Buy one headlamp for walking and one small light for the tent, or buy a hybrid that does both. The single most useful spec is not lumens — it is regulated runtime at 150 lumens, which is the output you actually use on a trail. A lamp that holds 150 lm for six hours beats one that hits 800 lm for ninety seconds.
The four use cases
| Use case | Lumens | Runtime needed | Beam | Typical price |
|---|---|---|---|---|
| Trail walking | 150–300 | 5–8 h | Spot or hybrid | $30–60 |
| Camp tasks / cooking | 50–150 | 8–12 h | Flood | $20–45 |
| Tent reading | 5–30 | 10–20 h | Flood, warm or red | $15–35 |
| Repairs / route finding | 300–500 | 2–4 h | Spot | $40–80 |
One hybrid lamp at 300 lm with a 40 h low mode covers all four; a separate tiny tent light is a comfort upgrade, not a necessity.
Lumens: the useful range
| Output | Sees | Battery cost |
|---|---|---|
| 5–20 lm | 2–5 m | Very low |
| 50–100 lm | 10–20 m | Low |
| 150–300 lm | 30–60 m | Moderate |
| 400 lm+ | 60–100 m | High, short bursts only |
Above 300 lm the battery drains fast enough that the lamp becomes a 10-minute tool. For camping, 300 lm is the practical ceiling.
Runtime: read the regulated figure
| Battery capacity | 50 lm | 150 lm | 300 lm |
|---|---|---|---|
| 1,000 mAh | 8–12 h | 3–4 h | 1.5–2 h |
| 1,500 mAh | 12–18 h | 4–6 h | 2–3 h |
| 3,000 mAh | 25–35 h | 9–12 h | 4–6 h |
Manufacturers quote the lowest mode. Look for “regulated” output, which holds brightness as the battery drains instead of dimming gradually.
Battery type
| Type | Weight | Cold | Replaceable | Verdict |
|---|---|---|---|---|
| AAA ×3 | 1.2 oz cells | Poor | Anywhere | Best backup |
| AA ×3 | 2.4 oz | Fair | Anywhere | Long trips |
| Built-in Li-ion | Lightest | Drops 30–50% | No | Summer |
| 18650 | Medium | Good | Yes | Winter, long trips |
| USB-C built-in | Light | Drops in cold | No | Weekend |
For winter camping, a removable 18650 or lithium AA is the reliable choice; keep the spare cell inside your jacket.
Weight and price
| Tier | Weight | Price | What you get |
|---|---|---|---|
| Budget | 2–3 oz | $15–25 | 150–250 lm, AAA, basic modes |
| Mid | 2.5–3.5 oz | $30–50 | 300–400 lm, USB-C, red mode |
| Premium | 3–5 oz | $60–90 | 500 lm+, regulated, IPX7, 18650 |
Top picks by use case
| Use case | Spec to look for | Price target |
|---|---|---|
| Best overall | 300–400 lm, USB-C, red mode, 3 oz | $35–50 |
| Best for winter | 18650 removable, regulated, IPX7 | $60–80 |
| Best budget | 200 lm, AAA, 2 oz | $15–25 |
| Best for tent | 20 lm, warm or red, 1 oz | $15–25 |
| Best for repairs | 500 lm spot, lock mode | $50–80 |
Two features worth paying for
- Lock mode. A long-press lock stops the lamp turning on in your pack and dying before dark.
- Glove-friendly button. A recessed micro-button is unusable in winter gloves.
Neither appears in the lumen rating, and both matter more than 100 extra lumens.
Four buying mistakes
Buying lumens instead of runtime. A 1,000 lm lamp with a 45-minute turbo mode is a toy; a 300 lm lamp that holds output for six hours is a tool. Read the regulated runtime at 150 lm.
Ignoring the beam pattern. A pure spot beam lights 50 m ahead and nothing at your feet — useless for cooking. A hybrid with flood and spot covers both.
Skipping the lock mode. Lamps without a lock turn on in the pack, and a dead lamp at 2 a.m. is worse than a dim one.
Mismatching batteries across the kit. Three headlamps with three different cell types means three spare sets and two chargers.
How to test a headlamp in the shop
- Turn it on low and look at the beam on a wall — is the hotspot usable at 1 m?
- Cycle the modes with gloves on, or with your hands behind your back.
- Check the weight on a scale, not the spec sheet.
- Look for a lock mode in the manual.
- Confirm the battery is replaceable or the cable is standard USB-C.
Five minutes in the shop beats a return from the trailhead.
Spare batteries versus a spare lamp
A spare battery set costs $4 and weighs 1 oz; a spare lamp costs $20 and weighs 2 oz. Carry both for a group, and for solo trips carry the batteries and accept the risk. The exception is winter, where cold kills cells regardless of charge — a spare lamp is worth the weight.
