1000 lumen: Determining the Number of Lumens You Need for Your Bulb

Have you ever asked yourself why some lights are very bright and others are not? Here we have the answer to this. The quality of light on a lighting device results from several factors such as the number of lumens the device has, run time, and beam distance. Therefore, in this article, we will look at several factors that influence the quality of lighting. Ensure you read this article till the end to equip yourself with the necessary tips.  

What is a lumen?

 

lumen
 

A lumen is a measure of the full amount of light, mostly known as an angle or beam that emits from the light source. Besides, the amount of lumens from the source is due to its range, as shown in the luminosity function.  

1000 lumen

 

1000 lumen
 

A 1000 lumen is the rating on a lighting device. Moreover, a 1000 lumens flashlight with bright light can help explore large areas, hunt, or look for something in a shipyard. Additionally, you can use the light for leisure purposes on a large premise or even in rescue operations. A 1000 lumen is very powerful.

Lights with this amount of rating produce more light; hence they are expensive than their counterparts with small ratings. However, it would be best if you were very keen when using this light since direct lighting can damage your eyes. Flashlights with 1000 lumens and above are common in military service.  

1500 lumen

 

1500 lumen LED Flashlight comes with an adjustable focus for short and long-range lighting. This flashlight can illuminate for up to 200 meters. Additionally, this product comes with a high grip barrel made of aluminum that you can use with gloves. Moreover, this flashlight can run for up to 10 hours. This means you need few battery changes.  

300 lumen led

 

A 300 lumen LED flashlight is a lighting device suitable for fishing, sailing, and carrying tactical tasks. Additionally, if you are looking for a flashlight to use for the home, workplace, or even in your shop, then a 300 lumen LED bulb is the best match. Unfortunately, these kinds of flashlights are powered by alkaline batteries making it a drawback for this product.  

500 lumen led

 

A 500 lumen LED flashlight is ideal for commercial and home use. Therefore, if you are looking for the best illumination, this is the best fit. Additionally, this product is somehow energy efficient and can shine the light a long distance. You can also use this flashlight for hunting, fishing, camping, and traversing into deep caves.

Moreover, lighting devices with this type of rating use Li-ion batteries that are rechargeable. Also, the batteries allow you to have full power to an LED bulb.  

How to determine the number of Lumens You will Need

 

How to determine the number of Lumens you will need
 

Currently, you can measure energy-saving LED flashlights and bulbs in lumens. Therefore, the number of lumens shows how clear the bulb is. When you compare lumens to the earlier measure of watts, lumens are more accurate.

Basically, to determine the number of lumens, you require for your room, first get your room area to get square footage by multiplying its length and width. For instance, a room measuring ten by 1o feet has an area of 100 square feet.

After that, you should work out how many foot candles (another name for lumens) you require per square foot. Nevertheless, this varies depending on your specific room and its use.

Therefore, the number of lumens for a living room is different from that of a shop.

To be precise, a bedroom will need around 15-20 lumens per square foot, and a kitchen or a washroom may require about 75-80 lumens per square foot. Therefore, from our example above, a room with 100 square feet will require around 1,200 – 2,000 lumens. However, this method gives you just a hint of the basic level of light you need in a room.  

Converting Lumens to Watts

 

Energy-efficient bulbs have a higher number of lumens per watt than other types of bulbs. Mathematically, the power in watts, P is equivalent to the luminous flux ΦV in lumens, divided by the lumens per watt η,(lm/W).

P (W) = ΦV (lm) / η (lm/W)

The table below shows a better conversion of Lumens to watts. Therefore, you can use it to get the correct rating of a bulb to your room.  

A table showing conversion of lumens to watts

 

Lumens Incandescent light bulb(watts) Fluorescent / LED(watts)
300 lm 20 W 5 W
500 lm 33 W 8 W
1000 lm 67 W 17 W
1500 lm 100 W 25 W
 

FAQs:

 

Are 1000 Lumens LED Flashlight too Bright?

 

Yes. A 100 lumen LED flashlight is very bright. This product is powerful enough to illuminate a distance of about 200 meters, depending on the reflector design and the lens. Therefore, this kind of flashlight offers you an opportunity to view objects at a far distance.  

How Strong is 1500 Lumen?

 

As we mentioned earlier, the number of lumens determines your bulb's brightness, hence its strength. For instance, fewer lumens means the light is dimmer, while more lumens means the bulb will produce a more bright light. Therefore, a 1500 lumen flashlight is more solid and bright than bulbs with less number of lumens.  

How far Does a 1500 Lumen Flashlight Shine

 

Since a 1500 lumen flashlight is a strong and powerful type of lighting, it can illuminate a distance of about 250 meters and more. This will help you observe objects at a far distance,  

What is the Temperature of 300 Lumens led

 

The energy used by a 300 lumen led flashlight produces about 15% heat, 80% IR and only 5% light. In comparison, a standard LED bulb can produce 85% heat and 15% light. Therefore, it is wise to do away with this heat by the use of efficient heat management.  

How long will 300 lumens led last on

 

Manufacturers calculate the lifetime of an LED flashlight in terms of hours. Moreover, all kinds of lamps have output light that fades slowly over time. Besides, LED flashlights do not fade; hence they can perform for about 25,000 hours. Therefore, a 300 lumen LED flashlight can last for 25,000 hours.  

Conclusion

 

A 1500 lumen LED flashlight is a very bright and powerful flashlight that is suitable for most tasks. Nevertheless, the number of lumens you need in your room depends on the application. Additionally, the design of the lens and reflector is another essential feature to consider. This feature has a significant impact on the usage of lumens. When looking for a bright flashlight, it would be better to consider other aspects such as runtime, beam distance, and bulb type. All these factors determine how bright the LED flashlight is. Therefore, having gone through our article, I believe you now have all the knowledge you may need when it comes to lumen on a flashlight.
