Advanced LED lights provide more output than older LEDs, while still reducing power consumption by 90% compared to incandescent or halogen bulbs. That's a huge power savings that can be critical when offshore or off the grid. The fully epoxy coated electronics are waterproof (IP65) and extremely vibration resistant, holding up to the harshest environments. Polished brass models are actually TiN (Titanium Nitride) coated, giving the look of brass, yet will never tarnish and is almost impossible to scratch. When you need the best in LED lighting, look no further than Advanced LED.
