Good question.  I am not sure where these pressure difference recommendations came from, but let me give you a little background.  The key physical constraint to good operation of a press

I do not know of any way fluorescent lights would directly affect banana ripening.  This is especially the case because the fruit is in boxes and the boxes are palletized so only a tiny amount

Immature-green bananas may fail to respond to ethylene and ripen even after exposure to 100 ppm ethylene for 7 days.

Mature-green bananas respond to ethylene (ripen as indicated by color changes from green to yellow, pulp softening, skin thinning and ease of peeling, higher respiration and ethylene production rat

Banana skin splitting can result from high relative humidity (>90%) plus high temperature (>70 F), especially in bananas that are harvested fully mature-green (round in cross section). 

Exposure of bananas to temperatures above 30 C before and/or during ripening can inhibit ripening of the peel more than the flesh (edible portion).

I am not aware of visible light having the effect of reducing mold growth, at least the decay that affects bananas.

Although ethephon is approved for preharvest application on processing tomatoes and table grapes with a maximum residue limit of 2 ppm, it is not approved for postharvest application (
