•Spec Sheet: Megaray High Intensity Spotlight

Megaray is a high intensity spotlight for police, military and special forces that sees beyond 6000 feet with 11 million candlepower.

Megaray's light beam can be switched to three different mode settings by means of a three-position mode selector switch situated on the bottom front end of the light unit. The three different selectable modes are low intensity, high intensity and strobe. A fourth "mode" in which Megaray can be used is the "IR (Infra red)" mode.

Low Intensity mode
Low intensity mode is selected by switching the selector switch to the foremost position when the light is held in the normal operational position. This setting is intended for situations where less intense light is required. When Megaray is used to illuminate objects over shorter distances, this mode is suggested. In this mode, battery life is also extended because of reduced power consumption. When Megaray is pointed at highly reflective objects, the reflected light can partially blind the user so that the object cannot be clearly observed. In such cases low intensity mode can be selected to reduce reflection. Vehicle registration plates in some countries are made of a reflective material. Low intensity modes will make it easier to read vehicle registration numbers.

High Intensity Mode
This mode is selected by switching the mode selector switch to the centre position. High intensity mode produces maximum performance and maximum illumination range is achieved. Apart from general illumination of objects, this mode can also be used effectively during crowd control operations. Adjusting Megaray to the minimum beam divergence — ie. with the lens holder moved to the foremost position — a single person or small group of persons in a crowd can be pinpointed without disturbing the rest of the crowd.

This mode can also be used by utility maintenance teams to inspect industrial installations and heavy gear by night. A damaged insulator or open trip switch on high voltage overhead gear can be easily identified at night from a long distance. Megaray can also be used to look down mine shafts or deep holes. Search and rescue units can now scan the mountain rock face for lost mountain climbers from across a ravine or gorge, without having to first cross such obstacle.

"Strobe" Mode
This mode is selected by switching the mode switch to the foremost position. In this mode the power supply circuit modulates the light to flash at 8 cycles per second (8 Hz) with the beam in high intensity. This mode is intended for house penetration operations and riotous conditions. When a very intense flashing light is directed at rioting people, it has a disorientating and blinding effect on them. They tend to loose their balance and cease whatever actions they were busy performing. In general this this effect is however not permanent and is unlikely to injure people.

IR-Mode
To use Megaray in this mode, one of the two Megaray IR filters needs to be attached to the front of the lens housing. The filter is clip-on and is attached very easily by simply pressing it on or pulling it off. When the Infrared filter is attached, Megaray's light beam is hardly visible to the naked eye. Standard night vision equipment is required to be able to see Megaray's infrared beam. The type of Xenon lamp used in Megaray generates particularly high light energy in the infrared region of the electromagnetic spectrum.

This makes Megaray a very effective illuminator for covert observation. The quality of observation will be determined by the quality of night vision equipment used in conjunction with Megaray. Megaray has been successfully used from a helicopter platform in the infrared mode. Although night vision equipment renders much improved visibility in the dark under normal star and moonlight conditions, deep shadows and dark areas are still encountered. Megaray in the IR mode is used to fill in these shadows and dark areas to greatly improve the effectiveness of observation using night vision equipment.

The basic difference between the MIR-102 (semi-covert) and MIR-103 (covert) filter is that the MIR-102 filter filters out less light than the MIR-103. Generally 2nd generation night vision equipment renders good results if used in conjunction with both the IR filters. However, the same range is not achieved when the MIR-103 filter is used. The effective range of the MIR-103 filter is improved when 3rd & 4th generation night vision equipment is used.

Snipers using IR scopes can make good use of Megaray in the IR mode for target illumination at night. This comes in handy during hijacks and hostage situations. Megaray can be mounted to a tripod next to the sniper with the beam focussed on the target, or a second person — also using night vision equipment — can illuminate the target for the marksman.
