The freedom to set the tone

Lighting offers so many possibilities for the illumi-

nation of spaces, scenes and objects. With the rich

variety of our reflector lamps, you can set the tone

you want.

Reflector

Lamps

Whether as a ceiling or wall spotlight - Toshiba

reflector 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 different 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.

Rated lamp luminous flux ϕ [lm]

Traditional Wattage:

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

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.
