Review: Excellent Product! - 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.
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.

## 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

### ⭐⭐⭐⭐⭐ Great EDC light holding up strong after 2 years of constant use!!!
*by R***U on August 21, 2014*

Another UPDATE 9/19/2015-- This is still a great light. I have bought a couple of other more powerful EDC lights, but always go back to this one because it has only one mode. The output is about right for most everyday use when inspecting houses or working on something. The battery life is still very good. I have been alternating between 2 sets of eneloops and they work great. I still carry this everyday and its holding up great. The pocket clip is also still holding up good. I will probably continue to carry this light until someone comes out with a one mode 80-100 lumen light that will last 5+ hours. Buy this light, you will not be disappointed. UPDATE:2/21/2015 (almost a year old) This light is still working great, I still use it everyday. Only downside is they upgraded the light right after I bought mine, I have the 45 lumen. Battery life is still very good, I use rechargeable eneloops. I have had zero problems, and I literally use is 5-20 min everyday. I carry it at all times and the paint is worn off of it. I highly recommend it. i have carried this light for 5 months and it is great. I use it every day multiple times a day for work. it is pretty bright for its size and you don't have to fool with multiple modes like some other slightly brighter flashlights. The battery life is excellent, i use it everyday and just changed the batteries a month ago. Puts out more than adequate light for inspecting interior rooms, cabinets, under equipment, and automobiles. You can't go wrong with this light Update Jan 2016. Light is still going strong after almost 2 years of constant EDC and use. I can't believe I have actually kept up with it this long. I am still rotating the same four eneloop batteries that I bought with the light. I use this light constantly. Even though it's not the brightest light, I feel its still the best AAA penlight out there with its balance of brightness vs battery life. Even though this may sound crazy, I am able to use it hands free since it's light enough to put in my mouth like a cigar, but waterproof so I can lather it in soap and rinse it off when it's gotten dirty. I have even ordered this light for some co-workers Update Aug 2016- Light is still going strong on the original battery rotation. Only problems with it is that the pocket clip has weakened a little bit and it has fell out of my pocket a time or two, but otherwise it works flawlessly. I still use and carry this light everyday!
