Repeat spectrographic analysis of the red LEDs in the LED Battery-Operated Christmas Lights; spectrometer's input greatly overloaded (even more so than the last two analyses) in an attempt to find a blue, blue-green, or green pump wavelength because an expert in LEDs who's work I implicitely trust speculates that this may in fact be a phosphor red LED! Spectrometer's response narrowed to a band between 410nm and 470nm to pinpoint native emission peak wavelength, which is 442.700nm; this confirms without a doubt that these are those wily and elusive phosphor red LEDs!

Spectrometer's response narrowed to a band between 410nm and 460nm to pinpoint native emission peak wavelength, which is 440.220nm.
Note the spike at ~440nm; this pretty much discounts spectrometer noise.
