how long has tehse new lights been working? The anemone might take some time to adjust to the new lights. Even when changing bulbs on halides, corals etc can go into shock so just give it a few days to see if it slowly comes around.
Another possibility is that you have changed the K ? Were your lights higer K than the new ones? sun light is closer to 7.5k and you are now moving a long way off of sunlight.. 14k with actinics which are closer to 22k so you could average them out to about 18k. This is a very cold light and a long way from natural sunlight (which is what anomeones love) Lovely for showing off colours though. Again, i would give it time and see if it can adjust. It will probably move higher up to get closer to the lights if it feels the lights are not strong enough.
