Until we can find our own, we've been using a church for our rehearsal/performance space. On top of the usual problems, our biggest challenge is lighting. Presently, we have lighting from directly above that we can turn on or off ... nothing inbetween. These are not stage lights, but simple everyday lights. We don't want to turn on the house lights during the show to get more light on the faces of the actors, for obvious reasons, and would like to know how other CT's handle this problem. Any suggestions would help. Thanks.

You could get some PAR fixtures and power suplies like DJ's would use for party's. The size of the stage would decide what fixture and what wattage. I would't use more than a 500 watt bulb. You culd put up a truss to hand them from, or mount them on a base for footlights. They would be lightweight and easy to transport.

As Tim suggested a lighting tree parcan rig is cheap enough with some form of dimmer control & is very effective.
You will possibly find a lot of unused lighting equipment in your
community, especialy that was used for rock’n roll groups or disco set
ups.
It doesn’t have to be actual theatre lighting as Industrail, commercial & domestic lighting can be used or adapted.
Have a scrounge around Salvage Yards & even lighting stores or wharehouses, as a good source of equipment.
Possibly the best thing to do first is find an interested person, as your lighting techie.
Or at least some one who understands ‘Ohms Law’ & safe electrical
standards &/or practices. [I realise in the US there is no
requirement to have a Licensed techie/lighting operator, as we have to
have here.] However if you can get a qualified sparky on board all the
better, even just an electronics enthusiast can be of great help to the
group.
{as most Techies & Sparkies here may have come to understand that
it is not electricity that flows thru the cables, that is actually
SMOKE {Spectral Manifestation Of Emf [Voltage]} that operates
equipment, which is proved when a piece of equipment starts leaking
smoke, it invariably stops working!
Also become friendly with the you local Pro venues. Especially one you
might know is updating their lighting equipment & tender for any of
the old gear they may want to trade in or chuck out. Skip or bin diving
in their back yard can be very rewarding, especially for used colour
Gel & old bits of electrical & lighting gear.
In a lot of cases when a venue is upgrading their equipment, the supply
company of the new kit tend to smash up the old equipment & throw
it on the local tip.
Try & get in before they do & buy it off them.
Shop window display lighting is a good cheap source, such as the
dichroic spot lights that are used as domestic track lighting can be
used as well, especially as footlights [floats] mounted &
controlled individually on a wooden board.
Besides all the latest intelligent moving lights available in theatre
these days, there are still only 3 basic types of theatre
lamps/lanterns, such as ‘Profile’ [hard edge] ‘Fresnel’ [Soft edge]
& ‘Flood; lighting. The basic difference are a the Profile &
Fresnel have lens & the floods don’t. With the Profile you focus by
moving the lens the Fresnel you move the light source
[globe/bubble] to & away from the lens.
The cheap outside patio lights flood lights are useful as well, even to
make up your own ‘Ground row’ [scoop] battens & the like.
Check your local community rag or put an advert in the church
newsletter for any old lighting equipment or even for a Techie to
assist in cobbling together a lighting rig.

Gaafa ... you're a peach! Is there anything you haven't done?! Seriously, though, I live in a town of less than 500 people so I don't think I'll find any rock and roll bands or pro venues who are updating their equipment! I will go, however, with the suggestion of asking around. Perhaps a local contractor will know an electrician who'd like to help us out.

G'donya Nannette.
The only thing I have not done in theatre is to make any brass out of it & draw the line at windows cleaning,
So all in all after a few days short of 60 years - I’m a
right old failure! Although I could be older, as I have a feeling I was
a few years premature & just didn’t front up on cue - but that’s
another story.
With the electrical theory this is something which I realised when I
was about 9 or 10 having made up a series of home made ‘Salt Water’
Dimmers & a tin can lighting rig, from used food &
ingredient tin cans for my back yard shed theatre, copying the larger
salt water dimmers I had worked in the dungeon of the Grand Theatre on
Tyneside in the North East of England.
However the smoke theory was formulated & developed further by Joseph Lucas on his web site:-
http://www.peizhang.com/forfun/forfun_writings_smoke.htm
My theatre electric rig was quite spectacular.
Although I was never quite sure what all the fuss was all about at the
time? The power in the area was back on within a few minutes!
Anyhow back to your lighting problem even in a small town, by
fossicking about bit, especially at Industrial waste locations or
building refurbishment sites. You can pick up a lot of discarded gear,
even at the local municipal rubbish tip or Council Works Depot with old
lighting, cable & electrical fittings.
Or make up your own lights using proprietary brand electrical parts from your local hardware store.
One bush town I made up 8 flood units, each with 4 light fittings
in individual cells on separate circuits. That could be used as ground
rows, side or over head [Ray] lighting battens. They could be used a
separate 4 light units or plugged up into one long unit. I used two
lengths of ordinary house rain guttering, joined together to make a
trough. Divided it off in separate cell compartments using flat sheet
steal cut pieces, just pop riveted in place. Fitting ceramic ES
lamp bases in each cell & ducting the electric’s on the
outside of the base behind each lamp fittings. Running septate circuits
with a male & female plug tops on each end/circuit, which was used
to link units together or use separately on their own.
I added mounting bracket to take hanging C clamps & crossed wires
on the front of each cell to take & retain the colour gels - cheap
& easy. I think I worked it out at the time to cost only about
$11/cell + the globe.
That was 20 years ago & they are still being used at the theatre in that town today!
So with a little bit of help you can have a good lighting rig, not a very pretty - but it works in theatre.
However in all cases get any equipment that is made up or used in
theatre tested by a qualified electrician before using it &/or
‘Portable Appliance Tested’ regularly.
