I’m sure this question was asked somewhere in the last 130 pages but will flat top cells work ok?

Like the BLF Q8, it will require button tops.

Would you recommend protected cells? I was thinking of using protected NCR18650GA’s.

Does the lantern have some type of colored lights when voltage gets lower such as 4.2v green, 3.8v orange, 3.6v red or something like that?

Not that i’m aware of, but woudl be a good feature. The firmware was developed by Toykeeper , and driver design by Lexel.

With Lexel and TK involved, there's a good chance there is something like that built in already.

I imagine the firmware will be a version of Anduril, which does have a voltage check feature. Three clicks from off, and you get the voltage blinked out. 4.1V is four blinks, pause, one blink.

The features are really amazing. This will be my first quality led lantern and between the tint mixing and the way you designed the “beam” I don’t think that I will go back to my gas powered ones.

I think this is the first really “quality” production LED lantern, period. It will be a first for most of us.

Superb. Any idea on when this will be available?

before Christmas, like on all BLF developments.
It depends on the quality and function of the production sampel. After that it depends on production capacities. No one can say when they are ready for sale.

Protected or non-protected cells will work fine. (the driver will have low voltage warning built in.) just make sure the four cells are the same type, same capacity & matching. The solder mod can be used to make flat tops work too.

@teacher

That looks great DBSAR!! :+1:

Is there an O-ring or seal where the bottom of the globe meets the body?

Yep, o-rings are planned on both the top & bottom of the globe lens to seal water out.

[EcuBebge]

In for one lantern please.

[DBSAR]

The test samples are ready to ship to us for testing & evaluations.

[BlueSwordM]

Wait, why 4 samples? I know Toykeeper and you will have them, but who else?

Also, what LEDs are being used?

Barry is keeping a couple for them to test themselves. 2700K & 5000K, high CRI, right now as far as i know they used the easiest to get in High CRI, SST20 2700K 95 CRI, and Nichia 219C 5000K High CRI.

Edit: Barry just informed me they used Samsung LH351D emitters for the test prototypes.

They probably have learned from the SP36, they made 2 prototypes and one was sent to me and the other to ToyKeeper, and then they had none left themselves. They could not even make pics in time for the website

[2Grumpy]

Please put me on the interest list for 2.

This is a great project!

[sbslider]

This is super exciting. Seeing the video and pictures yesterday was nice, but I still wondered how long before others would get their hands on them to check out. I’m very glad TK will be getting one to finalize the firmware.

[Yourrid]

I’ve been following this for a while now, and finally getting to see a prototype is so awesome! I’m getting the itch to go camping now!

I am also a gas lantern collector & builder! meaning i have done many comparisons & developed this LT1 LED lantern to stand & run with the gas lanterns. ( here is a few of my restored vintage gas lanterns.

I have a few but your collection is just epic.

[DBSAR]

Barry just informed me they found & used Samsung LH351D High CRI emitters for the test prototypes.

[BlueSwordM]

Wait, LH351D 2700k and 5000k 90CRI?

Yeaaaahhh nice.
