The Coleman Gas Lantern that runs on LiIon..

This module would work on the larger Primus or Optimus lanterns as long there was enough room under the top vent to hide the battery packs. ( though i dont have any of those makes or models, the closest one i have is a Petromax style.

So far i don’t have a host yet, but i’ve been enjoying the starry light and it has good modes, so i am reasonably confident i can program a 105C (won a programmer in a giveaway, have not tried it yet), i figured 4AA in series, on a swappable plug like those cheap bike lights, at 200mA it would last 10 hours (about 100 lumens), then swap for the next battery pack (4AA).
Your host seems excellent because most cheap hosts are plastic and provide no heatsinking at all, if i make a light like this i can hopefully come across an old lantern for a few bucks somewhere

Where is the diffuser your using from?

These lanterns are meant to withstand a lot of heat and with all the frame made from steel, (many older models like the 236 - 237 used solid cast brass burners and gas frames, which make great heatsinks.
The diffuser is one i salvaged from an old garden LED light, with a piece of white hair-net over it to simulate a lantern mantle.

I know, thats why i am sure they would handle LED heat without difficulty unlike dollar store lanterns.
If there is a cheap diffuser available that would be great for this mod.

So far of all the diffusers i tried (even factory ones) the one that came with my Sunwayman F40A is the best i tried with the least loss of LED output.

I bet you could sell thousands (or millions) of these if you put it into production…Shark Tank!!!

From Wikipedia:
“more than 50 million of the (Coleman) lanterns have been sold throughout the world”

How hot does the lamp get when running on fuel? Wouldn’t you be in the dark for a while waiting for it to cool down, if you ran fuel first and had to switch?

Wow, what a creative and useful idea, I love it! I remember my lantern getting hot enough to give very serious burns. In the dark while it cools down? You do know that this is a *flashlight* forum right?

peace

Well, I was thinking about the area lighting. Of course a flashlight counts as light, but isn’t really the same as a lantern. Then again, if he had Dale’s 14,000 lumen monster XHP70 Triple, he could hang it in a tree somewhere near camp and have daylight!

Nice build! Love the low tech high tech combination :heart_eyes:

That bulb/net thing looks amazing. Could be fun to se it beside the original low tech gas “bulb”

What a work of art, love the mantle. I really thought the first picture of the lit mantle was the “before” shot.

Love it, think you can sell a bunch and I’m in for one!
Later,

Wow. Congrats on this creation. As usual, top notch.

from the globe up it gets really hot. There would be a 15 minute or more wait for it to cool down.

It uses “flashlight” parts to build it (and its in the “Lantern” section of the forum :bigsmile:

That’s extremely cool, as it can be used indoors. Now you just need a way to generate that signature hiss of the pressurized gas lanterns.

maybe a small AM radio hidden behind it with the tuner set between channels so the static plays at just the right volume. :bigsmile:

A custom sound module would be cool, you could select from different noises. I believe car companies have gotten a bit creative on sound modules for hybrid cars so people can hear them in parking lots, especially the blind.

Really neat build. Who would do such a thing? I wish I thought of it! I love how unique, intelligent and straight forward this design is. It must have been a real struggle to keep it so simple and clean even with that remote. (If it wasn’t a struggle then lie, embellish a bit to make me feel better about myself) Nice, keep it up.

its just a simple design with common parts we use for flashlights. :slight_smile:
