Arrived
No ring, again……

Arrived
No ring, again……

this happens too often I also had some drivers without rings lately
can you confirm it fits the light?

but it will be OK if you add a thin solder layer to the 3 screw spots to make contact with the brass ring
simply the metal layer needs to be higher than the mask paint

mail Oshpark and they will fully refund the drivers

and instead the 7135s more reliable regulators are those

My thoughts exactly WTF (and hIKARInoob). You hit the nail on the head! :sunglasses:

Acebeam is really good at having a mode on its line of flashlights, that hits its heat dissipation sweet spot, exactly.

Take the newer X45 for example. Capable of putting out a total of about 16,500 lms. On high, which is a 4000 lm level. It can be turned on at that level, and it will stay there, with no step-downs, for 1.4 hours. At which point, the batteries can no longer maintain that output.

Even on the newest Acebeam X80. Which is a smaller sized flashlight, but capable of putting out approximately 25,000 lms. They pushed it even harder. In the high mode, when the flashlight is cool, and the battery levels are full. That flashlight can be turned on in high mode, and run at 5000 lms for 20 minutes, and then, it only steps down to 4000 lms. For the remainder of what the batteries can handle.

The Acebeam K60. The same way. Turn that flashlight on in level 6, and it will give you a constant 5000-ish lumens, for over an hour.

I too, would love to see more flashlight manufactures work on getting a ‘sweet-spot’ level figured out, and programmed into their flashlights. That they will maintain, from a cool start.

I’m a bit skeptic that the X80 can put out 4000 lumen OTF continuously without getting blistering hot.

Has there been any update on the battery compartment with regards to the size of batteries this will accept. As it stands it will only accept unprotected flat tops?

I believe the production light will only take button-top batteries.

Lexel in the OP said

“The light is build for unprotected batteries, protected or button top unprotected won’t fit, the ones I have with a 2mm brass button fit barely
On the left the one with the brass button and on the right a flat top battery”

ENEDED

One thing is for sure, you cannot use flat top in the new battery carrier. There will be plastic insulators on the anode (+) ends to prevent loading batteries in reserved direction. I suspect you can remove them but you will risk damaging the batteries or even light if you make a mistake for the polarity.

Yes, very perfect

I try to make another use of the NarsilM firmware driver.
Not working properly still.
After installing the battery, direct light high, and then will not light up again.

I'm responding on the NarsilM thread.

@hIKARInoob

Edit:

Based on the run time data, I see a possibility that the light steps down aggressively when reaching 60 C to the 1100 lumen mode (for the Nichia version), and stays there until batteries are depleted. So there is no feedback control for output as a function of temperature.
If so it’s a bit unfortunate that there is no 2500~3000 lumen mode where the light can sustain output fairly continuously.

I did today a measurement of the beam intensity of this light

measured @5m 2080 Lux cold start

so I get 52000 Lux @1m for the Nichia pre production light

this is just the Luxmeter set to show save max.
starting the light, 3 clicks to highest mode
then move the light a bit to get its peak output

Two big thumbs up!

Is there a likeliness that the driver spring might bend when tightening the battery tube, causing a short? Something similar happened with an Acebeam K70 here: http://www.candlepowerforums.com/vb/showthread.php?436281-Should-I-be-scared-my-Acebeam-K70-might-explode

What do you guys think?

[Lexel]

This can not happen with the MF01

I did not show a picture from the driver with the insulator inserted

Basically the platic insulator you see on the carrier here fits inside the insulator on top of the driver the distance between spring and ground is 12.5mm, also there is no ground spring

And the distance between pisitive spring and the ground ring is 12.5mm

[hIKARInoob]

Aha, thanks. It’s a plastic ring on the driver side. The picture on the Banggood site showing the three parts, head, battery tube and tailcap, made me worry it might be aluminium.

[hIKARInoob]

Ugh… First video of busted MF01
