Is it the tube or compact? There has been a problem with the compacts over the last few months with eye damage. It's temporary when it first starts and clears up easily enough, but just keep an eye out for swollen eyes, wanting to keep them closed alot and a lot of blinking. If these signs occur just remove the UVB and go with a fl. tube or merc vapor. The symptoms clear fairly quickly once the compact has been taken away.
As far as the difference in the lights...I'm not sure there is a difference. I would have to see the package to compare the two. It's late though and it will have to wait...;-)
If both lights are 10.0 they are most likely the same bulb with only a difference in packaging. Just likke the ZooMed 5.0 Reptisuns and 5.0 Iguana lights are the same bulb different box. 10.0 UVB is 10.0 UVB regardless of packaging
How big is the tank? A 20 watt is only 24 inches long. As long as it stretches the length of the tank it will work. I personally prefer the Zoo Med lights myself.

the tank is a 40 gallon. its about 33 inches across. Do certain reptiles require a different amount of UVB or is it about making sure it stretches across the entire tank? Cause I wasn't sure if the 10.0 was the right amount.
Out of all the tubes I prefer the ZooMeds, too. They have just proven to be more reliable and longer lasting than the rest.
Yes...some reptiles need more UVB than others, but this is only part of the reason for the longer tubes. The UVB is much weaker on the ends of the tubes while the strongest emissions are in the center. An iguana uses sometimes just parts of the body, sometimes the whole body, for thermoregulation which happens to have UVB, too. They don't know they're soaking up the UVB. They can't detect this. They're just after the heat. The longer the tube - the better that long body can utilize the UVB coming from the source.
