Consider T5 HO lights. Some like AquaticLife look great. ECO makes a good looking line. T5 is a very efficient technology. Might not matter to you much if a landlord is paying the bills, but it is more than adequate for planted tanks, offers the flexibility of different ranges of light so you can tune color tone to your tastes. Bulbs last a long time and don't run as hot as MH.
Having said that, MH pendants look great as a hanging fixture and the ADA fixtures are lookers. You can;t go wrong with them, but have fun shopping.
