LED lights have bulbs that last for years. They are more solid state, and so more immune to water corroding or shorting them. As you know some even work underwater.
The strips on top are better, providing more natural light which you'd need if you grew live plants. Even with plastic plants it will look more real. The sunken lights, if the room is dark, can confuse the fish and they line up sideways as if the light was UP. LED light is coherent, and spreads less than conventional bulbs. That gives it sparkle like real sunlight, and by not spreading, goes straight in the tank instead of bouncing off the inside of the glass and encouraging algae to grow. The sunken lights aim their light straight toward the glass so give up one advantage they had over old style lights. There are clips on the ends of the strips that act like legs to hold the fixture above the glass top. That is the way I have mine. There is another style that clips on the back of the tank frame and has a goose neck, like a desk lamp, so that the light can be aimed and adjusted over the tank. There are LED's that can be placed inside existing light fixtures (retrofits) changing them into LED lights.
The last link below has the strip light I would suggest for your tank with artificial plants. The legs pull in and out of the strips so you can adjust them exactly to your aquarium. I like the double bright with twice as many LED's and getting the biggest length strip that will fit my tanks but I have lots of live plants in most of my aquariums.
