<div dir="ltr">Hank,<div>I fabricated an aluminum housing for my prototype using 2 1/2" sched 40 pipe with a heat resistant 1/8" thick lens and a blue globe fitting in the back and oil filled it. The 10,000 luman array is 1 1/2" square and costs $3.00 each but puts out an enormus amount of heat and is about 100 watts each and I apparently have to knock down the voltage from 36 to about 30 to 34 volts or they fry. I want to use three lights facing forward, one on each side in the middle and one light aft and so that's a lot of watts sucking off my thruster bank and am having a hard time finding a pwm to dim them and keep them from seeing 36v.</div><div>Rick</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Feb 1, 2018 at 11:33 AM, hank pronk via Personal_Submersibles <span dir="ltr"><<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div style="font-family:Helvetica Neue,Helvetica,Arial,sans-serif;font-size:13px"><div></div>
<div>Rick,</div><div>You can keep it real simple and just buy water proof lights (LED) and oil fill them. Just inspect the light to make sure you can drill and put a filler plug in. I have great luck with a 24,000 lumen light bar. I am actually buying a clear acrylic cylinder to put my light into. Alec has had luck with this also, maybe he can suggest the particular light to use.</div><div>Hank</div><div><br></div>
