[Closed] Lumicycle Halogen > LED Kit Vote

That sounds like a good idea to me. I'm very lazy, you see, and if someone else could put all the effort in it would be grand.

I'm also interested in a kit.
Not too bothered whether it includes the LEDs / optics or not, so long as someone gives a link for where to order them from.
I presume there's a range of different LEDs it will work with (ie different bins/brightness/cost), so buying them separately would give a choice of that.

Yeah, I'd be up for a kit. Not really fussed whether it includes the LED/optics to be honest, but the driver, switch, heatsink, power socket would be welcome.

I wouldn't mind converting another can the same way as I did the first but it was all a bit of a squeeze in the can so something that comes with a pretty much integrated heatsink/driver with an LED board that would fit on the front would make things a lot easier, especially if it has the off/low/high option of the original driver that I stuck in a Lumi can.

The first can i converted used the 675mA driver & the can seems to handle the heat fine (and allows stupid long run time of 14hrs+ on high), so I was intending to convert the second one using the 975mA driver to get more light out of it. Should still allow a run time with both lights on high of 5hrs or so and if heat build-up does become an issue I'd just swap the driver out for the lower current one.

Oh god, I'm rambling again. To summarise, yes I would be interested but it depends on the output of the driver. I'd rather go for something a fair bit higher than the 675mA one I've already converted to get some more oomph from my lights. It would also give me the option of using the one I've already done with the narrow optic and fitting the more powerful one with a medium optic for a spot/flood combo.
BCT did hint at an 830mA driver, which I'd probably go for. Not sure about the 770mA mentioned a bit further down the thread though.

Will see what he comes up with!

My feeling at the moment is that the halogen can doesn't have enough metal to support cooling three LEDs at 1A. I'm thinking either 780mA or 830mA as the standard option for this with a 1A driver for the HID can which has more meat to it.

Yup - Just wanted to convince BCT that it is worth doing 🙂

BTW, if BCT reads this I am happy to make some heatsinks in my workshop if someone gives me a link as the one in the original article is broken 🙁

Ahh here we go:

BCT's updated post below that one though, says this:

'm currently building a batch of the lumicycle-specific drivers. I'm aiming to standardise at 770mA output but I could increase this up to 1A as the circuit is basically the same as my standard driver.

FR - pretty sure that BCT had come up with his own heatsink design that held the driver on the back and the LED on the front. I don't think it was that standard flywheel heatsink....

See here, I think: http://www.flickr.com/photos/50439158@N02/4631185669/in/photostream/

EDIT - I'd be interested to know how tight a fit this heatsink is in the can. The heatsinks I sorted out for my first conversion were slightly oversize and I sanded them down until they just fitted into the cans. This was in an effort to get maximum contact with the can to get the heat away.

Awesome - sorry the post was so long I got lost 🙂 Sorry 😳

Ahh - I dont have a lathe so cant make those - I could easily file down the ones above though 🙂 But the BCT heatsink looks spot on 🙂

I'd be VERY interested in a kit

FR - this is the heatsink that I came up with:

[IMG] [/IMG]

[IMG] [/IMG]

with the LED board fitting in the pocket and sitting against the back. I thought the sleeve would allow max contact to the surrounding can and is 'free' space that is otherwise taken up by the depth of the optic.
I made the backing plate quite thin (can't remember exactly, but perhaps 4mm) as I was worried about the depth of can available for placing all the other gubbins.

I wonder if it would be possible to combine the two designs to end up with a thicker backplate that would incorporate a cut-out for the driver, plus a sleeve reaching forwards to enable good heat transfer. With the driver placed into the heatsink there should be plenty of depth left for mounting the whole thing, especially if the resistor is now part of the driver board.

If BCT could provide me with a drawing of his heatsink, I could probably get my model updated. There is a chance i can get some made, but won't be able to make any promises on that front at the moment.
This design might enable more heat to be extracted from the LED board and allow them to be run harder, safely.....?!

Cool - nice one Stumpy - IIRC he's on hols this week so we might not get areply till next week but we should keep it up 🙂 I'll have a think too 🙂

I'm up for a kit for my Lumicycle can!

With the driver placed into the heatsink there should be plenty of depth left for mounting the whole thing, especially if the resistor is now part of the driver board.

Actually, this doesn't save you as much as you might think.

The can is 40.7mm deep. The optic + LED board is 13.4mm, so that gives you 27.3mm to play with.

The short side of the driver board, wrapped in heatsink is 21.5mm, giving 5.8mm for the heatsink. The heatsinks I had made up recently were 4.5mm thick, leaving a small amount to play with.

Even if you locate the driver PCB in the heatsink, the switch and power connector are only slightly lower in the can - the switch is 19.7mm deep and the power connector is 18.1mm - and that's assuming that you solder it so that the wires don't protrude any further. Allow a little bit for some insulation and you gain well under 2mm. The other thing to watch out for is the bolt for the mount on the bottom of the can, which is 19.7mm from the front of the can, meaning if the heatsink is thicker than 6.3mm, you need to work around that too.

You could get potentially more surface area contact with a more elaborate design that goes right to the back of the can at the top.

The above is all based on the Cutter XRE LEDs + optic. I think Cutter also sell some optics from another manufacturer that are a different depth.

Here's what I've got stuffed inside mine:

[img] [/img]

As you can see, the depth of the switch (including the white spacer) is very similar to the driver board. Also note that the resistor doesn't need to take up any useful space.

BlackCat's design does look very neat, and even if it only gets you an extra mm or so it's probably worth it and should certainly make assembly easier.

Here is one I have just done today

[IMG] [/IMG]

using a triple XPG and 20 mm triple optic .
a very tight fit in the can and only 15 mm deep so plenty of room in the can for the gubbins.

I have a few of he led boards with XPGs and a few with XPEs on with optics if any one is interested .

forgot to take pics and have packed it up for mailing

pdw, yeah it will still be tight. I'd probably add only a mm or so to the back plate.
I'll have a bit more of a fiddle around with this one tbh. Tempted to take the can apart, measure all the bits up & model them. Just finding the time to do it.

trout, that looks pretty nice. Presumably that slides in & the cap screws in as normal to secure it in place?
Is there any method of affixing the driver, or would it be a case of wiring in a normal driver and squidging it in?
I think I'll wait for BCT's heatsink integrated driver and give that a try - I have a couple of heatsinks waiting to be installed at home as well, so probably best that someone without the opportunity to get some made up snaps them up, trout.....

Hey Trout, do you still have those boards with LEDs and lenses knocking about?
If you do i'm interested, I've been looking at sourcing some for a uni project i've got on going on at the moment..

Nice one Trout - maybe an amalgamation with BCT and your heatsink and BCT's driver would be spot on? I feel a kit coming on 🙂 [Awaits BCT input from holiday] 🙂

I'd also be very interested in a kit, but knowing what to buy (and from who) is confusing.

If anyone wants beer tokens in exchange for LEDs/optics/drivers/heatsinks, my email is in profile 🙂

I would be in for upgrade kits for lumis as long as idiot instructions are available.

I'd be interested in a kit. Old lumi halogens have been taking up space in the garage ever since I got my p7 torch. Would need an idiots guide tho!

I'd pay for one too.

Would also be interested in a kit.

me too, maybe more than one kit as I have two lamps each for me and mrs nbt

Is BCT back from hols? 🙂

I have existing lights that I'd like to convert

Sign me up

i might be keen too (with idiots guide), assuming it would be as bright, and increase burn time.
i don't really understand lights though, tbh...

Been a bit busy with decorating the dining room to keep Ms T happy .

Lumi upgrade for spot it can have XPE leds and for flood XPGs .
comes as a sealed unit which is a press fit in the halogen can and by press fit I mean tight so the metal to metal contact is good .

will need a driver from BCT and I will do some instructions on how to do it all .

dead easy really
[IMG] [/IMG]

will be a diy or send to me for fitting

Hi Trout,

How much would I be looking at for a spot and a flood? I've got two old lumi cans that would benefit from just this upgrade 😮

me too. 🙂

Hi Trout
I'f br interested in a spot flood combo as well.
One question would these be ok with the Lumi nimh battery?
Cheers
paul

£27 for the drop in ( press in ) per can posted
You will of course need the driver from BCT .

or mail me for a price for me to do it .

Not sure about the Nihm battery but as long as it is over 12 volts then it should be OK

I'll have a drop in please for the lumi can. Should be ok wiring the driver by the time I get around to doing the DIY CK light!

Trout,

Sounds brilliant. Roughly what is the output of these individual cans please? Compared to the twin halogen of around 1000 lumen (?? fresh battery or 10 minutes before it drops) (according to lumi website for 12 and 20 w combined)
I am in for a few of these when we have BCT's driver availability and price.

Paul

I'd definitely be interested in buying a drop in spot to start with and maybe a flood later on. Might be a couple weeks before I have the cash though. e-mail - bikeandy61@gmail.com when they are available please. Ta fella you're a busy man and very generous with your time.

Will I need the 970 or 670mA driver from BCT, I have a Li-ion 14.8v/4.8mA Lumi battery?

Ta

a triple XPG running one of BCTs drivers on full will be on paper lumens of 1050 lumens.per can.
there will of course be losses so real out the front lumens will be more like 800 per can.

I have never had a working Lumi halogen in to compare as they are bust when I get them.

the XPE will be down about 150 lumens but will have a tighter beam

current nimh batteries are 13.2 v, mine is about 6 or 7 years old though.

got 2 working spot halogen lumi cans that would benefit - will email you about doing one - got a Lumi 3 to replace my halogens so this would be more to use as a loan light for other riders

I've also got two working examples for you. 20w flood and 12w spot. I'd be looking to change both for more light and increased run time.

I'd have to get you to do everything tho if you're able; how much would that be?

Trout,

Which bct driver are those figures based around? With the ones already available on ebay and the talk of custom ones above, what would be a safe max output given the lack of material in the can.

How floody and spotty are the LEDs? I'm using a Lumi HID as my main light at the moment and was thinking of getting one of each, but am wondering if two floods would be better.

pdw,

I see you've used a resistor to give a low power mode, what rating is it? I can't quite make out the colours of the two dark bands.

It's been a while since I last did anything with a soldering iron and this is wetting my appetite nicely 🙂

Calling BlackCatTech!!!! - Any more news on the Lumican Driver you are working on - Getting darker 😉 Tried to email you but your obviously snowed under of fed up of people like me emailing you 😉

Trouty, I've e-mailed you for a price on you doing the upgrade. Unless it involves a hammer, I'm probably best to leave it to someone who knows what they're doing. 😛

200k

According to the docs for the Black Cat driver, there's an internal 200k pull-up so, this should give half power. I only had it running very briefly (I'd managed to damage the LED board and am still waiting for a replacement) but it seemed to give more than half brightness, so you might want to experiment with a lower value if you want something significantly dimmer than full power.

Know b*gger all about LED's - can this kind of conversion be done on old Cateye ABS 25's?

Hi Trout,

YGM

Trout

I have an old set of Fireball cans that look like the Lumi's. Have you any experience with these? Wondered if your led's would fit?

Anyone heard from BCT, pretty keen to get this sorted
Cheers
paul

I have emailed him 3 or 4 times and nothing so don't hold ya breath.

Bo who:-(

I am still waiting for a reply too. Also waiting for a reply from Trout about two lights.

Paul

i am in for this if the kit can be fitted with no soldering and just mechinaically fitted and gives a good output for 3 hr batt on an old pro batery.

message me if you have a product.

Time to pop this one BTTT
Cheers
Paul

Anyone heard from BCT?

Nope or Troutie 🙁 Given up 🙁

Sorry fellas been a tad busy just lately as has BCT .

My heatsinks have been delayed at the machineshop as they are to them low priority
but I am hoping they will be done very soon .

I am doing the odd one on my lathe time permitting but time seems to ba at a premium with the missus press ganging me into decorating 😥

Thanks for the update Troutie. Please would you put me on your list for a buyer - impatient as always, FXR 🙂

Fair enough Troutie, but we are not getting much response from BCT about the drivers. 6 weeks and the nights start drawing out again;-)

Just to pipe up here to show I'm still interested.....

I did wonder what the progress was with the combined driver/heatsink kits, in terms of when they'll be available & what output they'll be.

I was going to order some of the normal 670mA drivers from eBay over the weekend, but I really want something with a bit more oomph.

I keep checking this thread too. 😛

Thanks for the update Trout. I sent a mail from your website too. I would like 2 wide XPG's modules please when they are available. If you have 2 spare narrows XPE's at the time and funds are right I will have those as well. Just need to know which drivers from BCT to get for the NiMH's.
Cheers

Paul.

This is the link to BCT's heat sink details from the old Lumi can thread.
Cheers
Paul

bah, I thought we might have an update.

do we have a ball park figure as to when these drop in jobbies may be available? Is it likely to be in the next week/month/before xmas? My lights are very tired and I'm holding out before I make a decision on what I do.

not trying to hassle I'd just need to get an idea please. 😛

From the other Lumi DIY thread, I think that BCT is waiting on finding someone to machine up the heatsinks....he posted a link to what he needs over there.

I am able to get the odd sneaky job done, but not any great quantities and not at the moment as they are flat-out with other stuff.

heat sinks just been delivered .

[IMG] [/IMG]

I have only a few led boards left all with XPEs on so a spot beam .
until some more come in in a week

That looks good mate.
Could you do a idiots guy to connecting these to a Driver please.

So are we any nearer having a kit then?. I hope You and BCT are making some cash out of this, Trout, after the amount of free advice you folks have dished out on here over the last year.

troutie

Looking good I will defo have kit if doing one.

looking good 😉

I would need a drop in (minimal work) jobby in the flood option. I'm getting all excited. 😛

TROUT,

SENT YOU A MESSAGE ON YOUR WEBSITE CONTACT LINK.

Cheers

Paul

Looking good there! Still want a kit for me please.

all good for me too - Troutie, put me down for a kit as well when available. cheers

I would like to thank Foxyrider for starting this thread, and Trout & Blackcattech for supplying the goods. Thats because, I now have two xpe powered cans, they blow my 20w mids out of the water, it's not worth mentioning the 12w spots.

Thanks guys, I look forward to getting the XPG's when they arrive.

Paul.

Any more news? 😛

Seems someone bought all Cutters remaining XPG stock 😳

I have a few of the triple modules that Paulb used with XPEs in they give a nice spot beam
also have some more of the triple LEDs on the way. but again with XPEs on board.

Probably won't be any with XPGs on this side of the new year

Oh Bum 🙁

As I have said before I am up for a twin XPG kit when/if you have one Troutie 🙂 Could you reserve me 2 heat sinks for when you get the XPG's in 🙂

P.S. Thanks Troutie for keeping us updated 🙂

Okay, no problem. How much for a drop in (I.e. Any numpty can do it) unit using the xpe LEDs? I don't mind waiting on the flood and getting a spot first if that's possible.

Ta very much 🙂

are the spots not available either?

Hi Foxyrider, Trout and BCT,

I am new to this thread but would be interested in getting hold of 2 kits if they are being sold as kits, one spot one flood so i guess that is one with XPEs and one with XPGs, I realise there is a holdup with the XPGs and can sympathise with trout’s demands of his real business however even if i can get the stuff in the new year that would be great.

I don't know the best way to go about contacting Trout or BCT or if i should put my request to Foxyrider if someone can advise that would be good.

Thanks

Rusty

Rusty Mac

Trout - click on his name at the top of the post and it will take you through to his website and use the contact link.

BCT - I think you can do the same or type blackcat tech ebay and google should find his shop on fleabay, order and they will arrive very promptly.

PaulB.

YGM Rusty Mac - As PaulB said mail troutie / BCT and put in your request 🙂
