confusing (to me): new driver@intl-outdoor: Nanjg 105c with wonderful modes

http://intl-outdoor.com/qlite-71358-multiple-modes-circuit-board-304a-p-...

The driver brand is described as Qlite, but the pictures show exactly the well known Nanjg 105C. The modes are a bit different from what we are used to, so apparently it has different software (someone out there reads BLF? Smile):

*Group of modes:

 

1st  Star  : 2% - 25% 100% (Default)

 

2nd Star : 5% - 30% - 100% - Strobe (10Hz) - Beacon (cycle: 2Hz blink, 4seconds light off)

 

3rd  Star : 15% - 100%

4th Star  : 20mA - 2% -25% -100%

Look at the first and fourth mode group LaughingCool

But what confuses me is that the fourth group has a 20mA setting which suggests that that specific setting is not PWM, but current controlled. How do they do that without changing components?

Anyway, I ordered two.

I ordered five of those yesterday. The ready to go default mode is hi-med-lo. I must remember not to bridge that third star like the nanjg. I didn’t even notice the 20mA on the fourth. I’d like to hear about it also.

On top of the nice modes it have nice features:
*No high pitch noises
*Low voltage protection: At 2.9-3V the light will switch to an emergency low mode. At 2.8V the light will automatically cut-off.
*3.04A (8*380)

I hate pwm noise/sound. But “no high pitch noises”? Love
Anyone have experience with that. Can this be a 8*7135 without the whine?

The only time I have noticed whine with the 7135 drivers, has been because of poor ground. Every time I have heard whine, I find the ground is not good enough and after fixing the ground, the whine goes away. FWIW

I have a P60 with a high pitched whine on med. mode only.

mother of god, nice find, that’s it, all previously owned nanjg drivers will be going into other peoples builds, then all my lights will be getting this driver on group four!

Thanks.

I just ordered one and I can’t wait to try it out. Group four sounds perfect. In fact it sounds almost too good to be true. But hopefully it’s the real deal, if so I will be ordering more.

I’m a junky, I mod lights so I can sell lights so I can buy more light to mod so I can sell lights to buy more lights to mod.

Another 5 less. I only just got bailed up for $120.00 from the better half now there is another $21.00. Any advice.

Edit. Her eyes aren't quite as good as they used to be. I've written it up in really small letters so hopefully she wont see it but I cant get blamed for not writing it down.

I found this one earlier this evening and ordered 2 of em myself. Might should have gotten more.

Sure hope it is what they say it is!!!

This is the only driver I’ve seen with beacon mode as the only blinky amongst the normal modes. Awesome for a dive light. Got to get some.

Three Tanna leaves to give him life, nine to give him movement. But what if he eats the whole bag?

The original driver on on of my Crelant V9 had one of the most annoying whines possible (so loud that everyone in the room could hear it) and it was not a 7135 based driver, eve so the build was hard core). I changed it to one of my old Nanjg 150C drivers and I basically re-flowed  the driver on the brass pill and the driver still whines.

All my EDC, Convoy flashlights whine intensely.

But let's be honest, with age the higher frequencies are simply inaudible, especially for men.

Truer words have not been spoken. Try talking to a woman thats as deaf as yourself (my wife) and the quickest argument starts as you do not hear properly what each other had said.

Pok: You could get a NANJG105C 3.04A with custom firmware, so you can have all the modes you want…

As most know. The whine is mostly on medium.
If you cant hear it on low, take it up to your ear.

I only use NANJG105C “programmed” to high/low. Cant stand medium.
Despite that I do have a typical 2-group NANJG105C in one of my flashlights, just tried to improve the ground, tested it on low and medium afterwards but still same whine. I tested the pill (with emitter and driver) outside a flashlight too. It whines either way. I have earlier used drivers with PWM boards directly to power supply without pill or anything. Still whine…

Id guess the ability to hear the whine is a combination of age and how sensible you are to the frequency.

The best 17mm driver I have is the one that came with one a P60 cooper drop-in intl-outdoor sold a coupe of months ago. Not available now. Its nicely regulated, have nice modes (100/28/1) and no whine. No components on the spring side of the board either. Low voltage protection/warning and high temperature warning. (The high temperature warning is not that useful though, because it does not lower the mode/output)

There are many drivers out there with PWM noise. I try to avoid them as good as I can.
I Just ordered one of these qlite from inl-outdoor though. Need to test it. Its probably the best 8×7135 board out there considering modes/features/price.
If there is no whine, I will have to order more! It could easily become my favorite driver.
Still hoping something good come can out of the lightmalls custom BLF 4A boost driver…

The whine comes from the switch. Hold the tailcap up to your ear and lightly press the button, not enough to turn off or switch modes, and you can hear the whine change according to thumb pressure. Usually means you need a new (or better) switch.

I accidentally flashed 101-AK-A1 with improper fuses which caused CPU frequency and thus pwm frequency to change (increase). Driver was totally quiet at 40/340/1000 mA.

Funny to hear. Depending on the contact the sound changes. I could get some funny noises when trying out SOS with a half pressed switch. No doubt worse contact leads to more noise.
But as I said. The whine is still there without the switch. Driver board only with power supply, complete pill+battery (no switch or body) or assembled light with a wire on the tail instead of tailcap/switch.

That’s why I recently started using 18kHz as PWM frequency…

Could poorly grounded chips be the cause of whine?

Is that done only by changing CPU freq. to 9.6 MHz ?

Now, why Im I so happy?

Three nice hosts, cooper sinkpads and some nice tint XM-Ls?

Nope, not it. The OEM D4 (aka Convoy M1) does not have a driver on that picture..

But now it does… Whats on the backside of that pill?

Ahh.. just a typical nanjg 105C…

Nope.. Not a typical one.. Its the Qlite Nanjg 105C!!! .. Arrived today, after only 10 days (new intl-outdoor record for me)!

Now, why so happy??
Because silence!!!!
There is no noise, no whine!!! Finally!!!!!
And yeah.. The modes are sweet.. I have only used it in default mode so far, which suits me perfectly..
Did a say its silent!!??

Love Party Party Party Party Love Love Love Love Party Party Party Party

Off to intl-outdoor. Need to get more of these lovely drivers!! 8) Beer Beer

Dang was hoping you had some tailcap measurements from the 4 mode setup! Thanks for the info though.

Thanks.

Looking forward to getting some too for the silence, I simply got fed up with those noises. I even reflowed one of the regular 105C drivers in a brass pill (so the ground connection is rock solid) and it still whines.

@chiefinspectorfinch: No, I did that by changing the PWM mode.

*fiddles around for a short time.. *

Ohh, 4 modes, these are nice based on first impression:)
Tailcap measurements with AW 2600, protected @ 3,9 volts.

0,01
0,05
0,8
2,91

Double check with NCR18650B 3400@ 4V (from intl-outdoor)
0,01
0,05
0,8
2,93

Based on my readings that equals:

“moon light”
1,7%
27%
100%

Changed setting on multimeter:


My DMM reads: 7,22 on that setting when checking the moonlight mode.
(take it with a pinch of salt)

So thats 0,00722A??

Im not used to moonlight, but for me, its really usable. Could be too high for low low moonlight lovers. But I have no experience with moonlight so what do I know.. Silly
Its not that much difference from moonlight to low..

Okay, it cant compare with the others in quality. And mine had some scratches on the body. But a decent XM-L zoom light.. Quite short, and okay heat sinking (for a zoom light). It ruined the 4000k tint.. It got a bit cool. Not a huge surprise surprise though..
These hosts are a great example that you get what you pay for. Not only in size but also in quality. (cheapest on right side)
