I had trouble finding a review on the KR4. So far I can only add first impressions.
I’ve had my Emisar K4R for two days-and-nights now, so I’m ready to share first impressions.
The KR4 is a little bigger than a LumenTop FW3A: taller, thicker, and heavier. But than again, the KR4 is a quad emitter and the FW3A is a triple emitter. Speaking of emitters, the KR4 has greater LED choices than the FW3A.
I work with electronics, in a production environment, for a living. My professional opinion is that the: build, design, and production qualities of the KR4 are superior to those of the FW3A.
That’s not to say the KR4 is a perfect handheld flashlight, or the perfect flashlight for me. I prefer the triple over the quad. The clip of the KR4 is a little oversized and loose. And, though I’ve had no accidental activations, the switch is a little too easy for me to activate. Lastly, the KR4 came without a spare o-ring for the lens. According to Hank, the proper replacement is “26*1.2mm”. Though he didn’t recommend a material or hardness in durometer.
I really like the grip texture of the KR4 over the smooth body of the FW3A; whose knurling is ineffective. I l-o-v-e the secondary RGB LEDs of the KR4. I believe those indicator LEDs to alone have more functions than a HDS flashlight. I really appreciate that the indicator LEDs can be configured in lockout mode as well. This only adds usability to the two stage momentarily output of the primary LEDs; when the light is in lockout mode. Due in no small part to the broad variety of emitter choices, the the KR4 is quite configureable as well. The clip can easily be exchanging for the included lanyard ring. Bye-the-bye, a good quality lanyard is also included with the KR4’s purchase price. And, due to the added girth of the KR4’s body, it tail-stands a little better than the FW3A. On the other end, a SS bezel is available for both flashlights; though I wish each had shallow edge scallops.
I hardly notice the FW3A clipped in my pocket. Whereas, I noticed the KR4 every time I sat down, but not when kneeling.
I don’t know of any possible plans for a triple emitter version of the KR4 - a KR3. All-in-all, I hope Hank makes a deep carry clip for his Emisar KR4. That will make it my new daily work EDC. I do know the possibility of LT making a single emitter Andúril 14500 flashlight; which could take over my dedicated flashlight pocket. In that case, the KR4 being easy to locate in the dark by its secondary LEDs, would be relighted to at-the-ready duty near the fuse box.
Time will tell.
