In any case, I am still waiting for the optics to arrive. Should be any day soon. <BR/>I'll post beam shots as soon as I get them.Joehttps://www.blogger.com/profile/10839083466845249685noreply@blogger.comtag:blogger.com,1999:blog-38883835.post-12896509022854762482007-02-28T11:07:00.000-08:002007-02-28T11:07:00.000-08:00Hi Joe,The optic that you said here,can it fit the...Hi Joe,<BR/>The optic that you said here,can it fit the Elly head with the Cree attached?If it fit than i'm gonna order one optic myself:)Anonymoushttps://www.blogger.com/profile/17517282302710449779noreply@blogger.comtag:blogger.com,1999:blog-38883835.post-53741814442128569142007-02-22T16:31:00.000-08:002007-02-22T16:31:00.000-08:00The spread can be changed by removing the reflecto...The spread can be changed by removing the reflector and putting in a different optic.<BR/>Something like this: <A HREF="http://cgi.ebay.com.au/15-degree-lens-for-Luxeon-LEDs-Black_W0QQitemZ8066535595QQihZ019QQcategoryZ33713QQtcZphotoQQcmdZViewItem" REL="nofollow">http://cgi.ebay.com.au/15-degree-lens-for-Luxeon-LEDs-Black_W0QQitemZ8066535595QQihZ019QQcategoryZ33713QQtcZphotoQQcmdZViewItem</A><BR/><BR/>The Cree in the Elly is really only driven at 1/2 it's capability. If driven at it's typical current it will produce twice as much light.<BR/><BR/>Two ways of doing this:<BR/>1) modify the driver circuit - a bit hard to do.<BR/>2) change the battery source - hard to do as we're limited to AA.<BR/><BR/>I am trying to find a 3V lithium AA battery to do this. they are hard to find and not available in Australia.<BR/>But i have heard that a CR-V3 digital camera battery is actually 2 AA's wrapped together. Few people have separated and used these.<BR/>You can buy AA Lithium's from Ebay etc but they are typically 3.7V which would fry the current circuit. Therefore these 3V AA's from a dismantled CR-V3 / RCR-V3 should do the trick.<BR/><BR/>I'll try to find one and experiment.<BR/><BR/>Another option is to just remove the AA and attach a cable to a big battery pack like on my 5W. This may also be a good option but again will require changing the driver circuit. This should be easier as the battery compartment or the battery pack can be used to house the driver as well.Joehttps://www.blogger.com/profile/10839083466845249685noreply@blogger.comtag:blogger.com,1999:blog-38883835.post-78545109557068367872007-02-22T16:16:00.000-08:002007-02-22T16:16:00.000-08:00the 5w kiks. if only the spread of the beam can be...the 5w kiks. if only the spread of the beam can be adjusted on the ellys. Not a bad output for such a small light.Vonhttps://www.blogger.com/profile/17011686061196782039noreply@blogger.com
