I was looking to buy some reflectors but it was brought to my attention that I could use Mylar or Solar material from Lowes.

Could I just attach the Mylar or solar tube material to my canopy or does it have to be more rounded around the bulb?

I was thinking of just glueing it to my canopy like wallpaper. Also, any possibilities of fire hazards that you might know of???

I have a 120gal reef with 48" VHOs (440 watts) mounted to the canopy towards the back and a 48" Coralife PC (260 watts) sitting with legs inside the canopy towards the front. The Reflective idea is for the VHO's. My canopy is wood...with a "lift up" top and open back.

Thanks for the feedback.
