Module Connected Wattage
The connected wattage (P) of an LED module measured in watts (W).
This value defines the power which is consumed by an LED module.
Luminous Efficiency (lm/Watt)
The luminaire luminous efficiency is the quotient of the emitted luminous flux and the electric power consumedby the luminaire. The value is expressed in lumen per watt (lm/W).
Module Luminous Flux
The luminous flux (Φ) of an LED module measured in lumen (lm).
This value defines the luminous flux which is created by an LED module at an ambient temperature of 25 °C.
Luminare Luminous Flux
The luminous flux (Φ) of a luminaire measured in lumen (lm).
This value defines the total luminous flux which is emitted by the luminaire.
Voltage Range
The maximum electric rated voltage, measured in volts (V), at which a luminaire is allowed to be operated.Generally Standards are 8-12 VDC / 200-240 VAC
Color Rendering Index
The colour rendering index (Ra) stands for the degree of conformity between the perceived colour of an object and its appearance under a specific light source.
Service Life
Most LED do not fail by a certain time but their luminous flux decreases over time (degradation). The service life of LED, LED modules and luminaires is limited accordingly by the total failure of their related electronic components (e. g. power supply units) or by the luminous flux dropping below a previously fixed minimum value.

Safety Classes
Safety class I
designates luminaires with an earth connection. Under fault conditions, the power supply is cut by an overload.
Safety class II
designates luminaires that, apart from functional insulation, have an additional protective insulation. Under fault conditions, no dangerous voltage can reach metal parts which can be touched. Many luminaires are available in Safety class I and also in Safety class II. Please inquire accordingly.
Safety class III
designates luminaires operating on extra-low safety voltage. They can only be connected to safety transformers in accordance with EN 61558/VDE 0570, EN 61347/VDE 712 or VDE 0100 Part 410.
