![]() The reason I want to look at these two tactical flashlights is because the XT11GT can seem brighter than the XT11X even though the XT11X has a higher lumen count. I’ve put another example below comparing two Klarus flashlights, one is the Klarus XT11GT that delivers 2000 lumens and the other is the Klarus XT11X. For this reason, some LED flashlights can appear brighter than others even if they have a lower lumen output. The one with the focused hotspot has a higher candela rating than the one without. As you can see above, while they both have a very similar output, their candela count is quite different. The image on the left is the Klarus G20 3000 lumen floodlight and the one on the right is the Klarus XT11X 3200 lumen tactical flashlight. I’ve put a picture here of two different beams from two different flashlights, both with a similar lumen output. As you can see, the G20’s beam is so wide that I couldn’t fit it entirely in the image! The light is so dispersed and the hotspot smoothly combines with the spill which is why the G20 has a lower candela rating. ![]() By looking at the candlepower, you’ll get a better idea of what kind of beam you’re looking at.īoth of these flashlights were taken at the same distance from the wall. The best way to remember it in my opinion is that lumens measure the total output of light while candelas measure the intensity of the hotspot on the LED flashlight. So the major difference between the two is exactly what they measure. What’s the Difference Between Lumens and Candelas? There’s also a formula supposedly that gives you the general amount of lumens one candela is, but I’ve seen different answers so I wouldn’t rely on it. Nevertheless, it gives you a good idea of how much light one candela is. There’s more to it then that as the single candle to which it’s measured has certain dimensions. Fun fact: one candela is approximately the same amount of light from a single candle. So a flood light and a throw light could have the same lumen count, but the throw light would have a higher candela count because most of the light emitted is focused in the hot spot.Ĭandela is also known as candlepower which is a word you may have seen before if you’ve searched for reviews of the best tactical flashlights or browsed flashlight forums. In other words, it measures the amount of light that is focused in a single direction which, for an LED flashlight, would be the hotspot. This means that the lumen count does not take into consideration beam pattern at all.Īs I said before, candelas also measure light, but they measure the focused part of the beam where most of the light shines through. Lumens measure the total visible light that a device, such as an LED flashlight, emits. Both lumens and candelas are a measurement of light, but they measure different aspects of the light. So let’s start with lumens because they’re the most common feature everyone talks about. ![]()
