New 3x3 tent, but need help with good reflectors!

Just finishing up my current run of 2gal hempys with a 2x4 screen in one of my closets...ive realized the screen is entirely too big since i dont get too good of coverage on the outter edges.

I decided to purchase a 3x3x5tent for this go around for my next run, which will be 2 gal coco smartpots with drippers. Currently i have a 250w hydrofarm sunburnst linked below:

Im looking into sticking with a 250w but upgrading my reflector. I see VerdantGreen uses a diamond reflector and ive been looking for something similar to this or a good reflector that will cover a 2.5x2.5 area.

Im up for any suggestions in regards to reflectors that will cover that size so feel free to post pictures, links, etc!

Thanks in advance

cool tube , sun tube, light pipe, they are all the same...the best option to control heat in a tent..IMO..

my 250 doesnt run very hot with my ventilation which is why im not leaning towards the cooltube route
