How bright is 250 lumens? Just what is that level of light good for? We give you real life applications and comparisons to help you understand what levels of brightness certain quantities of lumens will deliver.

A Lumen is a measure of the total amount of light emitted from a source.
250 lumens means the light has the intensity of 250 lumens of light.
When you are looking for how bright a certain light bulb or lighting product is, the number of lumens is what you need to use as your comparison.
Lumens is the unit measurement of brightness, with 1 lumen equalling the brightness of 1 candle, so 250 lumens has the brightness of 250 candles.
250 Lumens is a generally regarded as a reasonably low level of light for LED, CFL or incandescent lighting. It’s suitable for accent illumination in shelving and alcoves, and also close up task lighting for reading and kitchen counter tops.
A 250 lumen solar light is a good output for most LED solar lights on the market. Solar lighting lumen outputs range from 10 lm to high powered floodlights at 1000+ lm.
Remember that the higher the brightness, the more power is required from the rechargeable batteries that need to be big enough to power them for a decent amount of time.
Is 250 lumens bright for a flashlight, depends on the activity or task it is required for.
A standard flashlight will have around 100 lumens and used for close up activities it will seem bright enough.
For general use, a flashlight with 400-600 lumens should be bright enough but if you are looking for a headlight for running or cycling, then 250 lumens is good.

The brightness of an 250 lumen torch (UK for flashlight) is the power of light of 250 candles. This level is regarded as a very bright level of torch suitable for most outdoor tasks. The throw of light can be up to approx 250m distance.
To compare how much light you get with different lumens levels, imagine a one by one meter room. If the room has an incandescent bulb which emits 250 lumens then it can illuminate that area to roughly 25 lux (depending on the reflectivity of surfaces in the room).
Is 250 lumens bright, depends on the activity the light is being used for as the feeling of brightness is subjective to the viewer.
LED light is directional and very efficiently delivers light compared to most other light sources. This amount of light is distributed with minimal wastage and creates a brighter intensity on a surface than 250 lumens from other technologies.
LED light when a cool white color temperatures of 4000K to 6500K will feel brighter with the same amount of light when compared to the warmer yellowish tones soft white 2700K and of 3000K warm white.
ANSI lumens is a measure of the brightness of a projector.
250 ANSI lumens has the brightness of 600 lumens LED.
For more see: ANSI Lumens vs Lumens.
250 ANSI lumens is a low level of brightness and only suitable for small projection areas in dark conditions. For comparison, a business projector would need around 3500 lumens to project an image large enough to be seen in a meeting room with some ambient light.
A 250 lumen projector is not going to be very good for anything other than a very small screen in a darkened room.
For general use, you need a projector that emits at least 1000 lumens.

If you are considering is 250 lumens bright enough to read, the answer depends on how close the light is to the page and the surrounding ambient lighting levels.
For general reading purposes a light of around 250-300 lumens will be enough to read by – but if looking at more decorative lighting effects with less of a direct beam of light, such as table lamps or decorative torches, then light losses through shades and diffuser’s needs to be considered and sometimes a higher lumen level of 470 lm would be better.
If you’re looking for a headlamp to wear for running or cycling, then 250 lumens is bright enough. Most lights on the market will give you a choice of different brightness modes, so you can conserve battery life when needed.
In terms of whether 250 lumens is bright enough to see by when running or cycling, it really depends on the conditions. If it’s pitch black then you might want to go for a brighter light, but if there’s some ambient light then 250 lumens should be fine.
A solar light with an output of 250 lumens will be bright enough for most general uses such as accent lighting or close up task lighting. In very dark environments outdoors, this 250lm will be bright enough to light up the objects it is lighting.
A 250 lumen head torch is very good for outdoor activities such as camping and hiking, suitable for all general applications.
A 250 lumen pop up lantern is bright enough to light up a small tent or room and ideal for camping trips.
A 250 lumen solar spotlight is bright and a good strength of light from solar spotlighting. You should look for between 350 lumens and 800 lumens per solar spotlight for a strong illumination of trees and planting.
A 250 lumen solar pathway light is good for waymarking across paths and driveways, when each solor light is spaced approximately 5ft apart.
A 250 lumen LED candleabra bulb is a good brightness for general lighting and can be used as an accent light in some situations. Usually a clear glass design with filament LED light sources.
An 250 lumens per metre LED strip is not a commonly found output unless dimmed to this output. A white light single color LED strip starts at approximately 400 lumens per metre with a wattage of 4.8W/m.
250 lumens from 2.5W LED light is approximately equal to a 20W of incandescent light.
When comparing lumens to watts you need to consider the type of light source being used as the greater the efficiency the higher the lumen level created per watt of power used.
Although wattages are often used when describing how bright a bulb is, lumens are a better measurement.
Useful comparative measurements often asked:
Lux can only be measured by knowing the distance and the area the lumens have to travel to.
250 lumens is 250 candles.
A degree of kelvin is the unit of measurement for color temperature, therefore there is no direct comparison with kelvin to lumen. However, an impression of brightness will increase with a high degree of kelvin as the light seems colder and brighter to the viewer.
Lumens and Candela. Lumens is the total amount of light from a fixture. Candela is how much of that light from a fixture shines in one direction. So 250 lm would be less than 250 candela with the candela only quantified if the angle of beam width is known.
