TECH TIPS
Pennies From Heaven
"C" shaped clip that snaps on to your 2" truss rail and protects it from
the angry jaws of your C clamp. Simple, and cheap. Not cheap enough, you
say? Well, what if it cost only a penny? Here's the super bargain route
(we do this MOST of the time. ): Put a penny (yes, a penny)
between the C clamp bolt and the truss. The penny is pretty trashed
afterward, but hey, you'll use it again and again, and it was previously
making a lot of noise rattling around in your glove box anyway. And even
if you do use it only once, it cost you how much? A penny!: These days,
everyone has zillions of dollars invested in miles of beautiful, shining
aluminum truss. I see so much of it come through with nasty clamp dents
and scratches, it amazes me that more people don't do this: C clips!
what are they? a simple molded plastic.
Better Console Labeling
Have you been labeling your console with expensive white electrical tape
and a sharpie, then squinting to read the labels during the show? Try
this: Black electrical tape and a fine point white paint pen. the
tape is less then one-tenth the cost of the white, and though the pens
are a little more expensive, they last longer and stay sharp longer.
More important though, is that most people find these labels easier to
read than traditional black on white. One more thing: even if you insist
on "black on white" labeling, you should NEVER use masking tape on your
console: It gums up and won't completely peel off, while PVC or plastic
tapes peel off nicely and don't leave a residue.

Tape Glue and Other Messes
Now after someone goops up your console with masking tape or your cable
with duct tape, what do you do? Well there are some terrific products
available for cleaning those nasty messes. Our favorites: HI Equipment
and Cable Cleaner (or "OJ" as we call it because it smells like orange
juice concentrate) is a petroleum based product that does just what it
says. Soak cable in it (not the connectors!) for that really old glue
residue. Also Goof-Off, a hardware store product used to clean graffiti
off walls. This stuff will clean just about anything you want it
to...and some things you don't. Be cautious as it has a tendency to take
off things like paint and decals too. When cleaning sensitive equipment
like your console top, be very careful not to get any inside the unit.
Remember that both of these products are heavy duty industrial cleaners,
so be sure to read all the instructions and follow all of the safety
warnings.
Color of the Week Award
Our old Gel of the Week (for about a year) was Lee 134. Great for
a dirty, dusty, natural amber look. This year's Gel of the Week (did you
catch that?) is not so specific. We've really gotten hooked on the new
"gels between the gels." You can find these in the Roscolux 300 series,
and the Lee 000 and 300 series. Both companies are really coming out
with some stunning new colors that we've all spent years trying to
create by color mixing and gel stacking. We just couldn't pick one to
recommend above all the others. So the real moral of the story is that
if your swatch books are out of date, you're missing out on some really
fantastic new colors!

Color Code your Cable, your Cans and your
Mother
Color code your mother? Sure, if she's hard to identify. If we own
it, you can bet we have a color code system for it. Colored
vinyl electrical tape is our friend! It is inexpensive and comes in at
least 10 different colors. A stripe around the yoke of a fixture tells
us what kind of lamp is in it. (no more opening it up to check) Various
stripes on a cable jacket near each connector tell us the length of the
cable (no more guesswork or searching for the tiny numeric length marker
most people use). A stripe around an XLR connector tells us how many
pins it has (3, 4, 5, and 7 all look the same from the outside!).
the list goes on and on.
While we generally stick with electrical tape (get it?), on some
items paint is more appropriate. The real advantage of the bright colors
is that it allows easy identification even from a distance, or in those
big messy heaps that we NEVER make! Here's our system for cable lengths
to get you started. Each color represents a basic length:
Brown=5', Orange=10', Yellow=25', Red=50', Blue=100'. Use combinations
of these colors to indicate other lengths. We put the stripes about 6"
from each connector. The important thing is to be consistent and
thorough and you won't have to do it again for a long time.

Break up on a Tight Budget
Break up gobo on a budget: Rather than a manufactured pattern, try a pie
tin or disposable cookie sheet. It should be thin enough to cut with a
pair of scissors but heavy enough to last in a 1k ellipsoidal for hours
rather than minutes. First, cut the tin to the size of your pattern
holder, then all you need to do is to drill or punch holes in the
projection area. Some crafty (and patient) souls even etch out more
complex designs using heavy cutting blades. Of course, these homemade
gobos most often will not last for more than one performance, but will
work great in a pinch.
Brand New Gobo and No Place to Put It
If you don't have pattern holders for your nifty homemade gobos (or
factory patterns), you can get by in a pinch by using heat resistant,
glass/cloth electrical tape: Simply open up the fixture and tape your
pattern to the outside shutter assembly ring (not the shutters), a trick
that will also work in Lekos with no pattern slot. Also remember that
the image gets inverted AFTER it passes through the pattern, so you can
avoid a lot of nasty burns by remembering to install all patterns
UPSIDE-DOWN and BACKWARDS!

No Hassle Fire Effects
Stop trouncing your bump buttons to produce these effects convincingly.
there are a few excellent, inexpensive products out there that are
specifically designed to do this. Our favorite is the GAM SPE-5 "Flickermaster,"
a compact little unit with several settings each for such things as
fire, television, candlelight, and gaslight. You plug your lights into
it and just adjust the settings until you're happy, then all you have to
do is turn it on each time you need it! The most effective angle for
this is from the footlight position, the soft shadows this will create
on the set are very convincing. You can also use it with 3" fresnels or
other small lamps mounted inside a fireplace unit. A specialized unit
such as this will even help modulate the fall and rise so you don't get
a strobing fire effect.
An even cheaper way to go is to use any standard chase controller
like a Deluxe Ropelight Controller. These create several different chase
patterns, but they are all very even and rhythmic. It takes some
work to get these to not look like disco fires, but it is possible. Try
using many small lamps and several different shades of amber, orange,
and light red. For this application, we recommend choosing lamps very
carefully: since the chase controller doesn't help modulate the fall and
rise, use only lamps with a slow to moderate response time, or you're
back in strobe land.
OR for a really low budget: If all you need is a practical in
the fireplace, get several strands of single color Christmas lights
(red, orange, white, yellow. whatever) and put a flasher bulb in
each. Tangle them all up and put them in the set piece so that the
actual lights CANNOT be seen (behind a grate or log unit). This effect
will only register in the fireplace, not on the actors faces, but
sometimes that's really all you need. Remember that most flashing
Christmas lights take about 20 seconds to start flashing, so plan for a
warm-up time before the curtain goes up.
A Different Kind of Backstage Light
Backstage lights...gotta have 'em, and they're always a pain! Tired of
putting blue gel on every spare lamp in the building for backstage
lights? Try Christmas lights. Just string them along where you need
them. They are great for guiding actors toward or away from things too.
Use all blue strands for those places where you're worried about the
regular work lights being too bright and bleeding onto stage. For those
super big budget shows, you could even use rope lights, if something a
little more durable is what your after.

Bench Focus those Lekos
Some users bench their lekos after every hang. If you don't already have
some sort of routine for this, you should. You will be amazed at
the difference in light output and beam or projection consistency and
controllability. Every owner's manual and lighting textbook can explain
the process, so we won't go into it here, but here is one tip: Have a
piece of galvanized sheet metal (at least 30 gauge) cut to the size of
your gel frame, but with only a 1/4" hole in the exact center of the
frame. When bench focusing, slide this into the gel frame clips of the
fixture and point the fixture at a flat white surface about 3 to 5 feet
away. You will see (once you focus the barrel) a projected image of the
lamp, filament, and reflector. You can now use standard bench focus
technique to center the lamp filament. Be warned though: Do not leave
the lamp lit for more than a couple of minutes at a time, as the plate
will get extremely hot. In fact, I have seen heat tape attached to the
top of the plate so that the plate can be handled after use.
Old Lighting Systems, Low Budget - Retrofit!
Are you working on an archaic lighting system, but can't afford to
upgrade all at once? Consider quartz retrofits: this can work for many
old fresnels, lekos, followspots, scoops, etc. just ask us and
we'll tell you whether or not you can upgrade to a brighter, longer
lasting, often lower wattage lamp and breathe new life into that old
gear.
Sharper Pattern Projections - Got a Donut?
For sharper leko pattern projections, use a donut! No, not the glazed or
maple frosted variety, but instead a "hilation blocking device." Just
slip it in the gel frame, and away goes the "halo", leaving you a sharp
image. The donut is a solid, optically opaque object (sheet metal and
heavy cardboard work great) cut to the same size as your gel frame,
except that the hole in the center is only 3 to 4" in diameter
(depending on the type of fixture). What it does is block the unused,
out-of-focus portions of the light beam that muddy up the projected
image, allowing only the in-focus portion of the light to come through
(Have you ever noticed how small and centrally located the burn spots on
your Leko gels are? This is the part of the beam that does all the
work). You will lose a tiny percentage of overall candlepower, but your
image is so much sharper that you won't miss the the minimal lost
brightness.
Stunning Lightning Effects
Lightning without strobes? Lay your hands on some very fast filaments,
like the Ushio PAR 16 JDR E26 100w lamps. these are extremely fast
to come on (rise time) and off (fall time), and while not as convincing
as strobe lights, cost a lot less and can do a lot more when not
recreating a lightning wash. They fit any standard medium screw-in
socket (there is an E17 version for intermediate or "candelabra" screw
sockets) and were especially designed to work in Kupo PAR 16 fixtures
(use E17 base) or Tomcat, Thomas, and ProCan PAR20's... OR... If you
still like your strobe lightning but are tired of trying to hang some
bulky strobe-in-a-box and use a separate controller, try a Strobe
Cannon, by Diversitronics. It's a strobe light that goes into Par64 can!
They are available in both analog and digital format, so you can run
them with almost any console. Best of all you can easily put a gel in
them. Think of the possibilities! They also come in a version that
fits in most Lekos, for projection lightning bolt patterns. See WHITER
WHITES for a lightning color tip.

Brightest Light from the Smallest Package
Small package, big result. There is without question no better,
economically sound way to get clean, crisp footcandles (and a lot of
them!) out of such a tiny package than with the PAR 16 and PAR 20-120v
fixtures being produced these days (see tip above). Personally, I prefer
the PAR 20 for its added sturdiness and standard socket; this way the
fixture as well as the lamp do not become "one-trick ponies." These
units work well with the mini C clamps and floor bases commonly used on
3" fresnels. They can also be gaff taped or stage screwed in place on
sets and flats, even props. They take gel frames, barndoors, and are
only about 7" by 3.5"! One warning. since these fixtures put out a
lot of light, they also burn fairly hot, so some care is necessary to
keep them protected from heat sensitive objects. I have used these
lights hundreds of times for everything from wall and set grazers to
plant uplights to product reveal specials. I have even seen them used in
small clubs for bands and dance floors, in the living rooms of the rich
and famous as artwork illumination, and too many other uses to mention.
The best part? They are very inexpensive, and the lamps are rated at
2000 hours. Remember, "versatility" is the buzzword, and "lots of bang
for the buck" is the result.
Higher Wattage does not Mean Brighter Light
With all of the advancements being made in theatrical crafts these days,
not only do we all have to learn new ways of doing things, but sometimes
even new ways of thinking about the things we do. On the lighting end,
many people are confused by all the new lamps on the market. As you
learn about these new lamps, don't be fooled by the strange wattages you
see. For instance, the HX600 lamp is a 575w replacement for an EHD, EHG,
or FEL. So why would you want to replace your nice bright 1000w FEL's
with 575w lamps? Well, for one thing they're brighter...really, they
are...for another you can put 4 of them on a 2.4K dimmer with 100w to
spare for safety's sake. They also put off less heat and will go easier
on your gel and gobos.
There is also a long life version, the HX601 that has a lower color
temperature, but is rated for 1500 hours! And if you are looking for a
spotlight, you might be surprised to learn that even though you can
still buy a 1500w incandescent spotlight, a 1000w quartz spotlight is
almost twice as bright! And a 360w enclosed arc spotlight is almost
twice again as bright as the 1k quartz! The secret is in the efficiency
of the filament. The smaller the point of actual light emission, the
more optically efficient the lamp will be. A tiny pinpoint of light from
an enclosed arc lamp can easily translate to many times the brightness
of a large conventional filament lamp. Never again judge a lamp by the
wattage in the catalog. Look at the other information (called "Photometrics")
like lumens, lumens per watt, and color temperature. And when in doubt,
ask the experts at Hollywood Lights!

Color and Color Temperature
Have you ever tried to pick gel colors outside? Or by looking out a
window? If so, I bet you were in for a shock! Daylight has a much higher
color temperature than the incandescent fixtures used in lighting. What
that means in practical terms is that none of your colors looked like
the ones you picked. Sunlight renders colors with much more blue than
incandescent fixtures, which tend to yellow the colors. So be sure to
pick colors using a light source with an equivalent color temperature to
the fixture you're planning on using.
Whiter Whites
If you light rock bands in night clubs and can't figure out a way to
make your no-color fixtures look crisp and bright while keeping them
from trampling your darker colors, do what the pros do: Raise the color
temperature! Try any CTB correction filter; my favorite is 1/4 CTB such
as Lee 203 or Rosco 3208. There is a wide range of blue correctors out
there; experiment to find the best one for your palette. This is
also a great way to make lightning effects more vivid and realistic,
because there's nothing worse than dusty yellow lightning bolts, right?

The Hazemaker Craze
We have been struggling with actors and musicians for years to get them
acclimated to (or even to permit the use of) chemical smoke or fog
machines, which as many of you know are an absolute necessity when using
intelligent lighting such as Roboscans and Intellebeams or other special
effect fixtures such as those used in dance clubs. In many cases, it
takes an act of Congress and hours of labor to create particle matter
thick enough for those neato beams to be visible, yet thin enough not to
overpower the stage and make the on-stage talent vow your demise.
What's worse is that it isn't really a wall of smoke you need; you
really only want a light haze to give the lumens something to bounce off
of! Here's what to do. If you can afford to rent a high end smoke
machine, you can probably afford to rent a "haze machine." This is a
technology that until very recently has been so costly that only the
largest touring shows could afford them. Now there are several
commercially available options that are much less expensive; our
favorites are the Rosco Hazemaker and the SFX DF50. These machines put
out a terrific, long lasting mist that is totally inoffensive (in fact
barely noticeable) to the performer and doesn't look like the stage is
on fire, yet it shows off those beams very well. The new machines are
small (traditional hazers were enormous), light, and use fluid very
slowly. In most cases, they do not even require remote controls, you
simply turn them on at the top of the show, and off at the end.

The other bonus of the DF50 in particular is that instead of using
expensive fog fluid, you can stroll into your local Safeway and pick up
a bottle of Mineral Oil for about 98 cents per pint! A word to the wise:
If you're picking out a hazer, be sure to turn it on and listen to it
first. some of them are still a little noisy, which is no big deal
in a night club or at a loud rock concert, but could really spoil a
quieter show. Some of the noise can be eliminated by placement, but know
what you're getting into when you walk out the door with it.
It's All Done with Mirrors!
In order to get more stage coverage out of your moving mirror fixtures,
hang them sideways on the pipe with the mirror facing down. The fixture
can then usually pan all the way upstage to hit the backdrop, and all
the way downstage to hit the audience. Most tilt ranges are wide enough
to still allow the fixture to see all the way stage left and right too.
This will be a little confusing to program at first (unless your
operating system allows you to swap pan and tilt channels), but you'll
quickly get used to it, and the resulting enhanced projection range is
well worth it.
Eliminate your DMX Nightmares for Good
DMX jitters? Crosstalk? Unreliable results from console to digital
device? In laymen's terms, what may be happening is this: The digital
signal created by your console travels down the control line to the
input of the first device (say, your dimmers), then daisy chains to the
next (say, your colorscrollers) and on to the next (like a strobe or fog
machine). Once the control signal has fed through the last device in the
chain, let's just say it "ain't done talking." What happens is that the
signal, seeing nowhere to stop, will turn around and head back to where
it came from on the neutral conductor of your DMX cable, creating a
feedback or reflection and, of course, confusion amongst your equipment.

To solve these problems, the signal needs to stop at the end of the
line. Here's a solution that may help you avoid the often costly
purchase of one of the myriad of "DMX fix" boxes currently available,
and is far less expensive than Arnold Swartzenegger: Build yourself a "DMX
Terminator!" All it takes is a 5 pin male XLR connector (cable mount)
and a 100 to 125 ohm resistor soldered between pins 2 and 3. plug
this little gadget into the pass-through at the end of the control path,
and you are now officially terminated. We terminate every DMX signal we
send, no matter the distance. Since terminators are so small and
precious, we recommend attaching a piece of string or tie line and
wearing them around your neck to avoid loss, and to keep from being
inadvertently tossed in the XLR connector bin with other connectors that
look identical but don't have the magic resistor installed.
Create Smoother Automated Cues
"Ban the Blip!" I'm talking about the annoying flash of light that
occurs with most intelligent lighting at the top of the cue, the result
of the mirror, gate, and color wheel looking for its "mark." Here's how
the pros fix it: Add an additional step to the beginning of the cue
sequence. I call it a "set up." The step should contain all of the
mirror, color, and gobo information that the first look contains, only
with the gate closed (and for certain systems, the dimmer at "0"). This
way, all the "rushing around" takes place with the "curtain down."
Easy, All Purpose Storage Tip
Raid the kitchens of your favorite local restaurants for 2, 3, and 5
gallon buckets. These are very, very handy for hard to store and hard to
transport loose items from clamps and hangers to bolts and pins or
adapters and jumpers, you name it. If you can't find a restaurant that
wants to part with any, they are still very cheap to buy (especially in
quantity) from a container or janitor supply warehouse. You can even get
lids or wheels if so inclined. And if you want to get really
fancy, we can set you up with a heavy duty canvas bucket that has tool
pouches all the way around the outside. One of our big drool items
around here!
Vacuum your Dimmers
That's right. if you don't already, you should! All dimmer packs
and racks that are air-cooled by a fan or series of fans are subject to
an enormous (and enormously destructive) buildup of dust and grime, most
of which can be extracted by a vacuum with a narrow nozzle attachment.
We also use a small compressed air tank (or an air compressor if
available) with a blower valve and a needle attachment to power cleanse
the stickier dust and tighter corners. This procedure, when done
routinely, will save you hundreds of dollars in repair and countless
hours of frustration.
If you don't keep the dust build up out of your dimmers, it is only a
matter of time before one of any number of nightmares ensues: The dust
does two things. first, as it builds up on the parts of your
dimmer, it insulates them from cooling, causing them to overheat and
malfunction. Second, it can in many cases (especially when mixed with
moisture from a humid environment) become a conductor of electricity,
creating any number of short-circuit scenarios within the unit. All of
these things spell doom, gloom, and despair for your dimmer pack,
without which your show can't continue (you didn't think they'd
conveniently break down a whole week before opening night, did you?). So
keep 'em clean!
Extend Lamp Life
Here's an old fangled trick that should never be forgotten for those of
you who work in environments that are less than comfortably warm, like
outdoor situations in sub 50 degree temperatures, or in that drafty old
building that takes the first 4 hours of each day to get cozy: Warm your
lamps slowly! It is a shock and a detriment to the filaments of most
lamps to go from mighty-cold to really-hot in just the time it takes you
to romp on the bump button or snap the fader to full. If they are cold,
SLOWLY run them up to 15 or 20% for at least 30 seconds before running
them at full. The lamps will repay you with a much longer life than if
otherwise jolted awake. This is a great habit to get into. Insert a
warmup cue at the top of your cuestack; that way you'll never forget.
Source Four/Shakespeare Lens Alert
For those of you who conscientiously clean the lenses of your fixtures
every so often, (and you should) be aware that although the glass lenses
of most fixtures react beautifly to glass cleaner and a paper towel, the
lenses in the new ETC Source 4 or the Altman Shakespeare fixtures WILL
NOT! The lenses on these new fixtures are coated in a special heat
resistant coating. This coating will scratch and become cloudy if
cleaned with glass cleaners, ammonia products, abrasive cleaners or
cloths, or paper towels. Use only gentle soap or lense cleaner and a
soft non-abrasive cloth.
Turn Heads the Easy Way
If, like us, you have fallen headlong into the world of moving-head
intelligent lights, you may have noticed that it is not always easy to
tell (at a glance) which side is front or back on these things. This is
especially true with the Martin MAC fixtures. We solved the problem by
putting a small red dot on the back of the body and the head, so that we
know which way to mount them and can then avoid running out of Pan
range.
