LM317T Voltage Regulator with Pass Transistor

This video shows the effect of voltage change on efficient electronic ballast fluorescent lighting. Most users of T5 and T8 tubes know that changing their old magnetic ballast fluorescent lighting for electronic ballast lighting saves money on power and replacement costs. However, there is a misconception that these types of efficient lighting cannot benefit from power optimisation. This video shows that this view is incorrect.
