![]() This amount of lumens is technically enough for urban and suburban use. An average 100 lumens flashlight is able to provider 5 -10 hours runtime using 2x AA battery. A 2x AA battery 10 lumens flashlight can give you a full day run time.ġ00 Lumens: Standard for now a days average flashlight. This amount of brightness also will give you enough light for emergency situations like assisting in blackout or while finding something lost in store. But 10 lumens flashlight is well enough for your hiking, camping, backpacking activities. Surprised!! Because it is very hard to compare as the brightness of candle is not focused through beam like flashlight. Normally, 2x AA battery flashlight with 1 lumen will give you few days run time.ġ0-30 lumens: this amount of lumens produces brightness like a candle. But this is well enough for reading purpose (consideration: the book should be 1 feet away where the beam spot is smaller and brighter). Interesting fact is you will find this 1 lumen useful if you are in pitch black darkness. If the beam is wider, the brightness of the light will be dimmer. But this consideration is depends on the flashlight beam’s wide. So, lets discuss how many lumens do I need for a flashlight? Please be informed that the below description is solely my own subjective judgment.ġ Lumen: Generally 1 lumen is considered as 10 times brighter than the moonlight. But for the advancement of LED light technology, in 2016 more than 1000 lumens tactical flashlights are already available in the market. If we look back few years ago, In 2005, 100 lumens was referred as the suitable for tactical flashlight which were commonly used by the law enforcement sector. Even if you like hiking, trekking, hunting, camping or walking at night then you always must carry a suitable flashlight for you and you need to ask yourself “How Many Lumens Do I Need for a Flashlight?” before you start your adventure.

Yes, it’s the flashlight which can help you to see through the dark night. Because you will not able to see what’s in front of you. Without any support you will feel like a blind. To be really sure whether the desired illuminance is achieved with the installed luminaires, it can be checked with a lux meter at the appropriate distance from the light source.Guess you are walking on the street in a pitch black dark night. The online calculator will help you to find a reference point for your lighting design. Now you know the correlation between lux and lumens in connection with distance and angle. In order to ensure homogeneous lighting with a corresponding lux value, a professional light planning should be involved. The positions of the individual lights are chosen in a way that the light cones overlap. So the illuminance in the light circle is not homogeneous.įor the complete illumination of rooms or specific areas with a minimum illumination intensity, in most cases several LED luminaires are used. ![]() Especially in the peripheral areas, the luminous intensity usually decreases. When using a single light source, it should be noted that the light distribution of many LED spotlights does not always have to be uniform within the beam angle. After a click on the Calculate button you will see the size of the illuminated area and the lux value. Select Lumen to Lux in the calculator and enter 470 as the lumen value, 110 as the beam angle and 6.5 for the distance. ![]() You want to find out how much lux the table is illuminated with. Example: A spotlight with a beam angle of 110° and a light output of 470 lumens is mounted at a height of 6.5 ft above a table.
