The Thrunite TN42 is worth a look for a larger thrower. I’d strongly recommend getting it in neutral white. It has a larger reflector and lower driver current than the K70, so it won’t get hot as fast; it has a boost driver for stable output as the batteries drain, while the K70 loses output as the batteries drain and it has a neutral white color temperature, which may[^1] reduce backscatter, making the target more visible. Try coupon code “20%”, and failing that “thrunite”.
On the compact side, the Emisar D1 is cost-effective and one of the most powerful throwers running on a single 18650. I suggest the 5D tint option, again due to backscatter.
I’ve reviewed a couple recent Klarus XT-series lights and have to recommend against them. The biggest issue is visible PWM flicker in lower modes, but they’re also a bit… meh otherwise. Here’s my review of the XT12S.
[^1]: I believe that it does, but some people dispute this, and I have not seen a test with unambiguous results.
