Optioned mine with NTG35 4200K X2, SST-20-DR and UV (at the cost of no aux LEDs) as a do-it-all light for nightwork, camping and taking photos of UV in nature. Very floody light good for illuminating <50m distances. If you want a a compact thrower, consider a D4Sv2 instead if you want a multi-channel light, otherwise a D1K or K1.
NTG35s have a nice rosy tint at 4200K that's easy on the eyes and has a decent warm spectrum, but if you're after perfect colour accuracy, consider selecting the 519a 5000/5700K instead. Changing channels and configuring tint ramps can be weird if you've only used Anduril in single channel lights before, so bear that in mind.
It gets hot pretty quickly running 2x NTG35s on turbo, but provides good runtime and heat management otherwise, and can run a single SST20-DR or UV on turbo for extended periods without overheating.
Also, get the magnetic tailcap. It's FAR more useful than you'd think. Raised button is easy to find in the dark.
The triple channel D4K is fantastic, I went with 519a’s in 4500k dedomed in channel one then deep red and deep blue in channels 2 and 3. If you are reading this review and for some reason you are still not 100% convinced just buy one already. This is my first Emisar and it will not be my last, it exceeded my expectations in every way, and my expectations were very high.
1st Time purchase here. Dark Grey triple channel D4K 1*21700. Use it for Non Destructive Testing of Aircraft Parts. This Light PASSED all legal requirements. Well over 100 foot candles of White Light, (Blacklight) 5000+ UV/cm2 with under 1 foot ca of background white light.
Most Blacklights at this range would cost 800-1000 USD.
