If you are asking whether a 30mw green laser is as powerful as a 30mw red laser the answer is yes. You can of think of it as a ton of feathers and a ton of bricks, although different they both weigh a ton.
The thing is that green is much more visible to the human eye than red is, so if you were comparing a red laser and green laser, the green would seem much more visible. Although the green looks more "powerful" they have equal power.
