I have one similar for my Tribit speaker. Cost me about $8/£5.

Nice idea as it is, I can’t see a GB benefitting anyone, the postage costs on from the receiver to those wanting a case would be too expensive, not to mention possible postage problems caused by Covid-19.

However, I’ve noticed that even if I haven’t used the LT1 all day, when I turn out the lights the diffuser appears to glow slightly.

Does it continue to glow if you unscrew the battery tube from the head. That should eliminate if it is caused by some sort of an electrical leak causing the glow or something that glows without power.

I have a question... The answer has to be somewhere in the thread, but I can't seem to find it.

The LT1 lantern, by default is configured for 5x7135 (1.8Amps), but can be configured as 6x7135 or 7x7135 (max, ~2.5Amps), by soldering the joint points for each solder point on the driver board. I forgot whether it was also possible to reduce the max power (3x7135 or 4x7135), by desoldering the points marked "5" and "4"?

I notice on the rev 5.0 board, the "5" and "4" appear to be linked by electronic circuit trace.. so it means reducing the power is possible on the older batch but not as easy on the newer batch?

The latest batch are designed to support USB C to C charging, but I haven’t actually seen it confirmed here by someone who owns one yet.

Well that sucks I ordered a 3rd batch lantern and type c to type c did not work. It would not surprise me if sofirn has sent me a earlier model as I feel they do not ship on a first come first serve basis

Borrowing d_t_a’s picture:

The driver on the right (the rev 5.0 one) has two resistors near its left edge, labelled R_CC1 and R_CC2. Those enable USB-C to USB-C charging. If your driver doesn’t have those resistors, then you’ve been sent an older version LT1.

Ok this is weird but apparently I do have a 5.0 version but it will only allow me to charge the lantern via my phone but it will not charge my phone. So in essence the type c to type c does work lol

Sorted. That’s the way it’s supposed to work. The LT1 is only designed to accept power from an external power source, so it can charge itself up. It can’t provide power to another device.

One day, there might be an “LT1 Deluxe”, with a powerbank function that can provide power to another device, but that’s a long way away, if ever.

Thank you for confirming that the new LT1 does charge from a USB-C charger – now we know for sure that the rev 5.0 driver upgrade works as planned Thumbs Up

Just ordered mine with the kit and the case. The description mentioned “latest version” so hope to get the latest with usb-C to C charging. Will be my first lantern\soda can style light.

As the others above mentioned, the rev 5.0 board does allow type-C-to-type-C charging (charging the LT1 lantern, but not the lantern as a powerbank)

Aha. Therefore, resistance is not futile!

I got my LT1 a week ago. Bought in sofirnlight, in Russia the package reached in 35 days I consider it a very good result. Tremendous lamp! Latest version, 5.0. I use it every day, it ‘s like a toy, I ‘m really happy.

Has anyone tried bridging the drivers 6 and 7 to increase the max brightness by using pencil? Can anyone can show the picture of how it’s done? I’ve done it but not sure if I did it correctly as the brightness isn’t noticiably different. And I measured the lux by using my phone and I got more lux at mid CCTs than at 5K CCTs. Is that normal?

I’m interested in getting 2 or 3 of these. I’ve been aware of the project but I have to admit I haven’t followed it very closely. What is currently the best way to get these?
