orbit marine

I am looking Into getting a orbit marine light and I have a couple questions
1. Are they reliable
2. Anyone have experience with the refurbished ones?
3. Not to concerned about this but will the grow some coral?
4.how nice do they look?
This is going of a predator tank so number 3 isn't really important
And if anyone has a 48 inch one they want to sell let me know! Thanks!!
