PowrMinistor Used for Lighting Control of Malaysia
This 864-seat concert hall sits between and links the two 88-story Petronas Towers (Twin-Tower), a magnificent new landmark dominating the center of Kuala Lumpur. The acoustic volume of the hall can be changed by a unique reflective ceiling which can be moved to accommodate a varied range of musical activities. The hall also contains state-of-the-art audio-visual and broadcast systems. It is a world-class venue for music, Malaysian cultural performances, public meetings and conferences. The hall opened in 1998.

[6] Data analysis: From the above data, the power saving rate is calculated as follows:
Power saving rate ={（Power consumption before PowerMinistor is applied—Power consumption after PowerMinistor is applied）/ Power consumption before POWERMINISTOR is applied}*100%
Presented in bar chart:
According to the three tested power saving rate, there is:
Average power saving rate=（Power saving rate 1+ Power saving rate 2+ Power saving rate 3） / 3
=（24.5%+23.5%+24%）/ 3
