The new XP-L LED of Cree. All are avaialable as bare LED, LED on a 16mm round base, LED on a 20mm starbase. All bases are aluminum. Prices are the same, only the coolest cost less (I think it's a price error - why should it cost 20% less).
Bare LED $5,66, LED on a base $5,77 coolest white base LED $4,34, on a base $4,45. Here is a thread which compare the XP-L with the XM-L2 (include dedomed) and a thread with information around the XP-L.
