Head Torch sub £50

[Wise]

Just using throw it's quoted as 300 lumen.

I'm finding I only get 4 hours at light setting 3 on the throw side rather than the quoted 8 hours.

If the actual (rather than the claimed) output is 350 lumens, then getting 4 hours out of a 3000mWh battery would imply an LED that gave you about 135 lumens/watt, which is about right.

Some useful info:

Sofirn HS20 Review (2700 Lumens, High CRI, USB-C)

It’s been a little while since I took a look at a new headlamp, well that ends today with the Sofirn HS20, a dual emitter headlamp with onboard USB-C charging and a really simple, yet effective interface. Thanks to Sofirn for sending this to me to look at and tell you about. I have been using it...

I've got a Sofirn HS20, I really like it apart from the battery life. I'm finding I only get 4 hours at light setting 3 on the throw side rather than the quoted 8 hours.

i use it on the lowest setting which is roughly equivalent to second lowest on a fenix hm70r which is what i always cave on (more than enough light for nearly everything) and I find I get 8-10 hours consistently with that
