DESIGN AND BUILD

Klein Tools 56040

Built like a work tool. Compact, durable, and designed around functionality — not performance. Magnetic tail cap and laser pointer immediately tell you this is meant for hands-on environments.

Sofirn SP31 V3

Classic tactical flashlight design. Aluminum body, aggressive grip, and dual-switch system — built for control and performance.

If you're working within a broader carry system instead of a single tool, it helps to structure it properly using how to build an edc loadout.

BEAM PERFORMANCE

Klein Tools 56040

350 lumens max output. Enough for:

• Close-up work

• Panel inspections

• Indoor tasks

Not designed for distance or area lighting.

Sofirn SP31 V3

This is a completely different level:

• 2000 lumens

• Strong throw (~250m range)

Built to light up outdoor environments, not just small spaces.

At this level, the difference between usable light and raw output comes down to how it's measured — which is where lumens vs candela explained becomes important

BATTERY AND RUNTIME

Klein Tools 56040

• 6 hours (high)

• 12 hours (low)

• Built-in rechargeable battery

Reliable for a full workday.

Sofirn SP31 V3

• Higher drain at max output

• Much longer runtime on low modes

• Swappable 18650 battery

Better for extended or unpredictable use.

Power systems play a huge role in how these are used day-to-day, especially when comparing edc flashlight battery types.
