probably not
you want a couple of 36watt globes for most plants in that size tank. It also depends on what plants you are keeping and how long the light is on for. Have the light on for about 12-14hours per day. if you get lots of algae then decrease the photoperiod. If you don't get any algae you can increase the lighting time to 16 hours per day but they must have 8 hours rest (darkness).
As for the plants, try to buy plants that cannot support their own weight when they are removed from the water. If the plants stay standing up after they have been taken out of water they are probably marsh plants and won't do that well in an aquarium. Hygrophillas, Swordplants & Cryptocoryns are exceptions and do well under or above water.
Some good plants to try include Ambulia, Hygrophilla polysperma, Ludwigia, Elodia, Swordplants & Narrow Vallis.
