Out of the water it hit 120F (49C) in 7</div><div>minutes. The LED has a maximum temperature rating of 60C so was keeping</div><div>back a bit from that. </div><div>I dropped the current down & ran it out of the water at 33W & 25W but it climbed </div><div>to 125F in 20 minutes for 33W & 15 minutes for the 25W.</div><div>I am using a cast acrylic 8mm thick lens, & this didn't get hot either in air</div><div>or water. Using acrylic instead of glass is saving me $90-.</div><div>Am making a few minor housing design adjustments for the final iteration.</div><div>Have also ordered a dozen of these 50 V 350 mA constant current regulator &</div><div>LED drivers. </div><div><br></div><div><a href="http://www.onsemi.com/PowerSolutions/product.do?id=NSI50350AD">http://www.onsemi.com/PowerSolutions/product.do?id=NSI50350AD</a></div><div>They are TINY; about 1/4" square & you run them in series to get the desired</div><div>amperage. They have a wide input voltage & would be great for a 36V system.</div><div>Alan</div><div><br><br><div>Sent from my iPad</div></div>
