For the playfield seems like 44s are low risk in a home environment since usage will be low compared to an arcade.

I still favor 47s or LEDs behind a fragile back glass with any sign of flaking or ink separation. Small trade off for the added insurance against degradation.

Basically everyone is making directional statements. Less heat = less heat cycling/risk of slow degradation of glass from expansion and contraction, warping plastics etc. Less current = less risk of janky old connectors with oxidized pins building up heat and degrading. If there’s lower current draw I supposed the transformer would run cooler, but those seem to be sized with large margins.

Run whatever you feel is best. If there’s an issue do something different.
