BLF/AI
Looks like artificial intelligence but it’s Area Illumination
I thought about Artificial Sun Shine but those three letters seem wrong when put together. :innocent:
I feel like I’d regret not getting a second one, so could I add my name again to the list please? I’m already on #431 for my first one.
xikteny is number 875 on the interest list, if the price is not right no obligation to buy one.
I hear you, I am on the list for 3. Your second lantern is number 876 on the interest list.
That second name would be more appropriate if the light had a $1000 price tag and fancy marketing about how it was handmade by virgin monks, with uniquely advanced quantum engineering inside, to cure all manner of physical, emotional, and spiritual ailments. Because then it would be pretty undeniable that we think the sun shines out of our, um, “Artificial Sun Shine”. 
(At least the part about quantum engineering would be true. All common computer chips rely on quantum mechanics in order to function, because that’s how transistors work.)
I’m sure Ultimate Camplighting Kit is out of the question… :innocent:
SkyLantern has grown on me. You could do one of those fancy logos with “BLF SL” and have a Chinese lantern in between. I tried to make one but I’m apparently… artistically challenged. 
That is the funniest thing I’ve read in a long time.
Not only are you the smartest person I currently know (as far as light goes)your eloquent writing and sense of humor could propel you into a successful comedy writer career or a stand up comedian.

LMAO!
2700K at the warm end tint would be great, worth losing a little output & efficiency to persevere circadian rhythm when sitting around the campfire but a little additional lighting is needed at night
if i only had the 2700K & 5000K to test, but right now i only have the 3000K & 4000K LH351 series LEDs to test.
TK is indeed a special person……… Ive thought of PMing her and telling her just that but then I thought, No, she would probably be more annoyed than impressed with any praise ……
Logo idea:
- Currently modifying the V1 Prototype lantern to run four LH351 3000K LEDs to do direct comparisons to the LH531 4000K LEDs that are in the V2 prototype now. I don’t have another Q8 MCPCB so i flowed the emitters on four 16mm Cree stars and will work with those to get the V1 as close to the pattern as the V2. (photos of comparisons coming soon.
These are 351Bs and not 351Ds though. The efficiency difference might be quite large, but still interested to see.
Interested
indeed, the die of the 351B is a bit smaller than the 351D 4000K. (i’m guessing like comparing the 119 Nichia to the 219 Nichia.) in this case its more of comparing the tint as these are the only two typs of 351 Samsung LEDs i have to test on this trip. (the 351D 3000K or 2700K high-CRI and the 351D 5000K high-CRI LEDs would be a good comparison for the tint ramp options.
Ok, here are the first photos comparing the 4000K Samsung 351D LEDs to the 3000K 351B LEDs. I modified the V1 of the lantern to use four LEDs the same as the V2 prototype uses, Because i only have the 351B 3000K versions, they are less efficient than the 351D versions, (They are sort of like comparing the 119 series Nichias to the 219 series, as the 351B has a smaller die than the 351Ds. So in this case i have to increase the amps to the LEDs to get the same brightness output. In the photos below, the 4000K High-CRI is on the left, and the 3000K High-CRI is on the right. ( images are gamma-corrected and adjusted to appear what the eyes see depending on your monitor settings)
The 4000K V2 on the left is on mode-4 at roughly 1-amp to the emitters, & the 3000K has roughly 1.3 amps to the emitters. (first photo is 1/320 shutter, F2.7, D5100 Nikon, second is 1/180 shutter, F2.7, D5100 Nikon) To the eye the 3000K has a very nice incandescent light tint, while the 4000K has a nice pure white tint slightly whiter than a good halogen.
Wow. I had not seen that 351B before. A pure warm white with a lot of reds.
Looks amazing.
indeed, i really like both these tints in these new Samsung 351 series LEDs. They are high CRI, and have a really pleasing tint, with much lower tint-shift that the Cree XP-L series has.
DAMN no want one of both emitters!!!
There is a good chance it will be able to change tint. So… it’ll probably have both emitters in one lantern.
Forget the lanterns, I want whatever the hell those brassy, steam-punky things are in the middle, they look awesome.
