• 8x Cree XP-G Cool White LEDs run at 5W each
• 8x Cree XP-E Blue LEDs run at 3W each
• 10x Cree XP-E Royal Blue LEDs run at 3W each
• 4x Cree XP-E Green LEDs run at 3W each
• 4x Osram Oslon SSL Hyper Red LEDs run at 3W each

when added up, radions are only 118 watts. and when you subtract the 12 watts of red and 12 watts of green (which are not proven yet to make any kind of difference to coral growth) you're only at 94 watts of proven coral growing power.

even if red and green are beneficial to corals, the penetration and usable light at a reasonable depth would be almost nothing

No way was 2 AI's enough for my 120g for my liking from what I saw. IMO 3 or 4 AI's for sure would of been enough. 2 Radions look awesome!
