If you have a 48" long 55 gallon tank, I would probably go with this one :

or

I have used Big Als before and have had no problems with them. Their prices are competitive also. I have never used webaquatics so others can vouch for them.
These are good lights, run cool and don't use a lot of power. They should do just fine for the plants you want to grow. I have 5 of these lights on various tanks in my fish room and have not had one failure.
