| Flashlight Heating Things Up |
Been wanting to do this one for a while, but put it off after a few videos didn't turn out that well. Then I realized that I could turn the sensitivity down to pick up very small details or changes. This is footage of a Maglite with an LED lamp shooting at a black office chair from a few inches away. Specifically, it was a 3D (battery cells or las pillas) Maglite that was still shining pretty bright when I made the video. Don't recall if the beam was focused or not, but I don't think it mattered much at such a close distance.
From what I understand about light sources, they don't usually produce electromagnetic radiation within a single spectrum (i.e. a light bulb may not just produce visible light). Not sure if the apparent temperature change was from visible light or some other wavelength. Glad I'm not a physicist. Still, a pretty interesting looking video.
Reminder: Temperatures are not accurate.
