I'm hoping that you just forgot to flip one of the two light switches for
the space, and that there are more lights on the other switch.
if the lighting situation is suddenly fucked i think the obvious solution
is to go on a lightbulb testing spree and restore lighting to sudo/CCL
with that method, while we explore other options.
two-bulb flourescent fixtures like ours can fail to light for two reasons:
one (or sometimes both) bulbs are bad (but OFTEN ONLY ONE is bad)
or the ballast is bad.
most people don't have the patience to figure out which bulb is bad, so
they replace one or the other or lose track of what they're doing and...
in the basement of the Omni there are many light fixtures with one bad and
one good bulb. Some fixtures have a bad ballast and two good bulbs in
them.
We should find a known good fixture (downstairs) and systematically test
each bulb we have (in that fixture alongside a known good bulb) and when
we're done, we can tape the bad bulbs into a giant log and dispose of them
properly, and install all the good ones in sudoroom/CCL right away.

CCL still has two functioning bulbs. sudo now has 0.
But we do have a neon "NAILS" sign.
That has to count for something.
Due to the complete lack of overhead lighting, I'd tend towards something we can get
our hands on quickly. Fry's sells bulbs, but Fremont. There are a few Lowe's
about...

so i guess sudoroom (and CCL too probably) need some new lights, since the
flourescents are failing.
Home Despot sells 11-watt "warm white" bulbs for $9 each, which would be
a good idea if we had regular lamp sockets to screw bulbs into...

but china can always do better. I looked on Ali Express and sorted by customer
satisfaction, looking for LED lighting in "downlights" which suggests lamps
shining
downward?
these look good but the seller rating is only 97.4%:

they seem to be "16 to 21" watts for $6.95 including shipping. They
offer "warm" and "cold" flavors so we could just get a mix of the two
kinds, for something in
the middle when they're all on.
here is the search i was doing:
http://www.aliexpress.com/category/200002289/led-downlights.html?site=glo&a…
this one is also a good price, and the seller rating is higher (98.1%)

ultimately i have higher confidence in the quality of something we buy from Cree at
Home Despot, but I think we should give China a chance and buy a few of the "16
to 21 watt" ones and see how they compare.
For reference, Cree (a reputable company) and other LED bulbs sold at Home Despot
are called "60 watt replacement" bulbs while actually using 9 to 11 watts. The
light fixtures presently in Sudoroom and CCL each have two 75-watt flourescent
bulbs, for a total of 900 watts of light in the bocce ball room when they're all
working.
That suggests that 150 watts of LED lighting would be equivalent, which would cost
about $60 from the first aliexpress link i provided.
These lights just have wires coming out, so we would perhaps attach them onto the
metal structures that are presently holding flourescent lights for simplicity,
until we come up with something better.
