Why you can't ship the A21 bulbs to California?

I'm trying to order a CENTRIC HOME™ Flicker-Free A21 15W LED Bulb to test out but your website says these cannot ship to California. What is the specific reason for this and are there any ways around this? 

While our A19 bulbs have been recently updated to align with California-specific voltage standards (California Energy Commission Title 20), our new A21 bulbs have not yet received the same update. 

The specific issue which makes those bulbs non-compliant is the power factor requirement of 0.7 according to the CEC Title 20 ordinance. Unfortunately, these bulbs have a power factor of 0.6.
