You don't really need an aluminum plate to mount the sunblasters onto, you can mount them onto anything really. I had mine mounted in my wooden canopy. Ofcourse if you want to add reflectors they can definitely help. You also can get away using 4 fixtures, 10 is overkill on a 4og. Another cost effective solution is painting the inside of your canopy white as this reflects the light even more!
