With less than 1.5W of consumption, NaviLED®360 lamps draw a fraction of the energy required to run a conventional 2 nautical mile incandescent lamp. Robust fixed pole mount with two counter-sunk holes. No bulbs, No maintenance. Ultra long service life Hella marine LED technology has no filaments to break making NaviLED® lamps extremely shock and vibration proof for reliability and safety in demanding conditions. MultivoltTM 9-33V DC Advanced electronics ensure reliable illumination and lamp protection even under severe voltage fluctuations and low battery voltages. Sealed within the base or aluminium pole, the compact MultivoltTM drive circuitry provides reverse polarity, spike and over-voltage protection for long life and reliable operation. Safe and highly visible Hella marine optics deliver 100% correct light output and enhance visibility compared to bulb navigation lamps.
