The bubble tipped require the least amount of light in the list you mention.However,2 strip lights wont be enough for even them.Think about getting some higher intensity flourescents like VHO,T5's,or PC's.A 4 bulb setup would be enough light to keep a bubble-tip and most corals as well.The carpet/ritteri's are reported to do better under MH lighting although there are some that have sucees keeping them under VHO's,T5's
