What happened to the honer system? That price sounds about right, I believe you can get similar units even cheaper these days.
scholar, I admire your innovation but have you looked into your idea? I have two concerns, heat and less obvious UV. Even with a fan you'll only remove the inductive heat, a fan will not remove the radiant heat which will likely cause big problems with such small volume. Not 100% sure but it's possible you may need a UV shield due to too much UV. It may also just be too intense, I've looked at those types of bulbs before they are brighter than halides and could blind your fish or damage coral.
Also keep in mind HID stands for high intensity discharge and refers to halogens, metal halides, mercury vapor, high pressure sodium and so on.
