Princeton Tec has taken the smallest, most convenient item in its product line and made it better. With the introduction of the PULSAR II, Princeton Tec has taken the coin-sized PULSAR L.E.D. flashlight and added a constant on-off switch for those times when you need continuous illumination. Like its predecessor the PULSAR, PULSAR II can also be illuminated merely by squeezing its compact, lightweight body.

Fun, new colors! A two-way switch allows this tiny light to be used as a pinch light for intermittent use, or flick the switch for continuous burn.

Switch is soft but can be stiffened

I was looking for a sturdy light, with replaceable batteries, for my keychain. I was disappointed that the switch on this flashlight was too soft. I wondered if my experience was common, so I searched the internet and REI, and found these reviews mentioning the soft switch.

I decided to look at the inside of the flashlight, to see if I could stiffen the switch. The battery replacement instructions on the package gave me courage. Opening the case is not too easy because it is strong and tight. It requires prying all around with a small screwdriver. I carefully lifted off the top half. It seems like the LED is secured somehow, which is good, so it doesn't fall out. But you still need to be careful not to let the batteries fall out after you remove the cover.

Here is what I did to stiffen the switch:

After removing the cover, gently lift the thick wire (LED terminal) and bend it straight upward a slight amount, so when you let go it points up at a 10 or 20 degree angle (instead of lying nearly flat on the surface of the battery.)

Then carefully put the top half of the case back in place, lining up the little pins that need to fit into their matching holes, and squeeze it together. The case is made of amazing indestructible plastic, which is good, because it requires a lot of pressure to close it again. You have to pinch it from all sides to get it closed all the way.

I haven't had the light long enough to rate the durability or long battery life, but I am expecting they will be good.

Without a light...

I went rock climbing to Yosemite last Labor day and got stuck on the rock a little longer then me and my cousin anticipated. By the time we got to the top the sun had set and all we had was this light. It lit up the path just fine we used it for almost three hours strait.I still haven't changed the battery which is wonderful!!!
I have one on my key chain now to as well as an extra one on my harness...

I think everyone should have one.

The light beem is very bright and is easy to turn on and off. I have not had problems with the switch...I've had it for two years now...

Works well

I have a few of these - one on each pack and a couple clipped to my tents. They're small enough to almost use like zipper pulls, which means it's easy to have them around all the time. Bright enough for tent lights or to find your way around a campsite. The "II" version has a switch that allows it to stay on without having to keep thumb pressure and makes it useful as a tent light.

Looks Delicate But Performs

Just bought a few more of these for my wife's girlfriends. I first hesitated buying because the LED lamp seems so exposed and delicate. Previous recipients have successfully used these for two years on key chains and we all know how much of a test that can be. Immediate, intuitive operation is a must in this category. All our friends are grateful.

Great tiny light

I have been using these small clear bright lights on my key ring, clothing and bag zippers for years. I also have several to keep with personal items for travel. I always buy the model with the on-off switch. They last a long time. The batteries are difficult to change, so I usually just buy a new Pulsar II.

I carry this all the time

I carry this with me on a key ring, in my purse - all the time. When I need a quick light unexpectedly, it always performs. It bounces around and is scruffed against other things and has never turned unintentionally been turned on. Very convenient and reliable. I have given several as surprise gifts.

My Brightest Keychain Light

I'm a bit of a flashlight enthusiast, so I have a lot of similar items. This one is my favorite, and lives on my keychain for everyday use. Get the high visibility bright yellow version if you keep it in a dark purse or pack.

Princeton Tec Pulsar 2

I carry one on my EDC,its bright and the stay on option is a bonus. I can just turn it on and do whatever it is I need to do without having to hold on to it.
mike at Campmor on 02/02/2012

Good emergency light

I much prefer this version of the pulsar because of it's on/off switch. It sure beats squeezing if you have to keep the light on for more than a couple seconds.

unbeatable portability

great little light -- so light you can forget you have it, but good for myriad applications in most conditions. I've bought so many I should get a bulk discount.

Better Alternatives

I'd misplaced my old Photon Lights and picked this up this similar product on a whim a couple months ago while waiting in line. Worked fine on my keychain, although the flick switch was soft and the pressure switch was stiff/finicky. Still, it worked well enough most of the times that I needed it until I left it attached when wading in the ocean. The light (contacts, batteries) corroded and subsequently split open.

I probably should have read the package more carefully - however the Photon Lights I've used have been IPX7 rated for years and I never had any problems getting them wet. I noticed that REI also carries a Gerber Micro Torch that is rubberized and "looks" tough, but also makes no IPX claims and I'm sure isn't waterproof, which is too bad, since for the same price as the Gerber, there's a much better product available!

One fatal flaw

I put this light on my keychain and stuck it in my pocket. Some time later I pulled it out to find that the switch was turned on. I don't know how much battery was used up in the meantime.

Maybe mine is defective, but it takes almost no effort to slide the switch into the on position.

It's still worth having if you keep it where it won't turn itself on accidentally, or where you will notice it if it does. But I'll keep my old Photon Microlight II in my pocket.

Small but unreliable

I've gone through 2 of these, and I won't bother buying a third. I wanted a small emergency light to attach to my key ring, and the two-way (squeeze on and constant on) switch sounded great. But the switches broke in both lights after simply being carried around in my pocket for a few months. The lights became unreliable after only minimal switch use.
ronref at REI on 10/10/2007

switch ruins it

I love the light it gives,kept it on my keychain but,...it turns on too easily and when I needed it it was already dead because it turned on somehow.I will not keep one again on my keychain. I am using another one now.Too bad. I would rather have the old style without a switch.
billykay at REI on 08/08/2012

better choices

Bought this light to replace a pinch-only model. Unfortunately the switch is both hard to use and unreliable. Most of the time the switch fails to turn the light on at all. Recommend choosing another brand. That's what I'm going to do.

Neutral Reviews:

It's okay, depends on usage

It is small but is very bright. You can squeeze it to get light or use the switch. It doesn't have the best way to attach it to something but it would work on a key ring or maybe a zipper. I figured out a way to attach it to my purse. Haven't used it a lot yet, only had a short time. I do like how bright it is. Just wanted something to use in the dark when I need it. I'm not a camper, hiker etc.

Replacing battery damages "switch"

Switch is sometimes erratic on new lights and becomes so after battery replacement. Replacing the battery is problematic: the "switch" is simply a plastic slider that presses one of the LED's leads (a light-weight wire) against the adjacent battery terminal. This wire is soft and does not tolerate more than one battery replacement before the whole affair becomes intermittant.
PhilA at REI on 12/12/2011

Great to begin with, fading

Used to work well. Now the light is fading after 2 months use. Probably need to change battery or light.
