## Description

Product Description Streamlight 66122 Stylus Pro Pen Light with White LED and Holster, Blue. A sleek pen light that conveniently fits in your pocket. Ideal for anyone that needs a compact, durable light to carry on a daily basis. From the Manufacturer Weighing just over 1-1/2-Ounce (with battery) and ready for the demands of professional use, the sleek compact 0.5-Watt LED stylus pro runs on two AAA batteries. Developed for multiple tasks across all markets, the hallmarks of this light are its compact durable construction, optimum beam output and a tail cap switch for single-handed operation. The stylus pro is machined from solid aircraft-grade aluminum alloy and is plated with a MIL-Spec Type II anodize finish providing excellent abrasion and corrosion resistance. The stylus pro also incorporates an internal polymer body liner and shockproof switch housing allowing for operation under the most extreme conditions. The light has been drop test verified above the industry standard of six feet and extensively field tested. The stylus pro incorporates an unbreakable polycarbonate lens and multiple O-ring design providing water resistant construction and contamination resistance. Utilizing the latest 0.5-Watt emitter technology and Streamlight's proprietary micro optical system (MOS), Streamlight engineers have produced this sleek, compact and light weight flashlight with optimized output and run time. The durometer of the rubber used for the tail cap switch boot has been chosen for superior tactile feel and designed to keep out any foreign matter.

Review: Powerful, Well Made, and Priced Right! - This is a tough, well-made flashlight that has many uses. Much has been written on this light already, so I will focus on main points of my experience and what I consider to be the best uses of this flashlight. High Quality: This flashlight is made of high-quality components throughout, from its anodized aluminum body, to its strong pocket clip, to its well-protected switch. The lens is scratch-resistant glass and the LED is rated for tens of thousands of hours, far longer than a lifetime of likely use. How many times have I replaced the bulb in my popular 2 AA battery mini light? Too many. This one should last a good long time. The AAA batteries that this one takes fit nicely with little (but some) movement if the light is shaken. The tail switch has a strong, positive feel to it and is covered by a sturdy rubber boot. The light is water resistant and has a rubber O-ring in its tail cap. Powerful Light: Though it is a small light and runs on AAA batteries, this throws off plenty enough light to find one's way around a dark room, house, basement, or office building. It is easily strong enough to check for critters 50 feet out in my back yard. There are many brighter flashlights out there, but for its size and battery type, this on is really good. While the beam cannot be focused or changed, the spill of light is reasonable and the center of the beam remains bright and compact at a distance. The light, to my eyes, is a clean white and not tinged with color. I have not tested this light continuously with new batteries, but the batteries do seem to last a long time with periodic use. Value: This one is always big with me. I can afford having nice toys, but I feel silly spending lots of scratch for something that only works marginally better. This excellent little light is a terrific value, but throw in a decent nylon holster and quality batteries and it's just outstanding. Personally, I don't think it is practical to wear this light with the holster, as it is so light that it hangs on just fine with its strong pocket clip. The holster makes for a nice storage device, though. Best Uses: To me, this is an ideal light to have anywhere you would want one for emergency purposes: The glove box of an auto, the nightstand, your office drawer. Ever been in a large office building when the lights go out? I have, and it's no fun. Keep this little baby in your office drawer next to the pens and pencils and it will give you more than enough light to lead you to safety through darkened offices and stairwells. This light takes up so little space - about the size of a mechanical pencil - that there really isn't a reason not to have one either on your person or in your immediate vicinity. Carried in your shirt pocket, you hardly know it is there. It is likewise handy to illuminate that flat tire in the middle of a rainy night, or to find that nut that you just dropped down past the manifold. Ladies, this is an excellent item to have in your purse or bag, too. Ever been camping and wanted to take a stroll to the loo without having to take the lantern with you? This little light is perfect for all those occasions. Could you get a light that throws off more light or lasts longer? Sure, and I've got those, too. But this one is so small, powerful, and inexpensive, I don't feel bad about getting a few of them to have around where I need them. Would I want to leave my expensive tactical flashlight in my desk drawer at work where it's likely to nicked by a coworker or cleaning crew? No. The beauty of this flashlight is that it is small enough to put anywhere you would need it and inexpensive enough that you feel you could. And, while it's not as powerful as some of the other, fancy lights you may have, it is more than powerful enough to do most of what you would want a flashlight for, especially in emergency situations. I've been using these for a while now and they have been reliable and tough. For performance, value, and durability, this flashlight is an easy five stars.
Review: very easy to carry daily -CREE LED should last a long ... - Pros -High quality construction -Very bright considering size and weight -Excellent value. for around $20 you should buy several of these. -Compact size. very easy to carry daily -CREE LED should last a long time Cons -The constant on botton can be difficult to push -everybody wants mine. If I'm being totally honest I have only had this flashlight for about a week. I'm not qualified to comment on the durability or construction on it other than to say I am not at all worried based on the other reviews and the feel in hand. This thing feels like it would survive a few deployments in a warzone. Which is almost definitely overkill for a pen light but not so much overkill that it hurts anything. The light is still under 3 ounces but manages to feel very sturdy. Supposedly it is all o ring sealed so it should be fairly water proof and shock resistant. I'm not going to fling it at any concrete any time soon but it gives me the impression it would be no worse for wear. What I can say without a doubt is that I love this light. I frequently get home after dark and I wanted a nice small flashlight I could carry to light my way. This thing is an excellent companion in that regard. It is light enough to go unburdened into my pocket and small enough to not really get in the way of anything. I suppose if you're a hipster or a woman and are accustomed to wearing pants so tight you barely squeeze into them it may be more of an issue but if that's the case you can always clip on the outside of your pants. There's really no excuses to not be able to carry one of these. I was also surprised how bright the Cree LED is. The description says 65 lumens but as many of us know not all lumens are equal. Streamlight does not appear to be deceptive when they say 65 lumens. This light is plenty bright for the size of it. It isn't extremely bright if you take size out of the equation so I wouldn't necessarily use it as your only flashlight around the house but it is purpose built and exceptional at its designated duty. Don't expect it to be as bright as your headlights and you should be plenty satisfied with it. The power button is a little difficult to click to constant on. That would be perhaps the biggest con I've noticed so far. I can still do it with either hand and I can forgive them for designing it that way because it was done on purpose. They make it very easy to lightly hold the button down for a quick momentary on burst but in turn make it difficult to get it clicked on to fully on. There's plenty of people offering suggestions and instructions on how to fix that if you don't like it but I accept it as part of the design and see no issues with it. I'm usually only using a penlight in short bursts anyway. If I needed more light I should be going for more flashlight as well. The only reason I even think it's worth mentioning is because older people or anyone with dexterity issues might not like it so much if they can't turn on the constant on mode. I don't think anyone that can open a pickle jar would have issues though. Overall I am very satisfied with this purchase. It has been my first Streamlight product but I can confidently say it will not be my last. I am very pleased with the product. I would and have already recommended it to friends and family members interested in a high quality light. This is a great, HIGH value option for something you want to carry every day. If you compare this to what you could at Wal-Mart off the rack for 15-20$ this light would run circles around any of their options. Buy one. I have no doubt you wont need another unless you lose it.

## Questions & Answers

**Q: What is the risk of radiation? Is it safe to do an eye exam with?**
A: The risk of radiation is type RG-2. This is a form of radiation caused by the Brightness of the LED. The Brightness can lead to Permanent Damage to the back of your eye (retina), which can cause one to enter a category of Blind.

For example: In the Entertainment Industry, for over 10 years, lighting professionals have been prohibited from looking directly at the LED while it's on, because this will immediately cause one to develop a category of Blind.

**Q: I'm having an issue with the toggle on/off switch. Where do I send it back under the warranty coverage?? Only had it three months.**
A: The switch on these 66118 lights are horrible. I had to replace the tail-switch every 12months @ 6.89ea. It was cheaper and faster to just order 2 new tail-switches here on Amazon than it was to send it to Streamlight for repair.

**Q: Can this be easily concealed in my prison wallet?**
A: It’s quite slender so it will fit in your prison pocket quite nicely. Although on some occasions I have noticed a slight discomfort.

**Q: Is this the 90 lumen version ? Or the 70 lumen version. Stream lights website promotes the 90 lumen and this says 70?**
A: The packaging says 350. The listing says 350. If you look up the serial number it should be 250, however the packaging matches packaging of those at 90 lumen. Very very fishy

### ⭐⭐⭐⭐⭐ Perfect EDC pen light
*by M***H on December 4, 2025*

Streamlight is one of the best in the business and for good reason. Rock solid construction and a perfect level of illumination. I use my streamlight stylus every day. So far still on the first set of batteries and I anticipate long battery life. Fits perfect in shirt pockets or in most pen/pencil pockets. I have heard people say the button can be difficult to fully click for continuous use, however I find the resistance to be quite useful as sustained use is rarely needed for my use case. When needed however the button does click into a continuous use mode. Overall the best EDC pen light I have used.
