![]() heres a realistic comparison
Radion: 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 White and blues on radions equal to 94 Watts 4x Cree XP-E Green LEDs run at 3w each 4x Osram Oslon SSL Hyper Red LEDs run at 3w each i dont consider these as photosynthetic light Sols: 8x 3 watt white 8x 3 watt blue 8x 3 watt royal blue total 72 watts so with radions you're basically paying more than double for an additional 22 watts. and when you consider that the radions dont have any kind of optics; that 22 watts probably just gets dispersed into the water or ends up lighting the inside glass of your tank |

![]() I was asking more about the effects on intensity when switching out the 40 for 70 degree optics.
