[SML] LED back-lighitng for window

[Bill Conner]

Just on the dimming issue, if it claims and is close to 1%, of lumens, then
it will look like around 10% to the eye; 10% of lumens - your fixture that
claims dimming to10% - will look like 30%. Google dimmed vs. perceived
light for more.

For houselights I'm always specifying dimming to 0.1% - which looks like
about 1% and doesn't pop on and off too badly - and electricians and
architects don't understand why 1% isn't good enough.  Well,use to specify
and defend those days are past.
