That's a tough call, and if I were you, I'd base the decision on what you plan to keep in the tank.
The advantage of the Jebo is that you have much higher light output. This is critical if you plan to keep any corals or anemones, as these animals have a photosynthetic algae within their cells, and if these don't get enough light, thety can produce the food they need for themselves and the host organisms to live. On the other hand, if you only intend to keep fish, or non-photosynthetic inverts (snails, shrimp, crabs, hermits), the petco light is fine. In the compact fluorescent, if you plan to keep corals and anemones, you'll need to replace the tubes about every 12 months or sooner, since the wavelengths needed for photosynthesis are reduced over time, and won't be able to keep the animals alive, even though the light itself hasn't "burnt out" - that's something you also should consider is the price/frequency of the tube replacements.
I've seen these used with glass covers, and this has both advantages and disadvantages. The disadvantage is that it's another layer for the light to go through, and each time light passes through glass or plastic, some of the intensity and wavelengths can be lost. There's also a tendency to trap heat, which can be harmful to corals and anemones (any of the photosynthesizers) because if the temperature rises too high (over 85o for an extended period), the organisms tend to expel the photosynthetic algae, leaving them without their food source (although some can also take food particles from the water, but this will mean having to target feed, and mose wastes in your tank). The plus side of using the covers is that it reduces evaporation, so you don't have to top off the tank as often, plus it keeps your fish from jumping out of the tank.
If you use the glass cover, you could always remove the plastic from the Jebo hood and just use the cover itself as the way to protect you lighting system from being splashed by the saltwater.
Really, this is a decision you'll need to make yourself, based on the above info, your budget, and the types of organisms you want to have.
ADDITION: Since you only are looking for these as a system for a tropical tank, you might want to go with the twin tube fluorescent. If you look at the two systems in terms of watts per gallon, the twin fluorescent will give you a little over 2 watts per gallon, but the compact will give you over 3. The 2 watts per gallon will be fine for the low light plant's you're looking at buying, and you'll have less problems with algae growth. Also, the more light you have, the closer you get to having a CO2 system as a necessity. The other info regarding the cover still applies.

If you are looking for a light strip (single or double) you can find them at home depot or menards in the lighting section.

can not extremely restore or replace it, as quickly as that form of LED stops working that's finished. you will basically could desire to get a stand on my own LED unit. you may regularly locate them for $10-20
