Only problem with that link is the bulbs are totally wrong for a planted tank. I would go to Aqua Botanic and get the light, pay a little more but get the right bulbs. Robert is the only place in the US selling the JBJ lights with plant bulbs.
Now to answer the question. You have been doing fine with low light plants and you want to move up. Going from 1 wpg to 4 wpg is a huge leap. You need to study up on fertilization, you will need a CO2 system, pressurized is best. You really need to think about it. If I were you I would head on over to AH Supply and get a 2x55 watt kit and retrofit it into your strip light. This will give you a 2 wpg tank. And you will be able to grow a lot more plants. Once you have mastered this level then you can think about moving up. I have a 55 gallon tank with 220 watts over it and you need to stay right on top of it or it will explode on you. Depending on what you call high light you will need from 3 wpg gallon and up.
