Like I said above I have been using this light for over a year for at work. I have more powerful lights I use on my personal time. I work in construction, and I feel like having a light on me at all time at work and home is a must.
Brightness~ I have nothing to really gauge the brightness against, but I feel that it is a true 80 lumens or very close to that. The light is very adequate for use indoors, and is good for short distances outside. The Cri LED they use seems to do what they advertise. When looking at wiring, the colors always seem to appear to be true and are not bleached out like you might get with a intense white LED.
Battery Life~ The Terralux Lightstar 80 takes 2 AAA batteries, and lasts me several weeks if not more using it consistently for work on a almost daily basis. I believe there 5 hour runtime is true, I can not confirm that since I have not sat there and watched my flashlight run constantly for that amount of time.
Ruggedness~ I did not know what to expect when I got this light. This light was a replacement for a Streamlight Flashlight that cost twice the price, and I ended up breaking dropping it less than 5 feet. My particular Terralux Lightstar 80 has taken drops upwards of 14 feet onto concrete and remained on and still continues to work to this day.
Features~ The feature I like and find most handy is the Rubber Bite Grip, and you know what I am talking about if you ever have bitten down on a Aluminum Flashlight without it. I don't particularly use the momentary on function, but as a prepper I can see its uses. Having a momentary on is great for signaling, especially if you know morris code.
Cons~ This light seems to not always be the most reliable when it is at the end of its battery life. You can be using it one day, and have it not work the next. Check it the next day and the light is working again. This could be a switch issue, but I really do find this happens when the batteries have been installed for a long time. The design of where the pocket clip goes leaves the top of the flashlight sticking out of my pocket quite far. During my regular day I do lots of moving in all sorts of ways. I have accidentally on many occasions turned on and drained the batteries without even knowing I turned it on.
What my Terralux Lightstar 80 looks like after a year~
Yeah I bite down on that, from time to time...
I conclusion I find this light to be very adequate for me, and I can live with the cons which can probably be avoided with a battery change.
Suggested MSRP is $29.99, but can be gotten for half that price online at most retailers.
