Like many others I’ve been interested in nichias, for their supposed gorgeous tint and high CRI, and I’ve played a bit with the warm white 119 previously available at fasttech (my scratch build entry, the camera lux used one of those)
a while ago fasttech got Nichia NVSL219AT in stock (discussion about them here ), and I ordered a bunch.
Now I’ve used some of them for modding, and wanted to share some of the results!
Let’s start with the “SK98 clone”
this flashlight was quite boring, ugly tint, though resistor modded driver so it always started on high.
So I thought: “what if I try a dual nichia mod with this one?”
So i reflowed 2 nichias on a 20mm dual xp-* board and tried it. i liked it, but didn’t really want the “bug eyes” when focused, so i used a couple of 20mm boards as a spacer, and managed to get rid of the most annoying bug eyes, leaving only squares that would let you know that you’re using a dual led-flashlight. I also had to mod the ledboard retainer to accept the new led board.

now i like it much better! a nice feature of this flashlight is that if you zoom it halfway you get a rectangular hotspot!

i bought a bikelight from one of wallbuys crazy sales, but i have always thought it is too throwy for my bikelight preferences. the reflector is very similar to a c8 reflector, so there haven’t been enough spill for me.
I don’t own any DC-fix, but i did buy some matte/”invisible” tape, that i have covered both sides of the glass lens with for a much more diffused beam profile.
And since i liked my SK98-mod, i also modded this light with a dual nichia setup! a reflector based flashlight usually gets a nasty donut hole in the middle of the hotspot, but since the light is so diffused it doesn’t matter here!

i have bought some in the past when they’ve been very cheap. can’t say I’ve used them much neither, and they don’t make too good mod hosts neither since they’re feeling a bit too cheap. they used crappy tinted xp-e, and had a tailcap draw of ~1A on high.
I think I’ve modded one with a NW XT-E once, but the tint shifted across the beam very noticeable, so i changed reflector for a frosted TIR, and had an ok flashlight for indoor use.
Another one had its led bathing in acetone, and had a bit tighter hotspot.
But when i got the nichias i reflowed them on 16mm alu boards and put them in the tube lights, and put TIR optics in them as well, one clear and one frosted:

My wife makes some silver rings and was going to sell some of them on a christmas market/fair, and needed some portable light. just using the flashlights would work, but i thought i could make them look better.
So i got some tree (probably some alder) that i bored out and made the flashlights fit into.
warm white light from a hanging piece of wood where the bark was left looked really nice! since the flashlights had low max amps and we used them outside and on medium i wasn’t worried of the insulating wood.
