To compare flashlights fairly, compare the same operating mode and read lumens, candela, beam distance, and runtime together. Lumens measure total light output; candela measures the beam’s peak intensity; beam distance uses a defined 0.25-lux threshold; and runtime ends when output falls to 10% of its reference level. None of these figures alone tells you how useful a beam will be for your task.
What do flashlight brightness, beam distance, and runtime mean?
Lumens: total light output
Lumens describe the total luminous flux emitted by a light. A higher lumen rating means more total light, but it does not tell you whether that light is spread broadly or concentrated into a narrow beam. The ANSI/PLATO FL1 Standard (2018) defines light output in lumens.

Candela: peak beam intensity
Candela describes luminous intensity, commonly measured at the brightest point along the beam’s central axis. It helps indicate how concentrated the beam is. A flashlight with fewer lumens can still have a higher peak intensity if its light is focused into a narrower beam. FL1 treats peak beam intensity as a separate measure from total output.

Beam distance: reach to a standard threshold
FL1 beam distance is the distance at which the beam reaches 0.25 lux. The ANSI/PLATO FL1 Standard (2018), hosted by Streamlight, defines it as “The distance from the device at which the light beam is 0.25 lux.” This gives manufacturers a reproducible reach measure, not a promise that you will easily identify a person, trail marker, or other target at that distance in every setting.

Peli’s support page also explains the 0.25-lux beam-distance threshold: Peli’s ANSI FL1 guide.
Runtime: time until output drops to 10%
Under the 2018 FL1 definition, runtime starts with the output reading taken 30 seconds after turn-on with fresh batteries. It ends when output falls to 10% of that reference reading. It does not mean the flashlight holds its initial brightness for the entire stated runtime. See the ANSI/PLATO FL1 Standard (2018) for the definitions.

How to compare flashlight specifications fairly
- Choose the task and likely distance. Decide whether you need broad nearby illumination, a concentrated beam for looking farther ahead, or a balance of both.
- Match operating modes. Compare flood with flood, spot with spot, or equivalent settings. A model’s highest figures may belong to a mode that is not comparable to another flashlight’s everyday or flood setting.
- Read the figures together. Use lumens for total output, candela and beam distance for peak intensity and standardized reach, and runtime for the stated mode’s duration to the FL1 endpoint.
- Check the test basis and conditions. Treat figures as FL1-standardized only when the manufacturer identifies them that way. Note battery type or capacity if provided, and do not assume that every product listing follows FL1 testing.
- Consider the beam shape. Petzl notes that lighting distance depends on brightness but mainly on beam shape. A broad beam can make nearby surroundings easier to see, while a concentrated beam sends more light toward a smaller area. The right trade-off depends on the task. Petzl’s headlamp guidance explains the role of beam shape in lighting distance.
A useful comparison table has one row for every mode, not just one row per flashlight. Include the mode name, lumens, candela when published, beam distance, and runtime. Add battery details and a beam description when the manufacturer supplies them; label unavailable or unconfirmed figures rather than filling gaps with assumptions.

Pelican’s official 9050 product page publishes separate specifications for spot/flood, flood, and spot modes. That illustrates why a model name alone is not enough for a fair comparison. The figures below are manufacturer-published specifications; the page does not state a publication date.

What the numbers cannot tell you on their own
- Lumens do not show beam concentration. A high total-output figure alone does not establish how far or narrowly a flashlight will project light.
- Beam distance is not a visibility guarantee. It marks a 0.25-lux threshold, not the point at which every target is easy to recognize.
- Runtime does not mean sustained peak output. The FL1 endpoint allows output to fall to 10% of its initial reference reading.
- Specifications may not share a test basis. Do not treat figures as FL1-tested unless the manufacturer identifies them as such.
