This fixed-focus optical design channels up to 2100 lumens into a tight hotspot that reaches beyond 680 meters, delivering the long-range performance required for trail navigation, property security, and off-road driving without wasting energy on wide spill patterns.\u003c\/p\u003e\n\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S3e9104385f3546808a0c2d51faf1fc8do.jpg\" slate-data-type=\"image\"\u003e\n\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/Sa39a7d5f2d7b4b29a04cc6ac8e74fa7bw.jpg\" slate-data-type=\"image\"\u003e\n\u003cp\u003ePower and efficiency come from a dual-circuit system built for sustained output. The high-density DTP MCPCB board regulates current across a 2.8 V–4.5 V operating window, while the integrated USB-C port allows direct charging from standard power banks, laptops, or wall adapters. A single 21700 lithium-ion cell drives the unit, keeping the overall footprint compact at 127.1 mm in length and a 42 mm head diameter.\u003c\/p\u003e\n\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/Sdf3f943b566e4cd1941ed6d9331369c9O.jpg\" slate-data-type=\"image\"\u003e\n\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/Ha3b6ccf8c6514571a6092ad57427c800X.jpg\" slate-data-type=\"image\"\u003e\n\u003cp\u003eSustained illumination depends on intelligent thermal management rather than raw wattage. Sofirn’s Advanced Temperature Regulation (ATR) continuously monitors the SFT40 diode during operation. Once the emitter reaches a predefined safety threshold, the driver automatically steps down output in controlled increments, eliminating sudden blackout cycles and extending component lifespan during prolonged high-output runs.\u003c\/p\u003e\n\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/H566c3eb981654f5ba1b59e4fab50e3abW.png\" slate-data-type=\"image\"\u003e\n\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/H4d60d742709d493284f328b72188f3a0w.png\" slate-data-type=\"image\"\u003e\n\u003cp\u003eEnvironmental durability matches the technical specification. The aerospace-grade aluminum alloy housing withstands daily handling impacts, while an IPX-8 rated seal guarantees complete submersion resistance up to two meters. The mechanical tail switch offers five selectable stepping modes plus continuous stepless ramping, allowing immediate brightness adjustments without navigating digital menus.\u003c\/p\u003e\n\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/H54eb6211418d42c0bd25d8dcef16f7d9P.jpg\" slate-data-type=\"image\"\u003e\n\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/Hd09abfea25a14e8fa1d816c44fd328d1l.png\" slate-data-type=\"image\"\u003e\n\u003cp\u003eThe unit arrives as bare hardware, weighing just 120 grams without an installed cell. Standard packaging includes a USB-C charging cable, replacement O-rings, a lanyard, and an instruction booklet. Customers requiring immediate deployment can select the battery kit bundle, which ships with a 5000 mAh 21700 cell pre-loaded and ready to insert. The precision-molded TIR lens features a minimal factory seam along the barrel junction; this manufacturing characteristic ensures proper optical alignment and maintains the IPX-8 watertight standard.\u003c\/p\u003e\n\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/H2042c60ed97a42a3aef0a68dfbe0860dz.jpg\" slate-data-type=\"image\"\u003e\n\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/H8097c9274e4241e1aae98f77ded4cee8d.png\" slate-data-type=\"image\"\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/H55d43f0f97f74c68b914d6dd044bb31cJ.png\" slate-data-type=\"image\"\u003e\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Seek 4 Home and More","offers":[{"title":"with 21700 battery \/ 6000-6500K \/ United States","offer_id":52864063799583,"sku":"136:200002572#with 21700 battery;200007763:201336106;5:100014064#6000-6500K","price":59.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0969\/0447\/9007\/files\/S5c80a20a9f6a4fae90e044b7ce48d167E.webp?v=1788916757","url":"https:\/\/seek4homeandmore.com\/products\/sofirn-if22a-2100lm-flashlight-21700-powerful-light-sft40-led-680m-long-range-usb-c-rechargeable-charging-throw-torch","provider":"Seek 4 Home and More","version":"1.0","type":"link"}
