Small but effective
Color: Red Beam Size: 1 Count (Pack of 1)
This little light is just what needed for my keys. It’s bright enough to look for things when I accidentally dropped them on the floor at night or in my vehicle. Works great when the outside light needs replacing and I come home late at night. I would buy this again.

Compact, brite red, small, light weight light
Color: Red Beam Size: 1 Count (Pack of 1)
LRI PRK Photon II LED Keychain Micro-Light, Red Beam by Photon: Mine is in s black cover. For a small light, and being a red light, it's pretty "bright" for red. Light weight, small, whereby so compact, for me - a good back up light for small uses. I wanted red light to protect my night vision, as I've had some needs. I'm getting a white light too. I'd luv a yellow too but can't find it yet. The switch to steady/constant takes a light but firm push up with your finger nail; Do not use metal on the switch or you will break the switch. Good quality. Use care, be gentle. For non steady light, just squeeze it. Cool lite. ... show more

Very versatile and good quality
Color: White Beam Size: Key chain
I ordered 3 varieties - a slightly more expensive LRI PWK Photon II LED white beam with variable intensity switch; a std orange beam and a standard red beam light. They all come with a clip. The PWK Photon comes with a lanyard, a standard ring clip AND an alligator type clip device ideal to insert any of these 3 types on to this clip to attach to the bill of a baseball hat. All 3 are very compact and appear to be solidly made. The white beam light beam intensity can be changed from faint to bright light and it IS bright make no mistake. After one excellent and technical reviewers comments, I found that the orange, red, and white lights each have their advantages and disadvantages depending on how you use them. In a dark room when you don't want to be too obvious nor lose your night vision the red beam is ideal. The orange is slightly more intense for similar purposes. The variable white beam LED is perfect for those outdoor grilling sessions when you've got a late start, its dark and the little lady is wondering when you are gonna grill the burgers for the family. No more trying to hold or position a flashlight, simply clip this little buddy on your hat bill and aim. Perfect burgers and 2 hands now are useful. So, the price is very reasonable around 8+ buckaroos so why not buy all three. Tack on another of Amazon's smaller item you've saved in your Wish List to get to the minimum 25 buck purchase and get a 4-some with free shipping. These are keychain-sized lights and fit in a key case or dangle with your other keys ready for use any time. I'm really impressed with all three. All of mine came in the OEM plastic packaging so no issues about refurb or knock-offs with my order. As others have cautioned, do NOT accept any of these lights if repackaged. Perhaps Amazon has been taking those complaints seriously and that is no longer an issue. ... show more

Micro-Light flashlight
Color: White Beam Size: Key chain
Excellent product. Very convenient to have on your key ring or wherever you like. Very small but provides a very bright light. Instructions included for changing the batteries when required. You can't go wrong with this mini flashlight.

The best EDC light .
Color: White Beam Size: Key chain
These where the best lights to bring at a rave . 25 yrs later I'm now looking for an EDC light to carry. It popped into my mind Photon light . I'm shocked nobody on YouTube has this light or knows about it .Last night my daughter came home at 2am she turned her phone light on, I said need light ? flashed the Photon she said "Eww" then I flashed it again she said "wow" the room lit up like a flash of lighting hit it . This little light is the best bang for your buck . The brightest light in my tool box and smallest . And yes the battery will outlast any flashlight with double A or triple A. ... show more

Great light, but newer model is better
Color: White Beam Size: Key chain
The Photon Micro-Light II is very small, hangs easily on a keychain, and shines brightly for a light smaller than your thumb. The light illuminates when you push a button with your thumb. While I like the light a lot and it works very well, there are a couple significant downsides to this particular model. First, to keep the light on when you remove your thumb, you must slide a tiny, tiny switch -- something that people with limited mobility will find difficult if not impossible to do. For most folks it's not hard, but for some it would be a concern. Second, changing the batteries requires you to remove four tiny screws with an extremely small philips head screwdriver (similar in size to a screwdriver for the screws in eyeglasses). I would suggest considering a more recent model by the same manufacturer, the Photon Freedom Micro Light [Tools: Flashlights], which addresses my concerns about the Photon II. Changing the batteries on the Photon Freedom does not require removing screws, the brightness can be adjusted, and the thumb button controls a number of lighting options without the stiff, ridiculously small sliding switch. Many color beams (including UV, IR) are available for both the Photon II and the Photon Freedom (you choose one color beam to purchase--you don't get several colors out of the same flashlight), and the newest version of the Photon Freedom with white beam boasts a new LED twice as bright as earlier models. Well over a year since purchasing several of these, the lights are still working. The light has been very helpful and convenient to keep in the car. I attached a small square of adhesive velcro (loop side) to the back of one of these lights, and attached a small square of the corresponding hook side of the velcro to the top of the steering column of the car (behind the steering wheel). The light is tiny, out of the way, and right where I can access it instantly to check a tire at night or check the engine. In sum, Photon II is a great little light, durable and bright. The newer Photon Freedom is somewhat easier to use and maintain and boasts more features. ... show more

fantastic and small
Color: White Beam Size: Key chain
I absolutely love this little light. I had also purchased a small light like this but I didn't like it because you always had to have two hands to turn it on. I have this light on my key chain and I don't even notice it. It takes only a depression of your finger to turn it on. Only one hand. It has a switch that you can click so that the light will stay on. Most of all I love that I can put it in my small Altoids can emergency kit with other items. The brightness is really great for this little guy and does disperse fairly well over a 180 degrees. So you could hang it up in a tent to get light generally all around. Not like a lantern but still very good. The only suggest and concern that I have is that when I packed this up in my Altoids kit I had to be careful that when I closed the lid that the light button would not be depressed otherwise it would drain the battery. The button is recessed a little so I just made sure that it was laying on something flat rather than an object that protruded so it wouldn't turn on. Not sure there is anything that could be done any different. It's one of the most useful emergency preparedness tools because it's so small and you would always have access to it. Also, I was worried about how to replace the batteries... it's not a big issue but does require a very small phillips screw driver and then a couple of coin type batteries to replace. I have had mine now for about 3 months and use intermittently and still no signs of dimming of the light. I have now purchased one for each of my family members. I'm sure my kids will put it through the destructive testing phase :) so I may have more input later. ... show more

Great little keychain light.
Color: White Beam Size: Key chain
This isn't going to light up a whole room, but it is brighter than what you would expect and works well for light duty emergency light. Carried my first one on keychain for around 20 years and only changed batteries twice. Finally had to replace it only because the hole the key ring goes through finally wore out. ... show more
