The bracket is MUCH nicer than I expected. I'm seriously considering upgrading my tank to a 45P... if I can find one. Until then, I'm looking to suspend it without the bracket.
It also would fit the Mini L (same as 45p, just not as wide) and 45-F (similar tank shape to the one you have).
How about fishing line to hang the light? That would be pretty easy, you said you were going to drill the stand? Or you could get a custom piece of acrylic cut that fits the light and drill two holes and have it suspended with clear fishing line.
