 I think if the charging port really bugs you just hammer it full of silicon caulk , push in the rubber plug and call it good . 


 


 

That’s what I plan to do

I know it is not economical or practical for this lantern, but for a possible future project I think a really nice idea would be a retro look lantern based on an old paraffin/kerosene hanging lantern design, perhaps a small brass version.

The charging port could then be very nicely sealed behind an O-ring sealed metal screw cap with a chain retainer, that looks like the old fuel caps.
Brightness/CCT control via a rotary switch could resemble the wick adjustment.

Beam me up!

Cool idea. Maybe for a future model as a LT1 “Classic” model once we get this first lantern into production.

I think for a classic look something like a Davy Lamp ( https://giftwarewales.co.uk/collections/vintage-welsh-miners-lamps ) would look better than the old Parafin styles?

I have a brass version of something very similar, it uses candles, but in a very different way. The candle is inserted into a metal sprung tube which feeds it upwards as it melts, keeping the flame at the same level.

Actually I was thinking of a less ornamental version of something like this:-

craig-IL sounds like Craig from Illumination Supply. He was on the forum for a couple of years but never did anything remotely questionable at least back then.

Hey guys. I am a big fan of the clip-on “glare guard” attachment of the Streamlight Super Siege.

I find it a brilliant idea: simple, yet useful, especially when using the lantern as a work light. And it is supposed to be quite inexpensive to manufacture, it is just a piece of plastic, after all.
I think it would be awesome if something similar would be available for the BLF LT1, either as an optional or standard accessory. What do you think?

It would be interesting to know how the diffuser wil influence the light in matters of cri and color temp. The one I use makes my lights look cooler. I know it won’t be possible for this one but, somebody spoke of remote phosphor domes. Wich I believe would be perfect for a lantern. I have looked into them but they seem not available anymore. I know yuyileds (?) uses them cause I broke one of their bulbs. The bulbs are really nice but could be a litter warmer for my taste for some applications.

A diffuser will blend the beam, even if the tint is all over the place from 4000k in the spot all the way to 6500k+ on the edges, which means tint shift goes away. However, that means the beam is blended, meaning that 4000k spot/6500k edge will now become a 5300k tint, which makes the light seems much cooler than it actually is.

Samsung’s LH351D 90CRI 3000l-4000k-5000k have been tested to have very little tint shift, so that should not be a problem at all.

The LEDs themselves have little tint shift in the beam for the 90CRI versions, so normal silicone diffuser should work without any problems, if it’s made consistently of course.

Thanks for asking that question though!

Does anybody know a source for good high quality diffusers?

Yeah, that’s way beyond what we can do in this project. That’s the sort of thing LED manufacturers experiment with for household light bulbs, not something we can reliably get produced for a lantern.

It’s not even used much by LED manufacturers though. Philips did it for a while with their L-Prize bulb, but it didn’t stick around long. It was expensive, and people didn’t like how it looked.

The main counter-example I’m aware of is a lightsaber blade called a photon blade. It shines a royal blue emitter into a phosphor-coated tube to produce a bright green light. But it’s nowhere near white, and the blade alone (without emitters or a host or driver) costs more than the lantern’s estimated price.

Those are some funky looking light bulbs. I can’t find any of those remote phosphor domes, I did find a store where they where out of stock and they not really budget friendly.

Very simple, very interesting.

But I’d check if white works OK, so it reflects some light back to the head for increased efficiency. Could be a worse blocker like that, so maybe it’s not a good idea.
