For platforms, buoys and bridges the ML-140 continues its popularity Tideland’s ML-140 lantern is ideal for use as an aid to navigation wherever a wide-angle vertical divergence light beam is required. The use of wider light beams is recognised as an important factor in compensating for buoy roll. Visibility is also improved in locations, such as high bridges, where there may be extreme differences in the angle of observation at various ranges. The ML-140 is a single-piece injection moulding of acrylic with Fresnel optics specially designed to increase beam divergence in the vertical plane. Rigorous Tideland Signal guidelines for precise manufacture produce an excellent lens-to-lamp ratio, enabling the ML-140 to meet required luminous intensity levels while consuming less power.
