Modularity
Advanced design for in-ground lighting

The challenge of placing in-ground floodlights in hostile environments – in contact with soil, water and chemicals – whilst maintaining efficient cooling, excellent performance and safety is demanding. The complete M9000 Series luminaires consists of modular components that have been designed to assist in installation, maintenance, accessibility, interchangeability of components, long life and most importantly safety. Water penetration is not a problem, as all the critical components – lamp, ballast and connectors – are installed as pre-sealed watertight modules.

Cooler Operation
Double lens arrangement

The removal of heat from the luminaire helps protect the life of components whilst ensuring lens temperatures are kept to minimum, an important consideration where the potential exists for human contact. The M9000 Series is unique to other in-ground floodlights by offering double lens optical arrangements. Single lens fixtures have limited applications, due to the higher lens temperatures they produce. The M9000 Series offers a unique double lens option that can reduce lens temperatures by up to 40ÞC, allowing for a much wider range in applications. The double lens concept works by the initial lens absorbing high percentages of the heat. The area between the two lenses acts as an additional insulating layer, further reducing heat build up on the surface lens. Double lensed models provide an insulating layer of air for additional cooling.

Convection cooling

Conventional recessed sealed luminaires are dependant mainly upon conduction and radiation for cooling. The M9000 Series, however, also applies convection for cooling by incorporating chimneys within the rough-in section. This allows better circulation of the air as it is heated. The heated air rises and exits through the door vents, which in turn draws cooler air in through the chimneys, thus cooling the Acralume™.

Easy Aiming

Conventional recessed up-lighters are often restricted when it comes to aiming. This makes it difficult to achieve precise aiming when trying to highlight specific features. The double lens option can be rotated through 360Þ with a lockable tilting device allowing ± 15Þ tilt movement. This can be combined with optically active lenses to achieve up to 35Þ beam offset.

The M9000 offers two lockable aiming options:

• Single Lens – Optically aimed active lenses with a rotatable Acralume™.
• Double Lens – Mechanically aimed tilt and rotatable Acralume™.

Easy Maintenance

The M9000 Series has been specifically designed to reduce maintenance times. A common problem with in-ground recessed luminaires is the penetration of foreign matter during maintenance. Conventional in-ground luminaires consist of a gasket seal and a number of fixing screws. Misalignment in the tightening of these screws will jeopardise the IP rating of the luminaire leading to condensation build up. Hydrel M9000 luminaires have a factory-sealed reflector module (Acralume) complete with lamp, so it does not have to be opened on site by the installing contractor. Thanks to its modular construction, with the M9000 Series all maintenance can be conducted away from site in a clean environment.
