I bought two,<BR>one of which did not work due to a faulty connection at the<BR>endcap (which acts like a switch). The factory shipped me a<BR>new end-cap that fixed the problem. In fresh water they<BR>worked well, but when I went to Islamorada last year they<BR>lasted less than a day in the salt water. After just hours,<BR>one stopped working altogether and both lights were very<BR>visibly corroded. Silly me, I hadn't thought this<BR>through. The Trustfire lights close the circuit when you<BR>screw in the endcap on the handle. They use the light body<BR>itself as a conductor, like a car uses its chassis. I think<BR>the issue is that if you put two such lights in salt water,<BR>you will get stray currents between them. <BR><BR><BR>On next week's dive I'll be testing new lights,<BR>which are LED flood lights intended for tractors or off road<BR>vehicles. I've been really impressed with how solid<BR>these are. They are wired with two cables, rather than using<BR>the light body as a ground. Second, they have a little screw<BR>that serves no visible purpose, but which when removed<BR>allows you to fill them with mineral oil. It took a while to<BR>get the last bubbles out, but with patience you can fill<BR>these with oil and remove all bubbles in about an hour. The<BR>front plastic has a little give to absorb the compression if<BR>I have any bubbles left, but I think I have none. To fill<BR>them I used a syringe with a "dispenser needle"<BR>which is a blunt syringe needle you use for filling things<BR>rather than giving someone an injection. The lights are<BR>IP67, so supposedly water-tight, but my only mod was to<BR>reinforce the cable gland with some epoxy. We shall see how<BR>they work, but my hopes are up, I think these might finally<BR>be the ideal sub lights and can be used virtually off the<BR>shelf. I recommend not buying them until Snoopy returns from<BR>next week's dive, but here is the link if you want to<BR>take a look in the meantime.<BR><BR><BR><BR><BR><a href="http://www.surpluscenter.com/Electrical/Lights/DC-Mobile-Equipment-Lights/12-24-VDC-3120-LUMEN-16-LED-UTILITY-FLOOD-LIGHT-12-999-B.axd">http://www.surpluscenter.com/Electrical/Lights/DC-Mobile-Equipment-Lights/12-24-VDC-3120-LUMEN-16-LED-UTILITY-FLOOD-LIGHT-12-999-B.axd</a><BR><BR><BR><BR><BR><BR><BR>Best,<BR><BR>Alec<BR> <BR><BR><BR><BR><BR><BR>On Tue, May 13, 2014 at<BR>7:56 AM, swaters via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>><BR>wrote:<BR><BR><BR><BR><BR><BR>Thanks Alan,<BR>I have been searching too for some kind of easy and<BR>cheap solution.<BR><BR>Thanks,<BR>Scott Waters<BR><BR><BR><BR><BR><BR><BR><BR><BR><BR>Sent from my U.S.<BR>Cellular© Smartphone<BR><BR><BR>Alan James via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>><BR>wrote:<BR><BR><BR><BR><BR><BR>Hi James,<BR>I<BR>bought 4 dive lights off deal extreme, but not a trustfire.<BR>This was in addition<BR><BR><BR>to<BR>4 x 900 lumen torches I had bought previously.<BR><BR><BR>To<BR>date I have found them unreliable, mainly in the switching<BR>function.
