LED holiday lights [RE-wrenches]

[sunwise]

If you gotta get "into" Christmas, this is the way to do it.  I'd say
they are all in series, chop em in fifths for 24VDC'ers and littler
chunks for 12V, say seven to a string.  Someone I know who bought some
says there are only 35 in a Blue string.  Aren't those blues higher
voltage by quite a bit, 3.75?  There must be 35 LEDs in the whites too.
Seems like they might be overdriving the mixed color sets and
under-driving the blues??  Ya gotta buy more color but the blues will
last you a lifetime.

The Forever Bights are a series string of 70, pull one out and the whole
string
goes dead. I measured the blue ones draw at 5 watts, and the multi
colored at
2.5 watts. I am not sure how they can series them to work on 120 VAC,
but they
are rapidly flashed (too fast to notice unless the lamp is moved) so
maybe each
LED has some kind of processor in it that limits the current and does
the
flashing? I am not sure how they work, but they are WAY cool and use
next to no
power. There are not too many DC only applications these days except
automotive.
