Had two of those on my handlebar for years. Time to get something stronger.

i am basically looking for similar setup, just stronger.

On my old L2D i liked :

1) self contain system.
2) easy to transfer them from my MTB to my road.
3) can use it as a general purpose flash light.
4) Can use regular AA or AAA.
5) high quality and Bright !

Any suggestions ?

thanks
