I have not tried this, but it looks promising: https://www.youtube.com/watch?v=aGSFZ2eadaA&feature=youtu.be

That's interesting. Holding onto the lamp will be difficult during this. Also, be sure to never touch the glass surface of the bulb with bare skin because the grease from your skin that is left on the glass will have a tendency to smoke and burn.
I would still prefer a hot air pencil, turned down so that you don't blow away everything else with the force of the airflow. It's somewhat more controllable in terms of direction and temperature and on a dense board that is what is needed. The professionals will use a hot plate under the PCB as a means of raising the "regional" temperature and then the air pencil to elevate the "local" temperature at the device just enough to loosen.

The video suggests that this is for use in situations where a hot air iron isn't available. I'd stand a better chance of having the proper tool than a spare halogen bulb and lab supply.
Neat Idea, although I worry about heat stress to the components being installed using this method.

I will admit to fast forwarding through the video. ;D

Awful I must say, use the proper tool, cheap as anyway.
Any of the AOYUE PRODUCT range will be fine.
Aoyue 8208 SMD Rework Station is the cheapest and will be fine.
You can remove and put down many SMT devices/components with such a tool.
Many folk fear SMT coz theyre using some antiquated soldering iron highly unsuited to the job!
METCAL's are VERY expensive but wouldnt use anything else.
However at 1/20 of the price a Aoyue tool will do nicely!

I think it's freaking brilliant!

If I had nothing else to use and I had to "McGyver" a solution for some reason, then I would consider it. Not my first choice, as is implied by the video.
Consider the dead horse to be beaten at this point.

One of Wayne Green's tricks was to "borrow" the wife's toaster oven and set it on "low". Wayne didn't worry about ingesting lead through his lungs or his Tater Tot's.
Those of us of certain age are lucky we didn't kill ourselves reading "'73" as children and teens.

The oven trick is a commonly used means to revive, for example, a defunct video card. Lead free solder isn't known for keeping a joint over a multitude of large temperature excursions, and those tiny bga chips are a real pain when mixed with lead free. You can find used toaster ovens all over, even new ones are cheap enough to dedicate to the job.

Remind me not to come to your house for chicken strips and tater tots.

So you won't be interested in the french fries fried in a strainer made from lead soldered window screen?
