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.

HA, HA, HA!!! You tear me up!

Hmm, and here I was being serious for once. shrug


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.

Yeah, not a problem for you!

Two runs of Romex are too much for you, Bill? sigh


Actually, I have 2 other fluorescent
fixtures powered by my main-panel, rather than my sub-panel, which I
regard as my back-up system. I would do what you suggested except it
would confuse my wife... I'm not sure I could even field the question:
why are there two more light switches on the wall?

A simple "Try each one and see what it does." is too much to ask, eh?
Then the "I switch one on for normal use and both for 'OMIGOD, I'm
gonna go blind!' lighting. Here are your sunglasses." Do that only
after you've built the sunglass case on the wall into the shop.



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

That's good info to know. No switches, in general, huh?

Right. Just as the cheaper shop lights usually come with plugged
cords.


Happy Friday,

Enjoy your feckless and fun-filled Friday, sir.
