Sorry I don't know a thing about LOR. I was assuming you would be using an LE.
An LE can handle 2A per channel. A 75W halo spot will be .625A so you could run 3 on a single channel of LE. Better yet, run discrete: better for for the show AND spread out your requirement.
Now, for giggles, lets assume you want to run 8 spots: 8 LED bulbs at $50 per is $400. 8 Old school halogens cost $50. 8 - 75W halos are 5A. 8 - 18W LED is 1.2A. If you can't run incan spots from LOR, save yourself $250, get an LE ($100), 8 incan spots ($50), and gain another 8 channels for your show. Actually, you could get 2 LE's from the money your saving going incan.
Although I don't own an aether I (missed coop), it is documented the aether II is brighter. If I recall the pattern is relatively the same as both use the same fixture. Lenses can change all of that. I wanted the widest spread I could get so I run mine with no lenses.
I didn't really like 12V business going into building the aether II, but found it was not a big deal at all. Also keep in mind the aether II cost quite a bit less than I. I think something like $30-40 different.
Personally, when you realize you need to mount the tranny vertically 18" from ground, it kinda ruins the small tranny idea to me. Plus most guys will run multiple floods...
