You just got a free lighting design, enjoy it.

When you first wrote that I thought 1 luminaire was a 4' bulb.
Now I think you mean(t) 1 luminaire is a fixture with two 4' (32w)
bulbs. Starting to feel like I'm making more out of this than there is,
but I don't want to be disappointed when I flip that switch.

If you go with Lew's recommendation, I hope you put alternate fixtures
on a separate switch. That way you can have nice lighting or GAWD
THAT'S BRIGHT! at the flip of an extra switch.

If you have 5 rows, put rows 2 and 4 on the second switch.

I already (this summer) installed a single wall switch for all of the
fixtures and run wire to and around the attic.

It wouldn't be hard to add another switch and reroute the wiring,
would it? One Saturday morning would do it.


It would be nice if
each fixture had a pull-chain switch so I could be energy efficient in
my general use of lighting.

How often would you like to do that? Wouldn't a switch be nicer?
One feed, two strings of lights, not a problem.

Another problem you might find is that many good manufacturers don't
put pull-chains in their fixtures.


I learned alot about fluorescent bulbs, and
how important reflection is this week (both in the walls and ceiling,
and in the fixtures).

That's why I went with pure white paint, and did the ceiling and floor
white, too. It makes a significant difference.

Now, the floor is covered with both sawdust and too much STUFF to even
be seen. sigh
