My new favourite Headlamp

The 18 is a very well made and versatile Headlamp, the new headband design is great and sturdy. It offers bright floody light combined with the red light witch won't attract insects. Also the new 6400 mAh battery offers long runtime. Can really recommend this product.

Great!, Excellent!

This headlamp is excellent. It is comfortable and versatile, with great brightness and overall performance. I especially like the USB charging port cover. It’s great that, instead of a small plastic/rubber cover, it now has a magnetic closure. That’s a really nice improvement. One small suggestion: the magnet at the end of the headlamp could be stronger. Keep up the great work, ACEBEAM! My compliments to the development and design team. I can highly recommend this headlamp.
