Review: Loses charge after a few uses and will not charge up again - This is a lovely little light and I am very happy with it. Please bear in mind that there is a lock feature which can make it appear that the light is not charging properly. If this happens, you need to press and hold the on/off LED for about 5 seconds before using the light. It will flash from red to green, and then you can use it normally.
Review: Great quality bike light - I bought this light to accompany a much older LED light as 1 light was not sufficient to light my way down dark country lanes. This Olight is a decent quality light and really does give a nice beam so I can see where I am going! The only disappointment to me was the battery life. Maybe I was expecting too much, but after little more than 2*20 minute journeys, I got the red flashing warning symbol, where as my old light could go for several days before needing a recharge. Admittedly the old light is nowhere near as powerful so that is to be expected, but I was quite surprised. The only other thing was the fitting instructions which I thought were quite poor. What I did not appreciate is that there were different attachments for other bike frames etc, but I worked out what to do in the end. For the money though, it is a very good light!

### ⭐⭐⭐⭐⭐ Loses charge after a few uses and will not charge up again
*by Y***G on 4 October 2025*

### ⭐⭐⭐⭐⭐ Great quality bike light
*by P***S on 22 November 2021*

I bought this light to accompany a much older LED light as 1 light was not sufficient to light my way down dark country lanes. This Olight is a decent quality light and really does give a nice beam so I can see where I am going! The only disappointment to me was the battery life.

### ⭐⭐⭐⭐⭐ Bright but short battery life
*by T***S on 22 January 2022*

Although this is a strew and bright light the battery life is not long enough for long commutes and if like me you own a road bike then none of the four straps will work as even the smallest one is too big. That said for the price it's a good light.
