## Description

Product Description The job doesn’t pause when the lights get low. A technician crouches beneath a vehicle, tracing a harness tucked deep behind the firewall. An inspector walks a dim warehouse floor, scanning for labels and torque marks before shift change. A security officer checks equipment tags in the early hours of the morning. Each scenario calls for dependable, focused illumination exactly what the Streamlight Stylus Pro pen light Series delivers. Built for professionals who work in tight spaces, low light, or unpredictable environments, the Stylus Pro models all feature a brilliant 100-Lumen white LED that cuts through darkness with a clean, even beam. Compact and lightweight, each light clips easily into a shirt pocket or tool pouch, so it’s always ready when needed. Technicians, inspectors, industrial workers, law enforcement, and maintenance crews rely on Stylus Pro lights for everything from quick checks and equipment inspections to routine maintenance and emergency response. Crafted with durable aluminum bodies, tail cap switches, and powered by 2-AAA batteries, these pen lights combine portability with professional-grade performance. Whether you’re on the shop floor, in the field, or on patrol, the Streamlight Stylus Pro provides the everyday carry inspection light that keeps pace with demanding work. 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: 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.
Review: Awesome Penlight - I am a medical professional. I have, for years, used a dinky incandescent filament penlight. I had one that was bestowed upon me at the commencement of my medical training. That thing went kaput after about a year, and it was one of those lights that had an internal battery that could not be replaced after the battery dies. After working for a few years, I finally upgraded to a "nicer" penlight that allowed for the bulb to be changed out. It was an LED bulb which outputted a decent about of light (LED technology from 10 years ago). It didn't require me to change out the batteries often, but the design of the pen housing itself is ultimately where the light failed. The screw on cap was made out of plastic. Upon my 3rd or so battery change in 10 years, the platic screw-on top snapped clear off, leaving the penlight unsalvageable. Well, not completely. I scavenged the LED bulb and installed it on another light that I had. But it did not leave me with a penlight to use for work purposes. Enter the Streamlight 66118 Stylus Pro. It is about the same size as my previous penlights, so it fits into my labcoat pretty easily (I have the breast pocket with the stitching dividing the pocket with a small column for a pen). This thing emits a lot of light. I love it. It's a cold, whiteish-blue light - colder temperature than an incandescent bulb. It works for my needs, as it illuminates the insides of mouths when I am doing examinations, and I can see every little nuance, nook, and recess in the mouth that allows me to make an accurate assessment of my patients. My interns have even asked me about my light - they are constantly amazed at the amount of light my penlight emits. Also, I use a number of cleaning agents on the housing after working with my patients - to keep it disinfected. The penlight looks brand new. On an aside, there was a power outage in my hospital (I am fortunate enough to have an inner office within an inner office with no windows) and I could hear the auxillary power kick on for the lights outside my office. I used the Streamlight Stylus Pro to navigate my partner and I out of our office space and into the lit hallway outside, through 2 doors, without a problem. The light was so bright that I probably could have just set the light on my desk facing the ceiling and it would have illuminated our office enough for us to continue to work. I am also an avid outdoorsman, and I would not hesitate to use this light out of doors on camping/hiking trips. It sips power from the batteries (I use Sanyo Eleloops, put them into this light about 7 months ago, and I still have not changed them out). This light is a powerhouse, and I would not hesitate to purchase it again if I had to.

## 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

### ⭐⭐⭐⭐⭐ It's Not Every Day That Your Gear Impresses You --- 5/5
*by J***O on August 1, 2014*

I have had my Stylus Pro for over two years, and could not be more pleased. This flashlight was carried every day for the bulk of that time, to include work in a industrial factory, light outdoor tasks, and general day-to-day use. For its size, it is a 100% tank, awesome, great, all the above---rock star piece of equipment. The light output of this sucker blows away small single LED and cellphone flashlights. Recently, to great sadness, my Stylus Pro went missing in the middle of a cross country move. After much searching, it was found a few months later in a nook of the car. During that time, the batteries had corroded and somehow gotten jammed in the barrel. Instead of hitting them with some solvent and letting them sit over night, I decided to take off the end cap and drop it on my concrete garage floor. This did nothing. I decided to then abandon the drop method and resort to the throw method. After much frustration, the batteries were removed as well as half of the end cap threads on the main body. At this point, I just assumed the light was a loss and I got on Amazon to replace it. While I was waiting for the computer to boot up, I decided to file away the frayed threads, do some careful bending, drop some fresh batteries in there, and baby the end cap on. What do you know, the damn thing worked. I was pretty surprised and damn well pleased. After seeing the abuse this guy has survived over the course of two years, I would definitely recommend it to a friend. Its light output is somewhere in between an iPhone and a medium sized duty flashlight. You won't great insane illumination with this guy, but you will probably be surprised at the light it can throw. It's weight isn't noticeable in the pocket. As far as competitive options within its own brand, the Stylus Pro is much better than its smaller cousin, the Microstream. I would also say it's better than the Nano, but that is sort of its own class of light. It rides in the pocket much better than the Micro, and throws much more light out for its size. As far as my own issue with the corroded batteries, I can't say what caused it. They were cheapos from Amazon, and the o-rings look intact and flexible, so I would likely blame the batteries themselves versus the light. The pocket clip rides very deep, and has maintained its strength over my personal use--still showing impressive tension after several years. The on/off button is very positive and easily pushed with the thumb, or index finger with or without gloves. The beam itself has about a 8" radius at 10', without much dispersion. The beam is also more than capable of reaching out across a room or greater distances. The black coating has worn well, only fading on the edges of the textured areas. Overall--this light is a great EDC option. This isn't a duty carry light, but it's not meant to be. You won't be disappointed with this purchase if you are looking for a light to meet your everyday needs.
