how powerful does a red laser have to be to have the brightness of say a 50mw green? or can it be that bright at all?

As you can see on the chart, red is very low on the scale.

If we consider that red lasers usually have bigger beam diameter, that ratio should be even higher. A particle suspended in air receives more light in a dense beam like green's than in red's.
