The dimmer I’m using – Leviton 6633-P, is on your compatibility list.  When I installed the lites, they only dim to about 50%.  Is that normal?  With halogens I can reduce it to almost much 0% light.

Hello,

Concerning your issue, this might help.

There are 2 different types of technology as far as dimmers go.
 

  • Forward Phase – Most Common Dimming Method (150 million dimmers in use) – Not originally intended for use with LEDs, performance issues possible  

 

  • Reverse Phase – Typically used for ELV loads, typically perform better with LEDs – Smaller install base, usually require a neutral wire

 
 
Lamps generally use only forward/reverse phase control – Fixtures can use any method – The LED and control MUST use the same control type.
Dimming range varies greatly – Some dimmers may dim only to 50%, others to 1% Incandescent lamps dim to below 1% – (orange filament glow)
 
I understand that the dimmer you are using is on our compatibility list. However not every dimmer is compatible with every bulb. We usually recommend using 
LUTRON CL DIMMERS, as there are usually no issues with that dimmer. If possible, you may try to get the dimmer exchanged for another one at the place of purchase and see if the problem persists.
