Been a while looking at this Hope 4 but finally done it
managed to slot 4 XMLs in it and a new driver so here are the first results I am not sure what the Hope battery can deliver so am only driving the leds at 1.5 amps so approx 2200 lumins .

OOhh interesting..
would this be an upgrade you offer to others? (if so how much)
Posted 6 months ago # -
I was going to ask about the Vision 4 lights to see if they were worth the money, but looking at the photo's, they look great. By the way, what is XML, new LED bulbs or something?

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?

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.com

Cool. Are you going to offer this conversion in the same way you have for the Hope Vision 2?
Posted 6 months ago # -
Could the conversion be used with a bigger battery to make it even brighter?

I'd just like to give a shout of thanks to Troutie for XML'ing my Hope
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!Posted 5 months ago # -
Very interested trout
Posted 5 months ago # -
Me too. Ok to send you my Vision 4 for conversion?
Posted 5 months ago # -
Nice - I'm interested too.
Might be a dumb question but how do run-times compare before and after the XML upgrade?
Posted 5 months ago # -
Might have to wait till after christmas as buried under a mountain of vision 2s at the moment
also post gets a bit iffy for losing parcels at this time .

Very Very interested, as I live round the corner from Zac I think I'll be popping in to do a comparison.

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 amps

Trout,
Do you reckon this upgrade is DIY-able like the vision 2?
I'm handy with a soldering iron but can't do any machining of the lamp housing if thats required.
Also, if its not DIY-able, what timescale are you looking at at the moment for the conversion?
Cheers.

Troutie - be in touch soon - just waiting for further input but nearly there now!
Posted 4 months ago # -
Troutie, how much can you supply XML leds for?
Posted 4 months ago # -
£7 each plus postage
Posted 4 months ago # -
Cool, I'll take four, what will postage be? Is paypal 'gift' OK for you to email in profile?
Posted 4 months ago # -
hi trout did you get my email about the maxx d and joystick?

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!
