I am soooooo IN!!

Interested in ONE lantern. Two, depending on the final price.

Thank you to everyone involved for all the hard work and dedication (and for feeding my light addiction)

And DBSAR: Get better soon…and thank you for all you’ve done for this project.

That’s exactly my problem. I really wouldn’t mind paying extra for power bank functionality but at the same time I don’t really need 2 lanterns (not sure if I need it at all but that’s totally different topic). Good thing it’s not ordering time yet so I should have enough time to thing about it!

I thought about this and the USB port problem

It may sound strange but why not simply produce v1 lantern body
- with USB micro and C port on the same aux board just wired in parallel below one silicone cover
And then in V2 this aux usb board gets replaced with new driver

So the upgrade would only need 3 LED wires soldered and likely a Thermal resistor with 2 wires for precise thermal regulation

So… Are you talking about a possible manufacturing design change or a possible after-market mod for those who could accomplish it?

It would be at least great if its possible to upgrade v1 lantern later to v2 with a kit

That would be a fun little mod for those interested.

It would, but it’d be even nicer to get the lantern out before CNY shuts down China for a month.

Making the hardware theoretically forward-upgradeable might be nice for the handful of people who would bother, but shipping before CNY is something which would benefit everyone. So I would only attempt it if it won’t cause delays.

Count me in for 1, possibly 2?

It all started with just one flashlight.

That does make a lot of sense, what is even more important it would make the V2, esentially the groundwork would be laid already.

I just don’t understand having both micro and C ports on the board. Wouldn’t one C port be enough to serve as a charging port and powerbank out?

For the emitters, you might want to consider the Oslon Square 2700k 96CRI. The tint is absolutely gorgeous for the color temperature. No yellow/green. The one sold on Ebay is a slightly rosy 6U tint bin and a high flux bin for the CCT and CRI.

Additionally, E21A 9080 tint mixing would be a really good option.

For Oslon Square high CRI leds the tint bins must be monitored closely, I had many green leds from RS components an Mouser before.

We may have to consider that option, as we discovered the Samsung 351 series LED are hard to order by the manufacturer. If Olson makes them in both 2700K & 5000K with the same foot print as the 219, XP-L, etc. that would be perfect as long as they are more efficient Lumens-per-watt than the 219 series.

Definitely want to avoid any greenish tints.

You just need to buy the right tint bin. The 6U is a really nice tint bin. No green at all.

Djozz and DBSAR, if you want, I can mail you a few pieces to test.

You’re right, it’s gone. The link now leads to a similar but inferior product. For the lantern project if interested, Sofirn can contact the Ebay seller or maybe even Oslon directly to see if they can source more of the 6U tint with MQ flux bin.

That would be great to test for the BLF lantern project. (as were discovering the Samsung 351 series is harder to order apparently that the manufacturer was telling us, and need to find a good replacement LED type that has good efficiency & tints for lantern use. (send me a DM for more info)
