Suggestion: make the tripod thread on the tail the larger 3/8” size and supply a chromed brass adaptor to reduce it to the 1/4” size.

This is what e.g. Astrolux did on the MF01, and is a great solution to any concern of wearing/stripping plain Al alloy threads. The 3/8 threading is much stronger, and most of the time the brass 1/4” adapter will be used, and easily replaced in the unlikely scenario of it wearing.

No decent camera has threading straight into bare metal (or plastic), they all use a bushing of suitable metal, for good reason.

The threading does need to be deep enough to take a standard length tripod screw. For example, the thread on the Q8 head is far too shallow. I can’t attach it to any of my tripods without it bottoming out, or using a washer to make up the difference, meanwhile hanging on by just a few threads. On the Q8 the flat area surrounding the tripod thread is also far too small, no way to use a standard tripod because the sticky-out bits (technical term) of the curved head get in the way.

Don’t forget provisioning some way to hang this up, even a bail handle that could be clipped onto the head with just two small holes. Also necessary for walking about with it. Every decent lantern I have has such a handle.

My use for lanterns is base-camp, night beach fishing and boat fishing. Which needs a handle to carry it while walking, complete water-proofness, corrosion resistance (no not typical Chinese “HA3”, edit: and the threads protected inside the preferably double o-rings, not outside, see good dive-torches for how to do this), and a stable base suitable for any surface. And immense ruggedness.

Second duty would be domestic power-cuts.

Standby drain should be zero. This is where mechanical switches deliver. With E-switch there is always a slight concern.

Integral charging, powerbank facility etc. is low on my priority list. Efficiency i.e. run-time CRI and colour temperature (warm) is high.

Maybe you missed my last comment, but what do you think about making the battery tube a little bit wider, so that you could also use 20700/21700 batteries if you want maximum runtime? At the moment it looks like the battery compartment is the smallest (least diameter) part of the lantern, so that this wouldn’t make it significantly larger.

i seen it. it will likely drive up cost, but i can ask Barry about it. The intention to try to keep costs down on an already more complex lantern that first conceived was the plan to use already existing battery tube they already have for the Q8.

switch does not nessesarely need to sit in center, but my best recommondation would be that the top section gets screwed fom the driver cavity like the Q8 did, so you got no need to water proof the screw on top of the lantern and it looks cleaner

I like that idea too of putting the center bolt in from the driver side, as that will allow for a much deeper threaded section in the top solid part for more strength and as you mentioned a better seal.

it will have a carry lanyard loop, (para-cord is we can have that as its better) metal handles/bails have limitations, but it can be added to the planned accessory kit that can be available. (which also includes a sturdy plastic snap on wide base cap for more stability when packing it in a backpack is not a concern.)

Is there any info on the USB c charging and tint ramping? I’m really excited to see if the low tint will be all the way down to 2700k. I have a lamp by my bed with an Ikea 2700k bulb and the tint would be perfect for being easy on the eyes in a tent.

USB-C for the input charging is being considered if it don’t increase cost. (

All rightey then.

I also, as I have noted, am buying several lanterns committed to in the very infancy of the project. It is getting very old to keep seeing “alternety should not be allowed to have one of these lanterns [or Q8s] “ in various formats. I consider them very very rude. Regardless of opinion; alternety is neither stupid or nor uneducated. I too am an engineer. Engineers have a gene that requires them to evaluate everything. And, if necessary, fix it.

I believe most of what I have written makes sense. That is why I write it. But the regulars despise/attack it. Fine. Everyone gets to put in their two cents (I think).

I honestly don’t know what was rude about my last post. To those I have hideously harmed psychologically ; my apologies. And I have fixed lamp/lantern in my last post. My fault. Lack of precision. I hate it when that happens.

However, may I suggest actually thinking about some of the points and trying to understand the basis and results being discussed rather than having your knee jerk. I understand it is late in the project. I have provided input much earlier. To no avail. But hope springs eternal. I am trying to point out some possible issues or improvements with minimal impact. And improve overall user utility/complexity.

I made a suggestion earlier about polling the buyers of the >1000 lanterns about features. There is a skilled core development group working on this. Their uncompensated work is irreplaceable and deserves kudos. My point about polling is to survey the unwashed masses view of what is useful, required, or not wanted. Logically, there are a lot of potential buyers that simple do not participate in (or understand) the definitions of the lantern. They just want the lantern; whatever. Rather than build a complex (and potentially more expensive) lantern for a subset of potential users; go for most useful and lowest reasonable cost. Reverse the point of view. Simple now; complex next rather than complex now and simple later. This has significant marketing issues. If people buy them and can not deal with the interface (and price), the sales for the manufacturer will suffer. That is rather important to ongoing projects with the offshore manufacturer. They have to make money. Two or more versions can be a significant advantage to the manufacturer. They have a price/performance range. It also determines the future willingness to deal with this sites projects.

Using the Q8 (I own several) as an example. In my opinion (from several experiments) the interface for untrained users is quite hostile. Alternate views of this are completely useless, but widely propagated. Using multiple test persons, regardless of what the designers and (skilled) web site users say, numerous people explain the interface as simple, it just needs to be understood/learned. Others view the interface as incomprehensible. There is a serious dejvue element here.

Asking the potential lantern buyers what they consider important would provide guidance to the development team. Again, I have not gone through and counted everyone’s wish list. Assigning a projected price (or impacts on other features) for the various build decisions in the poll would help map the buyer base into more understandable desires/requirements. It is not too late to do this. But there is a high probability of no one paying attention. I keep getting chastised for not seeing/understanding the “correct” configuration. The control of the design, if I understand correctly, is in the hands of a relatively small group. They are absolutely essential. No argument there. But do they serve the masses or their excitement about bells and whistles? I do understand the basis of the web site thread and the anticipated configuration. But configuration has become complicated for civilians.

IT IS A LANTERN should be a battle cry of the relatively unknowledgeable people lining up for the lights (yeah, they are lights).

If it is something you would like to investigate, it could be discussed via private message with people who responded. However, the public BLF Lantern thread is probably not a good place for that discussion.

The lantern design is mostly based on DBSAR’s extensive experience with long periods spent off-grid, using a wide variety of lanterns, with feedback from others who have similar needs. Some details are also based on feedback from BLF, CPF, Reddit, IRC, and at least two manufacturers. So… many people have already been consulted about what they consider important. The research phase of the project is mostly done, much of the development is complete, and now the priority is getting the product actually made.

Here below shows the shortened version of the lantern, based from Lexel’s modified drawing, with added knurling to the mid section. ( the battery tube can be the same exact one used for the Sofirn Q8 if that saves cost/price per unit, and eliminate the four flat spots ( like the Sofirn Q8) as the flat sections is not needed.

The flats section look good to me it can reduce some weight and also have the logo on it if the mid section is knurling.

OK. My views on everything.

There should be a substantial stainless steel connection for a three leg stand. The hole for the tripod must have a complete water barrier internally. With no possibility of being penetrated/destroyed by a long attachment screw. Is making a tripod for the lantern being considered? The Q8 version of the bottom cap may not be strong enough for holding a small tripod in a center hole. The lamp will be tipped over, and worse. This is a potential weak point. If making a tripod, be sure you look at the leg spread required to minimize tipping the vertical mass, and uneven surfaces.

Flats bad; knurled good. No apparent reason to have flats except possibly around the control button.

Sloped plastic surround; maybe not so good. It could be done with a standard piece of plastic tubing; lower cost. Perhaps more durable/scratch resistant than the current selection. Top heat sink could possibly get smaller diameter but thicker heat sink/more fins if needed. The overall heat management needs to consider a range of environmental conditions. Is it zero F or 100 F? Both could be possible. Straight tubing would make it simpler to apply a removable shield to mask some areas of light. Much easier to find a replacement in case of damage.

Battery carriers have some significant merit. No carriers and extension tubes are one of the few things I did not like in my Q8s. First, the newer battery formats need to be accommodated. I have seen little preparation for new formats. Preferably using inserts in the carriers for the 18650s. In a year or two, we will be saying “Why on earth did we not consider the new battery formats that are replacing 18650s”. The carriers with extension tubes could double or triple the run time of the lamp even with just 18650s. I bought a TK75 for this feature. At bedside it has a 1 segment tube. In the closet is a tube for 3 carriers with charged batteries sitting with the tube. The sizing for the tripod would need to be designed to control tipping with a new center of gravity.

I do not believe it is reasonable to include external charging, charging phones, or jump starting your SUV. Anything not directly connected to it being a lamp. There should be a thoroughly sealed control button penetrating the shell; no additional holes in the shell using “stick in” sealing (none when doing external functions in the rain). I have multiple devices (phones, radios, etc.) where these little rubber plugs have shown their inability to work over time, or still be attached after some use (and just normal infrequent use). I think most people will use these lights in two ways. Emergency lighting; camping. I do not see many people wandering around holding up a lantern rather than a flashlight.

Using/charging the batteries in the lamp should not be a feature. There are many many inexpensive and compact external battery packs to charge your phones. Not to mention your vehicle. Why suck run time from the lamp. IT IS A LAMP. Not a source of getting power to watch a program you just can’t miss.

If we absolutely need to have these, I would want the type C connectors. It is where we are going. Using another version of USB or other protocols is just stupid. For a few dollars you can get a cable for the type C. There is no reasonable way you can fix the lantern if it is not type C. It boils down to type C now with an adapter (if needed), or adapters for all your nice new stuff.

Efficiency of the lamp should be the number one electronic priority. Whatever electronics are used; this should be the absolute guiding objective. IT IS A LAMP.

I do not view radiation frequency variations as a useful addition. I can live with it, if it does not reduce run time or increase cost. Otherwise, over a rather long time, I have been exposed to all of the visible spectrum (think walking outside on a sunny day). Some bands in the visible spectrum I like more than others. But I JUST DON’T CARE IN A PORTABLE LAMP. If there is no cost or loss of lighting efficiency for variable spectrum; OK. Otherwise no; IT IS A LAMP.

Probably best if you don’t buy this lantern.

eeeeeeeeeeeeeeeeerm nope…. This is not the lantern you are looking for! (say is with a hint of jedi)

if it don’t add cost per unit, then we can still have them like the original Q8 has. The logo will probably be etched around the head or just below the mid section knurling.

Current design Specifications for the BLF LT1 Lantern will be close to these below:

-Specifications:
- uses up to four button-top 18650 LiIon cells (in parallel configuration) Driver based from Lexel, Firmware from Toykeeper (LT1-Anduril)
- 150mm tall x 57mm wide
- Lighted electronic switch, (same as Q8 but with amber or yellow LED.
- USB charging, (either USB-micro, preferably newer USB-C input
- USB Power-bank charging out port, (up to 2.1 minimum continuous Amps for smartphones or tablet charging)
- down-firing LED design, with four Samsung LH351D 2700K high-CRI LEDs, and four Samsung LH351D 5000K High CRI LEDs.
- Tint range from 2700 up to 5000K with Tint ramping feature.
- between 700 to 900 lumens on maximum mode.
- Ability to run lantern on the lower modes while charging from a minimum of 10 watt solar panel) (able to sustain a minimum of 1 amp charging rate.
- up to 1.75 amps at the four cells combined on maximum draw, on maximum mode.
- minimum water resistant of a IP67 / IPX7 rating
- electronic & mechanical lock out. (Mechanical by loosening battery tube
- 1/4”-20 tripod mount on bottom for use as a raised lantern on a tripod.
- 1/4”-20 tripod mount on back of lantern, same as Q8 (for accessory reflector)
- steel loops on head for addition of para cord Lanyard( or one included with the lantern)
- 20% lens frosting (or frosted internal sleeve) for smoother light, but not reduce the output no lower than 5% of bare LEDs.

– Up-coming available accessory kit will include:
> white durable plastic directional reflector, (covers 40% of one side of the lens increasing light in one direction.)
>plastic snap on wide base cap for more stability (similar to the ones used for the propane gas Coleman lanterns for stability)
> long 12 foot USB charge cable (for remote Solar charging)
> padded woven storage sleeve storage case.
> upper “wide-hat” plastic white hood brim/reflector for increasing light downward when hanging above outdoors.
