrange lighting using spotlights. As supports, profile pipes 80x80 6 m high are used. Pipes are straight, without rounding at the top, with a plug. Mounting is possible on self-tapping screws, anchors, etc. Tell me, which spotlights can be used in this case? You need 6 pieces with a capacity of about 100 watts. The size of the site is 26x14 m, that is, the lighting area is about 360-370 m2.
