Ok. After months and months of following this thread, you’ve lured me in. Please add me to the list of interested light enthusiast that hide they’re hobby from their wives. Wink

This is one of my least worrisome justifications to my wife. We haven’t lately, butt we have had many outings that would have benefited from this project.

Once Lexel gets the driver prototypes built & sent to Toykeeper to tesat with the firmware, then to send one to Barry at Sofirn to test and finishing working on the first lantern prototype to get it rolling. ( i hope.

I’ve, unfortunately, discovered BLF. This is not good…not good at all.
Please add me to the list of those likely to buy the ULF…(I haven’t even told my wife about the Taser Strikelight (hey, it was 25% off!) and I’m already modifying it…

It’s a pretty terrible affliction. My sympathies.

I have not tested the original prototypes on a single 18650 for run times, though they run on 1 battery just fine.

On 1×18650, the runtimes are 1/4th as long as with 4×18650. It is a consistent ratio. If you know the runtime with 4 cells, you also know the runtime with 1, 2, or 3 cells. Just multiply by 0.25, 0.50, or 0.75.

Very true, which will be determined once we can get a production prototype to test each of the stepped modes using good brand name cells. Right now i have not really tested the V2 with its current set up & amp-drain at the different modes, but the V1 was tested to run well past 12 hours on maximum mode on four good cells.

I will commit to buying two (total) of these.

Has price been discussed, and I missed it?

We could increase that to 40 hours on max by removing all but one chip on each power channel. Wink

This lantern could make good use of the Sofirn Q8 extension tubes if designed to fit. Imagine having the lantern fueled with 8 or more 3500mAh cells. Runtime for ever

I do wonder how it would behave on a tripod though.

Would make it a very nice night table lamp Smile

I had not seen that someone was doing extension tubes (I think). That is a very good thing .I have a Fenix TK75 with three extension tubes. Excessively expensive at the time, but a good light. The first set of 4 batteries is “regular” bedside. The next three sets are sitting (charged) in the closet for when really bad crap has happened. I had hoped the Q8 would have extension tubes; but it did not. This is good news for the lantern and the Q8 if available. I am primarily an emergency light person. We have earthquakes, bad storms, Tsunamis, occasional tornadoes, and forest fires. We don’t have immediately active volcanoes; but there are several in the area. Think Mount St. Helens.

Attention would need to deal with vertical stability with multiple extension tubes. A good stand would fix that.

I continue to want some of these lanterns.

Will those driver boards be sold separately in your driver sales thread too, for some who might want to mod their existing Q8 lights or other SRK-style lights?

EDIT: I just noticed your (re)programming pads are there, which is cool. But, looking closer, they are interfering with the ATtiny footprint, or rather the ATtiny footprint is interfering with the (re)programming pads.

There is a picture with 8 extension tubes. That makes 32 cells Wink
