Frequently Asked Questions
My light seems faulty – what should I do?
The first thing you should do is perhaps change old batteries for new, full ones and check if these are making proper contact. If you use rechargeable batteries, you should check if these are charged.
If your light still isn’t working even with new or charged batteries, proceed to the next two steps:
When did you purchase your light?
- If the date of purchase is less than 24 months ago, please contact the retailer from whom you bought your light from. Your retailer will check if the problem is covered by the warranty.
- If the purchase date is more than 24 months ago, then please use the support form on our website and fill it out accurately. You will find it here.
If you press the switch on your torch or headlamp and it flashes 2-3 times and turns off straight away, you are in travel lock mode, depending on what model torch or headlamp you have, try holding the switch down for 5-7 seconds to unlock travel lock mode, you can repeat this to put your product back into travel lock mode and stop your products from accidentally getting bumped and turning on when not in use.
My new torch is heating up when left on the Constant Light function over a long period.
Is something wrong with it?
Our new range of headlamps and torches has been created with the technological advantage of over 20 years of LED lighting experience.
We have engineered the latest products in our range of headlamps and torches using the very best LED technology in the world. Through technological advancement, we have created a range of products with updates on our features including, Constant Light Technology, allowing your Ledlenser product to produce higher light output for an extended period.
When using your product’s High-Power Mode over a sustained period, you may experience that the product itself feels warmer to the touch and this temperature will remain as long as the light is in use. This is due to the product omitting a higher lumen output over an extended period. If you do not require the highest lumen output reduce to either mid-power or low-power and this will decrease the temperature being emitted.
This increase in temperate is completely normal and your product will not exceed a safe temperature and therefore will not burn your skin. We have developed Temperature Control Technology, to ensure that your LED light will not overheat internally or externally- Protecting the integrity of your Ledlenser product.
If the light still doesn’t work after cleaning and replacing your old batteries with new ones, you should contact your retailer if the purchase date is less than 24 months ago. Alternatively, you can use the support form on our website. You will find it here.
Please select the field “Support: Warranty/Repairs for End Customers” in the form and fill it out completely. Our staff in support can then decide whether to send you the respective replacement part (battery magazine or end cap, depending on the model) based on the warranty/goodwill.
First of all, you should be aware that our lights are not designed to be directly shone into people’s eyes – this can cause damage to the eye.
So never directly shine our lights into your own or other people’s eyes!
The rays produced by the LEDs built into our lights go beyond the wavelength spectrum that our eyes recognize as light. In the spectrum of regular light sources, we have ultraviolet rays (UV) as well as infrared rays (IR). These invisible rays present, just like blue portions in visible light, a significant danger for our eyes if there is direct exposure.
Some models, e.g. lights in the M-Series, can be programmed. To program your light you will need the Quick User Guide or the Smart Instruction Card.
You will find this under the menu item “Service & Warranty” under Downloads. Here you can select your light and download the document as a PDF.
First of all, you should carefully remove the batteries from your light.
If your model has a battery compartment, you will most likely no longer be able to use this. If you would like to attempt to clean it, use penetrating or multifunction oil to clean the leaked battery fluid. You can find this oil at any hardware store.
In any case, you should always clean the inside of the light compartment. This can also be cleaned with the described agents and for example, a small, medium-to-hard wire brush.
The head of your light is comprised of two different parts. The purely cylindrical part with the reflector lens and the Speed Focus carriage tapers off into a tube. In some newer models, the cylindrical part is silver.
Unscrew the cylinder from the Speed Focus carriage in an anticlockwise direction.
Please note that you should NEVER TOUCH THE LED.
Remove the Speed Focus carriage from the light downward. Now you can properly clean all of the parts from the inside with a damp or dry cloth. You can treat the O-ring which can now be seen on the light compartment with silicon-free grease.
Then re-close the head of the light by again pulling up the Speed Focus carriage and screwing it back together with the cylindrical part. In all models with a Focus Lock function, you have to pay particular attention to one thing when pulling up the carriage. The grooves on the inside of the carriage have to slide exactly along the tracks that are intended for that purpose.
The head of your light is comprised of two different parts. The purely cylindrical part with the reflector lens and the Rapid Focus carriage tapers off into a tube. In some newer models, the cylindrical part is silver.
Unscrew the cylinder from the Rapid Focus carriage in an anticlockwise direction.
Please note that you should NEVER TOUCH THE LED.
Remove the Rapid Focus carriage from the light downward. Now you can properly clean all of the parts from the inside with a damp or dry cloth. You can treat the O-ring which can now be seen on the light compartment with silicon-free grease.
Then re-close the head of the light by again pulling up the Rapid Focus carriage and screwing it back together with the cylindrical part. In all models with a Focus Lock function, you have to pay particular attention to one thing when pulling up the carriage. The grooves on the inside of the carriage have to slide exactly along the tracks that are intended for that purpose.
This problem is normally due to low batteries. You can often solve it yourself.
The flickering/delay can be a sign that the batteries in use are getting too low to still be able to properly power the light.
Many of our models can also be powered by other energy sources – here is a list PDF
Some models have an external USB port built into the casing (H7.2 and H14.2). This port is a connector for the Ledlenser power bank (item number 7709), which provides additional power for your light.
Third-party products cannot be operated using this port.
No. The lifespan of our LEDs is up to 100,000 hours depending on the type.
However, after that, the LEDs do not by any means suddenly switch off. This is related to the definition of the lifespan of an LED. LEDs are microchips whose brightness slightly but continuously fades. Their lifespan is defined as the period after which the starting brightness has fallen to 50%.
The advantage of Ledlenser lights is that they can run for a considerably longer period. But this does mean that the brightness starts to fade after a while as the battery capacity goes down (generally not noticeable during use).
The batteries do, however, depending on how you use the light, regenerate somewhat after you switch the light off, and are more powerful the next time you turn it on. They will then start to go down again.
With a controlled light the brightness remains nearly constant throughout its battery life. However, as soon as the battery is used up, it goes out very fast. So that your light doesn’t unexpectedly go out on you, you should take this into account when using controlled lights.
Besides, the battery capacity is completely used up after only switching the light on or off a few times. Generally, after a controlled light goes out there is still a measurable residual charge which an uncontrolled light can still use. Therefore the battery life of an uncontrolled light is longer.
In some of our lights, such as the M7, you can choose between controlled and uncontrolled operating modes.
You have several lights from Ledlenser and the color of the light in the last one is slightly different from the others?
That is perfectly normal with LEDs. When they are made they are doped like computer chips and then coated with a conversion layer. This converts part of the blue light created by the chip into yellow light. The combination of the two colors is what creates white light. Like in any technical process there is a certain amount of variation. For LEDs, this is called binning.
This binning also pertains to the color of the light, so there are relatively large differences between different chips – even if the chip type is the same.
No. What appears to be a black rim when you look at it, is a rubber insert that holds the reflector lens in place.
The rubber must be in contact with the lens for it to be held securely in place. However, it does not impair the optical qualities of the light. The light does not escape here but is directed within the optical system by total internal reflection.
The time to change the batteries will depend on various factors: the requirements, your personal preferences, and also how long the light is still going to be used.
In some circumstances, it is advisable to take extra batteries with you and/or to put new batteries in before a long trip. As a general rule, batteries should be taken out if the light is not being used for a long time.
