Hi, Sylvia,

Yes, they look similar, but they might be not _exactly_ the same thing. In
optics, even very small differences count. It's hard to say anything
without actually measuring the ligth output. One thing is for sure: a
parabolic reflector works at its best when the ligth source is pointlike.
The more you move away from a pointlike geometry, the harder it gets to
design a proper reflector. This is why I'm thinking even of using T5 bulbs
instead of T8 to build a ligth canopy.

Hope to get some results soon...

Be aware that the Triton reflector is 6.5" wide, so it won't fit in the 
opening of your canopy. The AHS reflector is better in this regard, it
is 4" wide.
