Another just because I could project. I converted an old 18v flashlight to an LED for lumen overkill with active cooling. The model used for the conversion was a FL1800 but it should be identical to the more common P700. Hardware Used:10watt 9v-11v LED packageMiniature 24v step-down converter30x10mm 12v fan38x10mm northbridge heat sink (remove mounting tabs)9x9x4mm heat sink (for the converter)M2.5 x 8mm screwsThe only component I actually bought for this project was LED and the rest was left over from other projects or salvaged.Assembly: Your mileage may vary but the rough assembly instructions are as follows. Measure twice and cut once are words to live by. Doing test fits before cutting, drilling or even gluing is recommended.Modify the shell:removing webbing (red)drilling air exhaust holes (yellow)drilling air intake holes (green)(optional) installing baffling (vinyl electrical tape) between halves (purple)Wire electronics (executive executive summary):adjust converter to output 9vuse thermal adhesive mount LED and converter to respective heat sinkssnip the bulb wires from socket connect existing negative to converter, fan and LEDconnect existing positive to converter onlyconnect converter output to both fan and LEDFinal assembly drill holes in shell and LED heatsink for bracket mounting on both halves of shellattach fan and duct to led heatsinkwill have to be rotated for screws to alignmount LED assembly to one side of shelltuck converter into rear portion of shell and route wires aroundclose shell with other half and mount other side of LED assemblyreassemble handle of flashlightplace cover over LED and thread flashlight outer cover onto it.
