I use the regular non-lightcycle version of that fixture, and its great. The light cycle feature is mainly a gimmick, and not worth the extra cost over the standard version. Make sure to buy the version that most closely matches the wattage of your bulb. IIRC, these fixtures come in 20w, 30w, and 40w varieties and work with either T-8 or T-12 bulbs. You need to have both bulb locations filled however, as it won't work with only one bulb installed. So use one UV tube, and another standard non-uv tube for extra brightness.
