The best tent lantern!!

[branw33]

I wired an individual LED from a strip to a usb cable, cast it in acrylic for protection and boom, ultralight LED tent lantern! It will run for about 30 hours with a small 10,000 MaH power bank.
Would be happy to make them for anyone interested.

This is awesome! Good idea!

That is an incredibly cool setup. For S’s & G’s you could solder in a marine-grade potentiometer (adjustable resistor) for about 2 bucks and be able to dim the light and extend battery life…I might need to do some tinkering this weekend and make one. Thanks for sharing

Do potentiometers actually extend battery life? I was under the impression they just increased resistance so the energy that would have become light now becomes waste heat.

Touché. It would allow you to dim/brighten the light, however, me thinks you are correct in that it wouldn’t reduce the power draw from the battery; that would require a lower rated LED. I have a few on order to mess around with, I’ll run a multimeter on it at different resistance settings and see if the amp draw changes, but I think you nailed it.

nice how much would something like this cost. i have a bunch of batteries already

That's pretty cool. Do you know what the lumen rating is on the element?

Like $5-10 depending on if you have a usb cable. That's really the most expensive part.

Neat set up I can see this as not only a tent light but it would be good for a late evening field dress and meat prep for a pack out along with a head lamp should light up you’re area pretty good, should even be ok in wet weather with a bit of plastic wrap and some elec. tape around the connections. Mongo like.
