You should have about 50 PAR or more, plus good CO2 in order to grow a good HC carpet. A single Finnex Ray2 light should give you about that, if you have about 2-3 inches of substrate. The Fugeray would not be enough light.

Awesome, thanks Hoppy! I was hoping you'd be one to get back to me, your article on PAR values is where I started my research! Thanks a bunch

Refugium is a section of my sump running off the 65. Its roughly 12w x 12d x 8h, with a 17w CFL home depot light clamp light sitting 2" off the water, so roughly 8-9" off the HC (substrate is 1-2" thick, closer to 1").
Here is a full tank pic from a few months ago. I believe the lack of light caused the pogostemon erectus to completely die off (back right), and I'm down to 1-2 stems of ludwigia repens (back left) and 3 stems of ludwigia ovalis (back center). The bacopa monnieri (back left, right of the repens) and rotala rotundifolia (far right, far left) have taken off; my tank looks like a rotundifolia farm at this point.

Here's a pic of the refugium section. The HC in here was planted as individual stems pulled from the top portion roughly 2 weeks ago, so there has been significant growth. Pardon the grime, tank is due for its scrub down tomorrow.

I have a buildmyled xb dutch light on order, just awaiting for it to arrive. I like the ray2, the price was great and its a bright light, but I don't believe its bright enough for a 24"+ deep tank with demanding plants. I was thinking of adding a 2nd ray2 and a monster ray, but personally I'd rather run 1-2 lights than 2-3.
