Question: Is this comfortable?  I need it for reading for long periods of time.  I'm a small, older woman who wants bright light!
Document: The headlight fits well, is easy to adjust, and comfortable to wear. The main concern is brightness. I use this type of light for emergencies where I need a lot of light and this is not as bright as my older light. That said, it's also only 1/3 of the price. For the money this is a good general purpose light for camping, to keep around for hiking, and nature activities where you don't want or need a bright long range light.
The pool of light for reading is evenly bright, no lens shadows.What I hadn't even paid attention to was the third setting, a strobe. When the whether warms here in the Northeast and I'm out riding my bike, I will definitely have this on flashing away to alert cars to my presence.Durability, I can't speak to. But it seems well made. And it's comfortable to wear.
This light is extremely bright and can be focused quickly to change from up close projects to long range ones. The straps fit and are comfortable on the head. The weight of the light is a little more than the competitors, but the brightness is much greater. The red band around the lens is annoying unless a cap is worn or it is covered with a strip of electrical tape. The light does everything it is advertised to do and I recommend it if you need to light IT up.
Recieved the item on time. Extremely bright. Helps me a lot on my job. Highly recomended. Headband is very comfortable for long wear.
I have two other headlamps that I bought at REI for more than I paid for this one, and this one is hands down the best of the three. It's lightweight, remarkably bright (but you can dim it), versatile and comfortable. I use it around the house when I need a flashlight but the project I'm working on requires two hands. I've jogged with it comfortably. I have a friend who owns one and he bikes with it. I'm entirely satisfied with it.
I got this for my husband for Christmas. Unfortunately, he got another one a few days before Christmas, so I thought.....ohhh he's gonna want to return it. Absolutely NOT!!! He loved this product much better and uses it to walk the dog almost every night. Long lasting battery and comfortable on the head. He likes the dim to save the battery when you don't need intense light for working on something, i.e. walking along the road.
I was blown away by the power of this light.I did not notice any glare coming down on my face like I experienced with a similar product from energizer.Light tilts easily to put light where you need it.The light can be focused so tight that I'm pretty sure you could cook ants with it if it weren't an LED light.straps are comfortable and keep the light stuck to your head or hat.needs 3 AAA batteriesI didn't get this wet in the rain, but it seems fairly water resistant.
2 caveats: 1, I've only had this a few days; 2 I have one small gripe: the band that goes over the head could be adjustable to a bit longer for those of us with big heads and lots of hair.Other than that:  This fits the bill. I bought it for reading in bed without my bright light that kept my wife awake; and for walking the dog. Two different applications, but well within the flexibility of this product.
I'm a helicopter pilot and have to preflight my aircraft at 0530 in the dark. This little handy headlamp is bright and can be used as a diffuse beam, or a focused beam of light which is great for checking small aircraft parts. I'm very happy with this product and will buy another come hunting season.
This headlamp is advertised as the &#34;BRIGHTEST & MOST COMFORTABLE HEADLAMP ON AMAZON! !&#34;  It is not. Although when zoomed in to focus the light on a small area the lamp is very bright it leaves much to be desired when not zoomed in. It will not light up an area or a room like the broken Streamlight headlamp that I am replacing. The false advertising is a disappointment! It is also tight and not so comfortable on my rather large head.
Answer: yes
