[PSUBS-MAILIST] LED Lights

The electronics and custom PWB won’t be the issue. Figuring out what we want may be the biggest problem.

Alan, we have a lot of collective experience we could use on the project.  I really love the fact that Ken is an EE with experience LED drivers.  After we agree on specs and packaging I am sure he can design a custom PCB for the electronics.  Having just gone through the exercise of designing a 1-arm housing, I don't think it will be difficult to design the housing.

Cliff,

I'm on board with the LED light project.

Have done a bit of experimentation & bought about 10 different LED

flashlights, underwater flashlights, flood lights & various lenses.

I also have a friend whose working involves running banks of LED

lights on advertising hordings, if we get stuck on the technical side.

Alan

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.

Cliff
