Barry kindly sent me some real pictures of the new LT1 colors. I think their anodizing team did a pretty good job, didn't they? Maybe we get to see these new colors packed with new features like full USB-C compatibility (PD charging) as well as reverse-charging, i.e. to use LT1 as a powerbank to recharge external devices.

I really like that dark green. The other one just looks black on my monitor; how would you describe the color, Lux?

Looking good! – My apologies for my limited correspondence over the last number of months, been crazy busy with the big move, settling in a new house, all that. I hope to chat more with Barry soon on the colors versions, accessories, and the Mini LT1 once i get back on my feet.

I assume they’re just using what they’re familiar with. These look like the EC01/3 colours

On Sofirn’s own site they are selling the 2 colors above as well as the orange, but they did not provide a photo of what the orange one looks like.

https://sofirnlight.com/ – says it supports C to C charging, but when you click into the item link is still says A to C charging???

I didn’t know these could be operated connected to a wall charger without batteries. Will need to try with my updated version. I guess if they support C to C charging this would be version 3?

I’m assuming the Attiny85 doesn’t have enough pins/legs/whatever they’re called to support a third channel? I’ve been using my LT1 as a bedtime lamp in sunset mode and would prefer the lowest pwm mode to go a bit dimmer. I might just remove one of the 0 ohm resistors on my driver board but I was wondering if there’s the possibility of DIY-ing a single 7135 third channel.

Would something like disconnecting the switch and connecting a 7135 to that channel work or is that leg not a pwm possible leg? I wouldn’t mind having my switch just constantly dim and using the provided potentialometer to adjust the switch brightness.

@SR-G If you like ali, here’s the ones that match: https://www.aliexpress.com/wholesale?catId=0&initiative_id=SB_2021012412...

Another interesting option that can be used is the magnet with the Dslr 1/4 screw

Has anyone heard anything about the production of more orange LT-1s? Seems they’ve been out of stock a while and I haven’t gotten anything in reply from Sofirn except that they are out of stock.
Has anyone actually received an orange LT-1?

I ordered one while the sight said they were available, only to be told that they weren’t available. I waited 12 days and nothing shipped.
I finally asked sofirn to either refund my money or switch my order to a green lantern, which they sent yesterday. When I contacted Barry
he told me they were waiting on anodizing. Sounds like they were never really in stock.

I am waiting on an orange also. Sent them a message they said 20-days two days ago so 18-days now who’s counting

Thanks for the replies. I am wondering if perhaps they were mistakenly listed for sale prematurely as it is my understanding is that no one from the posts about orange LT-1s has seemed to actually have made it through the process to receiving one.

That would be great, here’s to hoping 2 days is the magic number

Here’s the thread about the colored versions:
https://budgetlightforum.com/node/69644

It would help others if the discussion about colored versions of the LT1 would be all in the dedicated thread Thumbs Up

Thanks, angerdan, I forgot about the color thread. I’ll post there as well. I had noticed there were posts over here where people had attempted to order some and had failed. This thread is a beast.

Is there anyone willing to try my custom 16 bit build of Anduril 2 for the LT1? I’d love to get some feedback on it.


It provides nice and smooth tint ramping and much less tint flickering when dimming at low modes, it’s just that the brightness curve is somehow bumpy and I haven’t figured out why yet (I actually suspect hardware non-linearities). I haven’t seen anyone else do this yet (faking 16 bit on an 8 bit capable MCU).


I can provide a zip with the source code and hex file to anyone interested (I still don’t understand how to add my code to TK’s firmware repository without considerable effort). 

Streamtronics has made a fantastic improvement to anduril 2 which allows for tint ramping at the lowest mode and he says it has the ability to make the dimmest mode even lower which I’m most excited about.

I was surprised that I was the first person who has tested out his version of anduril 2 and so far it has been terrific!

[quote=SR-G]Do you know which screws (with which dimensions) to buy and that would fit the BLT L1 screw holes ? I ordered these ones (flavor "LS047" / screw 4.5mm + additional height 3mm), and sadly they don't fit well (and not in the same way between hole on the side versus at the bottom = it goes deeper on the side) (and i haven't been able to find models without the "gap" in the middle).

 

Hi SR-G Just use a rubber washer to give you a good fit. Maybe something like a washing machine or dishwasher hose washer or a jumper valve washer. In the olden days, I used one on my camera tripod as the depth of the tripod screw hole varied from camera to camera.

So I’m in. What’s the best place to buy this ?

I have compared my LT1 to my Fenix CL30R and the fenix on turbo mode is quite alot more lumens than the LT1 sadly Sad
If the LT1 has those extra bridges soldered can it’s higher output stay sustained without overheating/having to step down?

Yes, the LT1 will get hotter and brighter but it will not use thermal step down.

Thanks, so will it get damaged running higher? I usually run it hours straight in up to 30degrees C static environment, Sounds like I best leave it stock.

Also I really wish they would put a 4 led volt meter on top of this, sorry but playing morse code with blinking lights is just unacceptable imo.

Temperature damage is unlikely. The LH351D are tested to 1000hrs at 3A at 85C. At 7*7135, each LH351D is getting less than 800mA at most.

The top might be so hot that it hurts to touch it, but it shouldn’t decrease the lifespan by much.

Even if something does break, the parts are pretty cheap to replace if you can do some soldering.

Hi
Does the Fenix CL30R have a built in volt meter ?

It has 4 led lights that gauge the SoC, not an actual volt meter with numbers. But so easy to use for the average joe.

Does anyone know what the waterproof rating is on this? Can it handle rain?

It handles rain no problem. I have used them in the rain many times.
