How bright is 1800 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.
Table of Contents
A Lumen is a measure of the total amount of light emitted from a source.
1800 lumens means the light has the intensity of 1800 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 1800 lumens has the brightness of 1800 candles.
1800 Lumens is a good level of light for any individual sources of light. It’s more suitable for commercial recessed lighting, commercial downlighting and up lighting and for entry level exterior security and outdoor flood lighting.

A 1800 lumen solar light is going to be brighter than most LED solar lights on the market. 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.
An output of 1800 lumens is bright enough to provide illumination for a large area such as a driveway, garden or patio.
The brightness of a flashlight is rated in lumens. A standard flashlight will have around 50 to 100 lumens.
For general use, a torch with 400-600 lumens should be bright enough but if you are looking for a strong headlight or tactical flashlight then 1800 lumens provides strong penetrating searchlight.
The brightness of an 1800 lumen torch (UK for flashlight) is the power of light of 1800 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 a 200m distance depending on the beam width of light.
A 1800 lumen LED flood light is bright enough for most applications. A 1800 lumens LED bulb will provide a very bright level of illumination with just one source, and therefore it’s best used once the need for lighting multiple sources has been eliminated by installing suitable fixtures such as recessed lights or track lighting to distribute the light around the room.
A bike light with an output of 1800 lumens is very bright and would be more than enough for most situations where you want to be seen rather than rely on lighting up the road in front of you.
If you are riding at night on unlit roads or trails where there are no streetlights then it makes sense to have the brightest illumination possible so that you can see everything in front of you.
If you want to watch movies on a big screen in a dark room, you will need a projector that is bright enough but does not need to be of the brightest specification. For screens that are 100”~120”, 2,000 lumens is ideal but if there is ambient light or if there are bright light sources in the room, you will need a projector with 3,000 lumens or more.

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 1000 lumens then it can illuminate that area to roughly 180 lux (depending on the reflectivity of surfaces in the room).
A 1800 lumen LED is a very bright light source, and is likely to be too bright for some applications. For example, it would be too harsh for general room lighting where a more subtle level of illumination is required. In these circumstances, it’s worth considering an LED bulb with a lower lumen output such as 1000 lumens which will still provide more than enough brightness for most tasks.
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 1000 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 of warm white.
When looking for a LED light source with a lumen output of 1800, you can expect something that is very bright and intense. It’s perfect for use in areas where a lot of illumination is needed such as workshop or garage spaces, or if you are looking for a powerful LED security light.
The light emitted from a 1800 lumen LED will be very bright, and the beam of light will be able to travel a long distance from a tightly directional source such as a flashlight. It will shine approximately 500ft or 150m, depending on the width of beam angle the light has.
For an average sized bedroom, a 1800 lumen LED is a good light output for the main ceiling light. It will provide enough brightness for general activities such as reading, cleaning and dressing.
However, be aware that bedrooms are best lit from multiple smaller sources of light rather than a single bright central main ceiling light.

An 1800 lumen headlamp is very bright for outdoor activities such as camping and hiking, with a penetrating throw of light it will suit most applications and be a real asset.
When you look for a camping lantern the brightness of 1800 lumens is good, achieving the balance of enough light to illuminate your surroundings from a single source of light.
An 1800 lumen security light is bright and will easily illuminate the spaces surrounding your property. It’s a good option for lighting up where you need it most, however it is among the lower brightness levels for an LED security floodlight.
An 1800 lumen LED bulb is approximately equivalent to a 125-watt incandescent light bulb.
The brightness of a 1800 lumen LED bulb is very bright and requires a good level of heat management to ensure longevity and consistent color.
A 1800 lumen LED strip is a very bright light source, and will be perfect for use in areas where a lot of illumination is required.
The brightness of a 1800 lumen LED strip is perfect for use in areas such as under-cabinet lighting, in garages or workshops, or for accent lighting.
For task lighting, 1800 lumen LED is a good option as it will provide enough brightness to complete most tasks without being too harsh on the eyes.
In a task lighting application, 1800 lumen LED will provide enough light for most activities such as reading, working on a computer or crafting.
An 1800 lumen LED downlight is very bright for residential applications and suitable for higher ceilings over 4m otherwise the light will be too intense and create glare.
An 1800 lumen fog headlight is a good option if you are looking for a powerful and bright light source. This brightness will penetrate the fog and provide good visibility in poor weather conditions.
Although wattages are often used when describing how bright a bulb is, lumens are a better measurement. 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.
Useful comparative measurements often asked:
Lux can only be measured by knowing the distance and the area the lumens have to travel to.
1800 lumens is 1800 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 is colder and consequently seems brighter.
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 1800 lm would be less than 1800 candela with the candela only quantified if the angle of beam width is known.
One of the most common questions asked when comparing LED bulbs is how much brighter a 3000 lumen light source would be compared to 1800 lumens. The difference between these two will vary depending on whether you are using them for indoor or outdoor lighting. In general, however, it’s safe to assume that an additional 1000 lumen output from a 3000 lumen bulb will be very noticeable and perfect for use in high-intensity applications such as car repairs or during a power outage.
Comparing the key projector brightness measurement differences, where 1 ANSI lumen = 0.8 ISO lumens, we explain which one is more important.
