No doubt that you have heard of the current gen LEDs, the two big companies are Cree and Seoul. The current gen LEDs are twice or more efficient then the last gen LEDs, which means for the same power, a current gen LED will have twice or more output then a previous gen LED. The Cree XR-E R2, current highest bin for Cree, hits over 200 lumen and can reach 300 with a bit over over driving. The quad die LEDs like the MC-E and P7 are similar to the Luxeon V in the sense that they pack 4 of the normal LED's dies into a single package. In the Seoul P7, the dies are wired in parallel. In the MC-E, each die can be individually addressable.
What do you want for a new light?
We have over 60 lumen from a single AA powered light (best I've seen is 140 lumen), over 120 lumen for a single CR123 light (or over 250 if an IMR RCR123 is used to direct drive a quad die LED), over 400 lumen for a single 18650 battery powered light.
For example, the Fenix P2D hits 110 lumen out the front, with the Q5 bin, that is over 140 lumen (similar number to the current replacement for the P2D, the PD20).
There have also been improvements in throw. The Dereelight DBS hits over 20,000 lux at 1 meter. The Tiablo A10 has a calculated 40,000 + lux at 1 m (calculated from 5m). The aspherical lens mods get over 50,000 lux at 1m. All of these are with single die LEDs.
Luxeon has their Rebel and TFFC K2s, both are current gen LEDs.
