Remote Control Search Light – Dual Mode

Remote Control Search Light – Dual Mode

A vehicle-mounted remote control spotlight with two light sources in one head: a 320,000 candela white LED reaching over a kilometre, and a covert 940 nm infrared LED on the same 8° beam. The operator switches between them on a dash-mounted rotary switch and aims with a joystick, without opening a window or leaving the vehicle.

The 940 nm wavelength matters. At 850 nm an infrared illuminator produces a faint red glow at the emitter that is visible to anyone looking at it. At 940 nm there is nothing to see, so the beam exists only for observers equipped with night vision. A crew can search, identify and track without disclosing that anything is being lit at all.

Key Features

  • Dual illumination, visible and infrared, from one head
  • Hard wired dash control, so nothing depends on a battery or a pairing
  • Programmable home button returns the head to a preset position
  • Weather-tight enclosure
  • Carbon fibre and ABS body
  • Separate stainless steel mounting plate

Dual Illumination Modes

Mode Light output
White LED spotlight 320,000 cd, 8° beam angle, 1,131 m maximum beam distance
IR LED spotlight 940 nm, completely covert, 8° beam angle

 

Beam distance is the range at which the beam still delivers usable light, not the range at which it can be seen. See raw lumens versus effective lumens for why candela and beam angle describe a searchlight better than a lumen figure does.

Frequently Asked Questions

At 850 nm the emitter itself produces a faint red glow, visible to anyone who happens to look directly at it. At 940 nm there is no visible signature at all. The trade is range and apparent brightness through night vision, since sensors are less sensitive at 940 nm, so 850 nm is chosen where reach matters more than concealment and 940 nm where it does not. Read more on infrared vehicle lighting.

320,000 candela on an 8° beam gives a maximum beam distance of 1,131 metres. That figure is the point at which useful light remains, not the point at which the light can be seen, which is much further. The narrow 8° angle is what produces the distance: the same output spread over a wide angle would reach a fraction as far. See beam pattern in vehicle lighting.

Hard wired, through a 7 metre harness terminating in an 8-position waterproof Molex MX-150 connector. That is a deliberate choice for vehicle installation: there is no pairing to lose, no remote battery to fail, and nothing that can be jammed or interfered with. The dash panel carries the joystick, the master power switch and the white, off, IR rotary selector.

It returns the head to a stored position with one press. In practice that is used to park the light in a stowed orientation before moving off, or to snap back to a sector of interest after searching elsewhere, without hunting for it on the joystick.

Anything running a 24 V system within the 23 V to 32 V range, with a flat surface for the stainless steel mounting plate and a route for the 7 metre harness to the dash. It is qualified to MIL-STD-461G for electromagnetic compatibility and MIL-STD-810G for shock, vibration and temperature, so it is suitable for armoured and tactical platforms as well as patrol and utility vehicles.
