I have two reefbreeders Photon 32 V+ over my 215 gal SPS dominated system. I also have it supplemented by 4 Orphek 60" light bars. 2 in front and 2 in back with the photons in the center. I like these lights...6 independent programmable channels with ramping up/down of intensity. Easy to program, great customer service. Are they Radion G5's or Orphek Atlantic V4's no .....but the 2 cost me less than $1K, (now a little higher). I do feel they need supplementation that's why I added the Orphek light bars, (2 Blue Plus and 2 Day Plus). I previously had supplemented them with 4 ATI 80 watt T5's, (2 blue plus and 2 coral plus bulbs). I believe I would need four Orphek Atlantic V4's over my system or five Radion G5 XR30 Pros to improve upon my current lighting ($3.6 to $4.5K vs $2.2K...what I spent on 2 reefbreeders and 4 OR3 light bars).
