why can't you use a regular dimmer sometimes?
Dimming Magnetic Transformers
Why Use Lutron Magnetic Low-Voltage
Dimmers?
Magnetic transformers are inductive loads and are
sensitive to DC voltages. A magnetic transformer
subjected to DC voltage can overheat.
Do not use regular incandescent dimmers for
magnetic low-voltage lighting. Regular incandescent
dimmers often contain a small amount of DC voltage,
which is harmless to a regular incandescent load but
may damage magnetic transformers. Lutron MLV
dimmers are specifically designed to prevent DC
voltage from being applied to the transformer.
