Introduction
The byko-spectra mini is a compact light booth
which provides colorists, stylists, designers and
color technicians with the three most common
types of lighting: daylight, office, and incandescent
illumination.
The user can create a viewing environment that
simulates the typical lighting conditions in a store,
office, home, or natural daylight. The byko-spectra
mini presents color samples and materials within
a controlled neutral gray (Munsell N7/) surround,
which eliminates color contrast and distortion
caused by non-neutral surface reflections, or non-
standard ambient light.
Important
This product was carefully inspected and checked
before it was packed and shipped. Examine it
thoroughly for apparent or concealed damage. If
damage is discovered, call the trucking company
or deliverer to arrange for an inspection and
initiate a claim for damages.

4- 3/8” Thumb screws
Assembling the the byko-spectra mini
Step 1
Begin by sliding side panels over the channel of
the rear panel (as shown).
Step 2
Next, place viewing surface into booth as shown.
Secure viewing surface to booth using four (4) 1/2”
thumb screws provided.
Note: It is easier to install thumbscrews when unit
is ‘leaned back’ onto rear wall.

Setting Up the byko-spectra mini
Setting Up the byko-spectra mini
Place your byko-spectra mini on the table, desk,
or work surface where it is to be used. Before the
line cord is connected to a power source, check
the product specification plate on the rear of the
booth, to make certain that the electrical rating
matches the power supply.
Normally, the daylight source is used as the
primary source, and the Cool-White, TL84, or
Incandescent sources are used to check the
integrity of the color match.

Operating the byko-spectra mini
Operating the byko-spectra mini
The byko-spectra mini light booth system comes
with three rocker switches to switch between
the three lighting conditions. The three lighting
conditions are represented by symbols and are as
follows:
NOTE: You should only have one source turned
on at one time
When the switch with this graphic is turned on, the
Store Light (CWF / TL84) is on.
When the switch with this graphic is turned on, the
Incandescent or „Home“ light source is on.
When the switch with this graphic is turned on, the
Daylight Fluorescent light (D6500) is on.

Adjusting for Sample Brightness
Adjusting for Sample Brightness
For optimum viewing of color samples, dark
materials require more light, and light materials
less light. When viewing very dark materials, the
sample(s) should be raised closer to the light
source and moved away from the source when
viewing light samples. As a „rule of thumb“ very
light materials should be placed at the bottom of
the booth, material of medium lightness should
be raised approximately 13 cm (5 inches) from
the bottom, and very dark materials raised
25.4 cm (10 inches) from the bottom. This is
an approximate light intensity range of 100 to
200 footcandles, covering virtually all viewing
requirements.

Detecting “Metamerism”
Detecting “Metamerism”
When two color samples match under one light
source, but not under one or more other light
sources, the “color-match” is metameric. This
means that the colorant formulation in one sample
differs from the formulation in the other, resulting
in differing spectral reflectance factor curve
shapes. A metameric color match can also be
referred to as a “conditional” color match, since
the quality of the color match is conditional to the
type of light source under which it is viewed.
While it may not be possible, with the colorants
available, to completely eliminate metamerism,
the byko-spectra mini provides colorists with
the means of visually “indexing” the degrees of
metamerism under three spectrally dissimilar light
sources. The formulation may then be adjusted
to provide the “best match” under a specified
lighting condition, or the least metameric match
under all three lighting conditions.
For obtaining the best correlation with instrumen-
tal measurements, calculated color differences
and metameric indices, the spectral power
distribution of the sources in the booth should be
used in the computations.

Maintenance of the byko-spectra mini
Maintenance of the byko-spectra mini
NOTE: Disconnect the power cord before
cleaning or relamping the byko-spectra mini!
Cleaning
The viewing area of the byko-spectra mini should
be kept clean and free of samples, notices, etc. To
clean the neutral gray surface, use a soft, damp
cloth with a mild soap or detergent. For stubborn
marks or stains, use a non-abrasive “soft-scrub”
type of cleaner. DO NOT use organic solvents on
the surface.
When to Relamp the byko-spectra mini
In order to maintain proper color quality and light
intensity, the lamps should be replaced after 2,500
hours use. It is important to use a BYK-Gardner
daylight source when relamping. To order replace-
ment lamps for your light booth, refer to the
product label on the rear of the unit (located near
power cord) for a relamp kit code.
Replacing the Lamps
Rotate the lamp 90 degrees to remove it from its
lampholders. The tubular incandescent lamp has a
screw-type base, which unscrews like a standard
incandescent bulb. After removing the lamps, wipe
the polished reflectors with a soft, damp cloth,
to remove any accumulated dust. Install the new
lamps into their appropriate sockets.
Fluorescent Lamp „Flicker“ Note
The fluorescent lamps may flicker or „spiral“ when
new. This is a common characteristic of new
fluorescent lamps and does not indicate that the
lamps are defective. Normally, flickering gradually
diminishes then disappears after approximately 50
hours of operation. Flickering can be eliminated
more rapidly by (1) turning the light booth on and
off, rapidly, a few times or (2) by removing the

English
Maintenance of the byko-spectra mini
lamps and reversing them end-to-end so that the
pins go into the opposite sockets.
Extended, or chronic flickering can also be a
result of the light booth being connected to an
ungrounded outlet or to a „noisy“ electrical circuit,
e.g. a circuit with a photocopier or other device
with high power requirements connected to it. To
eliminate these causes of flicker, make certain
that your light booth is connected or wired to a
properly grounded outlet or reconnect the light
booth to another circuit which is known not to
have high-powered devices on it.
Fluorescent Lamp End Blackening
Ignition filament deposit during operation can
cause lamp blackening(banding, spots) at the
ends. This is a normal condition and will not affect
the light quality or operational performance of your
light booth.
Disposal
All fluorescent lamps contain small amounts
of mercury. Please dispose of lamps properly
according to Federal, State, and Local regulations.

Allgemein & Wichtig
Allgemein
Die byko-spectra mini ist eine kompakte
Lichtkabine, die Farbhersteller, Stylisten,
Designer und Farb-Techniker mit den drei
meist bekannten Lichtarten versorgt: Tageslicht
(D65), Kaufhauslicht (TL84 oder CWF), und
Glühlampenbeleuchtung (A).
Der Benutzer kann eine Betrachtungsumgebung
simulieren, die den typischen Beleuchtungs-
bedingungen in einem Kaufhaus, Büro, Zuhause
oder dem natürlichen Tageslicht entspricht. Die
byko-spectra mini bewertet Farbmuster und
Materialien innerhalb einer kontrollierten, neutral
grauen (Munsell N7/) Umgebung. Durch die
nicht vorhandene Reflektion von Oberflächen
und die Abschottung von Fremdlicht werden
Farbkontraste und Farbverzerrungen verhindert.
