Our standard LEM lanternhouses are cylindrical and with semispherical dome. Its cylindrical structure provides two key advantages over other manufacturers’ lanterns: helicoidal uprights to avoid dark areas and give sturdiness, and curved-glass panes to minimise refraction losses and reduce back reflections.

Furthermore, we can manufacture any LAM polygonal lanternhouse, strictly according to the customer specifications.

MLL 1000 lamp

The MLL 1000 lamp, developed and patented by MSM, is a luminous equipment with the highest LED technology. While others LED lamps of the market, those are characterised by their use of a virtual light source. The light emission is made through prisms to a hyperbole, in such a way that the light source is virtualised in the exact in focus point lens, as a filament or metallic halogen lamp. Thus, the focal distance of the lens is maintained and it can replace any traditional lamp of the market. Ideal to be installed on classic glass optics, both rotating or flashing lighthouses. Its main advantages are: its significant energy saving (and consequently the environment preservation), its service life (up to 100,000 hours) and its easy installation, as diesel generator, current inverter system and less capacity batteries are not necessary.
