The Dragonfish deep-sea LED strobe light was designed by Arctic Rays, LLC for imaging applications on AUVs and other underwater vehicles or platforms.

Currently in use o AUVs such as the Remus 100, 600 and 6000, Dragonfish LED strobe lights offer compact size, high brightness (30,000 lumens at 5ms, 42,000 lumens at 200µs) and low current draw (550 mA at 24Vdc), suited for AUV-based still photography, where payload size and power budget are critical.

Drive electronics, thermal protection and intelligent microprocessor control are integral in the Dragonfish’s small 1ATM, 6,000m-rated, 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 beams are a wide 62⁰ flood, or a narrow 35⁰ spot.

The compact design weighs 318 or 420 grams in water (depending on options), and measures 70 mm in diameter and 70 mm long. Housed in a 6061-T6 AHC aluminum housing, it is available in depth ratings of 1,000 or 6,000 meters.
