Do You Need a Moonlight Mode?

The short answer

This page exists because the mode is almost never explained and frequently not published. It is a real feature with a measurable benefit for some people and complete irrelevance for others, and the specification that tells you which you are is not the lumen figure.

What counts as a moonlight mode

There is no standard and no ANSI definition, so the term is used loosely. In practice the enthusiast meaning is a mode at or below about 10 lumens, with the genuinely low ones under 1 lumen. The test that matters is not the number itself but what the number does: at 5 lumens a light reads as a warm glow that lets you move around a dark room without waking anyone and without contracting your own pupils, and it draws so little current that the runtime becomes absurd.

Which is why a 50-lumen "low" is not a moonlight mode, and it is worth saying plainly because manufacturers use the words interchangeably. Streamlight publishes 50 lumens for 3.5 hours as the MicroStream's low. That is a perfectly good low mode for walking. It is roughly ten times too bright to be a moonlight mode and it runs for about one sixtieth as long as one.

The numbers, from the manufacturers that publish them

Two hundred and twenty-five hours is nine and a half days of continuous light from a lamp that weighs 86 grams. That figure, and not the 400 lumens on the front of the box, is the reason to own the thing.

Who this is actually for

• Anyone moving around a house at night with other people asleep. Five lumens shows you a hallway and a stair edge without waking anyone and without blinding you back into the dark when you switch off.
• Campers and anyone in a shared tent, hut or hide, where a 400-lumen burst is an antisocial act.
• Parents checking on a sleeping child, which is the use case nobody puts on the packaging and nearly everybody has.
• Anyone who keeps a light for emergencies. A mode that runs for days turns a flashlight into something you can leave on through a night-long outage rather than ration.
• Astronomers and anyone whose dark adaptation is the point, although for that job a red mode is better still.

And who it is not for: if your flashlight is a tool you carry to a job, point at something, and put away, the moonlight mode is a setting you will cycle past with mild irritation. There is nothing wrong with that — it is just not a feature worth paying for or compromising the interface for.

Prices pulled October 18, 2026. Lumens per dollar is the manufacturer's published maximum output divided by that price, recomputed every time the price moves.

The catch: reaching it

A moonlight mode has one implementation detail that decides whether it is usable, and it is the same detail that decides red modes. If you have to cycle up through 400 lumens to get down to 5, you have blinded yourself and everyone near you on the way, which defeats the purpose every single time.

What to look for is a direct route: a long press from off that goes straight to the lowest mode, which is how most ramping firmware behaves, or a dedicated ultralow position. Lights running Anduril firmware — Sofirn and Wurkkos models, among others — reach moonlight with a press-and-hold from off, and can ramp below the lowest fixed step. That flexibility is the single best argument for Anduril, and our guide to choosing a flashlight covers the cost of it, which is a week of confusion.

1. Most output from a flat pocket body

NITECORE EDC31

Lumens per dollar

64

Thirty-five hundred lumens and 35,630 candela out of a 113-millimeter flat body, with IP68 to two meters and a 2-meter impact rating. NITECORE publishes the figures that describe the beam and then publishes a runtime for exactly one of its four modes, which is the pattern that keeps this brand off the top of our tables.

Max output

3,500 lm

Runtime

57 h at 5 lm

Battery

Sealed

Water rating

IP68

What it gets right

• Thirty-five hundred lumens and 380 meters from a body that still fits a pocket
• IP68 to two meters plus a 2-meter impact rating — the strongest pair NITECORE publishes here
• Publishes peak beam intensity in candela, which is the figure that actually governs throw
• Fifty-seven hours at 5 lumens makes it usable as a long-reserve light as well as a bright one

What it gets wrong

• The 3,800 mAh 18650 is built in and NITECORE states it is non-removable, so the light has a service life
• A runtime is published for the ultralow mode only — nothing for the three modes you will actually use
• Three and a half thousand lumens in a 100-gram body is a burst, and NITECORE does not say how long it lasts
• Two separate momentary modes on top of four levels is a lot of interface for a pocket light

Published specification

• Maximum output: 3,500 lumens — NITECORE published specification
• Peak beam intensity: 35,630 cd — NITECORE published specification
• Beam distance: 380 m — NITECORE published specification
• Maximum runtime: 57 hours at 5 lumens — NITECORE published specification
• Battery: Built-in 3,800 mAh 18650 Li-ion, non-removable — NITECORE published specification
• Charge time: About 1 h 45 min with a 5V/2A adapter — NITECORE published specification
• Water rating: IP68, submersible to 2 m — NITECORE published specification
• Impact: 2 m — NITECORE published specification
• Weight: 100 g (3.53 oz) — NITECORE published specification
• Length: 113.2 mm (4.46 in) — NITECORE published specification
• Emitter: NiteLab UHi 20 MAX — NITECORE published specification
• Per-mode runtime: Not published except the 5-lumen ultralow

Skip this one if

you want to re-cell the light rather than replace it. NITECORE states the 18650 is non-removable, which on an otherwise excellent specification is the one thing you cannot work around.

Buy it if: somebody who wants the most output and throw available in a flat pocket body and is willing to treat the light as a consumable to get it.

2. Smallest light in the range

NITECORE Tiki LE

Lumens per dollar

15

Ten and a half grams and 55 millimeters, for 300 lumens, 71 meters and auxiliary red and blue LEDs. It is genuinely the size of a keyring fob. The cell is a built-in 130 mAh, which at that capacity makes the light a consumable rather than a tool — the same objection we raise against every sealed keychain light, including Olight's.

Max output

300 lm

Runtime

40 h at its lowest mode

Battery

Sealed

Water rating

IP66

What it gets right

• Ten and a half grams and 55 millimeters — small enough that it genuinely is not noticed on a keyring
• Three hundred lumens and 71 meters is a real beam, not a token one, at this size
• Auxiliary red and blue LEDs on a light this small, with the candela figure published
• USB-C charging straight into the body, so it needs nothing you do not already carry

What it gets wrong

• The 130 mAh cell is built in, so the light is a consumable with a service life, not a tool you keep
• IP66 is the weakest water rating of any NITECORE here — rain yes, submersion no
• No runtime is published beside 300 lumens; only the 40-hour maximum is given
• At 130 mAh the high mode cannot last long, and NITECORE does not say how long

Published specification

• Maximum output: 300 lumens — NITECORE published specification
• Peak beam intensity: 1,260 cd — NITECORE published specification
• Beam distance: 71 m — NITECORE published specification
• Maximum runtime: 40 hours — NITECORE published specification
• Battery: Built-in 130 mAh Li-ion, USB-C charging — NITECORE published specification
• Water rating: IP66 — NITECORE published specification
• Impact: 1 m — NITECORE published specification
• Weight: 10.5 g (0.37 oz) — NITECORE published specification
• Length: 55 mm (2.17 in) — NITECORE published specification
• Head diameter: 14.7 mm (0.58 in) — NITECORE published specification
• Emitter: OSRAM P8, plus an auxiliary red LED and an auxiliary blue LED — NITECORE published specification
• Per-mode runtime: Not published on the product page — only the 40-hour maximum is given

Skip this one if

you want to keep the light. A built-in 130 mAh cell is the smallest battery on this site, and when it reaches the end of its cycles the whole light is refuse. For a keychain light with a cell you can swap, the Sofirn SC21 Pro takes a standard 16340.

Buy it if: a keyring, a coin pocket or a bag liner — somewhere a light has to be present and completely unnoticed.

3. Best hybrid headlamp at the lower price

Petzl TIKKA CORE

Lumens per dollar

8

The ACTIK CORE's argument in a cheaper, lighter package: 450 lumens stated to ANSI/PLATO FL1, 84 grams, and the same CORE pack or three AAA cells when the pack is flat. Petzl publishes a lumen figure, a beam distance and a burn time for every mode on both power sources, which almost nobody else does even once.

Max output

450 lm

Runtime

2 h 30 min at 450 lm; 110 h at 7 lm

Battery

Replaceable cell

Water rating

IPX4

What it gets right

• Lumens, beam distance and burn time published for every mode on BOTH power sources
• States ANSI/PLATO FL 1 conformity, which most brands at this price do not
• Runs on three AAA cells when the CORE pack is flat, with no adapter to lose
• One hundred and ten hours at 7 lumens is a genuine emergency reserve

What it gets wrong

• IPX4 — weather resistant, not submersible
• Four hundred and fifty lumens is modest against lamps at similar money
• Output drops to 350 lumens on AAA cells, which Petzl states but buyers miss
• The CORE pack is a Petzl part rather than a standard cell

Published specification

• Maximum output: 450 lumens (ANSI/PLATO FL 1) — Petzl published specification
• MAX POWER on CORE: 450 lumens, 75 m, 2 h 30 min — Petzl published specification
• MAX POWER on AAA: 350 lumens, 70 m, 2 hours — Petzl published specification
• STANDARD on CORE: 100 lumens, 45 m, 7 hours — Petzl published specification
• STANDARD on AAA: 100 lumens, 45 m, 12 hours — Petzl published specification
• MAX BURN TIME: 7 lumens, 10 m, 110 hours on either source — Petzl published specification
• Red lighting: 2 lumens, 5 m, 60 hours continuous — Petzl published specification
• Battery: CORE 1,250 mAh / 3.6 V / 4.5 Wh, or 3 x AAA — Petzl published specification
• Weight: 84 g — Petzl published specification
• Water rating: IPX4, weather resistant — Petzl published specification
• Warranty: Lamp 5 years; CORE battery 2 years or 300 cycles — Petzl published specification

Skip this one if

you want maximum output for the money. This lamp spends its budget on documentation, hybrid power and a five-year warranty, and a budget rechargeable will out-lumen it for less.

Buy it if: anyone who wants Petzl's hybrid-power argument without paying for the ACTIK CORE's extra output.

4. Most complete published runtime table

Black Diamond Spot 400-R

Lumens per dollar

7

Four hundred lumens for four hours, 200 for eight, 6 for two hundred and twenty-five. Black Diamond publishes lumens, runtime and beam distance for all three modes, and IP67 on top. There is nothing to guess at here.

Max output

400 lm

Runtime

4 h

Battery

Sealed

Water rating

IP67

What it gets right

• Lumens, runtime and distance published for every mode
• Two hundred and twenty-five hours on low is a genuine emergency reserve
• IP67 and a battery meter that shows an actual percentage

What it gets wrong

• Micro-USB in a year when everything else is USB-C
• Integrated battery — no spare, no re-cell
• Eighty-six grams is heavy next to the ultralight class

Published specification

• High: 400 lumens, 4 hours, 100 m — Black Diamond published specification
• Medium: 200 lumens, 8 hours, 60 m — Black Diamond published specification
• Low: 6 lumens, 225 hours, 12 m — Black Diamond published specification
• Battery: Integrated 1,500 mAh Li-ion, micro-USB — Black Diamond published specification
• Water rating: IP67, tested to 1.0 m for 30 minutes — Black Diamond published specification
• Weight: 86 g — Black Diamond published specification

Skip this one if

you have standardized on USB-C. Carrying a second cable for one device is a small annoyance that compounds on a long trip.

Buy it if: camp, dog walks and anyone who wants a headlamp whose numbers are all on the box.

5. Best pen-clip light with published runtimes

Streamlight MicroStream USB

Lumens per dollar

7

Two hundred and fifty lumens for an hour and a half, fifty for three and a half, at 1.2 ounces. The battery is sealed, which caps its lifespan, but every other number on the sheet is published and checkable.

Max output

250 lm

Runtime

1 h 30 min

Battery

Water rating

IPX4

What it gets right

• Every mode's runtime is published, which is why it scores well here despite modest output
• Deep pocket clip that actually holds in a shirt pocket
• 1.2 ounces — it is easy to forget you have it

What it gets wrong

• The cell is sealed in; when it fails the light is finished
• IPX4 splash rating only
• 250 lumens is not enough to light a yard

Published specification

• High: 250 lumens, 68 m, 1.5 hours — Streamlight published specification
• Low: 50 lumens, 31 m, 3.5 hours — Streamlight published specification
• Battery: Lithium-ion, charges in-product in 4 hours — Streamlight published specification
• Water rating: IPX4 — Streamlight published specification
• Impact: 1 m tested — Streamlight published specification
• Weight: 1.2 oz (34.1 g) — Streamlight published specification
• Length: 3.87 in (9.83 cm) — Streamlight published specification

Skip this one if

you want a light you can re-cell. For a keychain-sized light with a replaceable battery, look at the Sofirn SC21 Pro instead.

Buy it if: a shirt pocket, a scrubs pocket, or anyone who wants a light without a bulge.

How we ranked these

Published output over live price, as everywhere on this site, with one adjustment stated here: a light that publishes both an output AND a runtime for its lowest mode is scored above one that publishes only a maximum runtime at a mode it does not name. On this page that is the whole subject, so a figure you cannot attribute to a mode earns no credit for it.

What one lumen actually looks like

The reason a sub-lumen mode works at all is that your eyes are not a camera with a fixed sensitivity. In the dark the rods take over from the cones, and after twenty to thirty minutes of adaptation they are extraordinarily sensitive — several orders of magnitude more so than in daylight. A mode that looks like nothing when you switch it on in a lit kitchen is perfectly serviceable once your eyes have caught up.

Which produces the one genuine limitation of the feature, and it is worth knowing before you buy for it. A moonlight mode is useless the moment you come in from somewhere bright. It is a mode for people who are already in the dark and intend to stay there, not a mode for arriving. If your use case is walking out of a lit house into a dark garden, you want 50 to 150 lumens and the moonlight setting will frustrate you.

Moonlight or red?

They solve the same problem differently and the choice is not obvious. A red mode preserves dark adaptation better at the same perceived brightness, because rod cells are far less sensitive to long wavelengths. A very low white mode preserves it slightly less well but shows you color and contrast, which red flattens into a monochrome wash — under red light a red wire and a black wire look identical, and so does a blood spot on a brown carpet.

The rule that falls out of that: red for staying adapted while you do something simple, moonlight for seeing something properly without waking the room. The lamps that offer both — Petzl publishes 7 lumens for 110 hours in white and 2 lumens for 60 hours in red on the TIKKA CORE — let you take the decision per task rather than per purchase, and that is the better arrangement if the lamp is going camping.

Why so few brands publish the figure

Of the forty-nine lights in our registry, four publish both an output and a runtime for a WHITE mode at or below 10 lumens — the NITECORE EDC31 and NU25, Black Diamond's Spot 400-R and Petzl's TIKKA CORE. Three more publish one for a RED mode, which goes lower still: Streamlight gives 0.7 lumens for 192 hours on the Siege AA. Several publish a long maximum runtime with no mode attached: NITECORE gives 650 hours for the MH25 Pro and 40 hours for the Tiki LE without naming the mode either figure belongs to, and a runtime you cannot attach to an output is not a specification you can shop on.

The commercial reason is straightforward. A headline runtime looks impressive on a listing and costs nothing to print; a full mode table invites comparison and takes work to produce. It is the same pattern as the missing turbo runtime, running in the opposite direction, and it is the reason this site reads the whole table rather than the front of the box.

What we cannot tell you

We have not measured any of these modes. We cannot tell you how 5 lumens from a NITECORE compares with 6 from a Black Diamond in a dark room, whether either figure is accurate, how the tint reads at very low drive currents, or how the runtime behaves once a cell has aged. Every figure here is published by the manufacturer named beside it, and the judgment that 10 lumens is the sensible dividing line is ours rather than a standard.
