I knew nothing of this myself just a couple of weeks ago, so I'll try and summarize my selection logic but if anyone more knowledgeable finds me in error, please do jump in. I haven't even received my drivers yet, so my choice is untested.</div><div><br></div><div>Generally these drivers are either "step up" or "step down" devices, meaning that they take the battery bank voltage and adjust it upward or downward depending on the voltage required for your specific LED. Not all LEDs of the same output have the same voltage requirement, so I can't provide a standard voltage for 10K lights and you will need to look that up on your LED specs. In most cases it should be clear which of those two varieties of drive you need, so deciding whether you need a step up or a step down driver I would say is the first cut at narrowing your choices. In my case I had an odd situation, because the battery bank voltage was very close to the LED voltage, and since the battery voltage will drop under load and with discharge, I could find myself crossing the threshold from stepping down to stepping up. There are a very few drivers that can step in either direction as needed, but I did find a few. </div><div><br></div><div>To summarize then... Once narrowed down to step-up or step-down type, the next thing is to look at is voltage ranges. Each driver will have an input voltage range, which needs to cover your possible battery voltages, and it will have an output range, which needs to cover the LED spec voltage. This latter voltage is constant.</div><div><br></div><div>Then finally, there's a choice of driver current capacity. This is a measure of how much power the driver can handle without burning out. Your LED will tell you how many amps it consumes. A sub in the tropics is a hot and humid environment with minimal ventilation, so I'm inclined to pick a driver that is way over-rated to prevent it from heating up much. Bear in mind you can also drive multiple lights off one driver if their combined current is within the driver's current capacity. </div><div><br></div><div>As for dimming capacity, most drivers seem to have two pots, one for output voltage and the other for output current. These controls should allow you to dim the lights, but from what I saw they are typically small components on the board, and not something intended for manipulation by the end user on the fly. It may be you could replace a miniature trim pot with one on a cable, mounted on the face of your enclosure, but you would also need to be careful with the adjustment range. You would not want a knob that burns out your lights if you turn it a little too far. </div><div><br></div><div>Hope that helps, but realistically you might find it'll take a day or two of research to narrow things down. </div><div><br></div><div><br></div><div>Best,</div><div><br></div><div>Alec</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Mar 30, 2017 at 1:49 PM, Rick Patton via Personal_Submersibles <span dir="ltr"><<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.o<wbr>rg</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Thanks Jim and Alec,<div><br></div><div>Do i have to be concerned about matching the PWM to the specific LED array I buy as there are so many out there.

<div><br></div>
<div>I just met a guy in California that made his own underwater housing and
LED lighting system for doing video and he is using an LED board that is about
3" square. He has built a PWM for it so he can dim it down and says it's a
10,000 luman 100 watt system that runs on 32 volts.</div>
<div> I don't know what a PWM is but he said that I didn't necessarily
have to have one. I can step my thruster motor supply down from 36V but one of
my concerns is how to get rid of the heat. He didn't seem to be too
forthcoming with the system he built. I think the LED array was something like
$15 each on Amazon. How are you controlling the heat in your housings and do
you think I would need a PWM for my lite?</div>

<div dir="ltr">My lights are done, I put them on Shackleton earlier today and
they are wired through the hull with penetrators. However, the wires end
inside the hull because I'm waiting for the drives to arrive, which will be
installed inside the sub. I was able to test them with a lab type power
supply on a table top, and must say these Bridgelux leds are like a little
sun in a can, I love them. These two lights I made are 5K lumens, and I
already have 10K lumen Bridgeluxes which I bought by mistake. So I'll test
these, and probably make another set with those more powerful ones. If I do,
the 10Ks will be the forward lights and the 5Ks will be oriented out to the
sides for "peripheral vision". A dimmable driver is sounding like a good
idea, or maybe just sunglasses!

my answer is who cares if some water gets between the seals. The
important part is to keep the oil inside the motor. When the
motor starts up at the surface, there is significant centrical force
that pushes the oil out with the seal in its original
orientation. I should actually remove one of the seals and just
have one seal holding oil in, just like a submersible well pump
has. Those pumps are VERY reliable. Now having said all
this, I could be wrong ;-) Stay tuned for test
results.</span></div>

points, but I personally am not ready to give up on oil

the water out. I am confident this in addition to the

The ice is off the lake by my house, so my test lake should be open

I did a small test trying to light the WD40 on fire. It's not as
flammable as I thought it would be. I think they have improved
it's non-flammability with new formulation. It's still somewhat

<div>I just ran one of my motors filled with the WD40. It seemed
to be very happy. I mainly just did it to clean the carbon build
up out of the motor. I was surprised how sealed the motor
was, it is open at one end where it mates to the gear
box. I was able to fill it up without it leaking out
anywhere. That could be an issue later when I want the mineral
oil to fill all the voids. I might need to actually drill
some holes to get some circulation . </div>
