As long as we’re wishlisting, I’d totally buy this if it existed:
Really though, it’s the blue/purple/red parts I like the most, not the orange/yellow/green bits.
However, by itself, a bright neon traffic-safety yellow reflective glow-in-the-dark coating could be fun. Maybe give it an amber LED or a 2200K ultra-warm to emulate sunlight at sunrise/sunset. Add a pocket chain and wear it with a yellow zoot suit.
For GITD it would be best to have a white coating first for best results I guess. Safety yellow in combination with GITD (maybe even the blue stuff) should look interesting.
Doing some quick research it seems that GITD may not be up to standard, it’s perfectly possible, but reading up about people using it, it seems like it shows up with an uneven blotchy finish, not a nice uniform glow (it can also only be used with light colours for any chance of seeing the glow)
Possible, but it’s not the powder itsself that glows, it’s a pigment you add to clear/white coat.
So you would get a speckle effect. Obviously the more powder you use the less noticeable it is. But if I use too much the original powder won’t cure (the glow powder doesn’t ‘melt’ but bonds and glues with the melted powder coat, then cures)
Just FYI: Powder coating is an effective thermal insulator when applied to metal (even at the typical 60-80 micron thickness). So not a desirable material to be used to coat an aluminum LED flashlight… which generates heat and requires a thermal path to the ambient air to cool the emitter. Even worse is the possibility of overheating the battery due to the trapped thermal load.
IMO - although the colors can be vivid and pleasing, Id avoid this one.
