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!
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.
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.
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 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.
