Surefire, always the best - SureFire Weapon M900L Vertical Foregrip LED WeaponLight

Surefire products are great quality.I keep going back to them.I love the small lights on each side that can light up the stairs you are descending without giving away your position. The 500 lumen is blinding.
Pros: Super Bright, sturdy, easy to setup
Cons: expensive
