Special NAVY/SAR versions

• Dimmable and controllable• Computer controlled• Simplified installation• NVG friendly• All special lights available

– Deceptive lighting– IR follow me lights– Blue Convoy lights– Blue strobe/flashing lights


Dimmable and controllable

• 11 step dimming

• Controlled and monitored over RS-485 network– 2 independent RS-485 line drivers internally in each light– Each light has unique address (250 addresses available)– Additional analogue toggle switch

• Self monitoring



NVIS friendly

• LEDs light emmitance on narrow spectrum

• Special white LEDs for best NVIS compatibility

• Enhanced IR signature from green sidelights to make visible

• Masthead light– Dimming to level 8 (of 10)– COLREG compatible



Simplified installation

• In principle:– 1 shared power cable– 1 shared network cable

• In reality:– Light clustered in groups– Central termination of manual override– Use both networks

• Built-in redundancy



All special lights available

• Deceptive lighting• IR follow me lights• Blue Convoy lights• Blue strobe/flashing lights

Why Lopolight?

• Improved safety at sea.• Simpler = cheaper installation on new builds.• No maintenance.• No changing light bulbs (savings between 5 to 10.000 €).

– The more vibration and wet decks you have the greater the savings

• Green (energy savings around 3.000 €).• In total Lopolight is the cheaper alternative.
