BLF GT official support thread [FAQ updated 11 Jan 2018]

Moon light is always an extra add on. If you choose mode 4, you actually get 5 levels due to moon light being turned on. Mode sets in general are not that fleshed out. It’s mainly meant to be used in ramping mode.

Another user, WaylonJennings, has mentioned that when set to mode set 7, if he removes battery power then reconnects, the light jumps back to the default ramping mode.

I don’t have my light with me to check, but can someone see if this is a bug in v1.2 or just a one off fluke?

Definitely not a 1.2 bug. Just tried it again now to be sure (several iterations, each with different timing).

There is a (very) small chance that the MCU browns out during power-up or power-down, messing up the settings memory in the process. But that should be a once-shot deal and the light is more likely to temporarily lock up than change settings.

Hopefully Tom or TK can chime in.

Yes, MOON doesn’t count to the numbers of modes. Nice, that you found it out by yourself.
(The same user questions like with the Q8. :slight_smile: )

The Notes section on the cheat sheet is derived from user feedback with the Q8.
If you have a problem with the UI of NarsilM, there is a good chance that it’s mentioned there.

Hi,
does anyone know, if Sanyo NCR20700B does fit into battery carrier and GT Tube?
Thanks a lot.

No, they are too big.

LOVE this thread! Very very well laid out. Thank you guys so much for all your work on this!

Is anyone able to tell a difference in light output between normal high and turbo? I can’t but I figure it would be more apparent at long distance vs the small room I am checking in.

The output difference is very minor and hard to notice unless you go directly from the top of the ramp to turbo.

If your batteries are low, then the driver will have dropped out of regulation and there will in fact be no difference in output.

I can tell a difference when it’s sitting on the end of my lumen tube :slight_smile:

I just noticed something. In the modes group if I set moon mode to the lowest setting it doesn’t work. It basically makes the light be a double click to turn on. Was this on purpose?

I believe your talking about the moon level 1 to 7?

Level 1 is not guaranteed to work. It depends on the particular emitter whether it will light up or not. This was also true of the Q8. It’s also why level 3 was set as default as it should be more likely to light up, yet still be fairly dim.

I think you will find that your light will also not light up in moon mode in the ramping setting.

The only way to access moon mode in ramping is to turn the light on by a press and hold and then quickly release the button before it starts to ramp up.

BTW, ramping only goes down to the equivalent of level 3 moon mode.

Cool, that actually makes sense. I will mention that in my vid. Thanks again!

Your vids are hilarious, especially that opening scene in the vid in the OP (some acting skillz!). Always appreciated. Am looking forward to your XHP70.2 mod vid. May want to get a second one for that purpose

Thanks Team btw. What an amazing effort, from inception to development, and now support. I’m honored to be part of this great community. (I signed up on BLF, after lurking for a while, just to get on the GT groupbuy [and many groupbuys later…ouch]).

Jason, I noticed @ 1:50 in your light make the same glass popping noise mine does… About every ten minutes mine will do that LOL!

I’m not sure if it affects NarsilM, but in RampingIOS one of the things I fixed was a race condition of some sort which could occasionally corrupt the eeprom. I don’t recall the details exactly, but the patch is in the repository. I think I changed it to A) use library functions instead of direct register access, B) disable interrupts while saving, and C) erase before writing instead of vice-versa. I haven’t heard any prior reports of anything like this for NarsilM though, so perhaps the issue was only in RampingIOS v1.

Yep…. that is the exact same sound mine makes too. :+1:

Great video also Jason, thank you! It answered in a simple to understand way what I was trying to figure out in the blinking modes. :slight_smile:
A huge help……. :+1:

Here is my take on the UI :slight_smile:

A lowe case fits the GT
