Energy Efficiency Zinex (EEI)

Various network -powered ballasts from fluorescent lamps consume of different amounts of energy and are therefore divided into seven different classes by the energy efficiency index. This index is valid throughout Europe and makes a comparison of the shifts of lights possible with regard to their energy consumption. This energy efficiency index is then abbreviated with the three letters EEI. 

It is based on the efficiency of the system Ballast/Lamps and no longer on system performance as before. So it is no longer just the system performance, but also the lamp performance. There are the following classes:

• Energy Efficiency Zinex A1 for dimmable electronic ballasts 
• Energy Efficiency Zinex A2 for electronic ballasts with reduced losses
• Energy Efficiency Zinex A3 for electronic ballasts
• Energy Efficiency Zinex B1 for magnetic ballasts with very low losses
• Energy Efficiency Zinex B2 for magnetic ballasts with low losses
• Energy Efficiency Zinex C for magnetic ballasts with moderate losses (prohibited)
• Energy Efficiency Zinex D for magnetic ballasts with very high losses (prohibited)

In the meantime, the last two classes and thus operating devices of types C and D are prohibited due to the very high energy consumption. There is also an additional abbreviation that immediately makes it clear that the best possible efficiency is available. This classification addition is BAT and stands for Best Available Technology. At lamps to Emergency lighting this energy efficiency does not apply.
