There are xr15, xr30, xr15 pro or xr30 pro. Cross that with all five generations and you have up to 20 lights that you could have. Throw in diffusers and then there are even more combination. I think that people definitely need to explain what Radion that they have.
Let me be even more rude... since I appear to be already... if you cannot pay attention to every detail, no matter how little, then you will not be very successful in this hobby. Think about what you are looking for and give enough background to help the reader help you... but not too much all at once that people tune out.
Lastly, whist I am still being rude... gather your thoughts on what you really want to keep since "keeping SPS" is not good enough for good advice. There are people who keep mixed SPS with lots of montis, birdsnests and plating stuff... and then there are people who only keep acropora.... and then those who want to keep ALL acropora and not just the easy ones - there is a wide range care requirements here. The BEST people who will be able to help you will chime in when they know what you are looking and you will get more specific help than people who respond in generics.
Now... you could see all of this as rude... or the best advice that you have gotten on this thread since you are going to need a lot of help going forward. It is up to you...
