I am not sure how much light glosso needs. Some say in the right environment (high CO2) it doesn't need that much but it seams to me that with less light glosso becommes stringy or elongated and grows slowly.
Your setup sound like a good choice I would opt for some changes though:
1. OD the 2 OD bulbs to at least 3x and perhaps 4x.
2. Get rid of the 10000K bulbs in lieu of cheap GE or Sylvania plant bulbs.
I am only suggesting this because I ODd 3 T12 2x which gave me 3.2 and glosso seems to like it so far; it grows fairly steadily.
