Another Enlightening Question From Readers

and it only cost $11!
The second most prevalent question has been about my choice, methodology, and design for
lighting. The short answer is, "lots of it." There was no real design, per se, to the lighting
other than to hopefully provide more lighting than necessary and then add additional lighting above
the locations where my workbench and drill press will be located. I have always had a hard time
seeing clearly at the drill press.
In the main shop area there are eleven 4-foot long fluorescent fixtures, each with two 32-watt
bulbs generating (claimed) 2950 lumens each. Above the entry door, I installed a circular
fluorescent fixture with two bulbs putting out a total of 2975 lumens. The fixture was a clearance
item that I got for $30, including bulbs. I had a three-light spotlight fixture purchased for a
former house and that was never used. I "repurposed" that fixture and installed it above the future
location of my drill press. The individual spotlights can be turned and aimed as needed. There is
a wall sconce light mounted just inside the double door, and several windows produce a nice bit of
indirect natural light during the day.

stairs and down on the
eventual location of my drill press.
In the big box store there were several options for fluorescent fixtures. My favorite was a
white fixture with a large reflector. Interestingly, they have two versions of the same light. One
includes a pull chain switch, a plug-in power cord, and the "S" hooks and chains you need to hang
the fixture. The other is meant for direct wiring and has no pull chain switch, no power cord, and
no mounting hardware. The direct wire version sells for $10 more. No one could fathom the reason
for this apparent pricing anomaly.

into a switched outlet assures future flexibility
and saved a few bucks!
Internally, both lights are identical. Both have the same electronic ballast, which is important
if your shop gets cold. These ballasts will start up the fluorescent lights when the temperature is
well below freezing. Conventional ballasts often will not work in these conditions.
Eleven lights at a savings of $10 each helped me make the decision to go with the plug-in
version. I wired up electrical outlets in the ceiling on two circuits (zones). The lights are
permanently mounted, no chains and "S" hooks. Both lighting zones are controlled by wall switches
mounted just inside the door. With just two switches I can turn on all the overhead lights in the
shop, but I still have the flexibility of turning off specific lights when not needed by virtue of
the mostly unused pull chain switches.
At some point in the future, I may do a little research into footcandles and lumens and maybe
even borrow or buy a light meter so I can see if my "guesstimates" were correct. For now, though,
the shop and my lighting "design" seem very bright.
