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

Both v1 and v2 come with USB-A to USB-C cable.

from what I observe:

version 1 (board revision 4.3):
- charging works with USB-A to USB-C cable, but not USB-C-to-USB-C cable
- the solder points 4 & 5 appear to be manually soldered (can unsolder to reduce max brightness)
- slightly earlier Anduril version

version 2 (board revision 5.0):
- charging works with USB-A to USB-C, and also USB-C-to-USB-C cable ; this is because a tiny resistor has been soldered near the charging port portion to allow USB-C-to-USB-C to work
- the solder points 4 & 5 appear to be jumpered already internally (I think will need to break that jumper to have reduced max brightness) <= I'm not very sure about this part though..
- a bit later Anduril version (2020-03-18 or 2020-06-02) ; it's noted by Lux Perpetua that they may use Anduril 2 in the future - not sure if the board would still be the same -- I have already flashed my LT1 to Anduril 2...

I notice the position of the "loc. LED" label on the board changes from v4.3 to v5.0 = not sure if it's just the label position move or there is any change.

Yes same :innocent:

good idea. I would buy 2

Received my Orange LT1, ordered from the Sofirn Aliexpress store. Amazing super quick 10 days delivery to Australia (never had an Aliexpress shipment that quick!).

Unit is certainly nice and solid, feels very well built in the hand.

A small blotch of one-two diamonds of the knurling are missing the orange anodizing, but otherwise the finish is really nice.

Ordered the kit version so it included the Sofirn batteries, and unfortunately one of the batteries had a very sharp edge on the top nipple. The result of this was every time you unscrew the batteries, you would get a pile of metal shavings from the battery cutting a groove in the contact ring on the board. Thankfully I noticed that quite quickly and a minute with a jewelers file solved that issue, as having metal filings shaking around near the driver board may not have ended well.

What glue have people used to attach the top o-ring, as I see that pops off really easily?

The UI certainly is very “comprehensive”, but seems easy enough to just use the simple on/off, brightness up/down without using Muggle mode.

Congrats to DBSAR and others for all the work in producing this lantern. Certainly glad I bought this instead of the CL30R I was originally looking at to compliment by CL25R.

I have the same problem with my batteries, I made a post about it to warn people. I tried to tell Barry but he said its not a problem :person_facepalming:

Edit: I guess he didn’t understand what I was saying when I messaged him but they see the problem now I think.

Welcome to the forum GMozz.

I moved the orange O-ring down on the light to the slot just above the lighted switch for decoration (where it cannot pop off anymore) and purchased some Youth/7" sized Silicone Rubber Wrist Bands (which are 1/2" wide and do not pop off unexpectedly like the orange O-ring) from AmazonUS to use at the top of my LT1 lanterns as a bumper for some limited extra protection in case the light trips over on it's side, but you may be able to find something similar in Australia.

I purchased the "Black" color which looks elegant on the light, but they have many colors to choose from including "Green Glow in Dark". I'm not sure which size fits best (Youth/7" or Adult/8") but the Youth/7" size seems to fit perfectly with just the right amount of stretch.

I just used a couple drops of superglue and the orings haven’t moved on my two lanterns. Hot glue might be cleaner in the event that you want to remove it.

This thread on Reddit describes the process using the Emisar flashing kit.

I’m really keen to try it myself but given the shipping cost I’m waiting to buy a Hank light before buying the flashing kit. If anyone can suggest an alternative flashing kit that’s a bit cheaper I would appreciate it.

I asked Barry a year ago about this. He thought it was a great idea, then, crickets. I even asked if I could buy a blank board to install my own emitters. He said sure, but never responded after that. I camp a lot in the summer, and red doesn’t attract bugs.

Anyone with the manual in PDF? Who should I contact from the company?

Does this help you?

Hi, the manual link is broken, can you share an updated one?

Thanks, the original manual is the one I’m looking for, I guess Lux can re-upload it.

Does anyone know if usb charging does balancing of the 18650 cells?
And why does the power button stay lit all the time? Doesn’t that consume battery when off?

Any updates on a 21700 LT2 version? :smiley:

The way the batteries are connected in parallel, there is no way to do any balancing, so definitely no.
Any configuration with an electronic switch will consume battery when off. An indicator or auxiliary LED will add to this. You can turn the LED off in the Anduril configuration if you want and it will reduce the parasitic drain, but not remove it completely. The only way to have absolutely no drain is to unscrew the battery tube a few revolutions. Not just until the button LED goes off, but more, to completely sever the connection of the batteries to the light.

The cells are in parallel so they will naturally self balance. No special considerations are required for balancing while charging.

The switch LED uses very little current (don’t remember exact numbers; it’s been mentioned before). It would take years to drain fully charged cells. If it’s a concern, it can be turned off.

I recall a calculation that the switch led would take 16yrs to drain the battery when set to low.

Now if you haven’t used the lantern in 16yrs…. well then the parasitic drain from the switch led is hardly the main concern.

When I first got my LT1 I unboxed it, tested it playing around for a night then put it away & didn’t use it for a few months. Now I use it every night. Run it without cells off a 30,000nAh Romoss power bank and attach lantern to a light weight collapsible stand.

Looking forward to the mini when its done.

What this CL1 lantern ive seen on facebook?
