Looks great, put me down for 1.
Iām only worried about the diffusing material. Looks too white instead of a frosted clear material (Like sticking DC fix to a clear lens). White semi translucid diffusers can degrade over time and turn the tint yellowish/greenish.
I just measured it, and the test unit is 6 Millimeters taller. ( 1/4ā inch)
Wow, I didnāt expect that much. Thank you for measurements.
Apologies for being slow, but now Iām really confused - is the plan 14x 7135 chips on the board in total (i.e. 7 per channel) or 7x7135 chips on the board? Also, Iām glad to hear that all 7 chips are going to be populated - I think my soldering skills are up to forming a solder bridge, but probably not up to sticking an extra chip onto a PCBā¦
Edit: Where are my manners?! Thank you to team LT1 - I am now ridiculously excited about this project. Thereās already so much incredible work that youāve put in, and Iām very grateful for it!
Oops, typo, i meant 6 millimeters. 
Right after your response I looked again at the pictures trying to figure what I didnāt get. My brain froze with confusionā¦how could it be 6 cm ?!? 
Ah yes, I remember we discussed about it in PMs.
All of the 14 7135s will be soldered in.
However, only 4 per channel will be activated at the same time.
I would love one. Thanks!
Thatās awesome that all the 7135s will be populated and that we just have to make solder bridges to bring the others āonlineā. Very smart and thoughtful of you all. 
Thatās what we are planning.
We are planning to limit power via firmware, with only 4x7135 per channel being activated initially.
Edit: See, this is what happens when Iām confused.
I donāt believe that is correct. The plan was to populate all 14 7135s (2 channels, 7 per channel), and allow folks to connect in additional ones by shorting pads. On the prototype all the pads came shorted. Like I think DBSAR said recently only 4 or 5 would be connected as āstockā.
correct, that is the original plan. Have 4 or 5 connected from the factory by default, and the rest left open for those who want to push more output at a sacrifice of run times. I will be testing the maximum run times & amp draw loads with all 7 connected at first, then desoldering a couple of the 7135 bridges on each channel to get amp readings and run time comparisons then. The extra AMC chips are to be on the board for user modifications. (increase in output)
Nope. The control chip doesnāt have the physical ability to activate individual 7135 chips.
There are two ways for the user to adjust the highest power level:
Today there has also been some discussion of a āturbo plusā which would only work at 4000K color temperatureā¦ but I wasnāt planning to add anything like that.
Please place me on the interest list.
Iām already on the list for two, 688 and 689. Please add two more for a total of four.
I plan to pick up 4 full sets: lantern, batteries, case, etc, etc.
The first two are mine. Mine mine mine. The new ones are planned gifts. Depending on overall price, I can see picking up a couple more than four.
Amazing work, thank you.
One side note. Iāve been going out to Burning Man since the late 90s and have rigged up a ton of led solutions over the years. Iām the ālight dudeā in our camp. This is exactly what Iāve been trying to make as far as a portable lantern goes. Iām not sure I want to be responsible for the possible carnage, but I think a post or three in BM forums would yield a great deal more initial orders. If thatās desired. At a risk of drastically lowering the S/N of this thread.
Iām interested in one.
There is no doubt this LT1 lantern can be a big interest outside for the general public eventually, as it fills a gap for a good quality area light/lantern that has recharability along with battery replacing, high CRI tint, functional design. portability, long-term off-grid uses, great modes, built out of metal (wont blow off the camp table like some plastic ones do i seen) the list goes on.
Awesome, thanks everyone! Man this is cool. Put me down for 2 more, for a total of 4 please.
On the note of bringing in burning man people, Iām torn. I donāt want to bring more noise into this thread, but I do want people to appreciate this light. Maybe sofirn would be happier with us if we let the BM people pay full price? That sounds mean and selfish now that I say it. But I kind of feel that way, anyone else?
Also, just my opinion, I donāt think we should have a turbo+ mode. I donāt think there and be any mode that can overheat the head of this lamp. Because there is no efficient way to get heat to the MCU, correct? People could burn themselves. Unless we added a turbo timer? Itād have to be real short.
Maybe make it a config option in the source code? People adventurous enough to compile their own code, or find someone to do it, can be trusted with the extra power. In my opinion. Iām just worried about the people I plan on gifting these to.
Yeah, I agree with BM people having to pay the full price.
We have to respect Sofirn, and BLF itself.
No arguments, thatās why I tossed it out for discussion.
If youāre going to BM and are even remotely interested in leds, then youāve most likely already found this place. If not, itāll be a pleasant surprise.
