I think you're right here ... I spoke with a inside sales person at sylvania
he claimed the 860 is the highest kelvin bulb they make, at 6700k, that
8xx is their color rendering index (80+).

He claims the 950 has a higher cri of like 91 and is 5500k.  The guy at
osram was supprised to receive my call, as it was the second call he'd
gotten this week regarding these bulbs for a "non typical" lighting

I don't disagree that reflectors are important ... originally I was lighting
my tank with a few t8 strip lights laying on the glass above the water,
talk about inefficent, most of the light was going into the room, rather
than the water.  The new hood I built is painted high-gloss white on the
inside with something called Painters Touch by Rustoleum.  It is a very
bright white, and made a huge difference on the t8's.  I'm sure polished
aluminum could do even better, but imho (for my own needs) this white
paint works really well, and is a lot easier then trying to polish and bend
sheet aluminum myself, and a lot less expensive then a pre-made reflector.

I agree 100% ... AH's prices are so good I've considered buying their
premade retro kits several times.  But a large part of my interest in the
aquari hobby is doing as many things myself as possible (for now I'll leave
the glasswork to the pros at the factory though!).

Thanks for the tip on "hot wiring" the ballasts, I'll have to research that!
