Highly unlikely. I’m guessing it ramps all the way up to 600 lumens. I don’t see the point having a higher turbo being a lantern that’s designed for runtime


This is correct. The LT1’s primary purpose is to be ‘enough’ lighting to let you function normally over an extended time. In a situation where normal lighting is not available, this should be enough light to allow it. It was never designed to replace a 200w chandelier.
I’m pretty sure you’re both incorrect. We went over this when working on the manual. As it was explained… By default the light does not ramp all the way to the max possible output. It ramps to the “ceiling” which is not the max possible output. As such, the “turbo” is brighter. You can change the ceiling to the max possible output, but that’s not how it ships.

Of course it’s always possible that we were given incorrect information despite making every effort to ensure the accuracy of it.


I’m just going by what TK said way way back…

About the level 65 thing… It is behavior inherited from other lights which use the same firmware. On many of them, the default ramp goes from 1/150 to 130/150, and then there is an additional turbo level at 150/150. When it turns on, it tries to hit 65 because it is visually halfway up and makes a good “medium” mode.

On the lantern, there is no turbo by default. It’s not bright enough for that to make sense. So the ramp goes from 1/150 all the way to 150/150. It still defaults to level 65/150 after a battery change though, since it’s still a pretty good “medium” mode.

As for the floor and ceiling levels, the ceilings are both set to the highest level by default. The smooth ramp floor is set to the lowest level. And the stepped ramp starts at 10 and has 5 steps. Smooth: 1 to 150 Stepped: 10 to 150 in 5 steps: 10, 45, 80, 115, 150

Anything is possible… The manual now says that the ramp goes all the way to the max possible output level. It also says there’s a turbo mode. I can’t vouch for the accuracy of it.

TK may have changed the final release of the firmware for the production units, i am unsure of that. but the production prototype i been testing has a smooth ramp that goes from roughly 10% up to 90% brightness, the 90% being the ceiling of the ramp config. A quick double click brings it to 100% maximum. Technicallyit is not a turbo as it don’t step down & is not a “overdrive” mode like some flashlight turbo modes are considered. The stepped ramp config goes to 100%

Did anyone succeed in ordering from ebay? I made an offer on the lamp with batteries and included info (didn’t get a code yet) but I didn’t get a pm and the offer has not been accepted. Do I need to wait for the next batch? I got no issue with that I just want to get it ordered so I’m not forgotten Silly

I added everyone up to post 8052 but of course anyone added since Sunday won’t see their names on the lists until next Sunday’s updates. Hopefully Sofirn is downloading the latest lists but this might not matter until batch #2.

Don’t laugh too hard. The Streamlight touts it’s ability to float as a feature.

They could make a white version LTM with floating base and stainless hardware as the “Marine” unit and charge way more just because it’s “MARINE”!

Hi people, If I use Panasonic 18650B protected Thrunite re-wraps, 8 to 10 amp capable, would it affect max output compared to solder blob 30Qs?

They will work fine Thumbs Up as long as they are button-tops. The LT1 don’t pull much amps from the cells, and don’t need high-drain cells like the 30Q.

We’re at 2,878 after the latest additions. Since Sofirn said they will produce at least 3,000 lanterns that means that everyone currently on the list will be able to get a lantern. As long as nobody orders more than they are in for.

I know that some people are somewhat stressed waiting for a PM from Sofirn but I’m confident that all who currently want one will end up getting a lantern Smile

I added you to the interest list so at some point someone from Sofirn will send you a PM with an Amazon code and buying instructions. Based on what people have been posting don’t expect a PM for several weeks (at a minimum).

I have a question regarding those who are interested in multiple quantities, since the current limit is 1 per person (or it’s 1 unit per order).

I’m already able to order from AliExpress by indicating my BLF name. But wondering, approximately when can I order my next units? (I understand they will probably be “batch 2” and should still honor the “group buy” pricing)..

  1. Got a China Post tracking number via Amazon DE today, two days after ordering the light. I appreciate that it is probably just a pre-advice but still pretty impressive.

No luck as of yet, on my third attempt now. All have expired so far. I have noticed it looks like they have sold 1 since Monday (from 40 units sold to 41). I hope the sale rate picks up a bit!

Please add me for a third lantern.

Thanks to all those who made this happen. I got my codes and have placed an order for my first lantern, I’m hoping to use my second code for a sand version, and the third for a green one.

Any idea if the codes will expire before the color options are available?

Sofirn said they were good for 30 days but I don’t know if that meant 30 days from generation or 30 days from when they were sent to people. No doubt they can extend the expiration if they need to do so.
