Convoy T4

Convoy t4, a four pack of eneloops and a charger.

T4 is definitely worth trying and has a lot of emitter options. The driver output was recently increased to 6A with lithium ion, so it can drive emitters like the SFT40 and W2 pretty well.

My recommendation for a light that meets both those criteria is the Convoy T4. Can take 2x AA lithium primary batteries for more output and longer runtimes and has a mechanical tail-switch.

This shape is why I like the Convoy T4 so much.

Convoy T4 with nimh has been a popular recommendation for the car because it can take the extreme temperature ranges

The T4 will be better than the others as it is 2AA, but they all can be optioned with a lithium battery that I highly recommend alongside an inexpensive charger (sold on the same site)

If it's going to be AAs and not 14500s, I'd say Convoy T4. 2x AAs doubles the capacity and it's a bit brighter than the single cell lights.

Maybe a convoy T4?

Convoy T4 > Convoy T6 I'd say.

T4 uses two AA or two 14500 (stacked) for longer runtime. $19.79
