Alikat, as long as your anemones are within say 12 or 15 inches of PC lighting and the spectrum is appropriate (daylight 6700K or 10,000K) BTAs do great. If you don't like the white or yellow-white light, you can have a blue bulb too, but make sure you have the daylight. You will want to make sure your bulbs aren't old (change them by 7 or 8 months), the acrylic shield is removed (unless you have fish that will spash the bulbs), and the fixture is as close to the water's surface as possible. PC light is intense, but it doesn't penetrate all that well compared to T5 (with individual reflectors) or MH.
