Since you were gone only 9 months you should know all about the Cree revolution.
The only 'new' LED since then is the SSC-P7. It is just 4*Cree dies in a huge LED case. The lights so far out are the cheapies from DX and KD or M@gmods. Wolf-eyes just released theirs and Battery Junction started taking pre-orders for the Lumapower. Surefire announced the UB2 Invictus.
Some manufacturers have released LED lights with the 5A neutral warm white tint. Dereelight is the 1st followed by DX with a
P60 drop-in. Fenix just announced theirs.
McGizmo released the Sundrop with a high CRI LED with even better colour rendition.
