Shotgun light - Flashlight mount or weapon light?

[Quick_Draw_McGraw]

So what are people's opinion on lights for a home defense shotgun.

I've been working on getting a second home defense shotgun setup going, and I'm wondering which direction I should go with a light.

Option 1: Flashlight

I'll replicate what I already did which was get a flashlight mount and do a barrel attachment for a Fenix TK11 light.

Option 2: Weapon light

I'll buy a dedicate weapon light, most likely a Streamlight TLR-1.

Anyone have any pros or cons to consider? My budget is to stay under $150 in total investment, and that includes all the mounting hardware.

Streamlight with an elzetta mount. End cap button is easily pushed.
