On account of their robust design, in-ground luminaires are frequently found in public areas. All light characteristics are possible with light from the ground – from location lights to adjustable floodlights. A very high protection class of IP 68 allows the luminaires to be exposed to long-term flooding. A water column of up to 10 m is possible. The luminaire design made of stainless steel and cast stainless steel is so robust that the luminaires can be driven over with pneumatic tyres. The pressure load can be as much as 5000 kg.
