<span style="font-family:Verdana; color:#000000; font-size:10pt;"><div>Before I oil compensated my 10,000 lumen LED head light, I messed around with epoxy potting. I had two problems. One is the epoxy yellowed over extended time of use as most resins and plastics do. The other is with a LED this powerful, it does give off heat and the epoxy acted as a insulator instead of a conductor. This resulted in the LED starting to burn inside the potting. Two corrections for this would be to experiment with different epoxies and / or not use such a powerful LED array as what I am using. I like my lights bright :)</div>

I met an engineer from Ontario, I showed him my killer light and he said "why don't you pot the whole thing instead of oil filling" Hmmm I had no response, he also said they have potted LED's for use in chemical environments. I use a crystal clear casting resin for making electrical penetrators. Might be worth a try.<br />Hank<br />_______________________________________________<br />Personal_Submersibles mailing list<br /><a
