Strings Dilemma

For some reason I couldn't continue on the original post although nothing was found such as reaching the character limit in the box...
Hence I continue:

The strings I purchased is D'Adario EJ16-3d that literally suck in everything: action and kind-of unfocused i.e. not sharp sound so I can hear a different tone coming from the string other than it's suppose to be. In strumming action I guess It's OK, but otherwise as a learner I'd like to hear everything crystal clean and virgin untouched.

I'm pretty sure that there are loads of 'goners here that had played tons of different strings and on different guitars that could discuss this above post with me. For your quick reference my Tak mentioned above is solid top electro-acoustic guitar that sounds great both ways.

this 'brand' of strings is all over the stores with all different model numbers that are really hard to trace... previously buying a set of new strings for low $3 range would suffice until i hit this bummer.
i've never asked recommendation although have a few brands written down they were mostly for medium action strings that more for rock'n'roll and folk rock hard strumming now i need ones that sound nice and light for most of the time finger picking.

action has two meanings one of them is the distance between fretboard and string which is almost lowest to the point i could strum without having strings bounced to the unwanted frets.
another meaning makes me believe that strings themselves have also meaning of action in addition to gauges.

another reason i figured that 12 really isn't a light action which solves the most of my equation.
for blooz or jazz i need to find lighter.

ok tension
i was confused with gauge 12 marked as light...
