I understand your point completly, but this isnāt a charger, itās a lantern with charging capabilities. I think the end charge voltage is dependent on the chip used, so I gues itāll be a lottery as to which voltage your specific lantern charges. I donāt think the team can do anything about it. If you or I want 4.2V exactly Iād charge my cells ith a decent quality charger and use the usb charging for when Iām out camping.
Iām fine with either head, size wise, but I do have a couple of questions:
whether the white translucent plastic of the new sample head - as compared to the frosted clear plastic of the old prototype head - might affect the CRI of the light passing through it? The new sample headās diffuser looks white to the eye, but it would be a bit of a bummer if white filler in the plastic happened to disproportionately absorb some crucial wavelengthā¦
whether the larger new sample head might have a slightly wider-angle spread of light upward and downward compared to the smaller old prototype one? The reason that occurs to me is that the new sample headās diffuser seems to sit closer to the edge of the metal above and below it, so thereās less of a lip that might intercept some light.
I will be asking then to reduce the opacity of the frosting of the globe/lens. As less frosting will not affect the CRI as much, and will also allow more lumens through, (a double bonus) I will list the changes soon to the production one over the test unit.
indeed the test unit lens is closer to the edges of the head and the mid section, which i like as it reduces any edge shadows and increases the illuminance angle directions.
There is a specification list posted in the OP, but for the operation of the firmware of the lanternās modes, our team member Toykeeper is developing a LT1 lantern version of the Andruil software, (and should be a full schematic of the operation soon of the finalized production of the lantern user-interface.
The user interface will be similar to the first item in the linked post. What that does not show is the tint mixing commands. Also, that light is based on a single 7135 regulator plus a FET driver. The driver for the lantern is several 7135s, so the output is always regulated to the set level.
Great job on the video DBSAR. It was nice to see and here you describe the features.
The lantern is looking very good, really looking forward to gifting a couple to my sons.
These are the additions since last Sunday. Count is 1509 as of tonight.
Donāt forget to check that your BLF user name is valid on either one of the Excel spreadsheets linked in post #1. If your name is not correct then you need to send me a PM with the correct spelling otherwise you wonāt be getting a PM when the buy goes live.
you may add a 0.1F supercap to the driver which is more than enough to sustan the bumps and also funftion with no battery
anyway a alntern is not meant to bump around much
Fireflies tested a 100uF cap added to C2 and it does not work good reducing bumps shutting the light off
Anduril can be flashed that it comes after a bump on last memorized leven, which will work well, the question is if we want this on the stock light or not
It depends. Myself I camp in 3 styles.
I often arrive by car and spend time in a tent - then size and volume are or secondary concern.
Or I travel with backpack, sometimes by foot. Then size and weight are critical, LT1 is surely too large.
Thereās also one yearly event where I travel by car but leave it several km from the tent. Then size and weight matter but are not critical.
Overallā¦I like compactness. But I donāt really care much as LT1 is already quite big and heavy.
I assume that the final version will not have lantern-useless modes like āmomentaryā and ābicycle strobeā, but do we know yet whether it will contain the candle, sleep timer, lightning storm, etc?
Those modes may be useless for a lantern, but it makes me think that it would be useful to have a mode to attract attention in an emergency with long run-time. Whether thatās ā¦ - - - ā¦ or something else, there are probably others here more qualified.
Itās not the exact LEDs the lantern will have but it should be a ballpark number for when both channels are at āmaxā. This is a good result and lands very close to BBL.
