Pocket space is premium real estate, especially when your belt already carries a multi-tool, phone, and keys. The Streamlight Wedge SL attacks this problem with surgical precision: a 500-lumen flashlight that measures just 0.55 inches thick. For context, that’s slimmer than most smartphones, yet it delivers inspection-grade lighting that embarrasses bulky cylindrical torches.
THRO Mode Delivers When It Counts
The standout feature here is THRO—Temporarily Heightened Regulated Output—which unleashes 500 lumens with an 80-meter beam distance. Press and hold the tail switch, and you get momentary access to serious illumination. This isn’t party trick brightness; it’s the difference between squinting at engine components and actually seeing what you’re diagnosing.
That beam distance translates to lighting up objects at nearly the length of a football field, making it invaluable for mechanics checking under vehicles or electricians working in crawl spaces. The C4 LED technology triples the intensity of previous LED generations, delivering professional-grade performance from a pocket-sized package.
Everyday Modes Balance Power and Runtime
Beyond the burst mode, you get two constant-on settings that handle routine tasks:
- High mode: 100 lumens for 1.75 hours—plenty for detailed work without killing the integrated lithium-polymer battery mid-shift
- Low mode: 50 lumens but extends runtime to 3.5 hours, perfect for extended troubleshooting sessions
USB-C charging eliminates the proprietary cable nightmare that plagues older flashlights. Four LED indicators show battery status, from solid green at 75-100% down to flashing red below 10%. The TEN-TAP programming lets you set either high or low as your default with nine rapid presses plus a hold—no cycling through modes you don’t need.
Built Like the Tools You Already Trust
The unibody design starts with machined aluminum and gets a Type II MIL-Spec anodized finish. At 1.14 ounces, it weighs less than most smartphone cases while feeling substantial enough to survive toolbox life.
The 5.65-inch length fits naturally in shirt pockets without the bulk anxiety of traditional flashlights. Available in black, coyote, and silver to match whatever tactical aesthetic you’re committed to.
Streamlight built this for EDC professionals who need serious illumination without compromising pocket space. The Wedge SL delivers exactly that—assuming you can live with relatively short runtime on high power and no user-replaceable battery. For mechanics, electricians, and outdoor enthusiasts tired of choosing between performance and portability, this slim powerhouse finally eliminates that compromise.
