    • Sleek and Powerful Penlight for Everyday Use
Style: Non-Rechargeable Size: 100-Lumen Color: Black
This Streamlight 66118 Stylus Pro penlight is a game-changer for me. The design is sleek and compact, making it easy to carry around in my pocket or bag. The 100-lumen brightness is impressive and provides a strong, focused beam of light. The inclusion of 2 AAA alkaline batteries is convenient and ensures I always have a backup ready. One minor drawback is that the pocket clip can sometimes feel a bit flimsy, so I have to be careful not to snag it on anything. However, this is a small issue compared to the overall performance of the penlight. In conclusion, the Streamlight 66118 Stylus Pro is a reliable and powerful tool for everyday use. Its compact size, bright light, and included batteries make it a top choice for anyone in need of a dependable penlight. ... show more

    • The best shirt pocket flashlight.
Style: Non-Rechargeable Size: 100-Lumen Color: Black
Been a diesel mechanic for going on 15 years. These are the best little flashlights you can buy. I like this model that takes AAA batteries over the rechargeable ones because when the batteries die I can just quickly swap them out. They usually last me about a year of regular hard use. Streamlight also has an excellent warranty. ... show more

    • This flashlight is a very well made tool.
Style: Non-Rechargeable Size: 100-Lumen Color: Silver
Review Image by G-MAN G-MAN
This is one of the best pen type flashlights I've ever owned. It's bright and doesn't eat up the batteries like most. I've had the blue one for over 6 years. I lost the blue one a couple years ago. Then ordered the silver one. After the silver flashlight arrived I found the blue one in my driveway. My truck ran over it and it was sunk down in the gravel and dirt. Took it in cleaned it off and worked fine, didn't even dent it Missing about two weeks. It's lightweight and waterproof. What I liked about it is I wear overalls all the time and it fits comfortable in my bib front pocket along with my pocket knife. I always have it with me and has come in handy hundreds of times I don't leave home without it. As for buying it again, just as soon as I thought the blue one was lost I re bought the silver one. I won't go anywhere without it. It's a durable product well worth the money. ... show more

    • Good small size but nice light
Style: Rechargeable with USB Cord Size: 350-Lumen Color: Black
My husband got this for work said it’s great to put in your mouth while you’re working on your car or something at night and need both hands. It’s light enough but has a strong bright light, he’s obsessed with it it’s small and compact but handy. Would make a great gift

    • Great little light
Style: Rechargeable with USB Cord Size: 350-Lumen Color: Black
Use this light daily at work, fits nicely in my Carhartt chest pocket. Excellent light for inspecting small spaces as it’s not too bright and doesn’t drown the area it illuminates with a white flash. I work in industrial electrical maintenance and it’s perfect for the application I usually keep it on the low setting. Highly recommend it after 2+ years of use and some abuse. ... show more

    • It does the job I purchased it for and it fits concealed in my shirt pocket.
Style: Non-Rechargeable Size: 100-Lumen Color: Black
I chose and purchased this penlight over the competition because the top of the clip is very close to the top of the light. This allows me to close my shirt pocket flap with the light inside. The diameter is about the size of a fat ink pen, so it doesn't cause too much deformity to my shirt. This is my go-to backup light for when my primary light source goes dead. It appears, and feels, rugged. I have been using it for several months now working night shift. It is bright enough to finish the job when your primary light quits. It has a pressure switch button on the cap that I wish was a regular on-off switch. I would like it better if it would stay 'on' if I drop it or my finger slips off the button. I would definitely buy this style again though. ... show more
