If you do a search on the forum there is a link to various fixtures Par levels which would tell you where you light level is. I've used Corallife T5HO fixtures and they did the job but I'd heard some say the reflectors aren't as good as many others are. I think good bulbs also matter which is why I use Geisemann bulbs in all my T5HO fixtures that they fit. I still think you'd be somewhere in the medium light range.
