{"product_id":"the-signal-peak-sft40-triple-source-headlamp","title":"The Signal Peak | 2000-Lumen SFT40 Triple-Source Headlamp","description":"\u003cdiv class=\"product-narrative\"\u003e\n\u003cp\u003eA flashlight answers one question: is there light. A headlamp answers a harder one, which is what your hands are doing while the light is needed. That difference is engineering, not marketing. The Signal Peak is built around the assumption that the person wearing it is mid-task, mid-climb, or mid-repair, and that stopping to operate a switch is not an option. Ten emitters sit under one housing, and the interface is a rotary dial, a single button, and an infrared sensor that reads a wave of the hand. Nothing requires you to look at it.\u003c\/p\u003e\n\u003cp\u003eThe optical architecture is genuinely three instruments in one body. A single SFT40 emitter at 6000 to 6500 kelvin throws a spot beam that reaches 230 metres, which is the difference between seeing a trail marker and seeing a shape that might be one. Six CSP1919 emitters at 5000 kelvin produce a wide, even flood field for close work, where a hotspot is worse than useless because it hides everything outside its circle. Three HFL1-R red emitters preserve night vision and keep the beam from announcing your position. Spot and flood can run together, which is the setting most people end up leaving it on.\u003c\/p\u003e\n\u003cp\u003eUnder the LEDs sits a buck driver rather than a simple linear regulator, and that choice is why output stays flat as the 18650 cell drains instead of dimming in a slow slide from the first hour. The housing is AL6061-T6 aluminium at 87 grams without the cell, machined to 35.7 by 45.75 by 86.5 millimetres so it sits against the forehead without levering forward. USB-C charging means one cable covers the lamp and the phone in the same bag. Step-down regulation, aluminium, and a sealed body are the three things that separate a headlamp you keep for a decade from one you replace every season.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eLight is not the product. Keeping both hands free is.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003chr style=\"margin:26px 0;border:0;border-top:1px solid #eee;\"\u003e\n\u003cdiv class=\"product-features\"\u003e\n\u003ch3\u003eDesign Notes\u003c\/h3\u003e\n\u003cul style=\"list-style:none;padding:0;margin:0;\"\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;font-size:15px;color:#333;\"\u003e✦ Triple light engine: SFT40 spot, six CSP1919 flood emitters, three HFL1-R red emitters\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;font-size:15px;color:#333;\"\u003e✦ 230-metre beam distance from the 6000-6500K spot channel\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;font-size:15px;color:#333;\"\u003e✦ Buck driver holds output steady as the cell voltage falls instead of fading linearly\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;font-size:15px;color:#333;\"\u003e✦ Infrared gesture sensor changes brightness from a single wave, even through gloves\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;font-size:15px;color:#333;\"\u003e✦ Rotary switch cycles light sources without requiring you to look at the housing\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;font-size:15px;color:#333;\"\u003e✦ AL6061-T6 aluminium body at 87 grams without battery, USB-C rechargeable\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;font-size:15px;color:#333;\"\u003e✦ Spot and flood can run simultaneously for near-field work with distance coverage\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product-specs\" style=\"margin-top:26px;\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul style=\"list-style:none;padding:0;margin:0;\"\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;font-size:15px;color:#333;\"\u003e\n\u003cstrong\u003eSpot emitter:\u003c\/strong\u003e 1 x SFT40, 6000-6500K, 230 m beam distance\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;font-size:15px;color:#333;\"\u003e\n\u003cstrong\u003eFlood emitters:\u003c\/strong\u003e 6 x CSP1919, 5000K wide-field\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;font-size:15px;color:#333;\"\u003e\n\u003cstrong\u003eRed emitters:\u003c\/strong\u003e 3 x HFL1-R for night-vision-safe output\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;font-size:15px;color:#333;\"\u003e\n\u003cstrong\u003ePeak output:\u003c\/strong\u003e 2000 lumens\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;font-size:15px;color:#333;\"\u003e\n\u003cstrong\u003eDriver:\u003c\/strong\u003e Buck driver with regulated output\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;font-size:15px;color:#333;\"\u003e\n\u003cstrong\u003eBattery:\u003c\/strong\u003e 1 x 18650 lithium, included\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;font-size:15px;color:#333;\"\u003e\n\u003cstrong\u003eCharging:\u003c\/strong\u003e USB Type-C\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;font-size:15px;color:#333;\"\u003e\n\u003cstrong\u003eBody material:\u003c\/strong\u003e AL6061-T6 aluminium alloy\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;font-size:15px;color:#333;\"\u003e\n\u003cstrong\u003eDimensions and weight:\u003c\/strong\u003e 35.7 x 45.75 x 86.5 mm; 87 g without battery\u003c\/li\u003e\n\u003cli style=\"padding:9px 0;border-bottom:1px solid #f0f0f0;font-size:15px;color:#333;\"\u003e\n\u003cstrong\u003eControls:\u003c\/strong\u003e Rotary switch, push button, infrared gesture sensor\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product-applications\" style=\"margin-top:26px;\"\u003e\n\u003ch3\u003eWhere It Belongs\u003c\/h3\u003e\n\u003cp\u003eThe use case that sells this lamp is not camping, which is the use case most headlamps are marketed with. It is work that requires both hands in the dark and a clear view at two distances at once: a mechanic under a chassis who needs a wide field at the bolts and a spot at the far end of the bay, a night fisherman re-tying a leader while watching the water, a caver or climber reading a route above the reach of a handheld beam, a homeowner tracing a fault through an unlit crawlspace. The red channel exists for anyone who needs to preserve dark adaptation, from astronomers to hunters moving before first light. Because output stays regulated, the beam does not quietly degrade halfway through the task, which matters more than peak lumens on a specification sheet.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product-faq\" style=\"margin-top:26px;\"\u003e\n\u003ch3\u003eQuestions, Answered\u003c\/h3\u003e\n\u003cdiv style=\"margin-bottom:16px;\"\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How long does the battery last?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Runtime depends on the selected output level and whether spot and flood run together. Expect roughly two hours at maximum combined output and well beyond a full night at the low and red settings. A spare 18650 weighs almost nothing and removes the question entirely.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom:16px;\"\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I use my own 18650 cells?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Yes, provided the cell is a genuine high-drain 18650 rated for the current draw.
