Dichromatic
Light Bulbs:
(Green, Blue,
or Amber)
Why
Photobiology?
Important hormonal and neurochemical brain rhythms are maintained
by fluctuations of light intensity and spectrum (color frequency).
Certain nerves from the eye (retina) go directly to the
pineal (hormonal regulating center) and hypothalamus (deep
brain regulating center). These nerves have nothing to do
with color perception; they have to do with deep brain rhythms.
These nerves are the analogue of the Harderian gland found
in other species. Recent research in mood show changes with
seasons or circadian (timed) rhythms. Other studies suggest
that seasonal depression may be reduced by exposure to appropriate
light sources, e.g., Dichromatic light. |
Why
Dichromatic light differs?
Dichro-color lamps employ internal dichroic interference
filters to selectively “separate” the energy
radiating from the filament. These filters are composed
of materials with different indices of refraction in alternating
layers. The filter replaces the bright aluminum coating
found on the reflector surface of standard PAR (flood)
lamps allowing both visual and non-visual pathways to
be employed. Deep brain structures and chemical pathways
can adapt toward improved health by using this form of
light as suggested below.
The
dichroic filter is on the inside surface of the bulb lens.
Reflector surfaces have a bright aluminum coating. The
filter produces a specific color by selectively transmitting
only the desired wavelengths of light, with virtually
no heat absorption. Light of the other wavelengths is
reflected back into the lamp. Colors are richer and clearer.
In contrast, standard, pigmented color bulbs create the
illusion of color by frequency subtraction. The actual
color wavelengths are not created. Standard ‘colored
lights’ do not have the same health benefits.

Setting
up the Dichromatic Bulb. What else do I need?
A clamp fixture (porcelain, with a shroud or sleeve to avoid
heat contact with the base or back of the lamp, found at
most hardware or lighting stores for about $15) rated for
150+ watts is suggested. Positioning the lamp should be
easiest with a socket-clamp fixture. |
How
best to benefit from the Dichromatic Bulb?
The person sits four to six feet away from the face of a
green light for 20 minutes, twice daily. This is typically
done in the morning and early evening. The person might
plan to use this time for deep breathing (abdominal breathing),
relaxation reflex, guided imagery, range of motion exercises,
or peaceful reading. The person need not (and may find the
bulb too bright) to look directly at the light. Green, a
balancing color, may be used as much as desired. |
Use
of Other colors: other than Green
If indicated, or directed by health practitioner, amber
(yellow) or blue dichromatics can be arranged to shine on
the face, back, chest abdomen or any other specific area
of the body. (Amber or blue dichromatics should not
be used for more than 20 minutes twice daily).
The same four to six feet position and time conditions apply.
Several lights can be used simultaneously. It is best if
these are the sole source of illumination. |

Bulbs, when in use, are quite warm, so extreme caution
is suggested.
