They do. I've read it. The reason for it is that they sell
a current balancing chip to minimize visible brightness
differences by actively balancing current usage. Having built
a 10 LED array (for a tent lamp while camping for two weeks) by
wiring 10 white LEDs (from BG Micro) in parallel to a 3.6V
Craftsman VersaPak battery, each LED ranges from blue-white to
purple-white to cyan-white. The app note describes having several
loops of LEDs in series. Given a better design that I had, that
makes more sense. OTOH, I put mine together with stuff lying
around the house and garnered at thrift stores! Plenty of light
in a 12' diameter tent for hours on end.
