Just got mine today. I am curious what type of add-on accessory people are buying to use as a handle? Just a big lanyard, or is there some other accessory that can be added on?

I made my own lanyards for the LT1 from 550 Paracord. Big Smile

Has the option of a high efficiency driver been considered? I’d be cool to have that as an upgrade option when buying an LT1. Maybe Sofirn can commission Loneoceans like Fireflies did to build them an efficient driver? That along with SunLike LEDs offered stock would truly make this the endgame lantern for me.

Does the LT1 when fully charged, the on/off button/glow switch turn green. Mine is orange and I have put in on charge for like 5+ hrs still not turned green. Charging with battery charger that was shipped by default

The button is orange by default, and will turn red when you plug it in and start charging. It will turn green when it hits termination. It does take quite a while to charge all of the way, depending on which cells you have there’s a lot of capacity and I don’t think the charge current is very high.

Anyone know if Sofirn is still doing codes for those of us that weren’t able to place orders for more than one before the world shut down?

BLF GT, GT70 and LT1; Olight S20R, SR Mini II, SR52-UT, i3E EOS i1R EOS, i1R 2 EOS; Jaxman U1 UV

With completely flat cells, it can take as long as 10 hours to fully charge. The charge current is only 1.5A.

Make sure the red LED illuminates under the button cover to indicate that it is indeed charging when you plug it in. The older rev driver board will not charge with a USB-C to C cable (must use USB-A to C).

I got a code about a week ago for an orange one in one of Sofirn’s threads. It wasn’t as good as the initial deal, but it was better than retail.

The cost is not worth it. It might be as much as $15+ for components alone for not all that much improvement. You’re already getting 4+ hours on high with 7 7135s.

Yes, you’d gain maybe 15- 20% efficiency at the start at most but that efficiency gain decreases as the batteries discharge. It won’t even make a difference heat wise since the LEDs are far away from the driver.

On top of that, you’d have to pay people to design the driver and much more.
