:I'm thinking it's a reference to the Cyalume lightsticks which need to be bent, which shatters a small glass vial inside and releases a hydrogen peroxide solution into a second solution of an oxalate ester and electron-rich dye contained within the outer plastic shell. The resulting chemiluminescent reaction creates visible light.

:I assumed main sequence refers to stellar evolution in astronomy. {{w|Main sequence}} These stars have a relatively long life, matching the description. The SPF 15 coating and full spectrum would also make sense. However I am not sure that description as a chemical flashlight would follow appropriate. The primary energy generation would be nuclear (fusion). It has been long enough since I took astronomy I don't remember all the details of how the energy is converted into light, and whether that would ultimately be considered a chemical, thermal, or nuclear process (or combination thereof).

"One pixel display" - I was surprised by the suggestion that this could be a static image, like a slide; I had imagined, and would like to see (perhaps more explicitly) the alternative, that the whole screen simply lights up in a single color (within the __-bit colorspace). --[[Special:Contributions/108.162.245.177|108.162.245.177]] 17:03, 21 September 2023 (UTC) | "One pixel display" - I was surprised by the suggestion that this could be a static image, like a slide; I had imagined, and would like to see (perhaps more explicitly) the alternative, that the whole screen simply lights up in a single color (within the __-bit colorspace). --[[Special:Contributions/108.162.245.177|108.162.245.177]] 17:03, 21 September 2023 (UTC) | ||
− | + | I agree with the latter - I would consider the pixel as the minimum picture element, no subdetails. [[User:Vdm|Vdm]] ([[User talk:Vdm|talk]]) 20:30, 21 September 2023 (UTC) | |
:A single pixel with a lot of display states need not be static. Show a bunch in sequence like a film based movie projector. Pixel is the minimum addressable picture element. Think about ASCII art (e.g., printing Mona Lisa on a daisywheel printer), or graphics on the IBM PC monochrome display, Commodore PET, etc. There are also those pieces of art where each pixel is a small photograph (I don't know if there is a name for that). Not typical pixels, bit of a gray area. [[Special:Contributions/172.71.158.15|172.71.158.15]] 21:10, 21 September 2023 (UTC) | :A single pixel with a lot of display states need not be static.
