Those are prototypes with color test bodies. They are not the production colors we are all waiting for. At that price, I’m waiting for real production units at the GB price.
Default 5x7135 configuration resulted in:
355 lm at WW
463 lm at CW
Tint and CRI measured directly in front of the LT1, but the results aren’t meaningfully different integrated, which means the diffuser is doing its job
Just curious, who have used their first bought LT1 lantern now in a power outage, on camping, or any emergency needing a long-running, great tint, high CRI, 360-degree light source where no electricity is available?
I have used mine every night since receiving. Mostly on level 2. I somehow made it in the 1st shipment even though I was a little past 500 on the list.
So somewhere around a month of use and charged it only twice if remembering correctly.
Been living in my van since last divorce. Will buy another place some day but it’s a great feeling for now not having all the bill’s and upkeep to pay for.
Loving the LT1 adjustable tint and ease of charging. Deciding to order my others now or wait for other color and upgraded firmware later.
With no batteries connected the buck converter on mine makes a horrible screechy noise on input voltages higher than 5V. On stepped level 2/5 it makes it at 5V as well. With batteries in and charging, there’s no noise.
Doesn’t really work for running from a 12V source without batteries then.
With a 12V input and the batteries disconnected my first batch unit does the same. Horrible squealing. So it’s probably not a bad inductor.
Wasn’t the ability to run without the batteries attached “discovered” as an accidental feature? So if this use case wasn’t designed for, it’s not really a concern for me.
It does work happily at 5V like this with no noise, so I’m considering it a bonus feature. This lantern does everything I’ve wanted for a long time. DBSAR, Lexel, TK and the team really knocked it out of the park on this one.
I just flashed the anduril.2019-11-29b.blf-lantern.hex on my unit, because it went into kernel panic strobe mode more often than I cared for, and ToyKeeper said this should improve that.
But I used the Emisar pogo pin while holding another wire for the reset pin, and hitting enter on AVRDude with my third hand. Needless to say that was less than fun.
Does anyone sell the HQ Universal Driver Programming Key already assembled? I don’t have a reflow oven and soldering the pogo pins to the PCB is not my kind of fun either.
I’ve googled the tar out of this and can’t find a US source for any pre-assembled Lexel driver compatible pogo key. TIA for any help!
Yes, indeed the ability to run with no batteries was an accidental, but great usable feature. :+1: The inductor begins to oscillate at high audible frequencies past 6 volts, but at the standard USB 5-volt input its silent. a low cost 12 volt to 5-volt USB adapter fixes the noise issue for anyone wanting to run it directly from 12 volts. I have test run the first production unit i bought for 5 days/24 hours non-stop on mode-3 of the stepped settings using a 5 volt USB wall adapter. it stayed quiet as a mouse.
I have a first batch lantern. I get the inductor whine when I have tried it connected to power supply without batteries. Its completely silent on battery power though. I use it every night as a lamp alternative in my office. Works flawlessly. I have charged it fully one (1) time since I received it. Really is a fuel miser in my experience. Can’t thank the team enough! I was on the list for two lanterns. Getting my second one now with code sent by Sofirn. Awesome lanterns!
Watch out with buying multiple lanterns with one code as you only get discount for first lantern. I bought two and only had the first one at group buy price. This happen to anyone else?
