Sounds good as long as it’s not too expensive.

Sounds interesting! I am interested.

Interested, depending on cost. I’ve been working on a “lid” light for a while, though much less powerful than this (two 18500s). Adafruit makes a stand alone Lith Ion/Li Poly micro USB charge board 3/4” square for 7 bucks. It’ll only push 500ma, but it’s self contained, affordable, available, and made here. Also, should it be of use to you, Nalgene 4 and 8 ounce polycarbonate straight wall jars have Mason threads on them (very close to the diameter you’re working with—2.625” thread OD and 2.52” jar ID). Stainless one piece Mason lids and silicone seals are available from Mason Lifestyle. I’m thinking that riveting a stainless lid to the base plate would be an easy and waterproof way to join the diffuser (if using the Nalgene jar) and body. Even better may be to cut mason threads in the aluminum housing itself and skip the lid, though the two may not work out diameter-wise.

This looks extremely promising. I’ll be in for at least one. If it had usb changing, it would definitely make it more appealing to the non-flash crowd and boost sales and gifting. Very cool, getrdun!!

I live in the mountains of East Tennessee, and with lots of trees and power lines, its not uncommon for power outages. I once went three days without power. I have a 6000kw generator, but you don’t run that for a light bulb. I’m interested for a few of these when finished. Thanks for all your work!

Suncoaster · 2016-03-31T04:11:40.000Z

I need a new shed light.
I’m in…

The_Miller · 2016-03-31T08:06:05.000Z

More progress updates on the BLF Lantern project in the lower part of the OP on the first page!

Cula · 2016-04-02T06:07:45.000Z

Looking good! Can’t wait to see this this thing light up. Keep up the good work. Could you add dates on your updates? It would be much easier to follow.

Good point. i will add dates to the OP.

Wauw! That build looks amazing!

Dirt · 2016-04-03T01:23:24.000Z

Nice progress! What kind of price point are you reaching for with this lantern? I can think of about 200 uses for this light.

The price of a production model will depend on the manufacturer who builds them, the seller, and what Kronos can work out with them once i have the protype completed, tested, and specifications on paper for the design based off this prototype.

Interested depending on final price, will be watching this thread.

XP-L 7A3 80 CRI is a nice led for a lantern, I have one of those in my brass CQG 18650 especially for camping.

The 7A3 is my favorite natural warm white tint for lantern use because of its near incandescent light. Its the least glarey of tints i have tested, and gives a candle-like glow on moonlight mode. (there are warmer tints available, but they seem to go to yellow)
my other favorite tint for Lantern use is the XM-L-V3 5D. its a 4000K neutral white with a very slight redish hue, much more pleasing to the eyes than the other 4K tints that have a greening hue.

Other honorable mentions for lantern tints go the 7A4, 8B4, 4C, & 3D (3D being the coolest tint i would ever put in a lantern)
