Dragonfish LED Strobe Light


Dragonfish is a deep-sea LED Strobe light designed for imaging applications on underwater vehicles and instrument platforms. Its compact size, high brightness, and low current draw, make it ideal for AUV-based photography, where payload and power budget is critical. Drive electronics, thermal protection, and intelligent microprocessor control are integral in the Dragonfish’s small 1ATM anodized aluminum housing. External power and trigger are all that are needed to operate. The unit is easily synced to a standard TTL camera shutter, and will self-quench automatically when the shutter line is released, allowing user-controllable strobe durations up to 5ms. It can also be quenched by an alternate source using the independent quench line. Standard output is a wide 62⁰ beam, which can be focused to a narrow 35⁰ beam with an optional field-installable Fresnel lens.
