Well, right now I have a 400w hps with the cheap reflector htg system comes with. Im trying to figure out where exactly the light goes after bouncing off reflector so I can figure out how wide/long the direct light area is. Any ideas?

Try doing straight lines from the edges of the reflector :group:
A 400w with a reflector will effectively light about 1m squared. Obviously the best light will be probably 50cm squared in the middle under the bulb but the difference at the edge will only be a few hundred lumens. If you have good reflective material like mylar or mirrors you can reflect up to 95 percent of the light I think. The aluminium reflector is only about 65 percent reflectivity but does the job.
Sounds about right....I have 4 3gal pots that pretty much are directly under, but also have one on each side of that.
Sure, get a laser pointer, hold it in the place where the bulb is(first remobe bulb) and point at the borders of the reflector. Follow the reflection and draw the area on the ground. You can try to make a photo, set the camera on long exposure time/low ISO and draw your limits!
It sounds kinda complicated, but it's easy.
More simple version:
Without the pointer, just take a short exp photo of the light when working and digitally manipulate the contrast of the photo to get sharper edges.
