JA8 certified light source
You're not allowed to use fixtures where some fool could remove the LEDs and install incandescents.  Hence if you use swappable "bulbs", the lamp socket must be a unique type made exclusively for efficient lighting. This is done for two reasons: 


efficiency, as it defeats the purpose of efficient mandates/incentives if some flat-earther can just screw in inefficient bulbs.  
safety, as these odd-socket or no- socket fixtures may not be rated for the 60-100W heat of an incandescent.  (Or to be more precise, efficiency rules enable lamp designs that don't need to dispose of incandescent heat, freeing designers to innovate).
