I made a phone call to Lutron technical assistance(800-523-9466) and they said...

I must use a "magnetic" type dimmer for dimming incandescent lighting with magnetic transformers.

I must use a "electronic" type dimmer for dimming incandescent lighting with solid state electronic transformers.

So since I wired both types of lighting to the same switch...there isn't a dimmer for this purpose.I'll have to cut in another switch to seperate the 2 loads.
