Full Spectrum Lighting: Ghost Hunting!
Full Spectrum Lighting
Full spectrum lighting used for illumination of full spectrum cameras for ghost hunting
has been confusing to say the least. What lighting should be used? What wavelength or
band of light works best? Is there a range of light that is best to capture the photos of
ghosts? We'll explore all this in this article about full spectrum lighting.

Full Spectrum Lighting: AC Versus DC
Full spectrum lighting to illuminate the darkness to invisible spectrums can be achieved
using different types of lighting. Many ghost hunters are aware of Infrared (IR) light sources
for video cameras. Recently, some ghost investigators have been creating
battery-powered lighting that incorporates both Infrared and Ultraviolet LED light bulbs
specifically for full spectrum cameras. We want to explore another alternative:
incandescent full spectrum lighting utilizing A/C power. Having battery powered full
spectrum lighting, or even IR lighting, is wonderful to have as an option for where A/C
lighting is not possible. Angels & Ghosts Store:  Infrared Lighting

A/C powered
full spectrum lighting has a distinct advantage over battery-powered LED
lighting, that being stronger illumination to the eye of the full spectrum ghost hunting
camera. Low watt, A/C bulbs can easily brighten an area as long as 50 feet or more. Add a
spot light-type bulb with greater wattage, and you have a powerful light source that can
broadcast rays even further. Like the LED type full spectrum lighting that is popping up at
the time of this article, incandescent bulbs can be used to delineate a range of light for the
camera to see.
If we choose to use an Infrared light, primarily the
Near Infrared range of the electromagnetic
spectrum will be visible to the full spectrum
camera. Most of the visible light will be blocked
out by the red tinted glass of the IR bulb itself.
Similarly, by using an incandescent black light
bulb, most of the visible light is also filtered out but
the dark blue colored glass allows the emission of
both Ultraviolet and Near Infrared light. This gives
the investigator of the full spectrum camera the
option of using the type of lighting to explore the invisible spectrum of light he or she
prefers. The user must be aware that these light bulbs should be used in sockets with heat
shields. They do become very hot.
Full Spectrum Lighting: About Light Bulbs
An incandescent black light bulb to be used
for full spectrum lighting is similar to the
normal light bulb used in lighting our homes. In
fact, regular incandescent light bulbs put out a
full spectrum of light: some UVA, visible light
and some Infrared (they get hot). The black
light bulb uses special light filters to absorb
the light from the heated filament, capturing
most of the visible light but not the Infrared
(heat) or the UVA. It is the UV light that
causes posters and other things to fluoresce -
glow when exposed to black lights.
Infrared light bulbs are used to create heat with an internal reflector, coupled with a red filter
to minimize the emission of visible light. They should be used in a ceramic socket (instead
of plastic) to withstand the heat. For ghost hunting, use a lower watt Infrared bulb (50 watts)
to reduce the amount of heat generated by the light. Infrared lights are used to warm reptile
cages and can easily be found at most pet stores. When choosing a black light bulb, the
fluorescent tube-type will not work as well as the good old incandescent bulb.
(By the way,
there are light bulbs called "full spectrum bulbs," but they are for reproducing light that
appears similar to natural light. They are used for artists and photographers to work with.)
Full Spectrum Lighting: Illuminating What You Want, Eliminating What You Don't Want!
Some makers of full spectrum cameras claim that the camera must have the visible spectrum filtered out,
otherwise, the white light will "wash out" the UV and IR light. We do not feel this is true and feel it best to allow the
camera to be able to see as much as possible. A true full spectrum camera has the sensor unfiltered and
wide-open. However, if an investigator chooses to focus on a certain type of light for ghost photography, then we
believe that choosing the correct light source for dark environments will filter the camera's eye accordingly. In other
words, the true full spectrum camera will be able to see the wavelengths of light emitted by the light source itself.

Full Spectrum Lighting: Where Are Ghosts Found?
What light source is working best for ghost investigation, Ultraviolet or Infrared? We are seeing evidence that
ghosts are being captured by cameras in shorter wavelengths, meaning the Infrared spectrum. More
experimentation needs to be done, but it does appear that more visible ghost manifestations are occurring within
the Near Infrared and visible spectrum. Full spectrum cameras that have the visible spectrum filtered but allow both
the IR and UV bands to be seen by the camera sensor have also been capturing some intriguing images. In our
opinion, this does not prove that ghosts manifest in the Ultraviolet light. To us, it simply suggests that ghosts can
appear in the Infrared spectrum; most ghost investigators are not using full spectrum lighting. The typical
investigator is using only IR lighting but achieving good results.

We compared the light
emitted by both the UV
(75 watt black light)
and IR (50 watt heat
lamp) bulbs. Both
bulbs illuminated the
40' long room quite
nicely for our 10.1 mp
full spectrum camera.

Looking at both bulbs
on, the black light bulb
looks purple and the
heat lamp bulb looks
red (below). These are
mounted in clamp
lights and can be used
in conjunction with one
another, depending on
whether or not we
prefer just Infrared or
the combination of
Ultraviolet with Infrared.
