Conclusion

A dimmable CFL solution has been discussed and analyzed. CFLs can completely replace

incandescent lamps in dimming systems. With a dimming range of 20%-100%, CFLs are

very energy efficient and have a reliable and longer lifetime. The efficiency is above 80%

which makes this solution suitable in compact applications.
