The Neptune Tackle LED Underwater Light has many advantages over standard 12 Volt lights. LED lights don't require a separate 12 volt battery and wiring, plus LED lights generate low heat and can be used out of the water and then placed back into the water without the gear of the glass cracking.
LED underwater lights are the simplest and easiest to use, just insert the batteries and away you go.
Note: The pole length is approx 800mm and the batteries are placed into the handle of the pole. The batteries are also included.
