Here advice concerning light is based on readings with a PAR meter, which measures the available amount of light that can be used for photosynthesis. The watt per liter rule is outdated and obsolete. To give you a good advice, we need the size of the tank.
You could use 3 tubes of 54 Watts with good reflectors, if you give them a good spread of 15 centimeters. If you don't want to use reflectors, but a white painted hood, use 4 x 54 Watts. This will give you enough light to grow every plant you want. More light will make it harder to meet CO2 demand and there's a bigger chance of getting algae because of that.
You can use every bulb you want that makes the light of the tank appealing to you. Your plants will grow anyway. You will never notice the difference if your plants grow 1 cm. more or less per month because of spectrum. All daylight type bulbs have enough red and blue to allow photosynthesis.
