Ledlenser FAQ: Questions and answers about our flashlights & headlamps

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?

1. If the date of purchase is less than 24 months ago, please contact the retailer whom you bought your light from. Your retailer will check if the problem is covered by the warranty.
2. 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.

My flashlight only flashes when I switch it on. What could be the reason for this?

You have probably activated the transport lock without realizing it. Many of our lamps are equipped with this function. It is designed to prevent the batteries in the torch from being used up if the torch is accidentally switched on in a bag or case, for example. The transport lock can be activated and deactivated using a key combination that varies depending on the model. As a rule, you need to press and hold a specific button for a few seconds. You can find out which button this is for your lamp in the operating instructions.

You can find more information on this topic in our guide:

My Ledlenser lamp only flashes

Some of my flashlight's functions no longer work - what should I do?

ESome 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.

What do I do if the batteries in my light have leaked?

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 a 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 which tapers off into a tube. In some newer models the cylindrical part is silver.
• Unscrew the cylinder from the Speed Focus carriage in 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.

With fading luminosity, the lights starts blinking at regular intervals - what does that mean?

Tip: Treat the battery compartment on a regular basis with contact spray to avoid leakage problems. You should remove your batteries from your light if you do not use it for a long time.

If the light still doesn’t work after cleaning and replacing your old batteries for 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.

Is it harmful to shine a light directly in someone's eyes?

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.

My flashlight is diffcult to focus - what should I do?

1. The head of your light is comprised of two different parts. The purely cylindrical part with the reflector lens and the Rapid Focus carriage which tapers off into a tube. In some newer models the cylindrical part is silver.
2. Unscrew the cylinder from the Rapid Focus carriage in anticlockwise direction.
3. Please note that you should NEVER TOUCH THE LED.
4. 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.
5. 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.

My light flickers or there is a delay when I switch it on - what is the problem?

1. This problem is normally due to low batteries. You can often solve it yourself.
2. 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.

Can I run my light on alternative energy sources?

Many of our models can also be powered by other energy sources.

Do LEDs suddenly burn out like bulbs?

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 of time after which the starting brightness has fallen to 50%.

Why is the switching sequence of my P7/P14 different than what is stated in the user manual?

It’s possible that the actual switching sequence does not match what is in the user manual. It does not mean the light is defective, but rather that the user manual is an “old one” which was enclosed with your light by mistake.

The switching sequence has been changed due to the experiences and wishes of our customers. For the P7 with S/N from: 91.646 and for the P14 with S/N from: 22.366.

Former switching sequence:

1. Tast-Modus: 130%
2. Eco-Modus: 15%
3. Power-Modus: 100%

What are the differences between the Core, Work and Signature models from Ledlenser?

The Core, Work and Signature models are aimed at different target groups and are optimized for the respective application. The Core models form the basis. They are equipped with the typical Ledlenser functions and technologies.

The Work models are more robust and designed for use in trade and industry. However, they are also suitable for any private user who requires particularly robust lamps. In addition, extensive accessories are usually included in the scope of delivery.

The Signature models are the premium lamps in each series. Like the Work models, they are also based on the Core model, but have more power, such as a higher luminous flux. In addition, we have placed even more emphasis on high-quality materials and an even more appealing design for these models.

You can find more information on this in our guide:

Differences between Core, Work & Signature models

Why are lights in Ledlenser different colors?

You have several lights from Ledlenser and the color of the light in the last one is slightly different to 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.

There is a visible black rim around the reflector lens. Is this a sign of poor workmanship?

No. What appears to be a black rim when you look at it, is a rubber insert which 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.

When should you change the light's batteries?

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.
