Great head light! 1200 lumens
358538
I would like to start out with: I love this head light! I have been through possibly 10 of the energizer brand head lights this year. They are nowhere near as nice as this one. I am a contractor that works on foreclosed homes (therefore there is no electricity). Not being able to see well enough could cost me thousands of dollars if I miss some damages.

The 1200 lumens put out by this light make the entire room light up. You can focus the beam on a small area or expand it to cover the whole room. I like the different charging options (ac, dc or usb) as they make it very convenient since I am on the road a lot. I cant speak to the battery life yet since it hasn't died on me yet after using it for several days without charging.

The only negative that I have found so far is, after about an hour of use, the housing gets pretty hot to the touch. With the LED being 1200 lumens, i would say that is probably hard to avoid.

This is a great head light and I highly recommend it for work, camping, fishing, etc..

Awesome! headlamp. It comes in handy while doing work around the house and on the car. It adjusts to fit your head and provides a bright light.

This headlamp is so bright. It also features a strobe light on a different setting.

There are no lights in my attic and I often need to go up there for different reasons and I don't want to carry a flashlight. This makes it easy to see and have both hands available. The material is nice and stretchy so it fits well on my head.

I would recommend this product as a value for the price! I did receive a slight discount for honest feedback.  If you are in the market this product could work well for you! You won't regret buying these I assure you.

I liked the head lamp because of the light weight and quality of craftsmanship. The weight feels good when 3 AA batteries are installed and fits comfortably on my head. The light is extremely bright and has 3 settings plus wide angle to zoom (about the size of a half dollar coin). The batteries are very easy to install, and the head strap is easy to adjust. The light is made of a quality light weight aluminum. I have had few cheaper head lamps that do not even compare to the quality of this. I will definitely be purchasing a few more of these for my sons (both of which are avid hikers / campers) I have only used this product for a few days but it has already made it to my jeep console. It also comes with a protective vinyl carrying case ( which I like very much) I did receive the head lamp at a discount.

Great headlamp, very very bright, and comfortable.  The focusing mechanism is simple, just requires a push or pull to get the desired FOV.  The only slight improvement I could suggest for the next design would be to remove the red ring around the "barrel" of the light...it does bleed into your eyes and makes it a little harder for your eyes to adjust.  But a simple piece of black electrical tape fixes that.  All in all a very good buy!

This is a great light. I have two, one on my handlebar and one on my helmet. It makes the helmet a bit heavy, but is a better solution than a single brighter light.

I think the output of this light is, if anything, overkill for a lot of uses. I often use the low settings, but it's nice to have a ton of light when needed for descending fast on dark back roads.

A word of caution: the brightest modes, particularly the flashing, are really extremely bright and will confuse/annoy motorists unless you reserve them for daytime or keep the light pointed well down at the pavement. Be nice.

Great light...super bright. smaller sized battery. easy to mount to both handlebars and helmet. battery life indicator is a nice touch.

This is the PERFECT headlight for me! This is a serious headlight that could be used for many different applications with its five different levels of brightness. Don't let its size fool ya, this little light of mine is very, very BRIGHT on its highest setting.

This thing is awesome, good balance between  long battery life and very bright light.  I like that I don't have to click through all the various modes to shut it off, if it's been in one mode for a while it goes straight to off with one button tap.  The red is much dimmer than the red on my $20 Walmart headlamp, but honestly who needs the red to be bright?  I use red to check my camera buttons etc when I'm shooting the milky way and don't want my eyes to adjust back to brightness.

I'll update when I've used it to death,  but until then I'll be hiking all over at night with this thing.  Much more lightweight than the aforementioned one,  with better battery storage/placement. More comfortable on my big head for sure!

This is the best head light I have owned. Recently, I purchased 3 different highly rated head light products. I liked this one best and bought a second one. Brightness is great especially for the red light option. What sets it apart is that red has a separate button!  No accidental blindness or need to scroll through to get to red. Highly recommend this product.

The Active Research Ultra Bright Headlamp is just that - Ultra Bright!  It comes with 2 batteries for you which is great!  I found it to be easy to insert the batteries.  It fits very well, stays securely on my head and is easily adjustable. It has 3 different modes - solid white light, red light, and strobe white light.  I love how the lamp can be angled so you can shine it exactly where you need to see.  I use this headlamp to ride my bike at night, I can easily see the road in front of me now.

best head lamp light by far.  Battery does not last long though.  I bought 2 Li-ion 14500 750mAh batteries for it thinking they would last longer than a standard AA but the 145000 just is brighter.

I really like this headlamp.  Very simple and very bright.  I actually love how dim it can go.  You don't always need a spot light.  It is nice to adjust it way down.

I love this light. It is used almost daily at work and is very bright. If you manage to get a newer HC50, it is actually 760 Lumens. Battery does not last very long on high, which I knew from researching it, so pick up and extra battery and a charger, I like the 110V 2 bank one. Has several intensity modes, red leds, and the switch tells you the battery life.

Great light. Head can be adjusted. To turn it off/on hold the lowest power setting continuously.

i was worried about how big the head strap were going to be, but when i finally got them it is highly adjustable and the brightness was awesome. The LEDS are extremely bright and help out during dark situation while doing work, i would highly recommend buying this headlamp if you need one!
