Aluminum is one of the softer metals out there, I haven't had much of a problem with tapping it and have yet to break a tap. It's like most procedures, provided you pre drill the pilot hole whith the proper size drill bit, the tap should do its job quite easily. As for permanent wire connection, there are plenty of splice options available should the need arise to rearrange things or replace one of the LEDs. Also not sure why these particular mounts would have to use the screws rather than using a thermal adhesive. You likely have the option of doing that either way, just like the solder type LED mounts.

Somebody order some of these things & let us know how they work!! Maybe I will.... price is reasonable, but I was leaning more towards the 10 or 20 watt LED arrays available these days, with multiple 1watt LEDs arranged in rows on a larger form factor. Not Crees I think, but more than likely sufficient light for many applications. I think I saw a lighting company marketing a couple of 100 watt versions with some kind of lens for megabucks.
