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

So, here is what we should do for options:

1. Lantern only.
2. Lantern + 4x18650.
3. Lantern + 4x18650 + carrying case + (if possible) aluminium diffusion sheet.

What about a charging cable? Personally I think a cable is more important than the batteries. I don’t want to settle for low tier Sofirn batteries. I don’t really need the cable, but I think most people might need one, especially if buying the case.

[BlueSwordM]

The cable would be included in all versions obviously…

A flashlight that is supposed to use 4x cells should have a USB cable included.

I can understand with an 1x18650 flashlight and a micro-USB cable, since there are way too many m-USB cable on this planet already.

But, until it becomes as widespread as micro-USB, every USB-C light should include a cable, batteries or not.

If this lantern is offered with an adjustable/removable deflector I would be in for several lantern/kit packages. The common discussion within our group for many years worth of outings has been the lantern/light level and whether or not it is shining in anyone’s eyes or not. It would be a shame to have to rig a deflector as an afterthought for such a refined piece of kit.

Thanks for the detailed explanations! Tint adjustment sounds like it’ll be intuitive to use.

@ToyKeeper

I’m thinking auto-tint would probably be enabled if you ramp to the end and keep pushing after it stops. Then to turn it off, ramp back into the regular CCT zone to go back to a steady tint.

This seems like a great way to toggle auto-tint.

@ToyKeeper

Sunset mode isn’t configurable yet, but I’m hoping to fix that at some point. It really should be sharing timer code with candle mode.

Nice! :+1:

BTW, what does lightning mode look like with auto-tint enabled? Warm, dim lightning bolts and cool, bright ones?

@ToyKeeper

Holy crap, I have a lantern. And it works!

I’m so glad you got a pre production copy you can play with and fine tune your firmware. This tint ramping sounds very exiting, but I’m sure will take some polishing to work well. I can’t think of anyone better to pull it off.
I really like the auto tint idea.
I like to have a flashlight on low moonlight as a nightlight and quickly locateable in the event of an emergency. Any idea how efficient this light will be when left on in lowest mode? With 4 x 18650 and low current, I’m guessing it should last 3+ months.

Dont worry! I am working on a host of accessories already for the lanterns accessory kit. :+1:

Having been using the tint ramping firmware for a few months now I do like the idea of the auto tint however I am not sure I like the idea of “pushing” past to edge to set auto tint. Often I’ll find myself in a lower mode that doesn’t use a particular channel in low but it turns on later as I increase brightness. So I’ll often ramp for a while to one side to know I hit the edge.

So given this I’ll offer an idea. How about setting auto tint the same way we set step ramp? A predefined number of clicks or hold combo would set us in auto tint and disable with the same combo.

I don’t know yet, but yes, that’s how it should look.

It looks like about 5.5 mA (3.5 months) on moon, but that’s with all 7x7135 enabled. It should be a bit lower with fewer 7135 chips. And if I understand correctly, it should ship with 4 or 5 chips enabled per channel.

Or there’s standby mode with the button on, which is about 0.1 mA (~16 years) at the brightest level.

I am not sure I like the idea of “pushing” past to edge to set auto tint. … I’ll often ramp for a while to one side to know I hit the edge.

That’s why I’m planning to add a blink when it hits the end. I’d want to add it anyway, because it’s hard to tell where the edge is… but it can also help make the auto-tint thing more intuitive. Hit the edge, keep pushing for a full second, and then it’ll go to auto. Something like that, anyway.

[Edindevon]

Can I please be added to the interested list. Thanks.

[Thrust84]

Please add me to the interest list. Thank you

[BlueSwordM]

@Mr.Scott and others, don’t forget about the general public.
They quite literally need this, so I’m not going to remove batteries for this.

The accessories will probably be sold separately and for cheaper if you don’t want to get 18650s.

[cvaty]

please add me to the interested list

[mikewilzn]

Definitely interested here.

[jigsaw]

I’d buy the battery package if they were good batteries. Don’t need any 1500mah trustfire clones.

[mountainair26]

Interested in one or two pending price

[tocirahl]

All right fine; add me to the interest list for one lantern. Thanks for the hard work, everyone! Looking great.

[jeep157]

First time posting, actually created this account to say I want one. Is there anywhere else I would need to say that? Or is this sufficient?

[bquinlan]

Please add me to the interest list. I’m late to the party but it looks like a great design.
