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

As discussed by DBSar and me, using the Q8 MCPCBs will help a lot with costs and modding simplicity.

It also makes testing much easier since we can easily buy the MCPCBs now. I have 3 on the way.

Edit: I am sorry for my attitude.
I had not thought about alternatives not costing much money at all.

number 845 on the interest list.

Please stop guessing what the costs will be of particular components, you are probably wrong and it will influence the design process in a wrong way, namely not the best lantern is designed but a lantern that according to some BLF members’ wild guesses is cheap.

In the Q8 design process we tried to avoid thinking for the manufacturer as much as possible, and the end result had features that early in the process we thought we would never achieve, and we still got it for the original price goal.

As for using the Q8 board design, having a dedicated board designed for the lantern makes a lot of sense and will probably have no influence whatsoever on the costs, making DTP led boards costs very little money nowadays.

Aah I had not thought about it that way.

Thank you for correcting me.
Maybe I was thinking that way too much for reducing costs.

I’m sorry for repeating that too.

Thank you Djozz for the better perspective.

Interested in two. Depending on price of course.

you are numbers 846 and 847 on the interest list

Interested in Group Buy.

UPDATES Cross section of the BLF V2 lantern added. Further field testing going great! photos coming soon. also will have more detailed specifications for the lantern to provide to Barry & Thorfire soon. All we may need is to find someone to draft up a CAD of the lantern in the cross-section drawing below if Barry needs a more detailed version for Thorfire to work on.

Sbslider can you PM or email me a text-file of the list so i can update the OP? Thanks :slight_smile:

SilentObserver is 848 on the interest list

Looks like progress! Thanks for the update. :+1:

What if the “shade” was a cylinder rather than a cup?

The top surface of the “aluminum threaded shelf/base” could be left un-anodized to help reflect light.

This would save a bit of polycarbonate and eliminate the paint, but I’m not sure how it would affect the lantern’s strength or otherwise change its construction. Just a thought.

I like the idea of amber switch LEDs rather than green ones like the Q8.

Looking forward to the new photos. Hope you had a great trip!

Nice cross section DBSAR, is there also a notch and pin on the lens and base so they can’t twist and damage the wires?

Interested in two please.

Put me on the list for one please.

Nice to see some progress! But what happend with the tint ramping option we discussed earlier? As far as I understood it, we would need at least 6 LEDs (and a new LED board) to make that work.
Also I thought that our priority is to create the “ultimate Latern”, not the cheapest.
And please add me for a second one.

I would be interested in this, please add me to the list.

Definitely interested. Those Samsung LEDs look really nice.

Is it intended that the lantern is water resistant? The schematic shows an o-ring at the base of the diffuser, but nothing at the top or around the center screw

The cup shape makes it much stronger than just a cylinder type shade. i did test that shint base reflector idea originally, and the flat-white surface increases light reflection and reduces the hard-light glare and bad light distribution flaws of most factory lanterns i tested & used. (shiny or chromed reflectors cause to much glare & artifacts.

The cross section can;t really show it, but the shade would definitely need either one or two index locking notches at the head area to lock it from turning. (Same goes for the base)
