Test/Review of Qlite Rev.A 7135*8 Multiple Modes Circuit Board 3.04A

Does the Nanjg 105C also turn the LED off when voltage is too low?
I know it has low voltage warning but i remember nothing about what happens after the warning

Also they look like the same driver, this one even has 105C written on it, are there any differences besides the 380mA chips instead of 350mA

Nope it does not turn off. There's also the whine present on lower modes (that also depends on hearing condition which gets altered with age, I do not mean sound pressure but frequency range).

They are the same driver, except for the program in the microcontroller.

ALL the 105Cs are the same hardware, only physical differences being the number & current rating of the 7135s. Everything else - how it handles the low battery situation, modes, PWM frequency (which is what causes some of them to squeal, and others not), what the stars do (or if the stars are used at all), ALL of that is down to the firmware version loaded on the MCU. All of it can be changed with different FW.

Just for reference the Qlite in Intl Outdoors ALXM module steps down to low mode. I have mine configured default low-med-high.
My runtime graph is here:

Thanks for the review. I am about to attempt to install one. Looks like I will be happy with the driver. Think I will choose the 4th star.

not sure when reading your review... Does this have PWM on High?

Just want to confirm - there is no PWM on high.

Yes it has a PWM as you can see on the graphs because they did not program it in a way without PWM in the 100% mode. So it’s not 100% high but unnoticeable bit lower.

HKJ:
Why did the original Nanjg 105c had a drop at higher voltages and reprogrammed Qlite version did not?

Different measurement? 380mA somehow magically perform better? Or was better cooled?

Another, why do the photos of Nanjg105c and it’s measurement signal a 8*380mA instead of 8*350mA? It’s supposed to be 7135s with 35x not 38x and have 2800mA not roughly 3000mA as in the graph.

Bug somewhere?

It does never turn the pwm completely off, but you will not be able to see it.

The magic is a high speed fan placed close to the driver, i.e. it is much better cooled.

I cannot answer for what 7135 chips are mounted on the drivers I get.

Ha!

Sure. I have a few but none 380mA versions and all my 350mA 7135s are marked 35x as in 35 and some random letter, M, P, T, or whatever. Where as on pics in shops I can see on the 380mA versions that they are marked 38x and 350mA versions are 35x. Although those spare 7135s on a reel seem to come from a different supply/manufacturer and are marked differently 7135 1234 etc.

So I think they sent you 380mA version with 3.04A instead of 2.80A :wink:

It finally got “warm” enough to step back into the garage for some soldering.

I decided to try the 4th star moon set.

I’m getting: nothing - low - med - high.

Fresh charged KP 18650 2900mAh
XP-G2 on Noctigon

High - 3.00A
Med - .765A
Low - .05A
Nothing - .003A

No output in “moon.”

Wouldn't happen to be de-domed, would it?

Everything is stock, dome is still on.

I've only seen that with potentially not-100%-healthy LEDs, de-doming sometimes screws with the Vf especially at the very low end.

It may not be 100%. It’s a 1A that was transferred from aluminum to Noctigon. Oh well, no big deal. I’ll try moon with a different emitter I guess.

Bring back to reflow temp and push down on the emitter while its hot. Let cool and try again.

Maybe some component is leaky.

If it puts the right voltage to the LED and the LED doesn't light up, it's not the driver.

this may sound crazy, but is the room dark enough when you test moonlight?

Yes, it could be the led that is leaky or the garage.
