[PSUBS-MAILIST] LED Lights

[Alan James via Personal_Submersibles]

Thanks Dude,with regard to the cost; there are a number of lights on Deal Extremefor around $15-, that may have suitable housings. One I have looks like it will only require an O-ring grove as an upgrade. Keep the housing & throw the rest away. IP67 Waterproof 10W 700lm 6500K White Light LED Spotlight / Underwater Lamp - Silver

They are generally threaded at the back & have something similar to a blue globecable gland in them. Just replace this gland with a blue globe if the thread iscompatible. Once we have the final led & driver dimentions, I will have a look.No reason why we couldn't do a few variants of housings using the same led & driver.Alan

My three words of advice...cost, cost, cost.

One measure of a success for this project will be how many people 
actually build/use it.  If it costs more to manufacture than just 
purchasing something like 
http://www.surpluscenter.com/Electrical/Lights/DC-Mobile-Equipment-Lights/12-24-VDC-3120-LUMEN-16-LED-UTILITY-FLOOD-LIGHT-12-999-B.axd 
off the shelf then it's real world application by psubbers may be limited.

Over-spec'ing the design above requirements for typical recreational 
operations (ie 10,000 psi capability) is likely going to drive up the 
cost.  Also, let's remember that "cheap", "low cost", and "good price" 
are relative terms for a diverse group like PSUBS so include realistic 
estimates of parts and manufacturing especially if tooling is required.
