Hope Vision 4 upgrade to XMLs
No doubt you’ll post more details of the conversion either here or on MTBR. In the meantime any idea what optics are in use in the Hope Vision 4? It says on their website that there are 3 spot (+/-5 deg) and one flood (+/- 15 deg).
Also the original battery is a 7.4V 5200 mAh job so either the original LEDs are wired 2S2P or it is using a boost driver. How you have wired the XM-Ls and what driver are you using?Posted 6 years ago
No idea what the optic is it is a custom job for hope so the website will be correct .
I have used the hope optic it does give a floodier beam as the photos show .
I believe it is a boost driver but did not check it out as was scrapping the driver anyways .
I have wired the leds 2s2p and am using an Lflex driver from http://www.taskled.comPosted 6 years agozacgillbanksMember
I’d just like to give a shout of thanks to Troutie for XML’ing my HopePosted 6 years ago
Vision 4 lights. They’ve gone from 960 lumens to around 2000 on max!!!
I’ve only had the chance to try them out once but the light level and
spread is fantastic, far superior to how they were before hand. Cheers
Troutie – highly recommended!
Only done the one for Zac above so maybe he can report on it please
just finished another one today I cant do runtime experiment as only have the light head and no battery .
what you get is approx 2000 lumens on full you still have three levels of output and a strobe mode
on full it will pull 3.5 amps from the battery so you should be able to workout the approx runtime from your battery specs .
medium pulls around 1.5 ampsPosted 6 years agozacgillbanksMember
Regarding the burn times, I’ve ridden my Trouted Hope 4 about 7 or 8 times now. I normally ride for about an hour or so and the battery hasn’t needed to be recharged yet.
I normally vary the light between flashing, low and medium – only occasionally having it on full power. So I don’t have any specific burn time figures – sorry.
I can say the light is bloody brilliant now off road and with it flashing at 2000 lumens certainly gets you noticed in traffic!Posted 6 years ago
Kind of an old thread to bring back to life (sorry).
Has anyone got any pics of the inside of the hope vision 4?
I’m considering this upgrade, but notice that trout mentioned that the one he had upgraded was sent to him as the owner pulled the domes off the standard LEDs while removing the optic. I’m quite happy with the electronics involved, and a little bit of small scale fabrication but I dont want to take the optic off mine and decide I can’t do the upgrade DIY style and end up with a useless light!
Trout, if you’re about, do you remember what size stars the standard leds were on? were they on 4 separate stars or a single star with 4 emitters on?
Any tips would be appreciated!Posted 5 years ago
next time I get a vision 4 in I will take some photos and do a how to mod the beast .
but at the moment it seems to be vision 2 s that are dropping through the letterbox
the bezel on the hope 4 Can be rra right Git to remove first a spray with penetrating oil helps
and some marigolds to aid grip .
the oring under the bezel sticks to the optic a d twists it round breaking the legs and removing the led domes this is not too much of a problem as the upgrade replaces the LEDs and driver but does make locating the optic a hastle
vision two thread is here for those who have emailed mePosted 5 years ago
cb, uses the original batteries. The drain question is a bit more difficult. The newer leds may be more efficient so use less power per lmn, however they might also be running at a higher power level so use more. Then again as the lower power levels now output more light and the leds run more efficiently on these settings you may find you get better run time as you only need to use medium most of the time, with hi only for downhill sections.Posted 5 years ago
