*BLF LT1 Lantern Project) (updated Nov,17,2020)

Good idea.
I am interested.

I am interested too.
Thanks for sharing us!

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.

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.

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

TAKE ME WITH YOU!

A field test! Send pics. Sounds amasing!

I’m interested. Subscribed.

I’m interested. My biggest complaint with most lanterns is the cool tint which is not comfortable on my eyes.

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

Welcome to the Forum! :beer:

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.

Interested, maybe I’m blind but do we have an idea of price yet?
