Wall Cabinet Signs
Our illuminated wall
signs are manufactured and installed to Underwriters Laboratories, National Electrical Code (National Fire
Protection Association), and City Code standards using UL
components and either "High Output" 800MA fluorescent or
H.I.D. lighting; depending on the size and shape of the
signs, component cost, and the resulting electrical
H.I.D. lamps in our signs are
screened by proprietary lamp diffuser panels so
that the sign faces light evenly.
fluorescent burn brighter than standard fluorescent, and
most importantly burn evenly in cold weather. H.I.D.
lighting does not dim as much as fluorescent in cold
weather. Both will light a sign equally when
fluorescent ballasts use less than half the energy of
standard ballasts, and have proven their reliability.
This is why we now use them! See our "Energy
Savings" tab under "Lighting

H.I.D. ballast's used by Signs Manufacturing™ feature a

test each ballast on every secondary wire to insure proper
cathode heating voltage on the Rapid-Start Circuit.
If this test is not performed, even though the lamps may
light, they may not last 3 months. (We also perform this
test when we install new lamps in a customers used sign.)
To insure the
electrical integrity of our signs, each lamp socket is
individually tested to insure that it has been properly
wired, since it is possible to wire a sign improperly
and still have the lamps light (for a short time).
We also test every competitors sign when we perform
maintenance for the first time.

If neon is
incorporated into the sign, glass neon electrode housings
are employed wherever possible to increase reliability and
improve the appearance of the sign.

function their best, these transformers need their
electrical circuit to have a grounding conductor.
All modern buildings have them. These transformers also
require a dedicated common wire so that other devices,
like a refrigerator turning “on”, on the same wire circuit
does not turn your GFI transformers “off.” If your
building is not wired properly you will want to have it
corrected, so that your sign will work reliably.

ALL other transformers these U.S. manufactured
transformers contain a "Smart" microprocessor that
automatically tries to reset the ground-fault before
shutting down the transformer. If the fault was only
momentary, the transformer will remain "on," illuminating
your sign. These transformers also automatically
reset when their power is turned off and then back on.
They offer our customers the greatest opportunity to avoid
Our newly-developed energy-saving in-series transformers

calls caused by neon transformer outputs as high as 15,000
supports and porcelain insulators will be used because
they do not degrade over time, unlike the plastic and clay
components used by some.
LEDs are very sensitive to voltage. The power supplies we use to power LEDs provide internal overvoltage, low voltage, spike and brownout protection for the sign. Many manufacturers do not.
Please stop by and see all of these products displayed in our unique Sign Lighting Laboratory and Display Showroom.
Optional Electrical Surge and Lightning Protection
Electrical surges on a sign’s incoming power supply, and lightning strikes, are not covered by any manufacturer’s warranty, and they are common in Texas.
As technology has moved us from the use of electrical components such as core-and-coil ballasts to electronic components, primarily to reduce power consumption, the susceptibility of a sign to damage from electrical power surges or lightning strikes has increased dramatically. Old-style electrical components are simply no longer available in most cases.
Signs Manufacturing™ offers surge and lightning Zap Protection™, at a reasonable additional cost, adding components to signs to lower the potential for damage from an occurrence.
