  <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>

    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

          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>

        <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>
