It should work fine. I've had hoods with flourescent lights and glass guards that have sustained plant life just fine. However, if you want to replace the fixture with a UV Sun, you need to be careful not to "over-light" the aquarium. Check the wattage of the lights you'll be using in the fixture. There's an old rule-of-thumb you can use that is generally for T8 and T12 fixtures since they are kind of dim, but is usually a good starting point for other lights too. For plant life, usually 1watt per gallon to 2.4 watts per gallon is sufficient. If your tank is 10g, then you want anywhere from one 10watt light to 24w light (each bulb wattage gets added together, i.e. 2 12w bulbs = 24w total) If it is a T5 fixture, you can probably go even less. There are other factors too, like how high the light is from the substrate, the "temperature", and spectrum they give off, but I wouldn't worry about that unless your plants are suffering or you're having algae issues. I've never had a problem with glass guards and getting enough light through to the aquarium. I have a 25g tank that is 18" tall, heavily planted, a glass top, and a dual T5 fixture over that, and never felt like it wasn't getting enough light. In fact, I love glass tops because then evaporation doesn't happen as fast. Just wipe the glass down during water changes to remove any build up, and you'll be good to go.
