Re: Curious
@Allan George Dyer
My mistake, already corrected (before I saw your comment). For those wondering what Allan is talking about, I accidentally wrote that blue LEDs paved the way for yellow LEDs, which is clearly ridiculous.
What they did was pave the way for white LEDs, and this was done, more-or-less, through a yellow coating, which works to not only produce white but, as the eye is more sensitive to yellow than blue, increase the apparent brightness.
