• LED headlamps have changed the safety profile of outdoors activities and they are generally light, powerful and with good battery life of around 15hrs on a charge
• aim for:
• a beam distance of at least 80m (beam distance depends on the optical lens system which concentrates the light into a beam and the maximum output)
• a maximum output of at least 200-300 lumens/m
  • 10-25 lumens for reading
  • 25-150 lumens is generally all that is needed for around the house, for hiking, backpacking, and camping
  • aim for 200+ if you need a navigational aid in complete darkness
  • aim for 250+ if you’ll be traveling at higher speeds, such as a night trail run or mountain bike ride
• beam needs to be able to have a wide angle flood light for when working in close spaces
