This 3-in-1 EDC Flashlight Illuminates Things You Can't See, Thanks to a Built-In UV Light - Yanko Design

"The K1 packs three distinct light sources into a 110mm body that weighs less than 80 grams with the battery, and each source serves a genuinely different purpose. We're talking about a 1,000-lumen white LED, a green pointing beam, and a 365nm UV light, all controlled by a rotary magnetic switch that sits mid-body. At $54.90, it's priced like a solid single-source EDC light, which makes the feature set worth unpacking."

"The question isn't whether cramming three emitters into one flashlight is technically impressive. It obviously is. The question is whether it's actually useful or if it's the kind of feature bloat that sounds good in a product description but adds friction in daily use. Acebeam seems aware of this, because the switching mechanism is surprisingly thoughtful. The rotary dial lets you select your light source without cycling through modes you don't need, and the tail switch handles on/off and brightness changes once you've picked your mode."

"Let's start with the white light because that's what you'll use most. The K1 uses a CREE XP-LR 6500K LED that hits 1,000 lumens at turbo, with a throw of 223 meters and 12,432 candela of beam intensity. That's solid output for a 14500-powered light, though the turbo mode steps down after one minute to 650 lumens, then to 110 lumens after another 30 minutes. Thermal management is real, and that stepdown pattern is pretty standard for this size class."

The K1 combines a 1,000-lumen white LED, a green pointing beam, and a 365nm UV light in a 110mm body weighing under 80 grams with battery. A mid-body rotary magnetic switch selects the emitter, while a tail switch controls on/off and brightness, avoiding mode cycling and reducing daily friction. The white LED uses a CREE XP-LR 6500K emitter with a 223-meter throw and 12,432 candela intensity, with turbo stepping down for thermal management. The combination of compact size, diverse emitters, and a considered control scheme targets practical multi-purpose EDC use at a $54.90 price.
