If your LUUMEN isn't working correctly, you can check the following which may solve your issue -
- Check the batteries are not dead and are inserted correctly, including the battery sleeve (See replacing batteries)
- Check for any debris inside the body of the flashlight. Even a small particle can cause connection issues, give it a clean with a cotton bud and blow out the body
- If your LUUMEN has suffered a drop or the top screwed on with too much force, the metal connection tab may have been bent back slightly. To resolve this remove the head of your LUUMEN and you will see a metal tab. Gently pull this back outwards and screw the head back on
If none of the above solve your issue, please use the contact page and we will get back to you as soon as possible
