One of Princeton Tec's most popular light, the Shockwave II Halogen Primary Light features two power settings which can be changed with the flip of switch.  The economical 7.5 watt power mode burns for up to 10 hours and provides plenty of light for most diving conditions.  For those pitch black nights, wreck diving and dark crevices, simply flip the switch to the screaming bright 15 watt output mode.  Princeton Tec's innovative dual filament, multi-output bulb system eliminates the need for two bulbs and complex switching systems
