This is a great headlamp. I bought this light primarily to do turtle watching since the leatherback turtles do not see the colour red. However, I soon other uses for it, like hiking and reading star maps without losing my night vision for star gazing.

The four LEDs are great. The three light settings are great since you can choose the right amount of light for the situation. The emergency flashing light feature is great if you get into trouble and need to attract attention to where you are.

I especially like the fact that the red filter is attached to the light and can pivot into place when you need it. Won't be losing any more filters from now on. The head band is adjustable and made of a comfortable material so you can keep it on for long periods.

Overall this is a great light and comes with batteries. 5 stars

I fish the unforgiving rock piles of NJ, pretty much getting wet most of the time with waves crashing over the rocks and getting salt spray in my face. This thing claims to be water resistant, but it is not. After using it one time, the battery terminals corroded and the light is not working properly. If you are planning on being dry the whole time, than its a great lamp. Very light weight, the red lens is perfect for keeping your night vision, its just not good for surf fishing. 2 stars

I just got back from Yosemite, having now taken this little headlamp on four backpacks. It's almost perfect: the headband is comfortable, the rubberized indent for the on/off switch is easy to find in the dark, and the thing is very light. The red lens is a great idea; it provides enough light for many purposes (hunting down gear in a dark tent) while not blinding you. I could use this to gather firewood while still being able to glance up and see the stars.

I used it to drain some rechargeable batteries (I've been told recharging after a complete drain helps make sure they get a full recharge), and the lamp was still glowing more than a day later -- and this was after my GPS unit had rejected the batteries as uncharged. The headlamp wasn't glowing brightly by then, but still...

My only cons:
* Like most similar headlamps, when you first press the ON button, the brightest setting comes first, then you repeat the push to get to dimmer, dimmest and flashing. It would be nice if the order, instead, was dimmest, medium, brightest, flashing. That way you don't get blinded by the high beams when all you wanted was the dims.

* The battery compartment is very, very tight. It can sometimes be awkward to keep all the batteries in place while the lid is levered back on. The batteries tend to pop out if you don't get it just right.

* In a pitch black tent, you'd better remember where you put your headlamp. It would be very nice if this had a glow-in-the-dark highlight somewhere that would make it easier to find. For example, the zipper pulls on my North Face sleeping bag glow for hours and hours after dark. I'd rather have that glow on my headlamp. 5 stars

Great Headlamp... I use it daily... My sister got me hooked with this model... she uses them every night out in the Serengeti. I especially like the quick flip design of the red lens. If I wake up in the middle of the night I use the red lens to preserve my night vision (and not wake my wife!) I have bought 3 of these for friends and family - my father uses his all the time with his telescope (with the red lens). The batteries last a very long time and taper off slowly... never leaving you without light. 5 stars. 5 stars

I love my TacTikka Plus Headlamp. It has all of the features you could possibly want. I use mine hiking, camping, for home repairs, and even for reading in bed with the red filter. This product is highly effective and simple to use. Good job Petzl! 5 stars
