    Bye bye 808s...hello Duo/Xera!

    Well…while the Chinese lights are fun to collect/tinker with, I decided that it was time to upgrade my primary lights for racing etc. to something a bit better than my tired-and-true but aging MS 808 P7s. Went with Gemini Duo (bar) and Xera (helmet) lightheads from Jim at Action. I will continue to use my GeoManGear 4-cell batteries with these as they seem to work just fine; I can replace them later when they die/stop working well with the MS 5600mAh batteries that he sells. I am selling off of my 808 lightheads and my SSX3 set (just won’t use this)..this should pay back 50% of the cost of the new light heads. I am keeping my Yinding (good version) and SSX2 cheap-o’s as a backup set/for my kids/loaner; I really think this is a killer budg-o set up but the color difference (bluish white from the SSX2 vs. warmer from the Yinding) bugs me and I’m not confident enough in them that I want to run them in a race situation…fine for normal riding. Finally…I picked up a Gemini and a Gloworm travel case from Action…they are really cool little cases (especially for $4)! The Gloworm one is small and works for a set of lightheads. The Gemini one is larger and works for your batteries etc. He appears to be out of the Gemini ones but he still has some of the Gloworm ones…pick em’ up! I will post up some thoughts on the next ones when I get a ride in on them next week.

    Having had the P-7 808 and now setting my wife up with the Duo/Xera,, you are in for a pleasant upgrade TiGeo. We are using one 4-cell Gemini battery and one GeoManGear battery. Keep in mind the led display on the lamp head may be a little inaccurate vs the Gemini battery, at least that is something I remember noticing when I first used the Gemini lamp head. No big deal for us though. Enjoy your new toy and give us an update after a good ride. Cheers!!

    Congrats on your new light setup! I own older versions of what you got and they've been very reliable well performing units. You're gong to love being able to adjust the power level of each light step to your needs. I look forward to hearing what you think of your purchase.

    The LED indicators on the 808s didn't work that well with the GMG batteries anyway..no biggie.

    At first this seemed silly....you only need one setting...high! But I may be able to dim them a bit wit no negative effect to get more battery life so I think I will enjoy it.

    TiGeo, I look forward to seeing how much you like the Xera and how it compares to the other lamps you own.

    When it comes to helmet lamps having one that allows for "stepless" adjustment can be nice. This way if you want you can set the output of the medium and low modes to an output that best suits your needs.

    Been a while since I've looked at the Gemini lamps, does the Xera come in an XM-L2 U2 version yet?

    Yes...they have the updated XM-L2 LEDs.

    Came today. The Duo..well...its just like the Yinding...no surprises there. The light is more white however..my Yinding has more of a "peach" colored light if that makes sense..much warmer looking. I like that the Duo doesn't cycle through off...wish it started on high like my 808s but I can program it so I will have to mess with that feature. Looks a little higher quality which would be expected. The Xera is really cool...very tiny..much smaller/lighter than my 808. I like the no-edge effect of the optics vs. reflector...should make a great combo! Hopefully can ride them this week and try them out.

    The programming is actually pretty cool. I was able to change the flow to high/med/low and then the setting for each to 100%/90%/50%..pretty neat and if I can handle less than 100% as my "high" then I can get more out of my batteries.

    Quick night ride indicates these are the badass lightweight setup. The Xera is so light...nice on the helmet and almost unnoticeable. Perfect helmet light...may try the spot optic next time. The Duo is just like the Yinding....great bar light. I really like that both have the same color...easier on my eyes.

    Legit night ride (10 miles)..these are outstanding. I still need to swap to the spot optic on the Xera. 2 hours of runtime and the light just turned organ on the lights as I got to the car (4-cell Geoman batteries). Great set up and v. light. 18 hour race next weekend!
