Headlamps

Headlamps: Hands‑Free Light That Goes Where You Look

Headlamps are compact LED lights worn on the head, ideal for tasks where you need both hands free. Choose a model based on beam pattern (spot vs. flood), output in lumens, runtime and regulation, battery type, comfort, and durability ratings.

When to Choose a Headlamp

• Use if: you need hands-free work light, stable illumination while moving, or precise beam placement for repairs, hiking, or running.
• Avoid if: you need broad ambient light for groups (choose a lantern) or maximum throw at long distances (choose a handheld flashlight with a larger reflector).

Beam Pattern and Output

Beam determines how you see:

• Flood: wide, even light for close work, tents, engine bays, and reading.
• Spot: a tighter hotspot for distance on trails or search tasks.
• Mixed beams are most versatile—wide spill plus a center hotspot.

Recommended lumens by task (approximate):

• Camp chores, reading: 20–100 lm
• Hiking and general use: 150–400 lm
• Running or biking at speed: 300–800+ lm
• Search/inspection bursts: 800–1500+ lm (expect thermal step‑downs)

Runtime and Regulation

Regulated headlamps maintain a steady brightness for longer, rather than spiking and dimming quickly. Actual runtime depends on battery size, mode, temperature, and thermal limits.

Cold reduces runtime. For winter, use lithium primary AA/AAA or keep Li‑ion warm in a pocket with a cable to the lamp if supported.

Power Options: Pros and Tradeoffs

Fit and Comfort

• Weight: ≤3 oz (≈85 g) feels best for running; heavier lights benefit from a top strap or rear battery pack for balance.
• Tilt/pivot: lets you aim without straining your neck.
• Band: soft, washable straps reduce sweat buildup; silicone lining helps grip helmets.
• Helmet use: look for hard‑hat clips or compatible mounts.

Useful Modes and Features

• Red light: preserves night vision and reduces glare at camp.
• Lockout: prevents accidental activation in packs and pockets.
• Mode memory: returns to your last brightness setting.
• High CRI (≥90): improves color accuracy for wiring and inspection.
• Beacon/strobe: emergency signaling; use deliberately.

Durability and Weather Resistance

• IPX4: rain/splash; IPX6: heavy spray; IPX8: submersion. Dry charging ports before use.
• Drop rating matters for job sites; look for 1–2 m tested bodies.
• Materials: chemical‑resistant housings for oily or solvent‑heavy environments.

Quick Picks by Activity

• Running: 200–400 lm mixed beam; ≤3 oz; balanced headband; IPX4+; 2–5 h at ~200 lm.
• Camping/hiking: 150–300 lm flood; red mode; IPX4–6; 20–100+ h on low (5–20 lm).
• Work/repairs: 400–800 lm flood; high CRI; tilt and helmet clips; IPX6; USB‑C or 18650.
• Emergency kit: simple switch, lockout, lithium AA/AAA for shelf life; spare cells secured to the strap.
• Search/inspection: 800–1500 lm spot bursts; 18650/21700; expect thermal step‑down.

Safety and Care

• Use quality cells; do not mix old and new batteries or chemistries.
• Do not charge Li‑ion while wearing the headlamp or when wet.
• Store Li‑ion at ~40–60% charge; check every 3–6 months.
• Rinse dust/salt, dry fully, and lock out before packing.

FAQ

• How many lumens do I need? 20–100 lm for camp tasks, 150–400 lm for hiking, 300–800+ lm for running or fast movement.
• Which beam is best? Flood for close work and comfort; spot for distance. A mixed beam covers most needs.
• Rechargeable or replaceable batteries? Rechargeables suit daily use; AA/AAA are best for long trips or emergency storage.
• Are headlamps waterproof? Check the IP rating. IPX4 handles rain; IPX8 can survive submersion. Always dry charging ports.
• What about cold weather? Lithium primary AA/AAA and warm‑kept Li‑ion cells retain power better in the cold.
