The Quark Aspheric Lens Kit allows you to convert your Quark from a reflector-based light to an aspheric-based light. The white Delrin reflector (machined in-house) helps generate some spill, allowing you to see nearby surroundings while throwing a ton of light down range. \u003c\/p\u003e\n\u003cp\u003eOur aspheric was custom engineered by a specialty optics firm for this specific application. This is the tightest beam you can get in a package this small. \u003c\/p\u003e\n\u003cp\u003eWe include 2 lenses because the front of the aspheric is slightly proud of the bezel. Nope, not ideal, but an engineering limitation in this application. If you use the light a lot, you'll need to replace the lens eventually, and we have you covered.  \u003c\/p\u003e\n\u003ch3\u003eAspheric Lenses: \u003c\/h3\u003e\n\u003cp\u003eAn aspheric lens projects an image of the LED die, much like how a slide projector works. It does \u003cstrong\u003enot\u003c\/strong\u003e gather scattered light like a reflector does. Therefore, the accurate measure of aspheric light performance is distance and not lumens. \u003c\/p\u003e\n\u003cp\u003eAspherics are common modifications in the custom flashlight world. Like a reflector, the larger an aspheric is, the tighter it can focus the beam. The Quark ashperic is quite small, but still generates a very useful cone of light that increases maximum throw by 30m. (reflector range is 170m and the aspheric is 200m) \u003c\/p\u003e\n\u003cp\u003eIn fact, the QK16L is only putting out 350 lumens with the ashperic compared to 700 lumens with the standard reflector...yet it still achieves longer range. See, lumens aren't everything ;) Side note, you'll see many aspheric lights that boast impressive lumen output. This is bogus. All aspherics will have low lumens, so the LED might be putting out 1000 lumens, but only 40% of those lumens are actually leaving the light. It doesn't really matter, but I still believe accurate specifications are a necessary practice of good business. \u003c\/p\u003e\n\u003ch3\u003eWhy this works so well: \u003c\/h3\u003e\n\u003cp\u003eThe real magic is the hexagon shaped LED die of the Nichia 319A. Yes, I was planning ahead on this one ;) Normally LEDs are square, and when coupled with a fully focused aspheric, projects a square beam. This is cool, but quite distracting for actual use. If you want a round beam with a square LED, you have to de-focus the lens, which reduces overall distance. The hexagon shape is round enough that the beam feels quite natural (even at very close range) and allows us to maintain 100% focus (maximum distance). \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eQK16L Throw:\u003c\/strong\u003e 170m\/\u003cstrong\u003e200m\u003c\/strong\u003e (reflector\/\u003cstrong\u003easpheric\u003c\/strong\u003e)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQK2A Throw:\u003c\/strong\u003e 145m\/\u003cstrong\u003e180m\u003c\/strong\u003e (reflector\/\u003cstrong\u003easpheric\u003c\/strong\u003e) \u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Foursevens","offers":[{"title":"Kit (1x diffuser + 2x lenses)","offer_id":30283096359025,"sku":"QUARK-ASP-KIT","price":28.0,"currency_code":"USD","in_stock":true},{"title":"2x spare lenses","offer_id":30283096391793,"sku":"QUARK-ASP-LENS","price":18.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1356\/1883\/products\/aspheric-components.jpg?v=1594005580"},{"product_id":"quark-conversion-bodies","title":"Quark Conversion Bodies","description":"\u003ch1\u003eQuarks are known for versatility\u003c\/h1\u003e\n\u003ch3\u003eMake your Quark the light you want it to be\u003c\/h3\u003e\n\u003chr\u003e\n\u003ch3\u003e\u003cstrong\u003e\u003cspan style=\"color: #cc0000;\"\u003eThese are Conversion Bodies ONLY: Flashlight not included \u0026amp; battery not included !!! \u003c\/span\u003e\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan style=\"color: #cc0000;\"\u003ePlease see the compatibility chart for battery guidance. \u003c\/span\u003e\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cspan style=\"color: #cc0000;\"\u003e\u003c\/span\u003eThese Quark bodies should be compatible with every Quark ever make, including the newest MKIII Series.
