Boss? You talking to me?
Err.... no... sorry... as a newbie, I used a similar cheap industrial MH set as my first MH... regretted it immediately as the output is very poor compared to those proper aquarium pendants even though its the same wattage.
(Its still sitting in my cupboard... james72, if you want it, I'll let you have both for $50. )
I then bit the bullet and bought an Aquamedic Aquasunlight 150w x2 DE pendant and it was fabulous for my LPS tank then.
Of course now, I have my own DIY 400w x 4 spiderlight SE light rail system for my SPS.
