Is a 250W MH 10x stronger than a 24 W CF? My question actually pertains to the depth of the tank. If I have inverts 4 inches below the lights with a 24W CF, can I put the same livestock 40 inches below the 250W MH and get the same light absorbtion rates for the corals. Is there some sort of chart showing the loss of light vs. depth.
