Positioning Black Lights
Since UV light is not very strong and doesn't travel very far, its important to use the
right strength and size black light tubes
or twist black light bulbs
to illuminate your Halloween decorations, props, etc.
Use smaller twenty-four inch size lights for smaller area's and displays where you can
position the unit in close. Use larger four foot units to cover large areas, scenes and
props. The darker the room or area, the brighter the
fluorescent material will glow.
As with any electrical device, care must be taken to
protect against electrocution and accidents. Make sure that the cord is hidden from view
and positioned where it won't be tripped over or snagged by your
visitors feet. No electrical fixture should be used
outdoors if the weather is bad, i.e. raining, very high humidity, etc.
Directing Ultraviolet Light
Most
of the time you will need to direct the black light
into a particular area or directly at a particular Halloween decoration or prop. Fluorescent
Twist black light bulbs
work
great when placed in a metal parabolic housing such as a "Clamp Lamp" when
you need to direct the black light in this way. Clamp Lamp fixtures like the one
pictured to the right can usually be purchased
in the hardware or lighting section of most department stores.
Its important to remember that this method will only allow you to better
direct the black light, but will not extend its
useable range. We usually paint the outside
of our Clamp Lamp fixtures with flat black spray
paint to better conceal them.
Camouflaging Black Light Units
Whenever possible the black light unit
should be positioned and/or camouflaged so that it
cannot be seen by your visitors. While people can see the purple colored
glow from the black light bulb its self, they cannot
see the ultraviolet light that actually emanates
from it. In most cases you will want to hide or
camouflage the bulb and unit it is in, so that
people will not be able to see the source of the
black light. You can also use bricks
arraigned to for a visual barrier. A section of
inexpensive metal eave trough (rain gutter) material
works well for hiding single bulb units, but is
usually not wide enough to hold a double-bulb unit. There are several
safety considerations to keep in mind.
Black
light units, like any electrical device, do generate
heat and should not be placed near or attached to
any material that could catch fire, such as wood,
plastic, fabric or paper type materials. As mentioned
above, the cord and any extension cords you might
need to use should be placed wear people will not
trip over them.
Glow in the Dark Dye
If
you need clothing, sheets, cotton rope (rope spider
webs), or other fabric to glow a bright blue in the dark, you can
soak it in "RIT
Whitener/Brightener". This happens because of the
natural reaction between the phosphor's in
the whitener/brightener and the ultraviolet light.
This works best on white
or light colored fabric. To do this simply fill a
container, such as a plastic tub with enough water
to completely cover the items you want to glow. Mix
in a box of "RIT Whitener/Brightener" and stir until
it is dissolved. Immerse the items into the solution
and let them soak for about an hour. Don't rinse it
out, simply wring it out and let it dry.
Glow in the Dark Spray
"Glow in the Dark
Spray", manufactured by
Fun World is
suitable for painting Halloween decorations, props
and even costumes to make them glow. This spray is a
type of water-based paint and will visibly coat the
prop or decoration with a pale yellow coating. This
coating will glow in the dark the typical
greenish-yellow color when exposed to ultraviolet
light. Be sure to spray the paint onto the object as
evenly as possible. It helps to spray the paint on
while the prop is under a black light so that you
can actually see where the paint is being sprayed.
We use this spray on some of our Halloween props,
such as skeletons, to add extra effect. Be sure to follow the use and safety instructions included
with this product closely.
Black Light Hairspray
Not
to be confused with the product above,
"Glow in the Dark
Hairspray", also from
Fun World,
works very well for painting Halloween
decorations when you don't want the paint its
self to be visible. It goes on nearly invisible and should be sprayed onto the prop as evenly
as possible. It helps to spray the paint on while the prop is under a black light so you
can actually see where the paint going. We use this spray on some of our
tombstones and Halloween decorations to add an extra effect. This spray
can also be used as hair spray to make your hair
glow in the dark.
It will dry
invisible and should be sprayed onto
your hair as evenly
as possible. Be sure to follow the use and safety instructions included
with this product closely.
Fluorescent Paint
Fluorescent
paint fluoresces brightly when exposed to
ultraviolet light and is available in a variety of colors
including Yellow, Green, Blue,
Red and Orange depending on the particular pigment
that it contains. A different version, invisible
fluorescent paint, looks white or clear under normal
light, but glows brightly under a black light
source. Fluorescent paints are
great for painting your props to enhance them and creating
fluorescent Halloween decorations. Most fluorescent paint is
water based, but is available in oil base as well if
needed. Unlike phosphorescent paint, fluorescent
paint stops glowing the moment the black light
source is removed.
Phosphorescent Paint
Phosphorescent
paint is most commonly called "glow-in-the-dark"
paint. Not to be confused with fluorescent paint as
discussed above, this paint is manufactured with
phosphors that have the ability to absorb light and
typically glows pale green in color, but is also
available in tinted colors as well. Unlike
fluorescent paint, this type of paint will continue
to glow in the dark for anywhere from minutes to
hours after it has been exposed to light, but will
eventually fade out.
Glow
Inc.com specializes in the manufacture of high
quality, extended glow phosphorescent paints that
are up to twenty-five times brighter than regular
retail glow in the dark paint. Their solvent-based
glow in the dark paints can be recharged millions of
times using almost any light source.
