Underwater strobe (or flash) lights are the key to capturing bright colours underwater, that are otherwise subdued due to the effect of water. The majority of today's strobe lights are synchronized via a fibre optic cable from the camera's on-board flash. As the name suggests, an underwater flash gives out a bright and brief burst of light that can be controlled both automatically and manually. Underwater strobes come in various sizes and power levels that you can choose from. Our most popular strobes are made by Sea & Sea and AOI.
