This thing is bright. I use it every day for night fishing in the rain and my wife uses it for her job. You need to use the lock function if you are storing this thing in a backpack or bag. Once, my wife put it in her bag unlocked and the intensity of the light started to singe the backpack interior and it started smoking because the light was pressed up against some fabric and it started to burn.

Being an avid runner who typically run 10 miles per day (about half on the road and the other on various trails around the neighborhood) in SoCal, the recent heatwave got me thinking that I have to run at night to avoid driving myself to utter exhaustion. So, I did some research in running magazines and sites and the BioLite head lamps consistently appeared as being a good option. I decided to get the HeadLamp 200 for road running and the HeadLamp 750 for the trails and they are both working out really great. I know I'll put these to good use as well during the winter when the days are much shorter.

Running the trails at night is definitely a challenge and I know I needed a powerful head lamp but it couldn't be too heavy or bulky to affect such a demanding physical activity. It was a little spooky at first running into pitch black darkness of the mountain trails but I got used to it pretty fast after a few runs and it's actually very fun. The HeadLamp 750 is very powerful and provides plenty of light for near vicinity as well as further ahead so I can see what's ahead up to around 50 yards clearly. I do have to look up and down regularly to make sure I get good footing as well as seeing what's ahead, so that's the challenging part of running at night but that's still better than running in 90+ degree heat!

The 750 is twice as heavy as the 200 but the weight is evenly distributed between the lamp and the battery pack in the back and is fairly comfortable and stays well put even during fast and twisting runs through the trails. I'm very happy with it but I also have the Petzl Swift RL coming and will see how that compares to the BioLite 750. I'm hooked on night running now as there's an eerie calmness to it that one just can't get with "normal" day running. Not having to run about the sun setting early during the winter will be nice too. I should have thought about head lamps earlier. It was this dreadful heatwave that prompted me to look into a way to keep running. It's still hot during the nights with the temperatures in the low-80's but it's certainly heckuva lot better than running in the sun in the 90's. I highly recommend the BioLite head lamps to avid runners who need the flexibility in their schedules to be able to run during the night or very early morning hours.

Did lots of research on which to buy. This is the one that won. Love the quality and ease of use, including the battery pack in the back for great balance.

Excellent for all sorts of outdoor activities and projects!

The media could not be loaded. I'm an insulation Technician so I'm always in attics and basements. Went through so many headlamps from Home Depot and I noticed they died so quickly. Most headlamps will claim to be the lumens but it will only maintain the max lumens for 30 seconds to a minute. Forever mode is awesome. I'll attach a video. And since the weight is evenly distributed it feels lighter then all the headlamps I own.
