Folks, lets also recall that the laws of physics still apply here. Some materials just heat up and radiate heat/energy more quickly. Such as the materials used in quick-heating on demand vapes.
But the appeal here is the halogen and its incorporation with balls. That is giving the great flavor and high quality extraction.
But gotta live with the tradeoffs. Not only of the bulb itself but also the fact that the balls take some time to absorb that heat as well.
If speed is what you prefer over flavor and top tier extraction, look elsewhere. There are lovely vapes above and below this price point that can satisfy those prefs.
Batteries getting hot is part of that physics equation too. Multiple back-to-back sessions can make this pretty warm, especially the metal where the mouthpiece meets the body. But not uncomfortably so, or to the extent that I'd trade that beautiful wood for a heat sink design seen on the Mighty. And common sense suggests waiting on a device to cool down before mucking with hot batteries or battery chambers.
Taking the popular Murata (formerly Sony) VTC6 16500 as an example, their fact sheet shows that they are rated to discharge safely as long as battery surface temp is below 80C (176F).
