BETALUX PRISMATIC LUMINAIRE Very Low Mounting Height wide spread lighting for Commercial and Industrial Applications Applications BETALUX was developed to take advantage of the super efficient lamps (250 Watt metal Halide or High Pressure Sodium) used at very low mounting heights (3-6cm) and means that energy costs can be slashed compared to Fluorescent or Mercury Vapour installations - lower power lamps can be used if desired.

The BETALUX ability to provide a radial 'bat wing' light distribution sends light where you want it, i.e. onto vertical surfaces, into shelving and display gondolas, under equipment and penetrates into enclosures, engine compartments and trucks etc. BETALUX is designed to be spaced far apart (up to 3 times mounting height) thus further reducing costs, installation and energy consumption. The superbly designed refractor is a model of even flashing and redirectional prisms which allow light to reach into the darkest recesses. Perhaps most important of all, people look good because of the soft modelling effect inherent in a more horizontal emitted light. Intense reflections are also supressed - in short better quality lighting.

Features - The BETALUX Control Gear Housing and Reflector are constructed from heavy gauge zinc coated steel and finished in extremely hard wearing powder coating finish. The injection moulded acrylic refractor is held tight to the reflector compressing a neoprene extrusion thus sealing the optical chamber (meets requirement of IP65). This chamber is allowed to breath through an activated charcoal filter thus keeping the interior free from contaminants during the hot/cold lamp switching cycle. There is a safety link between the refractor and the reflector to prevent accidental dislodgement during relamping.

BETALUX can operate in ambients up to 45oC. and higher if the remote control gear version is used. The injection moulded Acrylic non yellowing refractor is secured to the reflector by low profile stainless steel clips allowing rapid lamp change from below. BETALUX can be recessed using a regressed metal panel sitting neatly into the standard 600 x 600mm 'T' Bar ceiling or can be surface mounted or suspended. Overall height can be reduced by remote mounting the control gear housing and replacing it on the reflector by a shallow casting. Max weight 10kg. BETALUX is fully sealed and the optical chamber breathes through a filter keeping the performance in an 'as new' condition. BETALUX should be considered for use in retail store areas, shopping malls, store and despatch areas, low roof factories and assembly areas, food processing areas, (BETALUX is D.P.I. approved) aircraft and transport servicing departments, paper and textile industries.
