## 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: Perfect EDC pen light - 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.
Review: Your best little helper EDC packs a PUNCH in a lightweight, compact, durable rechargeable EDC👌🏽 - 2-year review: STILL my #1 EDC flashlight! I wish I could give 10⭐'s out of 5 because I would. From the insane durability to the high quality case and body; to the rechargeable battery to the perfect fit! 👌🏽 This hits every mark I had and some I didn't even know I needed. I work in a rehabilitation center and regularly get called to search for "contraband" in tight places. This little guy has never failed me. It is so bright I often only need the low setting to get done what needs done. The charge lasts for hours -even on high! Overall I have no complaints. The only slightly negative thing about it, and this is just preference- is the micro USB instead of the USB-C connection. But I bought this over 2 years ago so it may have been updated since. The brightness is 5⭐, weight is perfect and case(body) is durable metal, also 5⭐. The kicker for me is how compact it is for such a great, would, rechargeable EDC flashlight. 10⭐/5👏🏽

## 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

### ⭐⭐⭐⭐⭐ Excellent Product!
*by H***N on September 6, 2009*

I've only owned the pen light for a couple of days now, but so far I love it! I've gotten used to carrying a small LED flashlight around with me. It's amazing how often a flashlight comes in handy (looking for something on the floor of a movie theater, on the floor of your car, etc...). It's just a great tool to have. LED light is so bright and clear, it really helps you see more than traditional lights. It's such a step up from the old yellow flashlights of our past. I bought two small'ish high quality Leatherman flashlights at Costco for $25-$30 each. I also bought two not-so-high quality flashlights at Sam's Club for $28 (package of two). I'd either keep one in my car or take it with me when I go wherever I went. Therein lies the problem. Carrying a flashlight, especially a well-made one (i.e. heavier), is a pain. It's very difficult if you're just relying on your pockets & hands. It's easier if you carry a backpack or a man bag, but that's not always practical. Anyway, a flashlight was always just another thing I had to carry (iPod, Flip video, cell phone, wallet, keys) wherever I went. Living in the Midwest, we have very cold winters and very hot/humid summers. I'm not a fan of leaving electronics in freezing or sweltering vehicles, so I always have to truck everything around with me. Well, thanks to this pen light, I have one fewer thing to carry. Sure, it still has to go with me, but I hardly know it's there! Obviously it's the size of a pen, so it's very small. It's also very lightweight. The light is extremely bright, much more than I'd expect from a product this size. Just stick it in your pocket and go. It feels like it's very high quality, and will hold up with more than a few drops (not that I'd recommend dropping it, but it happens). Be careful with the holster. It comes very tight and will grip onto anything. At the movies this weekend, I ended up using the light for something, and then attached the holster to the leg of my shorts. When I stood up (and the light stayed firmly in place), I decided to pull it off my shorts leg. I wasn't thinking. Make sure you gently slide it off whatever it's clipped onto. I ended up pulling it out more than sliding it down, and it bent the holster out a bit. Now it's not as tight as it was when it came, and will no longer grip onto just anything.
