An array of 60 high contrast SMD light emitting diodes (LED) with a light emission angle of 120 degrees for each LED and a minimum light intensity of 100 Candela. The LEDs are arranged in 10 independent circuits so the loss of one led will not stop the light from functioning.

Environmental Parameters
  • -40 to 70 degrees Celsius.
  • 0-90% RH non-condensing.
Connection Details
  • Terminal 1: 110VDC active supply (flying lead marked with red heat sink)
  • Terminal 2: 0VDC supply (flying lead unmarked)
  • Terminal 3:Ground supply (flying lead marked green/yellow)
  • Wiring is accomplished using Huber & Suhner 4GKW-AX-1.5mm2
Power Supply
  • 55VDC to 154VDC. Other voltages on request
  • Current consumption is 60mA @ 110VDC
  • Inrush current of 200mA for 80 micro seconds. The LED current is controlled by a closed loop feedback circuit. This ensures constant brightness independent of power supply voltage
  • The power supply to the light is protected by a power conditioning circuit which includes voltage spike removal to ensure compliancy with EN50121.
  • Reverse polarity protection (reverse connection will not cause any damage).
Material of manufacture
  • Housing is metal spun 1.5mm aluminium bright clear anodised.
  • Window is 2mm Makrolon polycarbonate
  • The light is sealed with Sika Firesil Marine N
  • All srews are 304 grade stainless steel
  • Cable entry grommet is sealed with Sika Firesil Marine N
  • LEDAWS is 200grams.
Mounting Details

Surface mounting bright clear anodised aluminium enclosure of case dimensions 110mm diameter flange by 87mm deep, with mounting achieved by 3 of 7mm holes 8.00mm in from the rear edge of the housing.
