Sea & Sea LX-33 Video Light, with 33 Watt / 7.4 V Halogen Bulb, Blue

The LX-33 is designed exclusively for underwater use. The light comes with a bright 33-watt bulb and a light-intensity controller for continuous adjustment from full brightness to a low glow. Its delicate lighting adjustment matches subjects both far and near. A set of fully charged batteries in the light provides up to 100 minutes of continuous lighting.

An LED bulb in the light flashes red when the battery is low and needs recharging. The LED bulb also displays battery charging process in two steps. Because the light uses lithium-ion batteries, you don't need to fully discharge the batteries because they're not susceptible to the memory effect.
