    Hope Vision 4 = 4400 lumens Mad

    I dont really know why but it seemed too good a chance to miss
    Bought a couple of Hope vision 4`s with out working batteries so wondered what it would be like if I converted one to 15 volts and so could run the 4 new XML U3 Leds I installed in it at the full 3 amps .
    just got it finished and waiting for nightfall to see if it is an improvement Mad yes :twisted:

    Also, that's a really fantastic looking lighthead. So a standard XML 4-up fits in there with what driver? I'm ready for a new build

    No its a bit more complex than a standard 4 up









    these pics are from an earlier one as I didnt take many of this build

    Driver is a B3Flex at the full 3 amps until I find it overheats like crazy


    The firewall is nice and thick and as space is tight I milled some away leaving the post for the B3flex



    series`d up the four leds





    new switch and connector in the back plate



    ready for the beamshots when the rain stops

    OK, that's really awesome. Too bad it's a pita to build. I wish someone would make an XML 3-up like the various XPE and XPG lightboards. I could see you (and others) making some rad 3 and 6 lights.

    No its really an easy build and there is just enough room for a b3flex without the milling
    and the Hope optic gives a nice beam with the XMLs .

    nice job troutie, I love reading your retrofit builds. That light will really surprise people when you turn it on. What was the original output, ~800lm?

    Well, I've already located one in chilly Alberta, BC. If the guy would come down about 50% on his price and ship to the USA I might have to try one.

    Beamshots

    OK its not a mega thrower but does go far enough
    beam shape is very tasty with no hotspot just a nice trail light for the bars







    Its so nice that it will be on my bars for this winter but not too sure how often full power will be needed

    Get hunting for old and busted vision 4 light heads

    I reckon if you take all trouties images and animated gif them, it would be like a scene from The Time Machine

    Troutie,
    Why not use the HBflex and a 7.2V pack? http://www.taskled.com/leds/hbflexuni3_v1.00.pdf
    On page 6 of 30, there's a table that shows 7V to drive 4 XML. Would like to be able to use the packs I have now if I end up trying one of these. Also, better to use the square or round stars? I see you had both. Did you thermal tape them to where the old LEDs were?

    Dont think there is enough room for a HBflex but worth looking at to see.

    I use the 10 mm Square XML boards as a little thinner and the fit is better though have used both you need to keep your soldering as low profile as possible to avoid fouling the optic
    20 mm boards are doable too .
    Epoxy is used to fix the leds to the posts and the optic is used to align them up.


    Not yet done the tidy up but am sure the bezel is kicking around in the mess I am home alone this weekend so will be getting the shed sorted.

    Thanks for the note on the bezel. Crossing fingers...

    I have a Hope en-route since it doesn't require machining. Thinking of all my options at the moment.
