At least running via battery does not seem to produce heat issues…

I did a run time test with a battery starting at 4.03V… cool white LED… highest brightness… shut down after almost 10 hours, but no heat at all…

That’s odd. Light should shut down much sooner at around 3 hours with max output and CW. http://budgetlightforum.com/node/61110

P.S. Since output reduces over time with depleting cell voltage, it is possible that max temperature of cell/tail cap is reached before the cell is depleted.

You’re right… my mistake… I meant: cool white.. dimmed to roughly 1/2 to 2/3… not full brightness… sorry for the confusion… it was at least 1/2 … rather 2/3…

No problem. Thumbs Up It’s good to know with reduced output heat is not an issue. All I know is that with max output with WW on my sample, my tailcap was on the warm side, but not worth worrying.
I think I will do more testing if I have time.

Maybe I should have post this at the “stupid questions” thread but here it goes.
If I understand correctly, electricity leaves the cell (discharging) from + pole and enters the cell (charging) from – pole. I would expect + pole to get warmer while using the lantern and – pole to get warmer while charging the battery. So, why and how the – pole gets hot when using the lantern?

Electricity is produced by a chemical reaction in the cell, throughout the whole cell, and flows as a current through the whole circuit. So there is some heat produced by the internal reaction which will be evenly distributed, some heat produced by the current flowing through internal cell resistance, which is again throughout the cell and evenly distributed, and some by external factors, such as the heat produced by the LED and distributed unevenly throughout the whole light, and heat produced by resistance to current at any point where there is a bad connection, thin wiring, or any other reason for bottleneck.

Thinking the current leaves the cell at one point and heat should be generated there is like thinking of the cell as a barrel of coal, burning from the top down, it just doesn’t work that way. The cell is more like a barrel full of AAA cells, each one generating current and heat evenly.

Used the T1 for 2 – 3 hours every night since I got it about 2 weeks ago.

The diffused lighting gives a really nice glow, I wonder if the multiple LEDs make a difference from a single LED.

With regards to the heat, I have a potentially stupid question- is the magnet being heated by induction? I would test it myself but I don’t have pliers to remove the magnet!

The magnet is heated by conduction. The primary heat source is the leds. Heat from the leds is transferred via the battery tube to the magnet.

Just for something to do, I ran the lantern on usb power for a few hours with the magnetic tail cap removed and then got a reading of 134F for the inside of the metal battery compartment.

Got my second T1 today. The spring has no corrosion just like the first one I got

Has anyone tried modding their T1?

In many ways it’s good light for me….

  • like the format (though 21700 would be better)
  • like the price (a lot)
  • like CCT (a lot)
  • accept the UI (though that’s definitely not my favourite)

But I despise how it doesn’t incorporate high-cri LEDs.
For a lantern I require at least 90 and highly prefer at least 9080.

I wonder if LED swap would be feasible….

Although high CRI would be nice, I’m a bit of a tint and CRI snob, I run the lantern around 3500K and have to say the light emitted is pretty tolerable, perhaps it’s the mixing of the two different LED spectra.

Unfortunately the Zanflare T1 is discontinued. So not available anymore.

Yes the $22.99 one,

But this one is merely “Out of Stock”.

This lantern appears to be more popular than expected. Gearbest cannot keep up with demand.

I am keeping my fingers crossed to receive the two I ordered on June 20th

Did you order your’s with the Freeme group buy? I heard they were delayed, but didn’t hear they were discontinued

Oh yeah. I did get a “shipped out” message! For what that’s worth.

+5 on the ramping speed, a little slower would be much better.

Not a deal breaker but annoying.

I would have preferred Zanflare use top button for ramping and On/Off. And botton button for Red and color blending (both which are done less often).

Otherwise great value and worth having.

On the light side.

Mine arrived and I love it. Compact, smaller than I imagined it, nice feeling, ramping could be smoother but nothing too annoying, has a strong magnet that easily keeps its weight, has enough power to light a room comfortably, seems perfect to use a few to light a house in case of power shortage and even the included battery seems good with 72 mOhm internal resistance (an unprotected NCR18650B already married it but still). I will test it in camping use for two weeks next month and see… It burns? It melts? It breaks easily? Manages being plugged-in and working for hours with/without battery? We’ll see.
As it seems now, I will, probably, order at least a couple more.

I used mine to light up a large 9 person tent this past weekend. It worked very well.

A 9 person tent!?

I still gotta get the hang of the UI, but in the meantime I just keep it stuck on WW and leave it.

Yeah, would be really nice to be able to turn it off with a coupla taps, rather than having to lift it up, find the button, and press’n‘hold.

I lied, it’s an 8-person tent, but you know how they size them up – 8 people in it would be like sardines in a can. But it was comfortable for 3. 6’10” center height is nice, too.

Mine arrived today and works great. Just as advertised, it’s a nice lantern and love the touch to dim top feature. Wasn’t dark enough to test before my son took it to bed but all th functions worked.

That’s nearly 100 LEDs on there, must be rather inexpensive ones. Looks like they maybe add a red one just to give some red color?

Mine is stuck “on”
the switch turns on the red, red blink along with all the other leds butt will not turn it off.
same thing with or without the battery installed (usb cable)
the touch control seems to try to switch tint butt can’t overcome the total output

I’ve had 2 for a few months now. So far no problems. I love them.

I am really liking mine too. So far no problems at all.
