quick and easy free hf 9 led mod 18650 hi cri

i am sure everyone here has these things around.this mod SHOULD be doable to most 9 led 3aaa light.
start by punching the board,lense,reflector out from the inside.i do it on a carpeted bench with a 3/4” extension.
the big end fits fine.lens down on the carpeted surface and tap it out.save lens for some other project as it is not used.
replace leds with the ebay hi cri 5mm i pointed out.their vf is perfect for dd.
i fold neg of 2-3 leds over board edge.do what it takes to get a very snug fit.
now sand the paint from the id of the led end of tube.
press led/reflector assy in leaving it protrude about 3/8”.
check fit of your flattop unprotected 18650.
ok?all leds work?
set board/reflector straight in the tube so it looks even.run bead of medium ca all the way around.let it wick into the space and zip kicker it.give it a spritz inside so no ca runs through.
roll up your strip of cardboard/whatever spacer you like.
you now have a rather odd looking but very good 18650 light for cheap.

optional step.
a bead of jb kwik around the board edge inside to dump heat to the tube and reinforce a bit.
