HL900 V3 hybrid headlamp: instructions, repair, maintenance

When the battery reaches a very low level, the lamp automatically lowers the power to allow you to move for another 1 hour at 25 lm.

To avoid it turning on in your bag by mistake, the lamp can be locked by pressing the two buttons for 3 seconds. A red flash confirms that the lamp is locked. Do the same to unlock it.

An indicator light present under the case lets you know the battery charge status in the first seconds of switching on the headlamp.

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

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.

Maximum mode lets you find your way off-trail, it’s a lighting boost of 600 lm for 1 minute which then returns to normal at 200 lm to preserve the product’s battery life.

Hiking and trekking lamps are designed to be compact and provide light during low-speed walking.
To achieve this, the HL900 is designed as a single forehead-worn module with a wide illumination beam in the early power modes then progressively narrower on higher power modes.
The first mode of our lamps is always a red light, then the other modes gradually increase the power until the strongest mode.
The double button system + and - allows to navigate between the modes without having to turn off the lamp.

Trail running lamps must be able to guarantee powerful lighting during rapid movements on all types of terrain.
They must also offer perfect stability on the head, hence the offset of the battery at the back of the skull.
Red mode is rarely present on this type of model.

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).

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

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.

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.

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.

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.

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.

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).

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.

The power socket of our HL900 USB V3 hybrid headlamps (ref. 8754082, 8754084, 8600660) is standard USB type C. So you can use your own cable to charge them if it's USB-C type.

HL900 USB V3 headlamps are USB-rechargeable. You can therefore connect them to any charger (car, sector, solar panel, computer) as long as this charger is USB compatible.

When the USB battery is empty and if you don't have access to a USB charger, it is still possible to use this adapter by placing 3 AAA size batteries (alkaline or rechargeable) in it.
Please note, in this case the battery indicator is no longer active and does not allow you to follow the discharge status of the lamp.
