Though given, it is irrelevent ! Lumens are for Humans not plants ! Lumens measure how we see light. Our eyes prefer green light. Green light has the most Lumens, Red and Blue the least. Most fluorescent lamps are made to look bright for humans by adding huge spikes of greeny yellow light.
Lumens only measure how BRIGHT the light appears to us.
Lumens cannot measure light useful to plants

Par is for plants, lumens are for people.

Although lumens are in many ways a minute measure of intensity of light for plants, as generally the greater the lux of a particular light the chances are greater that the intensity of a particular spectrum is.
