- ( remember the head of the lantern is a heavy solid block of aluminum, much bigger than most single 18650 flashlights could ever have)
Have you considered adding some deep cooling fins in the top piece? This would have two benefits. It would remove weight from the top making it more stable when its set down, and it would increase the passive cooling when left on high for long periods.
good point, the fins could be machined in top edge. i will add that to the drawing blueprint design.

In a good momentary button driver the standby current can be a few uA, way below self discharge. 10 uA would theoretically take 100 years to deplete 4*2200 mAh.
Also you could try applying d-c-fix diffuser film.
Also some kind of battery indicator would be nice.
Maybe consider XM-L2 for its lower voltage, it’ll stay in regulation longer.

Very true, 10uA is almost nearly an open circuit compared to some momentary-on factory flashlights. You would be the good candidate to program or design a driver design for this that incorporates a battery-level function, which would be a great feature.
Right now it has a XP-L 7A3, but do have a XM-L 7A2 3200K that will go in the lantern soon for more tests & photos.

I will be giving this prototype a good field test on our big back country Canoe camping trip coming up next month we do every year in May. I will have beam photos, comparison photos, etc. also LED tint comparisons & feedback from the other campers in our group on the SRK/BLF lantern’s performance compared to others we will have. Once the tests are done i will post up a rough Blueprint drawing of the lantern design with specs that we can discuss to possible improve or alter before a possible production model can be discussed with Kronos

I’m interested. My biggest complaint with most lanterns is the cool tint which is not comfortable on my eyes.
very true, nearly 95% of all LED lanterns found today from stores have eye-searing glarey blueish cold tints. This lantern project has a nice warm white like an incandescent lamp.

Definitely Interested – Awaiting final specs and cost!
Thank You DBSAR for using your MADMOD Passion and for sharing this exciting idea.
Some outdoor photos will come soon this week of this prototype before its big back-country remote camping trip field-test in May, with feedback from fellow campers, & comparisons to my other best modified lanterns in use.
Then the design specs and blueprint design will be submitted for Krono & others to work on getting a production model rolling.

I’m certainly interested. I have a few lanterns but they pretty much all suck.
Good idea.
I am interested.
Sorry for my bad English (gogole transtorla)
I am interested too.
Thanks for sharing us!

It would be nice to have a lantern that wasn’t terrible. I’m interested.
How would this compare to the Fenix CL30R? Uses 3 18650s, 5hrs+ at 600 lumens.
Is there a rough estimate of the output/runtime of this lantern?
I am in.
This sounds interesting! I was just looking for a good lantern…. Count me in!
I am very interested!! Love where you are going with this one!
Interested, but gotta read up more on what’s goin on with it – just found out bout it.

TAKE ME WITH YOU!
A field test! Send pics. Sounds amasing!
I’m interested. Subscribed.

Make sure to include some photos of the canoes Den!
Enjoying this thread and looking forward to seeing how your new creation performs.
Nothin better than canoeing with the family

Interested, maybe I’m blind but do we have an idea of price yet?
Were not to that stage yet. (pricing)
That Canadian flashlight guy & Lantern Guru -Den / DBSARlight
Gotcha. Who will manufacturer the lights? Sorry tl;dr
We do not know as of yet, that will depend on who Kronological can work it out with.
