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!!
the prototype under construction, though been over busy at work the last few weeks to do much progress on it, but i hope to get it ready by end of April. 
I’m interested 
Exciting! Just don’t post it April first 
lol i may stay away from the computer on April 1st
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!
I need a new shed light.
I’m in…
it is starting to itch to see what is gong on, so if you do have input, please post is, even on April 1st
More progress updates on the BLF Lantern project in the lower part of the OP on the first page!
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!
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)
More progress updates on the BLF Lantern project in the lower part of the OP on the first page! now with first Beamshot test photos indoors! / April,3,2016
- and still running on maximum mode. (6.5 hours and counting) I will have to shut it off soon as i can’t stay awake all night to monitor its run time progress. (then restart it tomorrow evening)
I am discovering however the constant running temperature of the XP-L 7A3 on the head at maximum mode has been holding at a constant 44.3 degrees Celsius for the last 6 hours. (running at a constant average of 1.1 amps measured with the three-7135 QLite driver.) ( See IMAGE below:)
- This temperature to an adult hand feels very wrm, ( borderline hot) but if a child touches it may feel to hot) this confirms that with the XP-L it is at its peak running amps versus efficiency for this application, ( remember the head of the lantern is a heavy solid block of aluminum, much bigger than most single 18650 flashlights could ever have) so if a modded driver of higher amperage is used an additional heatsink may be required.
But in this prototype lantern its a good balance of output vs. amps draw vs. heat dissipation for lantern use.
Got to love a GB!
Count me in!
