Completely agree. I'd most liken it to convection because you set the temp & the halogen bulb heats to that temp & when you turn the heat off it rapidly cools, like a 510 box mod. Agree?
Yes! It's interesting because the bulb turns on and off to maintain the ability to quickly reach the set temperature. The fan is key for that. Without the fan running there is no radiant heat.
The temperature is measured by a tiny probe below the bowl, which u can see. The probe is covered by two stainless screens (which trap hot air below the bowl). The bowl sits on top of those screens and comes on and off via a magnet. The fan has a slow and fast setting. To maintain temperature at the probe, the bulb comes on as well as the slow fan setting, both on for less than a second at a time. This happens several times a minute.
Between the time the slow fan and bulb come on, you can touch the screens, its that cool. But when the slow fan comes on, I would not put my finger on the screens. However, as little as a quarter inch above those screens and u just feel hot air, but it wont burn you as the air rapidly cools as it comes into the room. The slow fan setting only pushes enough air to keep temp probe up to temp, not enough to really heat the bowl or herb.
What I mean is if you left the bowl on the device with herb in it, you probably would get some radiant heating, with fan and bulb coming on to maintain the ability to heat really quickly, but it's not much. I think after an hour (if the device didnt shut off) you would still have green bud.
Now if you turn on the fan to inhale (the fast setting), you're pushing some serious hot air through that small bowl. Without the bowl there, keep your fingers away!
You can also just draw and the bulb will ramp up the temp.
In sum, its convection heating, not radient heating. And sounds very similar to the mod you speak of....
The benefit I have found, is the herb literally never tastes bad or like conduction popcorn. The flavor
goes away or diminishes as you vape, and it gets dry, but the flavor never
changes--if that makes sense--because it still tastes the same, i.e., good, as it turns brown, just with less of the initial flavor...
To tie this into the original posters question, yes, this device will produce very consistent effects at the set temperatures because all of the herb within the bowl is vaped at the same temperature. Whereas other devices with the same weed, especially conduction devices, I don't think come close to the same consistency. The outside of the bud will be vaped at higher temps depending on pack and setting. And other convection devices, e.g., Evo, have much more radiant heat. So if you leave the herb in the device its gunna bake, changing the experience.
