Different in the fact, that it is causing the strobbing. If using Halogen or CFL lamps, you have the wrong dimmer switch.
Dimming lights with built-in transformers
Fully loaded halogen transformers usually dim quite well. If you are planning to dim halogen light transformers, try only dim traditional transformes, because toroidal core transformer do not usully dim well. Most of the cheap halogen light transformers belong to this category as well as the transformer in for example PAR36 pinspot lights. When dimming transformers it is a good idea to put a fuse in sereis with the transformer primary so that it will blow when transfromer tries to get too much power from the line. This will protect the transformer from overhating which might be caused because of transformer core saturation (which might be caused by small DC bias caused by not very well operating dimmer). A proper fuse will save transformers from burning out.
If your halogen light system uses an electronic transformer then you must very carefully check if it can be dimmed. Some of the electronic transformers are made dimmable and work well with traditional light dimmers. The ones which are not ment to be dimmed can be damaged by the dimming."
