Den has been busy with real life this fall.

Three Tanna leaves to give him life, nine to give him movement. But what if he eats the whole bag?

This is a light i would consider buying based on pricepoint. I really like lantern style lights over flashlights, the “flood” over a “throw” is way more useful for me. I wasnt able to find a good one, so I made one, intentionally rustic. I wrote up the sumary of it for another site, I wont “cross post” but the lessons learned I had were:
I couldnt find a good LED, everything needed something to defract the beam. But I didnt want a beam, so I sent with a G4 5W 580-Lumen 102 SMD DC 12V, this works great. I little more light output would be nice, but this is good.
I would have prefered something to hold up top, like a lantern, not like this coffee cup handle.
Having a beam that goes 360 around would be better than this, which is a little over 180 deg.
Its a 12v bulb, I am using unprotected laptop pulls, so I use the volt meter to watch their power and dont let it drop below 9v, that leaves them with enough juice to not over discharge.
Many hours of light. Two modes, on and off.

I will be building something to replace this, but if this BLF build first, I would buy that, again, depending on the pricepoint.

This is an awesome project. I really hope it gets off the ground. I’m very interested. Might buy multiples depending on price.

This is interesting, I will buy if the price is good.

I would be in for at least two if the finished product is as good as I think it will be.

The price and quality will both be better than good.

Happy new year to DBSAR!

It would be great to know how his project is going to in 2017 Smile

I’d be interested for one, possibly more depending on pricing. I’m all for a good (maybe perfect?) lantern… but this IS the budget light forum, so budget is key. That’s not to say I expect this lantern to be sold for 8.78 on GB! lol.. no, that’s ridiculous. But I certainly don’t want to pay $60-$80 for it either.

I’ve been looking for decent lanterns for a week, this is the most promising one I have found. Definitely interested.

If it can eventually get rolling to a production model then will be no prob.

Nice to hear from the “father of the lantern” Smile
How possible is that the lamp will get into production this year?

I don’t know at the moment, as The Miller is busy working on the BLF Q8 and BLF Thrower lights at this time, ( he has more resources to reach out to manufacturers than i do.

For those desperate for a lantern, just make a wire cage that supports a soda cup, use the cup as a mold for t-shirt fabric saturated with epoxy resin(use a sleeve), then drop an inverted foil cone in the top.

So, I was wondering if this could be an add-on to the Q8, like a lantern adapter of sorts. It could be something the fits over the light to make it a lantern, sorry if this is not reasonable, I’m new here.

This has to many diffences to work that way. (driver modes, charging, how the LED is set up, color tint, CRI, etc.

I think only the battery tube could be the same. … and the same as on other SRK flashlights.

it could, as this is configured to use four 18650’s in parallel as the other lights.

Any updates? I’d love to see Thorfire build this along with the Q8.

not at the moment, i believe TheMiller is probably a bit busy working on the Q8, BLF Thrower, and other projects to to want to bother him yet on this one. I do hope someday soon we can get this rolling though. I am adding a USB charging function to the prototype (TP4056 based) to add versatility.

I’m in too, especially with an incorporated USB charging function, as IMO recharging on the road without the need to carry an extra charger seems to be key for such a device.

OOPS.this gave me a little “whoops did I miss something?” feeling.
I thought you picked it up with Barry.

The Q8 has 4 “shade points” at 90 degrees from the head (so when shining it and holding it perpendicular to a wall a shaded point is seen, caused by the point in the middle of the quad reflector.
How about a good diffuser?
Good quality,downwards facing reflective dome, with a metal frame (using the shade areas for there is less light there anyways) that has a handle so it can be hung and carried like those old fashioned storm lanterns.
And maybe a piece that screws into the Q8 between the tube and head that has the electronics for the charging (and powerbank) and connectors in it.
diffuser could be made so it clamp in between 2 cooling fins at the switch side and fixed with a nut in the tripod mounting hole.
So a camping addon set. because of powerbank also cool for normal users.
Could be a big demand for it.

As was discussed in the Q8 thread, adding a lantern attachment to the Q8 should be pretty simple, just a matter of getting the reflector angles right.

Adding a charging circuit on the other hand would be a much larger issue, it would require a new driver and most likely a redesign of the body itself, at least to some degree, at the very least for the USB port itself.

Although charging a Q8 should really be done with a USB type C connection to get any kind of worthwhile charge times, this would need the cells to be in 4S to work effectively though but it would allow for 10X faster charge rates.

You could possible add a charging circuit to the tail section of the Q8, with an extended tailcap, although charge times would be VERY long indeed. Talking ~10 hours for a full charge.

What? Put the cells in 4S to charge? That’s the worst possible way to charge Li-Ion cells! Where did you get the idea that the charger circuit “would need the cells to be in 4S to work effectively”?
