You may be wondering that a headlamp that has 160 lumens is far better that the one which has only 80 lumens.. Well, it turns out that these numbers could not really be accurate or could be deceptive. It is important to mention that in headlamps, lumens output is estimated with a gadget known as integrated sphere. The can estimate the aggregate sum of light put out by the bulbs or LEDs. Yet, this doesn’t really give an accurate measurement of how the lights falloff would be.
It is known that sometimes, the overall light emission of a cheaper headlamp which has a very low lumen number would be much better and stronger that an expensive and far superior headlamp that has a higher lumen count.
Instead of focusing on the lumen number, what is more important is to focus on the light beam quality and distance. To understand this further, we can look at the two different modes that are features in most headlamps.
- Floodlight: The floodlight mode is ideal for making closer objects more clearly visible, the light is general and spreads across the space evenly. If you are spending little on your headlamp purchase, you may end up with one that only has this single standard mode.
- Spotlight: As the name suggests, it’s considerably more engaged light and that is focused in a single direction or ‘spot’. The uses of this mode although limited and specific, could be real game changer.
Both these lighting modes will have its very own application when you are out in the field and pretty much similar lumens output. But as a rule of thumb, you should be looking for better features and specification in general and not so much the price. This is an investment that you would be able to use and benefit from for a long time to come, so invest wisely.
