TL900 TORCH - 300 lm: instructions, repairs, maintenance advice


Have you bought a TL900 torch? Do you have a question or have you encountered a problem with your model? Don't panic, we are here to help you!

The information contained in this sheet applies to our TL900 torches.


What is reserve mode

When the battery reaches a very low level, the lamp automatically lowers the power so that it keeps working for another hour at 50 lm.

How do I know the charge level of my battery?

An indicator light on the top of the headlamp lets you know the battery's level of charge within seconds of switching it on.

> Green = between 50% and 100%
> Red = less than 30%

What is red mode?

This mode allows you to navigate or get around in a very short range with a less dazzling colour for those who are nearby. This light also makes it possible to lower nocturnal acuity (ability of the eye to see in the dark).
The red mode is therefore popular in refuges, in tents or in groups, but also for star lovers.

Looking after my torch

How do I store away my headlamp correctly?

It is important to store the lamp in a place protected from direct sunlight and humidity. During long-term storage, remember to remove and fully recharge the battery (every 6 months).

How do I clean my headlamp?

The headband is removable and washable. You can wash it with soap and water. 
You can also clean it using a humid cloth.

Can you replace a LED?

Unlike conventional light bulbs that could be easily unplugged, LED technology does not allow them to be replaced because they are soldered to the electronic board. The LEDs we use, on the other hand, have a very long lifespan which ensures you use them for several years without any worries.

What happens to the lighting products returned to the store?

Headlamps are subject to the provisions for the recycling of electrical and electronic products (e-waste). At the end of its life, you can bring your headlamp back and deposit it in the recycling bins at the entrance to our DECATHLON stores.

Specifications of my TL900 torch

What are lumens (lm)?

Unlike watts, which express the energy consumption of an electrical device, lumens correspond to the quantity of light actually emitted by the lamp.
This measurement is carried out by placing the lamp in an enclosure fitted with sensors and measuring the light emitted in all directions around the lamp.
PLEASE NOTE! At equal power, all the lamps will not have the same lighting range because it will depend on how concentrated the beam at the exit of the lamp is (with a lens or a diffuser).
The narrower the beam, the farther the lamp will illuminate.
The wider the beam, the better the lamp will illuminate the sides evenly, but to the detriment of the range.

What are lux?

If the lumens correspond to the light emitted by the lamp in all directions, the lux corresponds to the light received locally at a point illuminated by the lamp. This illuminance unit therefore makes it possible to measure the lighting distance of each lamp.

How is the maximum power of a lamp measured?

The maximum power of a lamp is measured in the first 2 minutes of lighting up, new batteries (or fully recharged).
On some models offering temporary modes (Boost modes), it corresponds to the power of this mode.

How is the range of a light calculated?

According to the ANSI-FL1 standard, all the lighting ranges of Decathlon products correspond to the distance at which the lamp can illuminate at 0.25 Lux.
This value corresponds to the illumination received by the moon under ideal conditions (clear weather, full moon).

How is the autonomy of the lamp calculated?

For each lighting mode, the autonomy corresponds to the time during which the lamp is capable of supplying 10% of the maximum power of this mode.

Powering and recharging my TL900 torch

What type of USB port does this model have?

The power adaptors for our TL900 torches (ref. 8588393) are micro-USB compatible. You can therefore use your own cable to recharge them if it is of the Micro-USB type.

What type of charger can I use to charge my headlamp?

TL900 torches can be charged via USB. You can therefore connect them to any charger (car, sector, solar panel, computer) as long as this charger is USB compatible.

End of product’s lifespan

Your headlamp has just broken and it is not possible to repair it. You mustn’t just throw it away.
You must recycle your headlamp and dispose of it at an e-waste collection centre.
