In this paper I reviewed the effects that Compact Fluorescent Lamps (CFL), Light Emitting Diodes (LED), and halogen lighting have on power quality. The CFLs and some LEDs present a much greater non-linear load on the distribution system compared to incandescent lights, a common light source used in the past. The reason for the phasing out of the incandescent light was due to its poor efficiency compared to newer technology. A congressional bill was passed at the end of 2007 called the Federal Independence and Security Act which bans the manufacturing of the standard incandescent light bulb. As the less energy efficient incandescent bulbs are phased out, the new low energy lighting is being phased in, sometimes at the cost of power quality. As far as power quality is concerned, some low energy light choices are better than others.
