the light is operational and has not flooded. If it gets
flooded, upon surfacing, the light can become internally  pressurized, which may be potentially dangerous.
Additionally, if the power remains on when the light has
partially flooded, it is possible for electrolytic generation
of an explosive mixture of hydrogen and oxygen gases.
If a light appears flooded upon removal from the water,
it should be treated as potentially dangerous. Point the
light away from persons and valuable equipment and
make sure that the power is disconnected. See the
Flooded Light Repair procedure for more information.<span><br clear="none"></span></div><div dir="ltr" id="yiv9775660070yui_3_16_0_1_1437645894487_3016">Flooded Light Repair
If the light stops working while underwater, you should
assume that it has been flooded. When working on a
potentially flooded light, it is important to use appropriate
personal protective equipment to include, at a minimum,
eye and hand protection.
1. Place the light face down on a table making sure
that the connector side is facing up.
2. Unscrew the End-Cap Retainer with a spanner
wrench.
3. Slowly depressurize the connector compartment
and remove the end-cap with the connector
attached to it.
4. Without removing the circuit board, rinse the
compartment with clean fresh water.
5. Bake the light in a warm oven at no more than
100° C or 212° F for at least 30 minutes to bake
out any moisture that may be present.
6. If it is determined that the flooding occurred
due to damage to the connector, please see the
Changing the Connector section below.
7. Once it is determined that the light is not or no
longer internally pressurized, and the flooding
was not due to the connector; it is recommended
that the light be returned with the End-Cap
Retainer partly unscrewed as in step 2 above, to
DeepSea Power & Light for evaluation and repair
using the RMA Procedure for Repair below. </div>  <div id="yiv9775660070yui_3_16_0_1_1437645894487_2877" style="font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:16px;"> <div id="yiv9775660070yui_3_16_0_1_1437645894487_2876" style="font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:16px;"> <div class="qtdSeparateBR"><br><br></div><div class="yiv9775660070yqt6525433205" id="yiv9775660070yqt83958"><div dir="ltr" id="yiv9775660070yui_3_16_0_1_1437645894487_2875"> <hr id="yiv9775660070yui_3_16_0_1_1437645894487_2874" size="1">  <font id="yiv9775660070yui_3_16_0_1_1437645894487_2878" size="2" face="Arial"> <b><span style="font-weight:bold;">From:</span></b> Alan James via Personal_Submersibles <personal_submersibles@psubs.org><br clear="none"> <b><span style="font-weight:bold;">To:</span></b> Personal Submersibles General Discussion <personal_submersibles@psubs.org> <br clear="none"> <b><span style="font-weight:bold;">Sent:</span></b> Thursday, July 23, 2015 5:17 PM<br clear="none"> <b><span style="font-weight:bold;">Subject:</span></b> Re: [PSUBS-MAILIST] LED Lights<br clear="none"> </font> </div> <div class="yiv9775660070y_msg_container" id="yiv9775660070yui_3_16_0_1_1437645894487_2917"><br clear="none"><div id="yiv9775660070"><div id="yiv9775660070yui_3_16_0_1_1437645894487_2919"><div id="yiv9775660070yui_3_16_0_1_1437645894487_2918" style="color:#000;background-color:#fff;font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:16px;"><div id="yiv9775660070yui_3_16_0_1_1437621043751_7789"><span id="yiv9775660070yui_3_16_0_1_1437621043751_7826">Thanks Dude,</span></div><div id="yiv9775660070yui_3_16_0_1_1437621043751_7790"><span id="yiv9775660070yui_3_16_0_1_1437621043751_7807">with regard to the cost; there are a number of lights on Deal Extreme</span></div><div dir="ltr" id="yiv9775660070yui_3_16_0_1_1437621043751_7790"><span id="yiv9775660070yui_3_16_0_1_1437621043751_7877">for around $15-, that may have suitable housings. One I have looks like it will only </span></div><div dir="ltr" id="yiv9775660070yui_3_16_0_1_1437621043751_7790"><span id="yiv9775660070yui_3_16_0_1_1437621043751_8120">require an O-ring grove </span>as an upgrade. Keep the housing & throw the rest away. </div><div dir="ltr" id="yiv9775660070yui_3_16_0_1_1437621043751_7790"><a rel="nofollow" shape="rect" id="yiv9775660070yui_3_16_0_1_1437621043751_8167" target="_blank" href="http://www.dx.com/p/ip67-waterproof-10w-700lm-6500k-white-light-led-spotlight-underwater-lamp-silver-216504#.VbB4urOqpBc">IP67 Waterproof 10W 700lm 6500K White Light LED Spotlight / Underwater Lamp - Silver</a><br clear="none"></div><div class="yiv9775660070link-enhancr-attachment yiv9775660070link-enhancr-element yiv9775660070richcompose-card" id="yiv9775660070enhancrCard_0" style="width:450px;font-family:'Georgia', 'Times', 'Times New Roman', 'serif';margin-top:5px;margin-bottom:5px;background-color:#ffffff;"><table class="yiv9775660070link-enhancr-element" id="yiv9775660070yui_3_16_0_1_1437621043751_8209" cellspacing="0" cellpadding="0" border="0" style="width:450px;height:170px;display:block;"><tbody id="yiv9775660070yui_3_16_0_1_1437621043751_8208"><tr class="yiv9775660070link-enhancr-element"><td colspan="8" rowspan="1" class="yiv9775660070link-enhancr-element" style="height:1px;background-color:#e5e5e5;font-size:1px;border-collapse:collapse;"><div class="yiv9775660070link-enhancr-element" style="height:1px;background-color:#e5e5e5;font-size:1px;line-height:0px;"> </div></td></tr><tr class="yiv9775660070link-enhancr-element" id="yiv9775660070yui_3_16_0_1_1437621043751_8212"><td colspan="1" rowspan="5" class="yiv9775660070link-enhancr-element" style="width:1px;background-color:#e5e5e5;font-size:1pt;border-collapse:collapse;"><div class="yiv9775660070link-enhancr-element" style="width:1px;background-color:#e5e5e5;font-size:1pt;"> </div></td><td colspan="1" rowspan="5" class="yiv9775660070link-enhancr-element yiv9775660070link-enhancr-image-wrap" id="yiv9775660070yui_3_16_0_1_1437645894487_2954" style="vertical-align:middle;width:168px;height:168px;background-color:#000000;border-collapse:collapse;"><div align="center" class="yiv9775660070link-enhancr-element" id="yiv9775660070yui_3_16_0_1_1437645894487_2953" style="width:168px;"><a rel="nofollow" shape="rect" class="yiv9775660070link-enhancr-card-urlWrapper yiv9775660070link-enhancr-element" id="yiv9775660070yui_3_16_0_1_1437645894487_2952" target="_blank" href="http://www.dx.com/p/ip67-waterproof-10w-700lm-6500k-white-light-led-spotlight-underwater-lamp-silver-216504#.VbB4urOqpBc" style="text-decoration:none;color:#000000;"><img class="yiv9775660070link-enhancr-thumbnail-image yiv9775660070link-enhancr-element yiv9775660070yahoo-ignore-inline-image" id="yiv9775660070yui_3_16_0_1_1437645894487_2951" alt="image" width="168" height="168" style="display:block;margin:auto;" data-id="f08
