*BLF LT1 Lantern Project) (updated Nov,17,2020)

Those could be a possibility.

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?

Not sure if anyone has them in stock stateside but from Sofirns website has the best price.

Just bought one from amazon canada shipped by amazon . If available in amazon us. PM sofirn for a discount code . Ended up same price as sofirn but with fast delivery and no hassle returns .

Finally remembered to check this after dark with the lights off - that is, when the “glow” was visible. The glow disappears when the battery tube is unscrewed.

I keep meaning to open it up, but I’m never near hex wrenches (to open the top) when the inspiration strikes. Then I get distracted… I at least checked the topside of the driver just now, and nothing looks out of place.

As for the adjustments on the solder bridges: Are 6 and 7 on a separate channel from moonlight, or would bridging them increase the brightness of the lowest level? I really like the low, warm output as a bedside lamp. I wouldn’t mind a higher high.

Brightness isn’t completely flat while changing tint. It tries to adjust output to keep the brightness close to the same, but it’s not perfect. Brightness is expected to be slightly higher or slightly lower in the middle than it is at either end of the tint spectrum.

Going from 5 to 7 chips causes all levels to be 7/5ths as bright as before… including moon.

But at only like 1 lm to 1.4 lm, it’s not a big difference at the low end.

Why is this so expensive? I checked amazon.ca and it’s a hundred bucks!

pm sofirn for a discount code . with batteries it’s $81 .

Carry case for LT1 is availble now! Buy LT1 and case together, save $2.5

Thanks Sofirn,
$55 w/case…… thats a good deal! …… I already have one but plan on two more when colors are available(OD green & Desert tan)

Im half tempted to order another lantern to see if the new shipping process will beat my light stuck in Nanning.

Not sure if anyone noticed the SOS Mode?

Driver Rev. 5.0 is installed.

After Beacon Mode there is the SOS Mode.

Where normaly the Temp Check can be found in Anduril Flashlights.

Thanks for this great project.

Success! After 6 months and a replacement shipment later, I finally have mine!

It’s incredibly well built, definitely worth the wait.

The later versions of FW have SOS mode, its a good add IMO. Good to know the newer lights have the newer FW also.

LT1 has no temp sensor hence no temp check.

If its ATtiny85 or 1634 based it has a temp sensor. It was probably just removed because it will never overheat even with all 7135s enabled.

Thank you, Toykeeper. If I bridge the 6th and the 7th pads and set the stepped mode to 7 steps, will the first 5 steps be equally bright as the 5-stepped modes (like a default setting) before bridging?

I have got a BLF LT1 Rev 5.0 and soldered the pad 6 and 7 to increase the current (previously I drew a line with a pencil, but didn’t notice any difference in brightness). Still don’t feel that it’s brighter. Did I miss anything?

Pads 4 & 5 are not connected. At least on earlier versions, the lower number pads need to be connected for 6 & 7 to have an affect. Using a pencil should work, try that on 4 and 5.
