Why you don't read a little of my thread, "Light for law enforcement"?
Just to get an idea of what it is available and how they perform for you.

Less than $50 is a problem, when lights are very bright they need especial components to cope with the heat, there are not cheap and bright, high lumen output.
SMALL LIGHTS
Fenix L1D (1 AA) from 9 lumens up to 90 lumens
POCKET SIZE
Streamlight Poly Pro 4 AA Luxeon 75 lumens
BIGGER THAN POCKET SIZE
Bear Cub rechargeable 220 lumens
CAR SIZE (12 1/2 inches long)
Magcharger 200 lumens
Streamlight Ultra Stinger 295 lumens
BOREALIS rechargeable 1050 lumens
Hope this help[
All the best
