2 Radion G2 vs 3 Vega

[Reef Pilot]

Be careful when comparing the Radions. The Gen 2s are quite a bit stronger (20 -40%) than Gen 1s. I have both, and really noticed a difference.

I have never owned the AI's or other LEDs, so can't say much about them. But have read that the spread for Radions is better (than the AIs) when closer to the water. I have mine 8 inches above, and they seem to work very well at that level.

I have mine in canopies, and I like the Radion cooling. They have fans that exit the air at the top sides, so are good for mounting in a canopy without restricting air movement. My canopies exit air at the top rear, and run quite cool (esp compared to my old T5s).
