There are a bunch of LED lights you can get - I know the Razor is a really good unit. I run the Radion Pro's (Super expensive though). You have a 48" tank so I don't know if you will be able to get away with a single Razor. Don't worry about what LED strip you got - the Blue one you got is super useful to your coral, and even if you upgrade, you can keep it on the tank knowing it is helping.
If you are looking to do it on the cheap, you can always get 2 used AI Sols for around $250 each and they will nicely cover your tank. However - if you want something REALLY special, check out the new AI Hydras. They are BRAND new, only $399 each (compared to my 1 light for $899), and are FULL spectrum - including the UV and Violet! Not to mention they are fully controllable and you won't need to manually dim them - you can set the EXACT color you want. Definitely worth a look.
Edited: I love the way the Razor's look, I absolutely LOVE my Radion Pro's (and the G1s and G2s) - but I don't want to push either of them on you because they are very expensive and unless you want to, you probably don't need to spend a small fortune on your lights (I keep mainly SPS, so I wanted the Radions). After looking at the new AI Hydras, I really think they are something really special. For $399, you aren't going to beat them - especially in the full-spectrum department. None of the traditional LED fixtures (including the Razor) have ANY sub-460nm lighting. Take a look at the Photosynthesis chart I put in my above post and note where a good deal of that main peak is - it is below 460nm. The Hydras have both 420nm violet lights and 405nm UV lights to give you that boost. Plus, UV/Violet looks absolutely AMAZING for color pop - it is basically a black light for your tank. My Radion Pros have UV/Violet and every night I have a twilight effect with Royal Blue, Violet, and UV JUST for the way it looks. You will be happy with any of the fixtures though :)
