Well, it's a pity said regulations make life difficult for people who
actualyl want a lasting prodcut with soldered joints that don't fall
apart or grow tin wiskers.

My friends are moslty like me. They repair old electronics, and if they
can't do that they extract every useful bit from the device.
White LED lamps seem to have about the same phosphor
lifetime as
Right...
regular fluorescent lamps. I have some LED
nightlights in my halls
and I've observed that the output is slowly declining as they age.
I see, so the claim that I've seen made several times that 'LEDs don't
burn out' is downright false (not that I ever thought it was true, after
all, I've replaced plenty of dead LEDs over the years...)
Around here, a lot of the big box stores are offering
a credit
(usually $5) toward exchanging a string of incandescent Christmas
tree lights for the LED variety. Horrible, flickering harsh things.
I haev used LEDs in Newtonsday decorations, but running them off a DC
supply (so they don;'t flicker). The reson was that LEDs are easy to
drive from logic circuitry, so I'v ehad Newtonsday decorations controller
by a PDP11, PERQ, HP41, HP71 and HP48 over the years.
