Looking for Good Metal Halide Reflectors

[GreenSpottedPuffer]

Ok so I found both the Lumenarcs and comparable Lumenbright reflectors I like but they will not work with my canopy. Not only do they just barely fit in but they would be just a few inches off the water surface. They are suppose to be like 12-16" off

So looks like I am stuck with U shaped reflectors for now. Or something low profile. Any ideas?

Anyone selling this type of reflectors? At this point, anything is better than what i am using now. They are really old and dull.

Thanks!
