Shockwave II, We couldn't think of a better name for a light that will re-define primary lighting as we know it today. A radical 8 C-cell design eliminates nearly half the size and weight of standard primary dive lights while delivering up to 15 watts of power. This light will forever change the way you view the underwater world. This is a doggone bright light and even comes with batteries!

The light has a dual filament bulb system. The economical 7.5-watt output mode burns for up to 10 hours and provides plenty of light for most diving conditions.

For those really dark nights, wreck diving and deep dark crevices, simply flip the switch to the screaming bright 15-watt output mode. All this is possible as a result of Princeton's innovative dual filament multi output bulb system that eliminates the need for two bulbs and complex switching systems. This unique system also offers the added security of switching to an alternative bulb filament in the event the filament in use burns out!

The extreme versatility and reliability of the Shockwave II is sure to satisfy your every need and be there when you need it.
