Put me down for one please.

Interested - 1

1008

Interested in 1

1009

One for me too.

1010

Also interested in on (1) light.

I like where this is going so far, especially when there is a true WW option.
Camping light = warm light.
At least to me that isā€¦

Same here, I never understood folks that spend their evening outside with a cool white neon Coleman lantern. :confounded:

1012

Iā€™m in!

Had a situation where this light would have been the perfect solution

1013

Please add me to the list for 1, this souds too good to pass up.

1014

Interested in one.

Thanks.

1015

I read on another thread that the lantern project is going for about 500 lumens on max. Is this true? I would imagine that this might be about the highest output that I would need much of time, but it sure would be nice to have access to a higher turbo level for those times where more light is needed.

1016

Really nice project!

Please add me for one.

Thanks. :slight_smile:

As far as Iā€™m aware, yes.

The driver is using true current regulation, not a FET+7135 design, and all MCU pins are already being usedā€¦ so increasing maximum output is not very feasible without significant design changes.

Itā€™s designed by someone who uses lanterns frequently for long periods, to be practical rather than flashy. Ideally, charge-able each day with a small solar panel, with enough runtime to last the entire evening, for long-term off-grid use.

I have a 650lm Fenix CL30R. I never use it on high, its just too bright for around the campsite.

1019

I will take one as well.

1020

Agreed on warm light.

1021

I sure hope itā€™s a lot more than 500 lumens, that isnā€™t much for times where youā€™re trying to light up a decent sized camp. That said, when itā€™s pitch black out, your eyes adjust pretty well to lower light levels.

1022

I have not measured it for lumens accurately, but it is the second brightest LED lantern i have (out of dozens of modded ones i built & modded) the problem is it can not be pushed to bright because of its compact size, ( there is not enough heat-sinking metal to prevent it from over heating. Lanterns differ from flashlights in that lanterns run continuously for hours at a time. Even with just two 7135 chips, on high, (at .700 amps) after a hour running the solid aluminum heatsink top gets hot. When i ran it with three 7135s at 1.05 amps, it got to hot to hold ot touch after a hour. it produces more light output thana 40 watt Incandescent light bulb, to push it brighter woudl require a much larger finned top heatsink. (thus it wonā€™t be pocket-sized anymore.

1023

I am actually not sure what 500 lumens from this lantern will look like. I am sure that it will be more than enough for campfires and cat fishing on the riverbank. If I need more light I will use more than one lantern. :slight_smile:

1024

Will the lantern collapse when not in use? Or will you have to pack all that space with it?

1025

no. (I donā€™t see how it would be possible to collapse a beer-can sized lantern with 4 18659 cells in it, would drive the price up to high.
