Fragmented,
I was in the same exact boat as you are right now.
I looked at Radions, Kessils, Reefbreeder, Oceanrevive.
There are more, but these were the popular ones.
Radions: wow, talk about impressive lights! Too expensive, but if I had the money to burn, I would definitely buy them. I need two.
Kessils: also a really nice option, but I worried that I would get that spotlight look they seem to give. I figured if I was going to pay $800 for Kessils, why not just buy Radions. Again I need two.
ReefBreeder: a good light with some control options. It turned out that they upgraded their 48" unit, but did not have any in stock. I was told I could have a refurbished version 1 unit for the same price. When I asked them why? They back peddled and said $50 off. Why would I want an old unit (refurbished) for only $50 off? I decided to pass.
Oceanrevive: really the Toyota Corolla of the pack. While they lack a lot of the bells and whistles of the rest, the price can't be beat.
The bottom line is for $148 a piece, they give a ton of light and turn on and off.
You can also program the intensity of two channels.
I chose the Oceanrevive for this reason. It'll get the job done for now. When I am ready I would definitely buy the Radions.
With this setup, I can buy my Radions one at a time so it doesn't hurt so much. $750 a pop, I'm sure I can get them cheaper.
I hope this helped!
