Graphical data

Figure 14.

Power factor vs line voltage

Power factor improves with more LEDs in the string, but is nearing the maximum. It is quite

sensitive to line voltage, lowest at high line.

Figure 15.

LED current vs line voltage

LED current is quite insensitive to line voltage, trimming may be needed depending on the

number of LEDs in the load.
