Maybe we ought to start a poll on the pull out?

Here's my choices:

-Price. Too costly for the casual cyclist or those who rarely ride at night
-Weight/form factor
-Lack of a strobe- We 'mericans tend to like our gear as multifunctional as possible
-Run time
-Batteries are older tech.

The biggest reason is probably the lumen to dollar ratio. A bunch of people don't take the optics into account (or plain don't care) and it's hard to justify spending $200 on a 450 lumen light when a more powerful bike specific light can be had cheaper (Cygolight, NR, others) and then the MagicShines and their clones offer more power, longer run time, not to mention the plethora of cheap tactical flashlights that offer more power for a fraction of the cost.
