Light

Light Output

Lumens: Total light output. More lumens = brighter, but not always better. 500-1000 lumens is adequate for most uses.

Candela: Beam intensity/throw. High candela = focused beam that reaches further. Important for outdoor use.

Both matter: A high-lumen, low-candela light floods an area but doesn't reach far. High candela with lower lumens creates a spotlight effect.

Beam Patterns

Flood: Wide beam illuminating a large area. Good for room clearing and close range.

Throw: Tight beam reaching long distance. Better for outdoors and longer range identification.

Balanced: Combination of both. Most weapon lights offer a balanced pattern with hot center and spill.

Switch Options

Tail Cap: Traditional location at rear of light body. Click for constant on, press for momentary.

Pressure Pad: Remote switch for activation without shifting grip. Essential for rifle WMLs.

Push Button: Some lights have body-mounted buttons. Less common for rifle use.

Dual Fuel/Multi-Function: Switches offering both momentary and constant-on, sometimes with program modes.

Mounting

Picatinny: Most common. Rock solid and universal.

M-LOK: Direct mount saves rail space. Adapters available for most lights.

Scout Pattern: Standardized mounting used by SureFire and compatible lights. Allows easy head and body swapping.

Power Source

CR123A: High energy density, long shelf life. The standard for quality WMLs.

18650 Rechargeable: More economical long-term. Ensure your light is rated for 18650 voltage.

AA/AAA: Some lights accept common batteries. Less power but more available.

Quality Indicators

• Survives recoil (many cheap lights don't)
• Consistent output throughout battery life
• Robust switch that doesn't fail
• Quality lens that doesn't cloud or crack
• Solid lockup on mount

Selection Guidelines

For a defensive rifle, prioritize reliability over features. Proven options include:

• Budget: Streamlight ProTac, Cloud Defensive OWL
• Mid-range: Modlite, Arisaka
• Premium: SureFire Scout Pro, Cloud REIN

Get a quality pressure switch mounted where your support hand naturally falls. This is a critical defensive component—don't cheap out on something this important.
