Lumens are the unit every flashlight is sold on and the one most people have no feel for. A number like 1100 sits on the box with nothing to measure it against. This is an attempt to give it a scale.
What a lumen actually measures
A lumen measures total light leaving the torch, in every direction the optics send it. It says nothing about where that light goes. Two torches rated at the same 1100 lumens can behave completely differently: one throws a tight column a long way down a field, the other spreads a soft wall of light across a garden. Same lumens, different jobs.
The figure that describes reach is candela, or beam intensity, and it is usually quoted indirectly as beam distance in metres. Under the industry ANSI FL1 standard, beam distance is the point at which the light falling on a surface drops to 0.25 lux — roughly the illumination of a clear night under a full moon. It is a deliberately dim threshold. At the stated maximum distance you can make out that something is there; you are not reading by it.
So: lumens tell you how much light. Candela tells you how far. A specification with only one of the two is telling you half the story.
1100 lumens, next to things you already know
Rough, real-world comparisons rather than laboratory figures:
- A phone torch — typically somewhere between 20 and 100 lumens, from a tiny LED with no reflector behind it. It lights your hands and the first couple of metres. It is a candle you can put in your pocket.
- A household LED bulb — a bulb sold as a 60 W equivalent puts out around 800 lumens; a 100 W equivalent around 1600. So 1100 lumens is, very roughly, a bright ceiling bulb's worth of light — except a bulb throws it at the whole room and a torch throws almost all of it in one direction.
- A typical head torch — most sit between 200 and 500 lumens on their high setting.
- A car headlight — a halogen low beam is in the region of 1000 to 1500 lumens per bulb. This is the comparison worth holding on to: 1100 lumens in the hand is in the same territory as one headlight, aimed wherever you point it.
That last comparison is the useful one. It also explains why a torch at this output is uncomfortable indoors. Pointed at a white wall two metres away it is genuinely too much light. Bright torches are built for outside.
Why more lumens is not automatically better
Three things get worse as the number goes up.
Runtime
Light costs energy. A cell that runs a torch for many hours at a low setting will run it for a fraction of that at maximum. This is why usable torches have modes: the top setting is for the moment you need it, not for the walk home. If a torch has only one brightness, the battery figure on the box is the only one you will ever get.
Heat
An LED converts a good deal of its power into heat, and that heat has to leave through the body. A small metal torch at full output gets warm in the hand within a few minutes. Many torches step themselves down automatically to protect the emitter, which is why a torch can seem dimmer after five minutes than it did at switch-on.
Your own night vision
The most overlooked cost. Human eyes take roughly twenty to thirty minutes to adapt fully to darkness and lose that adaptation in a second of bright light. Walking a path on maximum, you see a bright cone and total blackness either side of it, and you have destroyed the low-light sensitivity that would have let you see the rest. Much of the time a low setting shows you more of your surroundings than a high one.
This is the argument for a red mode. Red light interferes far less with dark adaptation, which is why it turns up on map lights, observatories and aircraft instrument panels.
What to look for instead of a single number
- A low mode you would actually use. Most real use is close-range: a lock, a bag, a fuse box, a dog lead. A torch whose lowest setting is still dazzling is a torch you will squint through.
- A stated beam distance. If a maker publishes lumens but no distance, the beam is probably flood-heavy. That may be exactly what you want — just know which you are buying.
- How you change modes. A single button that cycles through nine settings means sitting through eight of them to reach the ninth. Two switches, or a press-and-hold shortcut, gets you there directly.
- How you know the battery state. A torch that gives no warning before it dies is a torch you cannot rely on. A percentage readout is worth more than a hundred extra lumens.
Where the RavenTorch sits
The RavenTorch EDC flashlight is rated at 1100 lumens with a beam reaching 100–200 metres, and it is built around the points above rather than around the headline figure. Two main LEDs give a flood and a throw at once. A separate side panel handles close work, with white, red for night vision and UV for inspection. Two switches instead of one, so the main beam and the side panel are independent and neither is buried behind a cycle. A digital display reads the remaining charge as a percentage, so the battery is a fact rather than a guess. It charges over USB-C from the cable you already carry.
1100 lumens is a lot of light. Whether it is the right amount depends far more on what the torch does with it.
