Characteristic
Requirements
Transient protection
requirements: all luminaires
Ballast or driver shall comply with ANSI/Ieee C62.41.1-2002 and ANSI/Ieee C62.41.2-2002, Class A operation.
The line transient shall consist of seven strikes of a 100 kHz ring wave, 2.5 kv level, for both common mode and
differential mode.
operating frequency
requirements: directional and
non-directional luminaires
Frequency ≥ 120 Hz
Note: This performance characteristic addresses problems with visible flicker due to low frequency operation and
applies to steady-state as well as dimmed operation. Dimming operation shall meet the requirement at all light
output levels.
Noise requirements: directional
and non-directional luminaires
All ballasts & drivers used within the luminaire shall have a Class A sound rating.
Ballasts and drivers are recommended to be installed in the luminaire in such a way that in operation, the
luminaire will not emit sound exceeding a measured level of 24 BA.

2. DEfinE DEsign goALs
In addition to the requirements given in the above tables, we examined existing 39-w CmH lamp data sheets to develop
the goals shown in Table 6. we found that the input power for luminaires using 39-w CmH lamps is 44 to 45 w, so we
targeted this reference design to be at least equivalent.
Table 6 shows the design goals for this project.
