Light intensity must vary according to the specified curves
Two Curves – White and Colored
Light output must change with input current
Light output must be based on continuous curve
No discrete step intensity changes
Detailed relative brightness requirements found in Tables 3 and 4
Current is measured at primary and secondary
Primary current is value used for compliance
Testing must be done with both SCR and sine wave CCRs
Testing must be done with full and half loaded CCRs
