The freedom to set the tone
Lighting oers so many possibilities for the illumi-
nation of spaces, scenes and objects. With the rich
variety of our reector lamps, you can set the tone
you want.
Reector
Lamps
Whether as a ceiling or wall spotlight - Toshiba
reector lamps are available with various beam
angles at the desired lighting levels and with
plug-in or bayonet plugs. Just as you please.
The consumer will have to get used to working with dierent units - lumens instead of Watts -
the EU Directive will make a considerable contribution to the ecological protection of our environment.
We are pleased to be making this journey with you.

GLOSSARY
Basic Photometric Units
There are several photometric base quantities in the definition of
light sources, which characterise different qualities.
Luminous flux ϕ in lm (Lumen)
The total radiating power emitted by a
light source, which the eye perceives as
light.
Luminous intensity I in cd (candela)
The luminous flux of a light source per
solid angle. With the same luminous flux,
the light intensity increases the more the
light source focuses the light.
Luminance E in lx (Lux)
A measure of lighting power per lit
surface. A minimum luminance is
specified for many visual tasks and must
be considered in the planning of the
visual task and choice of light source.
Colour Rendering Index Ra
Colour Rendering Index (CRI) is a measure of how well a light
source is able to accurately reproduce colours of objects being lit
respective to the colour temperature (CCT) of the light source. The
higher the colour rendering index, the more naturally the colours of
an object are reproduced and therefore perceived by the observer.
The sun has the highest CRI of 100. Most artificial light source
are below that. The colour rendering index is determined using
8 standardised test colour references.
Dimmability by trailing edge phase control
Pack Omni, Pack Accent and E-Core 1100 and
1600 luminaires can be dimmed very easily using
trailing edge phase control. The advantage of trailing
edge phase control compared with circuits in which
the voltage is controlled by a resistance is that they
have a very low power loss and are widely used in
existing installations. The main disadvantage of trailing edge phase
control is the non-sinusoidal current profile. Because current
and voltage do not have the same shape, so-called distortion
reactive power occurs. Shifting the current backwards compared
with the voltage curve has the same effect as an inductive load,
which electricity supply companies can only tolerate at low
power levels. Leading edge phase control is not recommended
for Toshiba lamps. Because there is no general compatibility
between all dimmers available on the market, Toshiba
has provided a list of recommended dimmers on its website
www.toshiba.eu/lighting.
Colour temperature (K Kelvin)
Colour temperature is a measure of the colour effect of a light
source. Colour temperature is defined as the temperature of
a black body which belongs to a particular light colour of this
emission source.
Typical colour temperatures for light sources are:
• below 3300 K = warm white, preferred for interior lighting
• 3300 K to 5300 K = neutral white, typical light colour for office,
industrial and exterior lighting
• above 5300 K = cool light, especially common in exterior lighting.
L70 service life of LED light sources
LEDs are characterised by their excellent service life. Because
LEDs hardly ever fail completely, the service life is defined as
having an L70 value. Their useful life is considered to be over when
the luminous flux has dropped to 70% of the initial luminous flux.
After this time the LEDs age at a dramatically accelerated rate.
The service life of an LED light source is not set by the LEDs alone,
the other electrical components and the thermal design are also
a factor. Therefore the given service life varies from product to
product.
Performance factor λ = cos ϕ
The LED light sources need driver modules to operate which act
capacitively from an electrical point of view. This leads to a phase
shift between voltage and current consumption and consequently
the apparent power S (given in Volt Amperes VA) has an effective
power proportion P (Watts) and a reactive power Q (Volt Ampere
reactive VAr). The relationship between effective power P and
apparent power S is represented as the performance factor λ.
