Introduction: The FW3A was designed by Fritz 15 & the flashlight forums TLFBLF. Brought to life by Lumintop.A small 18650 triple LED lamp with tail switch & agreat, a compact, ergonomic, feature-packed EDC-style light. Specification: Emitter Three LEDs on a copper DTP MCPCB e.g.LEDColor temperature XP-L HI 6500KSST20 4000 K Nichia 219C 4000 K Optic Standard TIR optical lens Flux~2800 lm (XP-L Hi) Intensity~12 500 cd ANSI throw ~223 m (XP-L Hi) Firmware The FW3A uses free software called Andúril, distributed under the terms of the GPL v 3. Code is available fromhttp://tiny.cc/TKAnduril User interfaces[1] By default the FW3A is set to use SMOOTH RAMPING. Instant access to TURBO mode is also provided.[2]A more conventional STEPPED RAMPINGUI is available if youlike discrete modes level. You can choose how many steps you want[3]MOMENTARYmode is useful for signaling purposes or rapidly/brieflylighting up targets. To exit this mode, physically disconnect power[4]MUGGLEmode uses a reduced output.[5] It has an electronic LOCKOUTfor safety, but acts also as momentarylow light. Other functions: Battery check, sunset, beacontactical strobe, party strobe, bike flasher, candlelight, lightning storm Battery One flat-top or button-top 18650 cell. Anunprotected cell is recommended. Max. length 66 mm. Cell is not included. Driver FET+7+1 driver. Low parasitic drain while OFFBody: Aluminum with hard-coat anodizing Switch: Electronic tail switch Ingress rating Equivalent to IPX7 Weight Approximately 53 g without cells Size 25.5
