A flood beam spreads light across a nearby area; a throw beam concentrates it to illuminate farther away. Choose flood for close work and awareness of your surroundings, throw for spotting at a distance, or a flashlight with both modes if you need to switch between those tasks. When comparing reach, check peak candela and standardized beam distance—not lumens alone.
What makes a flashlight beam flood or throw?
Flood: broad coverage nearby
A flood beam distributes light across a wider area, making it useful for illuminating a work surface, walking nearby, or seeing more of the surroundings at once. Its broad coverage is the priority, rather than concentrating the brightest part of the beam far ahead.
Throw: concentrated light for distance
A throw-oriented beam puts more intensity into its central area so it can reach farther. That concentrated hotspot helps when looking across open ground or toward a distant object, but it covers less of the immediate scene than a broad flood beam.

Which beam should you choose?
| Task | Beam to prioritize | Why |
|---|---|---|
| Close-up repairs or work | Flood | Broad nearby coverage helps light the work area. |
| Walking or general awareness | Flood | A wider beam helps illuminate more of the nearby surroundings. |
| Spotting across open distance | Throw | Higher central intensity and greater beam distance are more relevant to reach. |
| Switching between close tasks and distant spotting | Dual-mode flood/spot | Separate modes can serve different tasks without requiring one beam pattern to do both. |
How to read flashlight specifications
Lumens measure total output
Lumens describe the total quantity of light emitted. A larger lumen figure does not, by itself, tell you how far the beam reaches: a broad beam can spread light over a large nearby area, while a more concentrated beam can direct more intensity toward the center. ANSI/PLATO’s 2018 FL1 standard summary defines light output in lumens.
Candela describes peak beam intensity
Peak beam intensity is the maximum luminous intensity, typically along the central axis of the light cone, and is reported in candela. When distance is important, compare candela as well as lumens. A higher peak intensity generally indicates a stronger central beam; it does not describe how broadly the rest of the scene is illuminated.

FL1 beam distance gives a standardized comparison point
Under the ANSI/PLATO FL1 definition, beam distance is the distance at which the beam reaches 0.25 lux. The standard reports this distance in meters. Treat it as a consistent specification for comparing lights, not a guarantee that you will clearly identify every target at that distance: visibility also depends on the target and scene.

Rank #3
- The output of the green beam is ≤5mW, the class is 3R
- [4 Lights, 7 Configurations] The EDC Flashlight is an upgraded version of Arkfeld Ultra, combining 1700 lumens of Pure Flood, 800 lumens of spotlight, 365nm UV light, and green beam in one flashlight. The Pure Flood offers a wide, soft and seamless beam for daily use, camping, and night walks. The spotlight is focused and powerful to see farther and clearer, ideal for hiking, emergency situations. The UV light has low/high modes to reveal stains, detect leaks, and create glowing effects. Four lights work independently, and the green beam pairs with any of the 3 to get 7 combinations, ideal for presentation and position marking tasks
- [Exceedingly Pre-durable Material] Made from Olight's O-aluminum, which is 1.73x as hard as standard 6061 aluminum alloy, the handheld flashlight defies scratches, resists breaking, and shrugs off dents
- [Olight's Self-Developed LED] ArkPro Ultra features a proprietary EIP 1 LED chip, which creates an expansive, crystal clear beam that is evenly distributed. It offers a wide view of surroundings, while being more efficient than the others, making it reliable for everyday carry, outdoor adventures
- [Dual Charging Options and Battery Info] The LED flashlight works with a magnetic USB charging cable or a USB-C cable. When fully charged, it can provide up to 14 days of continuous use on moonlight mode. In addition, two color indicators separately show brightness levels in white and battery levels in green. The new lockout indicator takes the guesswork out of safety, offering a quiet cue that the flashlight is in lockout mode. It is equipped with a built-in rechargeable lithium polymer battery (non-removable, permanently integrated into the flashlight body)
One light can offer both flood and throw
Some flashlights provide separate flood and spot modes. Pelican’s manufacturer-published specifications for its 9050 illustrate the trade-off: its flood mode has a shorter listed beam distance and lower peak intensity than its spot mode, while its spot/flood mode combines different output and reach figures. These are product-page specifications, not independent test results.
| Pelican 9050 mode | Output | Runtime | FL1 beam distance | Peak beam intensity |
|---|---|---|---|---|
| Spot/flood | 3,369 lumens | 2 h 45 min | 417 m | 43,568 cd |
| Flood | 1,119 lumens | 5 h 30 min | 47 m | 559 cd |
| Spot | 2,623 lumens | 4 h 15 min | 489 m | 59,760 cd |
The example shows why mode matters: the flood setting favors a wide nearby beam, while the spot setting publishes much higher peak intensity and longer distance. A combined mode has its own specifications rather than simply matching either setting. Confirm current specifications on the Pelican 9050 product page before relying on them.

A practical comparison checklist
- Start with the task: decide whether broad nearby coverage, distant spotting, or both matter most.
- Check the beam pattern and modes: look for a flood, spot, or switchable combination rather than inferring the pattern from output alone.
- Compare lumens and candela together: lumens describe total output; candela describes peak central intensity.
- Use FL1 beam distance as a comparison: remember its 0.25-lux threshold and do not treat it as a target-identification guarantee.
- Check runtime, impact resistance, and water resistance: these matter for the conditions and duration of use; confirm which figures and test icons the manufacturer provides.
As Streamlight sales manager Brett Marquardt puts it, “The amount of light (lumens) and the beam’s down range throw (candela), should be determined by what your application is, as opposed to “bigger is better”.” Streamlight’s explanation of candela versus lumens was published on August 5, 2024.
