Chalmit Micronex and Maxinex Floodlights Details

The maxinex and micronex form a range of zone 2 floodlights providing excellent photometric performance. The smaller micronex is for 70W double ended high pressure sodium or metal halide lamps and the larger maxinex is for 150W to 400W tubular high pressure sodium or metal halide lamps. The hazardous area protection is Ex nR utilising a restricted breathing enclosure. 

The asymmetric distribution enables areas to be lit more efficiently with less glare or light pollution. This is because the beam is thrown a long distance whilst avoiding excess light levels under the mounting point and having a precise cut off angle. 

Available with a choice of either a narrow or wide beam reflector, the micronex and maxinex offer the opportunity for very effective and efficient lighting schemes to be designed. The enclosure is a robust high pressure die-cast aluminium body with a toughened glass cover in a hinged frame with stainless steel fasteners. The compact design ensures reduced weight and has low windage which helps lower installation costs as it allows more economical support structures. Suitable for a wide range of ambient temperatures, -40°C to +55°C, dependant on lamp type and wattage.
