Neutral white XP-G.  Max amperage is actually 1500mA
Page 3.

The new CREE XML's max out at 3000mA.

Most people run them at less than maximum because the power to light ratio is exponential.  You get diminishing returns on efficiency the closer you get to maximum power.  As long as you can shed the heat I don't believe lifespan is effected.

Current Tunze settings.

Powers heads alternate back and forth every 4 hours, and ramp up from 30% to the upper setting over 3 seconds when it's the active unit, otherwise it idles along at 30%.

Minimum flow is 30% at all times from each.  #1 is on the left, #2 is on the right.  #1 used to have a higher power rating but was blowing sand around.  The left hand side of the tank developed a little algae on the sand bed so I upped the flow going that direction and it's been clearing up without moving sand.  I'm sure I could probably still turn them up some, but I haven't worked at finding perfect positioning and settings for them since I added the 2nd one.

The 6105 pumps would really rock a 6' long tank.  They're kind of big for my tank unless it was maybe full up of mature sps colonies creating drag.
