I suppose sending the device in for service will not be so bad considering Halogen Bulbs generally last for quite a while.
The way a Halogen Bulb works is actually quite amazing. For those who do not know, a breif summary: To start you have a Tungsten Coil which is surrounded by a Quartz bulb (they use Quartz because it has a high melting point, around 2X that of Borosilicate) The bulb is charged with a Halogen gas (hence the name) usually iodine and when the Tungsten coil is electrified, Tungsten evaporates into the gas and is then redeposit, completing a cycle.
As some of you might know "Halogens" themselves are inherently toxic, bromine and iodine gas being the two most popular to use in light bulbs. Do not fret though, the amount of these gases in a bulb is minute and would only be released if the bulb explodes.
I do have to mention the theory of boiling off individual chemical compounds at precise temperatures will be more difficult than it might initially seem. Even if conducted in a contolled lab enviroment you are dealing with natural plant material such as Cannabis or even Rosemary, which present many variables, such as:
"Where are the Active ingredients located in the plant? In the resins? in Tricome? The answer in cannabis is both.
This leads to a key word "Penetration", even if you expose a material such as dried cannabis to a precise temperature the active ingredients first exposed to the heat will vaporize first and the longer you expose the cannabis to the heat, the further the heat will penetrate into the structure and start boiling off the remaining "Actives"
Herbalizer may be able to adjust temperature quickly but as long as we are using dried plant material and not a laboratory synthesized THC or CBN compound, we will never be able to make a precise use of different "Actives" at their boiling points.
I guess my point is that even though the quick temperature changing of this device is a nice feature, it really is more of a novelty in my opinion, I for one have never felt a strong urge to drop the temperature of a vaporizer from 400° F to 200° F instantaneously. Most people I know have a very small window in which they even adjust a vaporizer.
Even though I envision the Herbie as my next vaporizer purchase, but I assure you it wont be because of the advertising which leads a buyer to believe they have invented a new type of thermostat altogether which can not be further from the truth. Most commercially available PID controllers will have the same feature set as the Herbalizer touts. What is that old expression, reinvent the wheel?
