I'm using the Littelfuse Q4008LH4 (alternistor triac) and the Q2008L4 (standard triac) for digital dimming control of a standard incandescent bulb. Both should operate the same way for this application.

I'm having troubles making the Triacs behave as they should. When they have no load the AC sine wave is clipped as it should, however once I turn on the lamp it stops behaving as it should, and just seems like its full on. Any idea whats causing this behavior? I feel like Ive done the exact same circuit before and didn't have any issues, but this time around I am.
