I bought 3 Husky lights for modding...
3Watt, Cree XR-E
1Watt, Cree XR-C
Right now the 3W is running direct drive

off the 18650 and its really bright, in the ~150 Lumen ballpark. Its a 4-wire Cree XR-E, I'm guessing either a P4 or Q2. I can't imagine they are using a higher-premium BIN. Of course its going to

, so I don't intend to leave it this way for long, but it is
really bright for $21

. Stage 2 of the mod will be a DX6190 DC board and a glass lens.
I didn't even bother trying it with 3xAAA cells, its a well made light, good emitter and good reflector.... it deserves better than that.
The 3W is a nice mod host though, cheap and B/M available. It easily comes apart.. no glue anywhere. Good thermal conduction path, and has a 17mm provision for the DC-DC board. The forward clicky is deeply recessed so its hard to press, but it tail stands nicely. The driver pill is aluminum though, so you can't solder it at all. So electrical contact with the DC board needs to be made via physical contact, not solder conduction. The reflector geometry is set up for throw (seems to be a consistent theme with all the Cree Hiusky lights). anyhoot here are some more pics.
