[Closed] Hope Vision 4 upgrade to XMLs

not managed to hit 4000 Lumens yet? 😉

OOhh interesting..

would this be an upgrade you offer to others? (if so how much)

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 www.taskled.com

Cool. Are you going to offer this conversion in the same way you have for the Hope Vision 2?

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!

Very interested trout

Me too. Ok to send you my Vision 4 for conversion?

Nice - I'm interested too.

Might be a dumb question but how do run-times compare before and after the XML upgrade?

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.

Any idea on cost?

Depending on how much, I would be a possible for the New Year.

Good point re postage, Chris. I'll mail you after Christmas and arrange it.
Cheers Ian.
Leku, l think we're looking at about £85

£85 i'm in , any idea on run time

*registers interest*

Also interested

Me too

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

Hi Trout, did you get my reply to your reply to my email :D? No hurry just checking as I know you've have email issues recently.

Ta

That depends who you are Nixie
have you just paid for a light?

No not paid for anything yet.

😀 sorry forget about that. Was from nixie_me at hotmail d o t com re hope connectors and vision 2 upgrade.

Found it Nixie and replied

😀 thank you.

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! 😉

Troutie, how much can you supply XML leds for?

£7 each plus postage

Cool, I'll take four, what will postage be? Is paypal 'gift' OK for you to email in profile?

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!

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!

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 me
http://singletrackworld.com/forum/topic/hope-vision-2-is-upgradable

For those that are interested, Trout has upgraded my R4 as well.

It needed doing because my Trouted Vision 2 had quite literally put it in the shade!!

Can an Exposure Enduro be modded? mine is starting to look a but under powered compared with some of the newer lights.

Excuse my ignorance but would a user carry on with the original Hope batteries or would replacements be required? I 'assume' the batteries would drain quicker?

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.

I have not been inside an enduro but have done a joystick and had a look in a Maxx they are not the easiest lights to make brighter .

CB
Nixie has nailed it there I have had a couple of V2 users suddenly find their battery is old and not up to the extra current drain of max but so far no reported huge loss of runtime .

cb, depends how old your batteries are. I had my Vision 4 converted and it didn't last long when using the hi for just fast/dh sections, but my battery is about 5 years old! Chris recommended getting a Smudge battery, as they're cheaper than Hope,although that depends if you need to buy a new charger from Smudge,as not sure if he can supply bat with Hope connector. The light is brilliant now BTW. 2000lms 🙂
Will do a report when I get a new battery.

uhmmm, batteries are old but less 'used' than they should be due to my inertia in getting out of the house on cold winter nights...maybe worth a go.
