Quad

For a low priced headlamp, this is a great product. Admittedly I don't have much experience with other headlamps, but this one makes me feel like I won't need to.What you get: This headlamp ships with the headlamp itself, and a set of three lenses (Red, Green, Blue), that you can use to change the color of the light emitted.Setting it up: The Princeton Tec Quad LED Headlamp is pretty easy to set up; to install the batteries you only have to remove one screw, which you can do without the need for a screwdriver, and then insert the batteries (it takes 3 AAA batteries). Switching out the lenses is a little bit trickier, and I can't remember whether there were any kind of instructions telling you how to. That being said, it's still easy to do. Simply pry up on the little tabs which can be found on either side of the power switch (I use the tip of a knife), and swing the cover forward. You can insert whichever of the lenses you want, and then close the cover until you hear the snaps of the tabs locking back into place.Use: The headlamp has three brightness levels and a strobe function. You press once for the lowest setting, and then press once for each brightness setting increase. If you press again after reaching the brightest setting, the headlamp begins strobing. To use whichever optional lens you inserted, all you have to do is slide it up over the white LED bulbs, and when you don't want the colored light anymore, you can just slide it back down. The headlamp also tilts forward and has quite a few different degrees of tilt that you can choose from. In my experience with it, the Princeton Tec hasn't once flopped forward on me, even after several high impact landings. It stays firmly in place, no matter what angle you've got it tilted at. The headband it comes with is a very comfortable neoprene/elastic feeling band. I've worn it with and without a hat so far and haven't had a problem with it being too big or too small (I've got a pretty big head). The white light is pretty far reaching (I'd say about 50 feet, which I consider to be far reaching anyway), and bright. The lenses take a little time to adjust to since they dim the light down, but they'll help you find your way while preserving your night vision capabilities.Con: There is one con to this headlamp, and it has to do with storing your extra lenses. The package includes a little clip that you can attach to the headband, and I've found it pretty useful for storing one of the extra lenses. I'm assuming that's what it's for, since I can't find any other purpose for it. The downside is that it only holds one. So if for some reason I need to use all of my lenses in one night, I'll be able to quickly switch out for one, but if for some strange reason I find myself needing the third, I'll have to go digging in a pocket or backpack for the tiny baggy holding the tinier lens. This isn't a big problem at all, since I don't foresee needing a red, green, and blue lens all in one night, but it just makes more sense to have them all in one place. It's not enough to knock off a star, just a mild nuisance.In summary, this headlamp is a great investment for anyone who might want to go on night hikes, play airsoft at night, or really do anything in the dark. It's definitely a more convenient alternative to a flashlight so that you can keep your hands free and still have light. It's comfortable, versatile, and very easy to use. I could open it up and install new batteries with gloves on and no screwdriver, which is a plus. Definitely would recommend, especially since it's list price is so low.

10/10 would recommend to anyone in Aviation.I always hated how most head lamps with red light were way too bright and it would create glare on my GPS, gauges and or make it hard to look for traffic without having to turn it off completely. Or the opposite and the product was just cheaply made, and I didn’t have the option to go brighter and I could barely make out the names on my switch’s. This head lamp is perfect, it feels like durability plastic, I can turn the brightness up to the highest notch when doing preflight. Then to the middle setting when I am on the ground to see all my switches perfectly. Lastly, when in cruise I can turn it down to the lowest setting so I can better see traffic; while not having any glare on my GPS and G5’s. All without once worrying that I am gonna be absolutely blinded by clicking a button wrong and turning on the white light like most headlights. Lol.

Used these while in military. Best model of the Princeton lineup imo.Mine took unintentional abuse, still worked. As a Feild combat medic, used profusely to treat wounds and throw sutures. Never let me down. Only complaint is battery life. That complaint is minimal as I wasn’t buying the batteries :)

I've been a fan of Princeton Tec's head lamps for a while, and this model is a great improvement on what was already a good line.It withstands the rain, it fits comfortably on your head, and it has a good range of intensities. By pressing the button multiple times, you can increase the intensity or select a flashing beacon mode. The red filter is a great addition for keeping your night vision. And speaking of night vision, one nice change from their previous models is the intensities start from the dimmest and get brighter with each press, not the other way around as before. This helps keep you from getting a bright flash in your face (or your partners) whenever you turn on the lamp.You can feel there's quality construction on the unit. They'll be in my packs for a long time.

I've had one of these for many years and use it for getting to/from my hunting stand in the dark. The light comes with one color filter, but you can get others from the manufacturer (as well as a clip-on holder for each of the filters you'd select that slide onto the head band). Filters come in red, green and blue. The blue was touted for blood tracking in the dark, but it's largely useless as it makes blood appear "black". It still gives a softer glow than than the white LED light itself. Plenty bright, solidly holds the lamp in multiple positions when tilting downwards. Battery change is easy. I'd recommend it.

The red lense the red lens cover would scratch after multiple uses. It was so weak, that you couldn’t even see the red light in the night time.

Love this thing. 3 settings for varied brightness plus a flashing signal setting. The low setting supposedly last for long hours and is fine for basic functions. The colored inserts preserves nightvision and is low enough to not attract unwanted attention. You can still see and even read with the red light. They flip up and down so any setting can be colored, but you can only have 1 color in the unit at time...you have to open it up and swap on the plastic color filter for green or blue.

I've had countless headlamps and hated them all. Bands were too tight. Got tangled in my hair. I'd forget how many times I needed to click a button or which one to switch to night vision.All that's in the past now.I took this headlamp camping and was happy at how easy it was to switch between white light and red light by just pulling down a red filter. Unlike other headlamps, because there's a filter for the red light, you can change how bright the red light is.If you're looking for a headlamp you can't go wrong with this one.
