65022 Stylus 2-Lumen Blue LED Penlight, Black | 2 lumens; runs on 3 AAAA alkaline batteries; multi-mode lighting; IPX-rated water resistant; impact-resistance tested

Awesome. Battery’s last long time too

I don't typically write reviews on products that I purchase from Amazon...but this one truly deserves it. First, the price was awesome ($14.78)!!! Second, it feels well built and is very comfortable in your hand (just the right weight). Third, the light output is amazing for such a tiny flashlight...and the blue color of the light is beautiful!! You can slip this in your pocket just like a pen so it's ready when needed. I am going to purchase a bunch more to keep in every room of the house when the elec goes out, and to put in the glove box of our cars. I had never heard of AAAA batteries before...in a silly way, they are cute! I have only had the pen for about 3 weeks now, so I can't report on the battery life, but for $15...well worth it even if the batteries didn't last that long.

I bought the blue beam for work purposes. The blue lights up well but not too bright. I've had the light for over a year and I haven't changed the batteries in it yet. I have dropped it on the roadside and did not realize it until the following night. After a good rain storm, went back the next night with my flashlight on the side of Interstate 95 searching for it. I found it, tested it, and it worked perfectly. Very good light for conducting HGN. Only thing better would be the HGpen which basically does HGN for you. Great price as well. Look forward to making more arrests with it.

This little LED pen is super handy for carrying around — lightweight, compact, and easy to clip onto a pocket. The blue light is bright enough for close-up tasks like reading small labels or working in low-light areas. The batteries last a decent amount of time, though I wish they were rechargeable instead of disposable. Overall, it’s a solid tool for anyone who needs a portable light source, and the pen design makes it more convenient than a traditional flashlight.

I use this for long exposure photography to make cool effects on the film, sort of drawing with light. it works well for that because it only turns on when you press the button, so it’s easy to control. Weird type of battery, I’ve never seen ones that small.

This is a super cool little pen I mean it’s not gonna throw the highest beam of light. It’s not a laser. It’s not a flashlight. It’s just perfect for the person that needs a real quick light up or somebody that likes blue light. And I love blue light 😃

Great stylus for SFST investigation. Durable.

Great for night time DUI investigations. Very bright.

Could give a better light.

Husband was thrilled with his gift.

Purchased as a gift. Recipient seemed very pleased.

not a small enough pin point light to large no good for my cat to play with

31/12/17 Not for me I am afraid. The light emitted was far too blue.
