Syno, I tend to agree with you. I think that often times anemones do not have to be kept under extremely high intensity/wattage systems. I do believe that some species require higher intensity than others (H. magnifica vs. E. quadricolor, to illustrate the point), but even in the case of the most demanding species, such as H. magnifica, PC's are just fine as long as then anemone is close to the bulbs and the Kelvin is in the correct range. Though an animal may be capable of adapting to a tank with a 400 watt MH (or whatever) doesn't mean that it is the best choice in terms of energy consumption, heat issues, or even health of the animal. The argument invariably is, "even the brightest lights we have available do not produce any where near the lumens of the sun on a reef." That may be the case, but aquariums are very different ecosystems compared to reefs. Also, some host anemones come from depths and conditions where light can be pretty scarce at times. In aquariums we are providing 10-12 hours of illumination, most likely 365 days a year barring blackouts and ice storms.
