Hello,

I have just installed a HS 220 Dimmer Switch to operate dimmable LED direct wired T8 4’ tube fixtures (no ballasts).  Each tube is rated at 16Watts with 2 tubes per fixture.  The switch works and dims just fine with only 2 tubes plugged in (1 in each fixture, or 2 in one fixture)  if I put 2 in each fixture, or 4 total, then the dimming does not work,  the lights all flash at anything less than full on.  The switch is advertised to handle up to 150W.  4 tubes is only 64W.  Any ideas on how to resolve this? 

The switch is a HS220  Hardware V 2.0  Firmware Version 1.0.3

 

Thanks
