The ad said it was 500 lumens, but the paperwork in the flashlight says 300 lumens. Other than that, it is a really nice flashlight-headlamp, mostly made of metal, with a power dimmer and a focus adjustment. Solid feel, came with batteries, which I did not expect. 300 lumens is actually quite bright, so it suits my use (nighttime mountain bike headlight). I would recommend this to a friend since it is such a good value.
My first product was DOA. The replacement is good. It is very bright and can focus the light beam using the focus lever. On the battery case, there is a dial to adjust the light intensity. For anybody who needs such versatility on a headlight, this is an excellent choice.
All functions on the head light worked. The dimming, flashing, on off. It is comfortable. It came really slow in mail. Got hung up at the post office. 3 AAA batteries easy to install and soft rubber cover easy to get on and off and is comfortable to wear.
This headlight is up to 500 lumen with CREE Q5 LED, 2 switch modes for your choice. With the super high-brightness, it is a perfect partner for self safety, hunting, cycling, climbing, camping and outdoor activity, etc.
