Best headlamps under $100

Black Diamond Spot Headlamp

Black Diamond's long-running all-rounder, rebuilt around a dual lens design that pairs a flood lens for camp chores with a spot lens for seeing down the trail, plus red, green and blue night vision modes. The Dual-Fuel design is the real draw: it runs on three AAA batteries out of the box, or on Black Diamond's rechargeable BD 1500 pack, which charges through the lamp over USB-C. That flexibility, plus an IPX7 housing that survives a dunk, makes it a sensible pick for multi-day trips where you cannot count on a plug. The catch is that the rechargeable battery is sold separately, so the sticker price is not the whole cost if you want to charge it.

Black Diamond Storm Headlamp

The rugged, waterproof end of Black Diamond's line: 550 lumens in an IP67 sealed housing that shrugs off dust and a 30 minute dunk, with oversized buttons you can work while wearing gloves. It is the one to reach for on technical, all-weather nights, and it adds red, green and blue modes plus mode memory, so it wakes at the brightness you left it. Reviewers on Black Diamond's own product page praise the reworked interface and the now-replaceable mount, but note the light is unregulated, so it dims steadily through its run and the quoted burn times flatter it. At 102 grams it is also the heaviest Black Diamond here.

Black Diamond Astro 300-R Headlamp

Black Diamond's simplest rechargeable headlamp: one button, 300 lumens and an integrated 1500 mAh battery, aimed at campers and around-the-house use rather than technical nights out. The low setting is the headline number, running 140 hours, which is longer than almost anything else at this price. Its weaknesses are the ones you would expect from the cheapest rechargeable in the range: an IPX4 rating that handles rain and sleet but not submersion, and a micro-USB charge port rather than USB-C, which is an increasingly awkward cable to have to pack.

Petzl ACTIK CORE

Near the top of this price range, and the lamp most often recommended for long trips, pairing 625 lumens with Petzl's HYBRID CONCEPT: it ships with the rechargeable CORE battery, also takes three AAAs, and detects which is installed. A mixed beam covers both close work and distance, the reflective headband and phosphorescent reflector are genuinely useful in the dark, and the five year lamp warranty is the longest in this set. The compromise is weather sealing: at IPX4 it is rain resistant only, so it is the wrong choice if you expect your lamp to go swimming.

Petzl TIKKINA

The cheapest lamp in this comparison by a wide margin, and a deliberately plain one: 300 lumens, a single button, a wide flood beam and no red mode. It ships with three AAA batteries but accepts Petzl's CORE rechargeable pack later, so it can become a rechargeable lamp without buying a new light. At 92 grams it is not light for what it does, and IPX4 means rain only, but as a spare for a glovebox, a kid or a guest it is hard to argue with the price.

Petzl SWIFT LT

At 43 grams this is the lightest lamp here by a wide margin, built for people counting grams: runners, fastpackers and anyone who wants a lamp that disappears in a pack. It still puts out 380 lumens across three white levels plus a red mode, charges over USB-C, and uses a thin, breathable headband that stays put on the move. The trade-offs are real: IPX4 weather resistance, a 70 meter reach that is short next to the brighter lamps here, and no option to fall back on disposable batteries when the charge runs out.

Nitecore NU27

The value standout of this group: 600 lumens for under $45 in a 56 gram body, with switchable warm, neutral and cool color temperatures, which is rare at any price. Warm light at 3000K cuts through fog and rain, the cool setting is better on open ground, and a separate red mode preserves night vision. Buyers on Nitecore's store praise the weight and the battery life; the recurring complaint is a boxy beam with hard edges that is distracting indoors, and one reviewer reported a red LED that did not work. IP66 means it handles heavy spray but is not meant to be submerged.

Nitecore NU25 MCT UL

The ultralight backpacker's default, and the cheapest way into a genuinely capable lightweight lamp: 400 lumens from a 47 gram body that uses adjustable elastic cords in place of a woven headband. Like the NU27 it offers warm, neutral and cool white plus a red mode, charges over USB-C in a little over an hour, and holds a claimed 45 hours on its lowest setting. Its throw is the longer of the two Nitecores at 132 meters despite the lower output, because the beam is focused more tightly. The limit is weather sealing: IP66 covers heavy spray and dust, but unlike the BioLite and Ledlenser lamps here it is not meant to be submerged.

Fenix HM50R V2.0

The brightest lamp here at 700 lumens, and one of the few built around a swappable cell rather than a sealed battery: it ships with a rechargeable 16340 that charges over USB-C, and will also run on a non-rechargeable CR123A, though Fenix notes that only low and medium white modes are reachable on one. It is rated IP68 and impact resistant to two meters, which puts it at the tough end of this group and explains why it turns up on caving and hunting lists. At 78 grams with battery and headband it is light for its output, but the 42 hour maximum runtime is short next to the lamps that idle for 100 hours or more.

BioLite Range 500

BioLite's pitch is charging speed and comfort: the Range 500 goes from empty to 80 percent in 30 minutes over USB-C, or gains an hour of light in eight minutes, which suits people who charge in snatches between days out. The battery and the light sit together in one slim front unit on an integrated band, rather than in a rear battery pack, and the IP67 rating means it survives being dropped in a creek. 500 lumens and a 100 meter beam are mid-pack numbers here, while 200 hours on low is among the best. It is the priciest BioLite in this set, and the fast-charge advantage only pays off if you have power nearby.

BioLite Range 300

The stripped-down Range: 300 lumens, two lighting modes instead of five and no red flood, at 52 grams and under $40. It keeps the parts that make the line worth buying, namely the 30 minute fast charge, the IP67 submersible rating and the same one-piece band, which makes it the cheapest fully waterproof lamp in this comparison. If you mostly need light around camp and on easy trail, the missing modes will not be missed. If you want red light to protect your night vision or to avoid blinding a tentmate, step up to the 500.

Ledlenser HF6R Signature

The brightest lamp in this comparison by a wide margin: 1000 lumens in an IP68 aluminum housing rated for continuous immersion rather than a brief dunk. Its distinguishing feature is Ledlenser's focus wheel, which slides the beam from a wide flood to a 170 meter spot, the longest reach here, and it adds green and blue modes alongside red for hunting and tracking. The price of all that is weight: at 135 grams it is the heaviest lamp here, roughly three times the Petzl SWIFT LT. It also charges by a proprietary magnetic cable rather than a USB-C socket on the lamp itself, so losing the cable is a real problem on a long trip. Ledlenser's own store was discounting it well below the $89.95 list price when this was researched.
