A new “ultra-efficient” security and floodlight for mining and quarrying applications uses up to 70% less energy than the halogen equivalent and lasts 30 times longer, say makers UK-based Marl. The new light from Marl uses LED technology, and is described as an ideal solution for illuminating surface and underground mining operations. It offers mine and quarry operators a typical payback period of two years, as well as a greatly reduced carbon footprint. Designed and manufactured in the UK, the new Marl 748 series floodlight is just 10 cm deep, but delivers a massive 3,000 lumens from an input power of just 56 W, equivalent to a 200 W halogen floodlight. The floodlight has a rated life of 60,000 h, equivalent to over 13 years at 12 h per day. In this time, a halogen floodlight would need to be replaced 30 times, based on a standard life of 2,000 h. Marl is offering a five-year guarantee on the light.

Commenting, Adrian Rawlinson, Managing Director of Marl said: “Given that replacing a flood or security light normally requires the hire and use of an access platform, Marl LED floodlights can be justified financially on the reduction in maintenance costs alone. On top of that, they use significantly less electrical energy.” Marl 748 series floodlights are based on Osram Golden Dragon Plus LEDs, packaged in a robust die-cast, powder coated aluminium housing protected by tempered glass. The units are weather-proof, being sealed to IP66 standard, and are suitable for operation between -30°C and +45°C. Marl has designed the floodlight in accordance with world-wide electrical safety standards. An optional dusk-dawn sensor can be fitted to bring the light on when ambient light levels drop below a pre-set level. The 748 series is offered in four versions, with medium, wide, and extra-wide beams as well as an oval beam. It weighs just 8.1 kg.
