May be of interest we have been developing more LED lighting systems and Camera units for both Diver and ROV work.
We are also doing a lot of educational work at present during our down time.
Here is a link.

feedback would be useful and if any one would like to test any units let me know we hope to send some more prototypes of to Ireland in June for some marine science projects.
Thanks for taking the time to look.
