This is a quick test to confirm whether or not this driver would survive or even run with the voltage above spec. To my surprise the driver did run and after a 5 minute workout the light was still shining brightly and there was not a hint off smoke coming from the driver though it was hot. The above results were taken after thirty seconds off operation. I do not recommend using this driver with any voltage higher than spec, but I may.<img src=" HTML http://budgetlightforum.com/sites/all/libraries/tinymce/jscripts/tiny_mce/plugins/emotions/img/smiley-wink.gif"<br />alt="Wink" title="Wink" border="0" /></p><p> </p><p>The usual XM-L LED was used for the testing.</p><p>Other drivers tested for comparison are,</p><p><a href=" HTML http://budgetlightforum.com/node/13488#node-13488">http://budgetlightforum.com/node/13488#node-13488</a></p><p><a<br />href=" HTML http://budgetlightforum.com/node/15649#node-15649">http://budgetlightforum.com/node/15649#node-15649</a></p><p><a<br />href=" HTML http://budgetlightforum.com/node/15739#node-15739">http://budgetlightforum.com/node/15739#node-15739</a></p><p><a<br />href=" HTML http://budgetlightforum.com/node/21622">http://budgetlightforum.com/node/21622</a></p><p><br /></p><p>Some comparison night shots.</p><p>Firstly the AA Enelo op at .37 amps to the led.</p><p><img src=" HTML http://i1074.photobucket.com/albums/w415/mrsdnf/FT%20SM%209-3%206v%20SKU1127402/Eneloop.jpg"<br />width="800" height="600" /></p><p>AA LlFePO4 at 07 amps to the led.</p><p><img src=" HTML http://i1074.photobucket.com/albums/w415/mrsdnf/FT%20SM%209-3%206v%20SKU1127402/LIFePO4.jpg"<br />width="800" height="600" /></p><p>18650 LiIon at 1.75 amps to the led.</p><p><img src=" HTML http://i1074.photobucket.com/albums/w415/mrsdnf/FT%20SM%209-3%206v%20SKU1127402/18650.jpg"<br />width="800" height="600" /></p><p>This driver was set up in a $4.00 501B P60 host. The XP-G2 led was dedomed. It was originally a cool <span style="font-size: 1em;">white tint. When dedomed the tint changed to a slightly warm color on the Eneloop and more off a neutral </span><span style="font-size: 1em;">tint with the higher current fed from the 18650. </span></p><p><span style="font-size: 1em;">The last couple off shots were of the battery adaptor made for the AA size lights. It is some sort of black teflon with a 1/4 round copper pin peened over on both ends for battery contact. It was intentionally made short incase any batteries got stuck inside.</span></p><p><span style="font-size: 1em;"><img src=" HTML http://i1074.photobucket.com/albums/w415/mrsdnf/FT%20SM%209-3%206v%20SKU1127402/P1130763.jpg"<br />width="800" height="432" /></span></p><p><span style="font-siz e: 1em;"><img src=" HTML http://i1074.photobucket.com/albums/w415/mrsdnf/FT%20SM%209-3%206v%20SKU1127402/P1130767.jpg"<br />width="800" height="607" /></span></p>[/html] *****************************************************
