The cover glass of the bollard luminaire is fully concealed from view. A lens spreads the light onto the ground but also illuminates the cross-shaped aluminium profile to provide a discreet focal point. The Midipoll bollard luminaire for LEDs uses a recalculated prism lens made of plastic.

The light of the high-power LEDs directed perpendicularly downwards is guided by refracting the light on the upper and bottom side of the lens to result in a wide light distribution on the ground.
