The Streamlight Wedge SL is the thinnest, lightest member of Streamlight’s Wedge family – a precision-machined, ultra-thin inspection and everyday carry flashlight built for professionals and EDC enthusiasts who need reliable, high-quality illumination in a form factor that virtually disappears into a shirt pocket or work pants. The Wedge SL takes the flat-body concept Streamlight pioneered with the original Wedge and slims it down to its absolute minimum: just 0.28 inches thick, 1.14 ounces, and 5.65 inches long – making it one of the thinnest professional-grade flashlights on the market. Despite its ultra-slim profile, the Wedge SL is built from extruded aluminum alloy with a Type II MIL-Spec anodized finish and delivers a 500-lumen THRO® burst on demand, with a practical 100-lumen constant-on mode for sustained task work. The Wedge SL is engineered to be the light you always have with you – because it’s the one you’ll never notice carrying.

Impossibly Thin – Only 0.28 Inches
The Wedge SL is designed for shirt pocket and pants pocket carry in environments where bulkier lights get left behind. Machinists slipping a light into a chest pocket, electricians tucking it beside a pen, inspectors clipping it to a shirt collar, or plain-clothes officers keeping a backup light invisible in a trouser pocket – the Wedge SL fits where other lights don’t. The unibody construction machines the body from a single piece of extruded aluminum. The result is a flashlight with impressive strength without added weight.
THRO® Mode – 500 Lumens of Maximum Output On Demand
The Wedge SL’s standout performance feature is THRO® (Temporarily Heightened Regulated Output) – Streamlight’s exclusive burst technology that delivers 500 lumens and 1,600 candela out to 80 meters (262 feet) with a press-and-hold of the tail switch.
TEN-TAP® Programmable Switch
The Wedge SL’s tail switch is TEN-TAP® programmable, allowing users to set their preferred constant-on brightness level:
High (factory default): 100 lumens, 300 candela, 35-meter beam, 1.75-hour runtime
Low: 50 lumens, 150 candela, 24-meter beam, 3.5-hour runtime
Aluminum Tail Switch – Tactile, Durable, One-Handed Operation
The Wedge SL is operated entirely from the aluminum tail switch – chosen over a side switch for one-handed operation in any grip, and for compatibility with tactical carry techniques.
4-Level LED Battery Status Indicator
One of the Wedge SL’s most practical field features is its 4-level LED battery indicator located next to the USB-C charge port. Every time the flashlight is turned on, the indicator briefly illuminates to display the remaining battery level.
USB-C Rechargeable
The integrated lithium polymer battery recharges via the universal USB-C port built into the body.
Stainless Steel Deep-Carry Pocket Clip
The Wedge SL’s stainless steel injection-molded pocket clip is designed for deep carry. The clip provides secure retention, and is sized for both pants pockets and shirt pockets……From $63.80
