We can do flat.

I to like the idea of a flat housing that can be either mounted flat to a FRP shell or the mounted into a recess molded into the FRP.

I'm interested in collaborating on this, and can offer to machine propotype housings. In particular, I'm interested in LED lights with a housing format as flat as possible - "surface mount" lights if you will, that could be mounted directly on the body of the sub without sticking out excessively. There are tons of off-the-shelf lights out there that can easily be oil filled and work just fine, but I have not found any flat ones yet. 

Best,

Alec

Ken, I have been off the list for some time due to work and due to my email service not passing through psub emails.  I had to go to a gmail email account to get back in the loop.

I am in on your suggestion to build LED psub light based on the Bridgelux Varo 29 (BXRC-50C 10K0-L-24) .   I can help on the housing design and I have access to a machine shop to fabricate the housing. I also have test chamber we can use to qualify the prototype.  Maybe we could pick one of the DeepSea Power and light LEDs take its specifications and tweak to fit a typical psubs application.  

We would probably need to set up something like Dropbox location, accessible to all that want to participate in the design, fabrication and testing to keep from swamping the PSUB  list.

I have a function LED subsea light that works fine but would like more lumens.  It is a 5000 lumen light but would like a 10,000 lumen light.

My suggestion is for you take the point since you came up with idea.  Maybe we could canvas the site and see would be interested in working on the project as a first step.  Given your background in EE, maybe you could come up with a first pass at the specification and we can comment on it.
