I just tested this lamp hike on the night of 25 bumps; awesome! Long range, cone large enough to not have zoom function needed (btw do not!), very good resistution colors, the light is really white and alters the colors of the landscape! but all that power is abused, not really useful! besides she gene other hikers as it surpasses all other lamps! I was leading greenhouse and I lit the way for 12 people !!!! So for hiking, I recommend a two rather see three T6 LED, enough! you'll also greater autonomy; that said, it's not bad! 2 hours continuously! chaufffe the lamp a little but nothing alarming! recharging is done in an hour, though! Attention also has fixation in front; The maximum head circumference of 55cm matches! European adute revolves around 57, so ca too tight and not failed, sore skull! must be modified or adapted greenhouse another head; Me, I advise for a Velcro attached to the ceitnure or the backpack! plus ca avoids dazzling other! especially careful not watch led in operation, risk of retinal burn !!!! voila, very good product, nice finish, all accessories are sensible, well thought out and fixing simple but effective bike (I tried on 24 ATV Cergy)!
