Yes, BLF Q8 is the first lamp with Narsil, besides custom built ones.
If you want to mod a few members sell driver.
A few are mentioned in the NarsilM Thread NarsilM - configurable e-switch firmware for Multi channels, v1.3 in the first post.
The Emisar lamps (Emisar D4, Emisar D1, two lamps will follow) have a firmware derived from an older Narsil version without the modes part. Tom E wrote firmware version 1 and Toykeeper added stuff to version 2.
You can buy this lamps at Mountain Electronics and intl. outdoors now. http://intl-outdoor.com/emisar-d4-high-power-led-flashlight-p-921.html
Review from Toykeeper about D4
The next lamp with NarsilM will be the BLF GT, a group buy about a thrower. You can still participate for $150 a piece. Lumintop makes the lamp and want to release before Christmas 2017.
The FW3A is a small triple with a smaller head than the D4
This could fit for you JK.
Again a group buy in the early stage, no prototypes today. Produced by Lumintop. Finish can be only guessed. Maybe mid 2017 (+/- 3 months)
$30
Toykeeper about the FW3A compared to the Emisar D4
As you know GB lamps can have issues they are the first prouction run.
Thats it, only one pure NarsilM available.
But you can buy a lamp with electronic switch and change the driver.
Or similar UI:
D4 is a Quad, floddy, gets quick hot. Some call it a nut roaster
D1 is a pocket thrower with one Led.
Don’t forget to buy the short 18350 Tube if you like compact lights and a Aspire 1100mAh Battery.
For the rest you must wait
