*BLF LT1 Lantern Project) (updated Nov,17,2020)

I am unsure how long the codes last or if they expire, or will work for the later batches. maybe Sofirn or Barry can answer that.

I received more than one code for my three early spots under 500 back when they started sending them out, but since we were asked to only order one, I only attempted to order one LT1. I figured that getting multiple codes was probably an error, and either the code would still be honored once we are able to order more lanterns, or codes will be reissued if they expire. Regardless, I didn’t have any problem waiting a bit longer for something so worth waiting for. After nearly 4 years for this project to reach this point, a couple more months so everyone on the list can get one before I purchase my remaining spots was not a big deal at all. It also helps ease the impact on the bank account. :partying_face:

Since it was promised that everyone on the list would be able to purchase their lanterns at the group buy price, and reading this entire thread over time, I am confident that there is good will at work and with patience, things will be taken care of and made right eventually. :smiley: What a great reward for being patient is being embodied in the absolutely wonderful example of a LED lantern that is the LT1! :partying_face: :heart_eyes:

Thanks very much to everyone involved for all the hard work, you have much to be proud of! :beer:

BLF member GreenCampfire has been doing some good run-time testing of the LT1 lantern in factory configuration with graphs, the testing can be viewed here: BLF LT1 Runtime test *updated 12/11 with step level 2*

I cannot use the code. It says
Ptomotional code cannot be applied on my purchase

Since the codes last through December, does that mean that the codes won’t work for the colors in Batch 3 or we would be issued new codes instead? Thanks!

Send Sofirn a direct message with your code issue, they should be able to fix that issue.

I am unsure of that, Sorfirn or Barry can answer that hopefully.

Sorry if this is a dumb question but its the LT1 supposed to thermal throttle? I forgot to lock out mine and it turned on inside my backpack, after 2 hours when I picked up the bag I noticed it was warm… the head of the lantern was too hot to touch and the batteries and carrier were warm, even my L21a that was inside was warm too.

Maybe it was too much heat to handle? Should I calibrate the temp sensor? Again sorry if this is normal in a closed environment like a backpack, I really like the lantern and would be sad if it burns itself down lol

There is no thermal regulation in the LT1.

At room temperature without cooling or air flow, the LT1 with all chips enabled eventually reaches 62 degrees Celsius on top which is hot but a very safe temperature.

In a closed environment like in a backpack, if switched on at full power, the LT1 will get much hotter of course, but as other flashlights, it probably can handle well over 100 degrees Celsius before damage occurs. Given that too hot to touch already starts at 55 degrees, there is quite a lot of headroom there before things really go wrong with the light. So your LT1 will probably be alright, but of course that can be different for the other stuff in your backpack.

Next time locking out your lantern may be a good idea? :wink:

Understood Thanks for your answer!

Yeah will do! I have learned my lesson with my SP36 but since it is the first time I throw it in my backpack, I completely forgot to “4Tap” :person_facepalming:

I still haven’t bought the first one.
I have the code but I prefer to wait for the orange version (at ebay).

I haven’t purchased the first one either. Probably not going to. Not that it isn’t a great offering at a great price, it is, just that there are other lights I would prefer and CAN’T BUY EM ALL!

Is it too late to get a group buy code for Amazon? @sofirn

You should PM that user directly. I don’t think the board is infected with ` automation.

Sorry, searched and could not find the ‘dimensions’ of the lantern. I want it so I can shop for a cheap neoprene camera lens case to protect it. Anybody know the dimensions?

We need a LT1 wiki. Too much non-factual info (questions, tears, etc) in this thread and would be great to have a reference.

Just found a tint ramp bug on my LT1. You may reproduce it as follows:

1. Reset to factory default (not really necessary, just to ensure a common beginning)
2. Enter the lowest brightness with the default stepped ramping.
3. Ramp the tint to the warmest or the coldest side.
4. Now stepped ramp to higher brightness levels, and you’ll see it. If you chose to ramp the tint to the warmest side, now the tint gets cooler when the brightness is ramping up. If you chose to ramp the tint to the coldest side, now the tint gets warmer when the brightness is ramping up.

Not a bug, but a feature? :stuck_out_tongue:

I’m unable to flash my LT1 because the programming holes don’t work as they should. I explained the programming issue here: BLF LT1 Runtime test *updated 12/11 with step level 2*

It is not a firmware problem, it is the design. One can choose to have warm tint at low light, and cool tint at bright light, or the converse. That has been discussed in this thread previously.

regarding the programming pads,

Not sure what version of the programming key you have, but it appears some small mods need to be made to work with the LT1. I don’t know anything more than this regarding the key. I do know that connecting directly to the chip works fine.

It’s supposed to do that. :person_facepalming:
