YEZL Y3 CNQUALITYGOODS Group buy. 3 Versions. See post 274 for delivery details.

Hehe nice Tom… Mine actually went the other way. I now have .03a at the tail on high using 3 batteries. I’ll mess with another set of resistors tomorrow. I had things to get done today too- my other half is mad… Like fack a flashlight mad. I noticed that about the emitter though. Does do better inside the reflector. I’m just gonna have to order a set of smd resistors it looks like.

100 and R100 are not the same thing. The “R” is a period, so R100 = .1 —- get it? I don’t remember ever disassembling a thermostat, but I doubt that it had an R100 in it. If you replaced the stock sense resistors with a pair of 100 ohm resistors then you are getting approximately the right current (seems a little high, but the formula is less accurate when you take current so low).

“They” don’t sell SMD resistors “here” either, we all have to order them over the internet except maybe ryansoh3 I suppose. Mouser or Digikey are the fastest way for those of us in the USA / North America, Fasttech is the cheapest source for a couple of values in 1206 size and several more values in 0805 size. Maybe you should establish exactly what you are trying to do and order the appropriate parts. At this rate you’ll kill something soon. Note that nobody is selling sets of sense resistors. You’ll need to purchase those individually, the sets are all of much higher values.

EDITed

Sounds like good work. FWIW I just want to point out that your lowest value resistor, by quite a bit, is the 0805 sized one. It’s going to be carrying nearly half the current by itself with a 250mV drop across it. Best case scenario it’s rated for 250mW of dissipation, but this is probably 500-600mW. 1206’s are probably rated for 500mW, so switching to one of those could be a good idea, even if you are going to pot it. Other than that, I assume that the baby FET is the weak point.

I have not received mine yet. Are the stock sense resistors 1206 or 0805?

Yeah we have two decent shops here. Whitcom just don’t make enough money selling smd and Sparkey’s didn’t carry R100. I can barely read those dang things as it is. I should go down to schneider electric right next door. They used to be Pelco, make surveillance equip. I’m sure one of the programmers could hook me up.

Pulled 2 off the school thermostat and that’s what I got. Yeah your pretty informative wight :slight_smile: Bought 5000 assorted off ebay for 10 bucks already. That should do it, but no flashlight messing for least 3 weeks it looks like. China shipping. :frowning:

Oh well, I tried. I’ll make my way down to Schneider tomorrow. I’d like to see this thing work so I have enough time to order another one before October.

Edit

I went through the camera, I took this after laying in the first resistor- 100 xd On low I can see the emitter clearly without sunglasses. Kind of cool in a way, like a cool white light. I really hope I can get ahold of a couple spare resistors tomorrow. I should do a WTB on craigslist too like a crackwhore looking for a fix. Wight you sure it can handle 5 amps? Or should I do something more conservative with this. I’d like to push it to it’s limit on high, probably run it med most of the time though.





I wanted to ask you guys too. Do you clean the reflector? Any imperfections are noticeable. I blew it out with compressed air and was going to take lens tissue to it- then thought, what if the chrome layer scratches or comes off. I dunno just thinking too much probably… Let me know (before I ruin it)

Dont touch the reflector. You run the risk of ruining it. Some reflectors mark by just looking at them.

Nice effort guys on the MTG-2. I have a HD2010 running at 2.7 amps and it puts out an amazing amount of light for such a small current drain.

0805's are stock - I should have mentioned that, that's why I used an 0805. So, you think these are current limiting and not current sensing? I was thinking sensing and that's why they used smaller ones, but I had no clue.

Yes, I'm thinking it could do better - reflector is probably blocking, being loose, and upgrading to 20 AWG wires may help a bit too. Without knowing the amps to the LED, hard to say it's performing at its best. But, it still looks pretty nice - love the beam pattern. Only other MT-G2 mod I did was a much smaller light, and this one is definitely brighter and has better throw by far.

Are other people still waiting on theirs? My tracking number still returns no results, track17 will recognize it as China to US but shows no info.

@FFT

I never touch a reflector over dust/ one little spec, it’s not worth it, I use my compressor to try to blow it out but that’s it for minor imperfections. For larger issues, a dirt spot / a print / oil / grease I use the microfiber cloth that came with my Chris Reeve Sebenza, I wash it [the cloth] first and the very gently wipe, not with direct finger pressure, I use just the corner of the cloth. It works pretty well, of course my preference is not to need to do anything like that in the first place but it gets the job done.

I use the same cloth for cleaning all my lenses, something about that material is perfect for getting finger print oils and other shit off AR glass and PVD reflector coatings.

Still. Ric doesn’t answer to PMs. cnqualitygoods@hotmail.com also silent. Two weeks passed from fake shipping date.

I am also waiting on mine, I’m not surprised or concerned. FWIW CK and I both ordered after the initial shipping batch.

Ah thanks Mr and CK… I was about to wipe it the other day and get irish rage. Have some microfiber cloth that came with the garmin, but I’m sure it’s dirty- using it to wipe off all the fingermarks you get on that thing. Have to get some more camera lens paper and make due without pushing into it. Got another light on the way from gearbest. Almost bought the mt-g2 last night too but something keeps nagging me about it. Already have a good floody light. I wish I could see like toms version in hand or something.

Oh yeah wight, going to try a little lower on the sense resistance when the smd get here too. Maybe 5.5a, reading around some. I wish you had yours so I can pick your brain some more about resistor size and pushing this to it’s limit before it breaks :slight_smile:

Exactly the same situation.

Ciao

If you got caught up in a second batch send, when the lights get to the airport in China and show up in 17track, sometimes (most of the time) they can sit around at the airport for days, even weeks, waiting to be considered a high enough priority to send. Weird how they handle that over there, but eventually it gets put on a plane and makes it to the Country of destination where you’ll see it again in 17track, after that it’s still guesswork as to whether or not it gets scanned and you get more info.

patience, grasshopper

:smiley:

Just got via email:

Same day later:

and later:

I wonder whos were returned and why they were returned.

Mine arrived today. Packaged the same as others described. (Two nested bubble wrap bags with lots more bubble wrap wrapped around them.) I haven’t had a chance to inspect them super closely, but I’d say mine fared better in terms of dings. I didn’t see anything that didn’t look like it happened on the manufacturing side.

Keep us updated. I ordered another AR lens from cnqualitygoods for the other one. I got thinking about Toms mod with the modes too. That would probably be better for hunting with the on off on the switch. What driver and tools would I need? I saw another thread but I’m not sure if that’s the same driver and where should I order. I can mess around with the code but I’ll need the driver, pick up the hardware to flash it in, ect.

Ben

Oh yeah got thinking about my big light too. I think I can air cool that sucker xd I’ve already visioned the airflow through the pill. But one thing at a time.

And again cnq has messed up my order… :frowning:
Tracking never worked and today I got a message that they reshipped it, so here we go another month of waiting.

I will never order from them again, i hate the fact that they send my orders with small amount untracked despite they mark it as “free registered post” and that this orders get lost in 50% of the time the shop is crap for sure too… And now this….


Are the returned shipments all from buyers in Europe?

I just got the following message.

It is a little annoying but I can't really see how this is Ric's fault. I'm sure he is no more happy about it than any of us. Just have to wait a little longer.

Hi
Sorry to inform you that package has been returned to us.. We resent it by SG registered post.

Your order has been shipped by SG registered post.

New Tracking number
RQ...........
Thanks
RIC
