This got me to thinking again about all the reasons for choosing one bulb
over another.  One school wants the most growth per watt-hour (the
"efficiency" school) and the other wants the most pleasing appearance (the
"beauty" school).   What if you had two sets of bulbs, one for growing and
one for looking?    Or are there bulbs that give an adequate compromise?
