BioLite HeadLamp 425 review: The best astronomy headlamp?

The BioLite HeadLamp 425, for our money, is one of the best headlamps you can buy. If you’ve seen our best headlamps for astrophotography and low light scenes buying guide previously, you’ll have seen the BioLite 330 on the list. Well, the BioLite HeadLamp 425 is its younger sibling, released at the end of September 2022.

BioLite actually had a complete refresh of their award-winning rechargeable headlamps, with three new models on the market: the HeadLamp 325, the HeadLamp 425 and the HeadLamp 800 PRO.
