If the extra cost isn’t going to damper your wallet too much I would get the pros because it’s cheaper to that then it is to buy the standard light and realize that you need pros. Then have to buy a second set of lights.
The pros have more LED’s, so better coverage at deeper parts of the tank even though they have the spread. Your tank isn’t super deep so you could probably get by with standard G4’s, it’s up to personal preference and your budget lol.
