Mystery Luxeon part LXHL-NX01?

I just looked at Future-Active's site and found two Luxeon parts that were in stock but unfamiliar to me: the LXHL-NX05 for $5.00 each (I think this is the collimator, right)?, and the LXHL-NX01 for $45.00 each.

Anyone know what the LXHL-NX01 is? Is this one of the new 5W units?

The only NX01 I know of is the registry number for the first "Enterprise" starship. Maybe it's an inside joke.

Let's see if I can come up with anything.

Nothing on the Luxeon website about them. May be a run of some custom part that was made and then refused by the original buyer.

Checking the future electronics site, they have NX01, NX02 and NX05 as well. Along with about a hundred other Luxeon parts.
Unfortunately, they have no photos or specs online, so it's anyone's guess as to what these are.
