TRON ML-100 LED Marking Light


High Intensity LED Marking Light

  • Ideal for fish farms and other floating or submersible objects.
  • Programmable intensity, flash rate, synchronization and daylight switch.
  • Powered by 3 Alkaline D-Size battery cells, total of 4.5 VDC.

From Jotron

This product is part of the Tron ML series from Jotron.  The product range can be used for marking fish farms, fishing equipment, buoys, seismic cables, anchor chains and moorings, oil cables, and offshore installations.

  • The Tron ML-series has high intensity LEDs with several enhanced features implemented. They can be activated through programming of :
  • Light-intensity.
  • Flash-rate.
  • Synchronization (and master/slave).
  • Daylight switch (with adjustable ambient light level for ON/OFF).

Tron ML-series

For marking of fishing equipment such as nets and long line equipment, buoys, seismic cables, anchor chains and moorings, fish farms, oil cables and offshore installations.

  • Tron ML-100 is powered by 3 Alkaline D-sized battery cells, total of 4.5 VDC.
  • Tron ML-200 is powered by a special high capacity battery pack at 4.5 VDC.
  • Tron ML-300 uses external 10-27 VDC.

The Tron ML-series has a module-based construction, making them user-friendly during any service and repair.
The Tron ML-series replaces the previous MF-marking light series from Jotron.

Tron ML-100 is mechanical identical with previous marking lights MF-1111 LED, MF-1112 and MF-1111B powered by 3 Alkaline D-sized battery cells.

Tron ML-200, based on the Tron ML-series El-unit in combination with the aluminum tube from previous MF1114 series, is the new long-life operation 4.5 VDC marking light.

Tron ML-300 will replace the previous MF-1117, 1118 and 1119 – and has the same mechanical “foot-print”.

Tron ML-El unit, 4.5 VDC and 10-27 VDC The Tron ML-series El-unit is used in all the Tron ML-series of marking lights with different programming.

Tron ML-Master
Syncronization master for use with the Tron ML-series.

Syncronization master current drain @ 4.5 VDC = 20 mA.
Expected operation with ML-100 battery 3 x 1.5 VDC D-sized battery cells = 32 days.
Expected operation with ML-200 battery-pack (X-91585) = 225 days.
