Looking for feedback on this setup:

I am working on setting up a small & effecent flowering room. My main goal is to have 1-2 Medium or 3-4 Small Plant Flowering withing this room. I do Low Stress Training with my plants so I do not need a ton of space because I can easily control the size by additional training. Here is the plan...

Box Size: 5 Foot Tall x 4 Foot Long x 2 Foot Deep
Finish: Inside will be painted with flat white
Light: 400 Watt HPS & 320 Watt (Combined) Flour.
Grow Square Footage = 7.5 Square Foot.

53 HPS Watts/SQ FT + 43 Flour Watts/SQ FT = 96 Watts/SQ FT Total
7100 HPS Lumans/SQ FT + 3200 Flour Lumans/SQ FT = 10,300 Lumans Total

I will use 2 10" Fans to move heat & air outside with 2 - 4 Inch Air Ducts.

My Questions:

1. Is this way overkill for light in this space?
2. Are the Flour really doing me any good or should I use just the HPS?
3. Will I have too much heat build-up in this small space?

Any Feedback would be greatly appricated.

Thanks
