SAIS is getting ready to launch a new series of Underwater LED lights specially designed for use in underwater broadcast video projects and for high-end prosumers.
There will be a ~2000 lumen version and a ~ 6000 lumen version. Both come with rechargeable Li-Ion battery packs that will provide more than 1 hour of continuos operation at full power and over 2 hours at half power.

I will add more technical details after the launch in mid-November.

We recently finished this camera.  It uses the Nikon D700 DSLR, a full frame (35-mm equivalent) 12.1 Megapixel camera combined with the AF-S Nikkor 24-70mm f/2.8G ED lens.  The viewport is a 8 inch glass dome with anti-reflective coating.  The body is titanium and the whole thing was designed to go more than 3 miles deep in the ocean.

The camera mounted on the internal assembly next to the housing. The SAIS developed system allows control of zoom, focus and all camera functions via a single ethernet connection to a networked computer on the surface. A live video feed of the camera view is provided and still-images are transferred to the connected computer via the single ethernet connection as soon as they are taken. The zoom is controlled via SAIS developed software and mechanical components. The housing includes a temperature, sensor and water alarm.

One of the most interesting features of the camera is that all  functions and image-transfer to the surface are conducted over a single ethernet (RJ45) connection.  All the cameras functions including aperture, shutter-speed, ISO, shutter-release, all menu functions and zoom can be controlled from a single laptop computer on the surface.  The software provides a live video feed of the camera view to the operator for framing, adjusting settings and monitoring the underwater scene where the camera is deployed.

Nominal voltage is 12VDC with a draw of ~ 5A.   I am hoping to have some images from one of the first scientific expeditions to use the camera soon.  Providing we can secure permission to post them, I will add them here soon.

Just finishing up a project that I will write more about at a later date.  This is a 6000m (19,700ft) depth-rated housing for a Nikon D700 DSLR with a 24-70mm f2.8 lens.
