How would you categorize flashlight features?

[Raven]

I would have three categories for size:

Key Chain Size: can reasonably fit in the pocket without too much bulge

Belt Size Concealed: a tad bigger than a pocket light - could probably fit in your pocket but would look/feel weird - can be hidden from view if carried inside a pouch

Belt Size Open: a full sized light that will feel out of place on your person unless inside a pack, hooked on your belt, or carried in your hand - impossible to conceal

Then there are other features that each light has besides size:

low power consumption
high power consumption

rechargable
battery
solar

wide beam
narrow beam

impact
non impact

water resistant
water proof

Did I miss anything?
