I'm in no way an expert but if the total output is 36W then not useful for reefs. You should be looking for 2W - 3W LED diodes. 36w/72 lights gives you 0.5w and since they generally run at 80-90% to avoid heat you end up with 28W total.
It will however work for supplementary lights say coupled with t5,
Again not an expert, just in the process of shopping for led's myself and basing my answer on what I've found in the process.
